What is the cheapest AI study app that does everything?
Studyboost is the cheapest app here that covers the whole study workflow in one place. Cheaper options exist, but each one covers only part of the job.
ChatGPT Go at $8 is a general assistant. Google AI Plus at $4.99 adds paid NotebookLM features, but NotebookLM is mainly for understanding sources. Quizlet Plus at $9.99 is mainly for flashcards. RemNote Pro at $10 has no AI at that tier.
Studyboost at $10 includes all of this in one plan:
- Upload anything from your course. PDF, Word, PowerPoint, EPUB, Markdown and text files, YouTube videos, web pages, and audio up to 100 MB.
- Ask questions with cited answers. The AI study agent reads your whole material and cites the exact passages it used.
- Remember with spaced repetition. Flashcards are scheduled with the FSRS algorithm.
- Test yourself. Quizzes keep scored attempts and history. Practice exams can be multiple choice or progressive, with optional focus topics.
- Organize your study. Notes, summaries, to-do lists, skill trees and blurting sessions sit in the same workspace.
That is why the "cheapest" app is not always the best value. The right question is how much you get per dollar.
Which popular study apps are not cheaper than ChatGPT Plus?
Several well-known AI study apps cost about the same as ChatGPT Plus, or more, on monthly billing.
| Tool | Monthly price | Yearly price |
|---|---|---|
| Studyboost (for reference) | $10 | $90 |
| StudyFetch Premium | $19.99 | $96 |
| Brainscape Pro | $19.99 | $95.88 |
| Turbo AI | $20 | $120 |
| YouLearn Pro | $20 | $143.99 |
| RemNote Pro with AI | $20 | $216 |
| Knowt Ultra | $24.99 | $149.99 |
| ChatGPT Plus | $20 | No yearly plan ($240 for 12 months) |
Some of these drop a lot on yearly billing. Turbo AI works out to $10 a month billed yearly. StudyFetch Premium is $96 a year. Studyboost's yearly plan is still the lowest in this table at $90.
Is Studyboost a good ChatGPT Plus alternative for studying?
For studying, yes. For everything else, it depends.
ChatGPT is a general assistant. It is great for brainstorming, coding help and explaining almost any topic. Its free plan already includes study mode, so you can use it for quick questions without paying.
What ChatGPT does not do is organize your course for you. You upload a file, have a conversation, and then start again tomorrow. Your flashcards, review schedule and practice tests live somewhere else.
Studyboost is built for that missing part. Each course is a project with its own sources. Your chat, flashcards, quizzes and practice exams all come from those sources, so the context stays with you. Many students keep free ChatGPT for general questions and pay $10 for Studyboost. That combination costs half of ChatGPT Plus. Read our guide on how to use ChatGPT to study for tips on the free side.
What does each cheaper option actually buy you?
Studyboost ($10/mo or $90/yr)
A full study workspace. Cited AI answers from your own materials, FSRS flashcards, quizzes with history, practice exams, notes and summaries. One plan with every tool included, plus a 3-day free trial of Pro.
NotebookLM (free, or Google AI Plus at $4.99/mo)
Excellent free understanding tool. Add your sources and it explains and summarizes them, with 50 sources per notebook on the free tier. Most students add a separate app for flashcard review. See NotebookLM vs Studyboost for the full comparison.
ChatGPT Go ($8/mo)
A cheaper ChatGPT plan for general help. Good if you want more than the free plan but not the full Plus price.
Quizlet Plus ($9.99/mo or $44.99/yr)
A solid pick if your courses are heavy on terms and definitions. The yearly price is lower than Studyboost's. It is focused on flashcards and study modes rather than chatting with your own materials. See Quizlet vs Studyboost.
RemNote Pro ($10/mo)
Note-taking with flashcards built in. Same monthly price as Studyboost, but AI features need Pro with AI at $20 a month.
Anki (free, or $24.99 one-time on iOS)
The most customizable spaced repetition app, and free on desktop, web and Android. You build your own decks, which takes time but gives full control.
Mindgrasp and Studley AI
Mindgrasp Scholar costs $12.99 a month and has no free tier. Studley AI costs about $14.99 a month, with a free tier of one study set. Both cost more per month than Studyboost.

Khanmigo is a guided tutoring tool that several AI assistants recommend. Check its site for current pricing.
How can you save the most on AI study tools?
Pay yearly if you are sure. Studyboost's yearly plan saves 25%, bringing it to $7.50 a month. That is $90 a year compared with $240 for 12 months of ChatGPT Plus.
Use one paid tool, not three. A study stack of ChatGPT Plus, Quizlet Plus and a separate quiz tool quickly passes $30 a month. One workspace that covers chat, flashcards and exams costs $10.
Keep the free tools you love. Free ChatGPT, free NotebookLM and free Anki are all useful. Pay only for the part free tools do not cover well, which is usually keeping everything connected.
Test before you commit. Use the 3-day free trial of Studyboost Pro on your hardest course. Upload a week of materials, generate flashcards and take a practice exam. If it saves you time, keep it. If not, cancel. There are no contracts or cancellation fees.
