3 Things Sider AI chatpdf Does Well

• Automated Pull Request Reviews: So, one thing you get is automated review for all your open pull requests right in one spot, which kind of keeps things together and saves you some trouble jumping around.
 
• Multiple Organizations and Projects: You can toss in more than one organization and even a bunch of projects into your account, which is handy if you work with a few different teams or groups.
 
• Branching from Dashboard: The tool lets you start new branches right from its dashboard, so you don’t have to hop over to another screen just to branch out your work.
 
• More on what makes Sider AI chatpdf great below.

5 Worst Things About Sider AI chatpdf

• Terrible Customer Service with Refund Hassles: If you ever try to cancel or ask for a refund, good luck getting help. The support folks basically ignore you, and you end up stuck paying for something you don’t want.
 
• Wasted Money on Disappearing Credits: You might think you’re getting a great deal on their subscription, but unused credits just vanish every month. So you’re always overpaying for stuff you never even used.
 
• Misleading “Unlimited” Plans: They call it “unlimited” but it’s really not. You get a fixed number of credits, and when you use them up, you’ve got to pay even more. So you end up spending way more than you expect.
 
• Tool Quotas Change Without Warning: Sometimes, they just change how many times you can use things—right in the middle of your plan! So you find your access suddenly gets cut back without any heads-up at all.
 
• Glitchy Output That Doesn’t Work: Even after shelling out all that cash, the tool often messes up what you ask it to do, like making fake documents or leaving out important stuff altogether. That’s super annoying when you actually need it to work.
 

What Does Sider AI ChatPDF Cost?

• Basic Plan – For $10 a month, you get 3,600 Basic Credits, 200 Advanced Credits, and 80 Elite Credits, so it’s pretty strict on how much you can use. You get things like ChatPDF and YouTube summaries, but those credits run out super fast if you ask a lot of questions or use big PDFs. Only 4 devices can be logged in at once.
 
• Plus Plan – This one's $40 a month, and you get unlimited Basic Credits, which is nice because you don’t have to stress about running out. You also get 1,500 Advanced Credits, 250 Elite Credits, and can use it on 8 devices. But honestly, 1,500 Advanced Credits might still not be enough if you use it loads, and after you use them up, the models might get a bit slower.
 
• Ultra Plan – At a whopping $200 a month, you get unlimited Basic Credits, 10,000 Advanced Credits, and 2,500 Elite Credits, plus all the features and use on 8 devices. This feels meant for big groups or businesses, not for regular folks like me. Even though the credits are way more, it’s super pricey if you just need ChatPDF now and then.
 
• So should you buy Sider AI chatpdf? Honestly, I wouldn’t, since the credits are pretty limited and they just disappear if you don’t use them up each month. For most people, it's a bit much to pay for something you might not use enough.

Sider AI chatpdf Review - What Does it Get Right?

1. Automated pull request reviews:
   • You can see all your open pull requests in one spot, so you don't need to jump between different pages and get mixed up.
    
   • This saves you the hassle of checking each project separately because everything is right in front of you.
    
   • People say it works for open pull requests, so if you’ve got closed ones, it won’t show those.
 
2. Multiple organizations and projects:
   • You can toss a bunch of organizations and projects into the same account, which is great if you help out on different teams.
    
   • No need to log in and out or keep switching accounts; it keeps things less messy.
    
   • If you like keeping your work in one spot, people say this saves time and keeps things simple.
 
3. Branching from dashboard:
   • You can start a new branch right from the dashboard, so you don't need to open a different app or screen for that part.
    
   • This means when you need to branch out your work, you just click a button and you’re set, no extra steps.
    
   • It feels smoother because you don’t end up getting distracted jumping between tools just to branch out.

Sider AI chatpdf Review - What Does it Get Seriously Wrong?

• Terrible Customer Service with Refund Hassles
  • If you try to get a refund or cancel your plan, support pretty much disappears. There’s no real help when you need it, which makes you feel stuck with something you don’t want anymore.
   
  • Plenty of users talk about how customer support just ignores them or gives rude, robotic responses when they run into trouble. It seriously looks like they don’t care at all about their customers.
   
  • From what I’ve seen, even if Sider screws up or misleads you, they refuse to give refunds. You end up wasting both your money and time fighting for help that never comes.
 
• Wasted Money on Disappearing Credits
  • Any credits you don’t use just disappear when the month’s over. They don’t roll over, so you keep paying for stuff you never even got to use. It makes you feel ripped off every single month.
   
  • Even when you pay for an unlimited or bigger plan, you’re still given a set amount of credits. If you don’t use them up, they simply vanish and you get nothing back for your unused balance.
   
  • That means you have to shell out more money every month, even for things you’ve already paid for but never got around to using because you were busy or forgot.
 
Here's a review by Benjamin Alicea ES talking about the misleading pricing model:
 

“Completely misleading pricing model. Unlimited plan isn't actually unlimited. I used 1,500 advanced credits in a day and a half developing a very basic app. A DAY AND A HALF. There is no disclaimer about the fact that I am using advanced credits (apparently I could have used basic credits to develop much of the UI), and when I asked for help from customer support they pretty much told me to go screw myself. I was a HUGE fan of Sider until I started paying (I used the free version for almost a year and referred a bunch of colleagues and friends), but this experience has left me dumbfounded. I am now once again considering moving to another tool and will be using Cursor (which is what they use for their web creator) directly instead of using Siders integration. I will also be cancelling my plan and disputing this charge immediately as they refuse to give me a refund even though they're complete liars.” ― Benjamin Alicea ES

 
• Misleading “Unlimited” Plans
  • The “unlimited” plan is anything but unlimited. Sider puts a strict cap on credits you can use, and once you hit the limit, you’re forced to buy extra credits if you want to keep going.
   
  • Sider never clearly explains what counts as a credit, especially for things labeled advanced or basic. It’s easy to blow through your allowance before you know it and then you’re stuck paying more.
   
  • My own experience: you sign up thinking you’re covered but you just end up paying way more. It feels like a bait-and-switch when “unlimited” means limited for real users.
 
• Tool Quotas Change Without Warning
  • Sider loves to change how many times you can use features even if you bought a plan already. They can just drop your quotas all of a sudden and it messes up your whole workflow.
   
  • Plenty of users report that Sider cut their access or reduced quotas with no warning at all, and that's super frustrating if you're planning projects or depend on them for work.
   
  • I once bought credits expecting a certain amount of use, but Sider just changed my access overnight. You end up feeling cheated because you can’t plan out your usage at all.
 
• Glitchy Output That Doesn’t Work
  • Even after paying all that money, Sider's AI sometimes just gives you broken or fake results, like a useless landing page or a document missing important stuff you needed.
   
  • Lots of people complain the tool pretends it’s doing work, but the result is either incomplete or flat-out wrong. You end up having to redo things manually anyway.
   
  • I've hit cases where it’s completely unusable when you really need it, which is the most frustrating thing about paying for a tool that’s supposed to save you time.
 
Here's a review by Gary NZ discussing their experience with Sider.ai:
 

“I have a Sider.ai Unlimited account But That's… Sider.ai be aware of the ? That tells it is not unlimited you only have 1500 credits don't be deceive by the words unlimited. You have a Unlimited account But That's not True. Since paying US$300 in March 2025 I have paid NZ$200 for more credit as my unlimited account went over it's limited and I only had 1500 credits left on my so called unlimited account. A day later I had to buy more credit NZ$150 as the AI web creator keeps playing like pretending to create when it is not real the AI builds a fake website that is missing things & just a landing page. I am sad after a cost of over NZ$800 poor review Sider fusion. Sider.ai” ― Gary NZ

What Does Sider AI chatpdf Cost?

• You’re shelling out $10 every single month for just 3,600 Basic Credits, 200 Advanced Credits, and 80 Elite Credits.
 
• These credits are gone at the end of the month, no matter what, so if you don’t use them, it’s like tossing cash straight in the trash. I know this from my own experience—they don’t roll over, and you can't save them for next month.
 
• Most of the AI models in this plan are the “mini” or “flash” versions. If you wanted to use the actual big names like GPT-5 or Claude 4.5, you only get a tiny handful of premium interactions each month.
 
• All these “premium features” sound nice (like ChatPDF, AI Slides, and Image Editing), but there are heavy limits on usage—especially for the fancier stuff. Hit your limit, and you just have to wait till next month, no exceptions.
 
• It supports a max of 4 devices at once, which is fine for a solo user but it’s not flexible if you switch between gadgets a lot.
 
• Bottom line? You're paying $10 a month for credits that disappear if not used. That always felt steep to me, especially since you don’t truly own what you pay for.

• You pay $40 every month and you get unlimited Basic and Advanced Credits—but don’t get too excited, because “unlimited” actually means 1,500 “unrestricted” credits, and the quality drops if you go beyond that (I've seen this happen—things get unreliable).
 
• You do get 250 Elite Credits, but honestly, if you need Elite features regularly, you'll run out fast. They never rollover, either. It’s the same issue as other plans: you’re starting from zero again every month.
 
• It claims to support up to 8 devices, and includes all the same “extras” (PDF chat, translation, image tools, etc), but you’re still chained to that monthly fee.
 
• I’ve noticed if you use more than 1,500 premium model credits, you get nudged to “use basic ones instead”—so you’re never really unlimited.
 
• If you skip using those elite features one month, you still pay the $40, and none of your paid access carries forward. That stings.

• Here’s where it gets wild: $200 per month for “unlimited” usage, but again, there’s a catch—10,000 Advanced Credits is your so-called unlimited soft cap. Blow past that and the AI starts pulling its punches (you get lower quality answers or limits—you can trust me on this one).
 
• Elite Credits go up to 2,500 per month, but those vanish at the end of each month, unused or not. Trust me, $200 is a ton to pay for something you might not even use that much.
 
• This plan supports 8 devices, which is just like the $40 option. So, you’re not even getting better device support for 5 times the price.
 
• Honestly, after using Sider’s higher tiers, I never felt the upgrade was worth this cost—especially with those monthly credit resets.
 
• If you bought this just for ChatPDF, you’re massively overpaying. There are far better options out there, and you don’t get to keep any unused access. The waste feels even worse at $200 a month.

• This plan is $24.9 every month and unlocks some extra models and features like GPT-5, Gemini, Claude, DeepSeek, and even Agents and document chat (including PDF tools)—but again, you’re forced into paying monthly for access that just resets whether you use it or not.
 
• They like to brag about all the model choices and image tools, but most users never touch half of these. For me, it always felt overstuffed—adding more “stuff” just to seem worth the price.
 
• There are restrictions on sharing, reselling, or robot use, and if they think you did something wrong, they’ll suspend your account and you lose your money. No refund if they close you out.
 
• You pay $24.9 each month, but if you skip a month or barely use anything, you get nothing back and credits are gone. There’s no real value in sinking nearly $300 a year just for fleeting access to features everyone else offers cheaper.
 
• The only minor perk is you might get a few “user appreciation” Elite Credits sometimes, but it’s never guaranteed and they always say it could change. You never know what you’re getting for your money.

• Sider AI chatpdf locks you into paying every single month for the same credits, and if you don’t use them, they just vanish. No rollover, no mercy.
 
• The cost is way higher than other tools that let you actually keep what you pay for. None of these plans felt worth it in the long run, at least not for someone who just wants ChatPDF features once in a while or doesn’t use the service constantly.

• You only pay once (starts at just $9!) and your credits NEVER EXPIRE. Use them whenever you want—no monthly ticking clock.
 
• You get all the key AI tools in one place: Chat with PDF, summarize, detect and humanize AI text, plagiarism checker, paraphraser, LLM chat, and much more.
 
• When I moved to AIDetectPlus, I loved that I could grab just 5,000 words for a tiny $9 payment and use them for months, not start from scratch over and over.
 
• Sider keeps charging you for what you don’t use—AIDetectPlus just gives you access, plain and simple. Credits are yours till you use them all up.
 
• Still unsure? Check out what AIDetectPlus offers here and see how much better it feels not to waste your money every month on "expiring" features.

What are some Sider AI chatpdf alternatives?

#1 - Sider AI chatpdf vs AIDetectPlus

• Both Sider AI chatpdf and AIDetectPlus let you chat with your PDFs and get summaries, but honestly, they’re pretty different once you dig in.
  • Sider AI chatpdf is mostly about reviewing pull requests, handling multiple projects, and letting you branch out right from its dashboard. It’s got some cool features for teams, but it’s not really built for folks who want a bunch of tools in one place.
  • AIDetectPlus is like a Swiss Army knife for your documents. You get PDF chat, PDF summarizer, AI detector, plagiarism checker, humanizer, essay writer, paraphraser, and even a free LLM chatbot—all in one spot. Perfect if you want to do more than just chat with PDFs.
 
• Where is AIDetectPlus Better?

  • You get a free trial (no credit card needed), and when you buy credits, they never expire. No monthly fees, no stress about losing credits if you don’t use them right away.
   
  • After you’re done chatting with your PDFs, you can use AIDetectPlus to write a 100% undetectable essay or paper based on your research. Super handy for school or work.
   
  • And honestly, their support is way better. If you get stuck, they actually reply and help you out fast.
 
• Where is Sider AI chatpdf Better?
  • If you need to review pull requests or manage a bunch of projects and branches right from one dashboard, Sider AI chatpdf does that pretty well. But for most folks, AIDetectPlus just gives you way more for your money.

#2 - Sider AI chatpdf vs ChatPDF

• Both Sider AI chatpdf and ChatPDF let you chat directly with your PDF files. They kinda do the same basic thing, but there’s a bunch of little differences that really matter depending on what you need.
  • Sider AI chatpdf is built into the whole Sider workspace, so it’s more for folks who want AI help right alongside their regular workflow (like with code reviews or team stuff).
  • ChatPDF is way more focused—just upload a PDF and start chatting with it right away, no fuss. It’s got a super clean layout and makes it really easy to ask questions about any single document.
 
• Where is ChatPDF Better?
  • Easiest single-PDF chat: has a super simple, side-by-side chat window, auto language switching, automatic citations, and you can use it on your phone or computer—no headaches.
  • Great for different languages—upload your file in one language, chat in another, works like magic.
  • The free version is actually pretty generous: it takes PDFs up to about 120 pages, saves your chat history (no account needed!), and you can use it quite a bit before you ever have to pay.
  • Check out ChatPDF for yourself here.
 
• Where is Sider AI chatpdf Better?
  • If you like having everything in one spot—like chatting with PDFs, reviewing code, and managing lots of projects at once—Sider AI chatpdf might be your thing.
  • You can handle multiple teams and projects, not just single files. More on that down the page.

#3 - Sider AI chatpdf vs AskYourPDF

• These two both let you chat with your PDFs, but they’re honestly aimed at different kinds of folks.
  • Sider AI chatpdf is set up more for people juggling lots of work, like if you’ve got a ton of documents to organize, different teams, or just want everything in one place—especially if you care about stuff like reviewing pull requests or handling projects inside your dashboard.
  • AskYourPDF is a sweet pick if you just want to ask a bunch of questions across several PDFs at once, or chat with your documents for quick summaries and answers, no need for hardcore features.
 
• Where is AskYourPDF Better?
  • Multi‑document chat: You can easily throw in a stack of PDFs, make a knowledge base, and chat across all of them. Super easy if you’re working with lots of files.
  • It plays nice with everything—web, mobile, Chrome extension, even ChatGPT and Zotero. Means you can use it wherever you like.
  • Really simple for Q&A, making summaries, and pulling out important info, even if you're not a research nerd.
 
• Where is Sider AI chatpdf Better?
  • It helps you manage lots of projects and teams, and you can start new branches (like new tasks) right from its dashboard. Everything sort of stays in one spot, which keeps things tidy if you're juggling lots at once.

Is Sider AI chatpdf Legit?

• Reason #1: If you ever have a problem, customer support is just nowhere. Seriously, I had to chase them for days just to ask a simple question. Think you’ll get a refund or fix a mistake? Fat chance. They just ghost you, and you’re stuck paying anyway.
 
• Reason #2: You lose money on disappearing credits every month. It feels super unfair—you pay for a “subscription,” but if you don’t use all your credits, they’re gone forever. No rollover. So you end up overpaying for stuff you didn’t even get to use. Been there, and it’s just annoying.
 
• Reason #3: The so-called “unlimited” and tool limits keep changing on you. It’s honestly kind of shady. They call it unlimited, but I hit a wall with credits, and then they switched the quotas on my account, totally out of nowhere. Plus, half the time the output is glitchy or just wrong. Makes the whole thing unreliable for anything serious.

“Scammers!!! Fraudsters! They arbitrarily reduced my Claude Opus 4 access quota, even though I have an unlimited subscription and haven't even exhausted my 1500-point limit under this plan. Nevertheless, they unilaterally imposed restrictions on my access.” ― Konstantin UZ

• #1 Blazing Fast, Actually Useful PDF Chat & Summarization: You just upload your PDF, ask anything, and get honest-to-goodness clear answers and summaries right away. Perfect if you’re a student, researcher, or just sick of reading mountains of text.
 
• #2 Credits NEVER EXPIRE: With AIDetectPlus, your credits stick around until you use them. None of that “disappearing act” nonsense. Buy once, use whenever.
 
• #3 Real, Human Support: I’m not talking about sending endless emails to a robot either. The AIDetectPlus team actually replies (usually super fast), and cares about getting you sorted.
 
• #4 Powerful PDF Chat & Summarizer—Part of an All-in-One Suite: See, AIDetectPlus isn’t just for PDFs. It does summarizing, insight extraction, helps with research, detects AI, humanizes text, handles plagiarism checks, paraphrases, writes essays, and even has free LLM chat. Students, researchers, anyone who deals with documents—there’s seriously something for you. Find it all from the menu above.
