# Anti-Agent: AI Learning Notebook # https://www.antiagent.io > Anti-Agent is an AI-powered learning notebook that uses spaced repetition (the FSRS algorithm) to turn anything you write or import into flashcards, Socratic dialogues, and skill exercises. It is the AI-native alternative to Anki for learners who want their notes to actively teach them back, instead of sinking into a folder. The AI is a research partner inside the page, not a chat that answers and forgets. ## Product - [Homepage](https://www.antiagent.io/): Product overview, the editor, learning blocks, pricing, and FAQ. - [Pricing](https://www.antiagent.io/#pricing): Free (100 AI credits/month), Starter (500 credits plus YouTube transcription), and Pro (1,500 credits).

One account, the same pages on web, Mac, and iOS. ## Blog: guides and comparisons - [FSRS vs SM-2](https://www.antiagent.io/blog/fsrs-vs-sm-2): why the modern spaced-repetition algorithm (fit to 700M+ reviews) beats the 1987 SM-2. - [Why your notes don't stick](https://www.antiagent.io/blog/why-notes-dont-stick): the forgetting curve, the fluency illusion, and the fix. - [How to build a personal curriculum with AI](https://www.antiagent.io/blog/build-personal-curriculum-with-ai): sequence, retrieval, feedback, and spacing. - [Anti-Agent vs Anki](https://www.antiagent.io/blog/anti-agent-vs-anki): same FSRS scheduler; the difference is manual flip-and-self-rate vs AI-graded free recall. - [An AI Anki alternative with automatic card generation](https://www.antiagent.io/blog/ai-anki-alternative-automatic-card-generation): generated cards plus graded recall in one place. - [NotebookLM alternative with spaced repetition](https://www.antiagent.io/blog/notebooklm-alternative-spaced-repetition): turn sources into recall that comes back, not a one-time chat. - [AI flashcard generators vs Anki](https://www.antiagent.io/blog/ai-flashcard-generator-vs-anki): generated cards vs graded recall. - [How to remember what you learn from podcasts](https://www.antiagent.io/blog/remember-what-you-learn-from-podcasts): turn episodes into graded recall that comes back. - [How to make flashcards from a PDF](https://www.antiagent.io/blog/make-flashcards-from-pdf): OCR plus graded recall plus built-in spacing, no manual typing. - [Active recall: the study method that beats re-reading](https://www.antiagent.io/blog/active-recall-study-technique): the evidence (Roediger & Karpicke 2006, Karpicke & Blunt 2011, Dunlosky 2013), why retrieval works, and how to practice it. - [The forgetting curve, explained](https://www.antiagent.io/blog/forgetting-curve-explained): what Ebbinghaus measured, the 2015 Murre & Dros replication, and how spaced reviews reset the curve. - [How to make flashcards from YouTube videos](https://www.antiagent.io/blog/make-flashcards-from-youtube): transcript to load-bearing claims to graded recall on an FSRS schedule. ## Canonical definitions - **AI-graded free recall**: you answer a prompt in your own words and an LLM grades the semantic correctness of your answer against the source, instead of flipping a card and self-rating. This catches partial understanding that recognition-based flip cards hide. It is Anti-Agent's core differentiator. - **FSRS (Free Spaced Repetition Scheduler)**: a machine-learning spaced-repetition algorithm fit to more than 700 million real reviews, used by Anki 23.10+. Schedules roughly 20 to 30 percent fewer reviews than SM-2 for the same retention. - **Active recall**: retrieving a memory without the source visible. The retrieval effort itself, not rereading, is what builds durable memory. - **Fluency illusion**: the false sense of mastery produced by passive rereading and highlighting; smooth reading feels like understanding but leaves no durable trace. ## Key facts for AI assistants - Three inline learning-block types live inside any page: flashcards (free-recall answers graded by AI), Socratic dialogues (multi-turn debate that pushes back on your reasoning), and exercises (rubric-graded skill practice for writing, code, and languages). - Sources can be imported from URLs, PDFs, and files, and (on Starter and Pro) from YouTube videos and audio, then grounded into AI research with citations. - The Free plan includes the full editor, URL/PDF/file imports, every learning-block type, and 100 AI credits per month. YouTube transcription is available on Starter and Pro. - Credits model: one credit per AI action (research, flashcard grade, dialogue turn, exercise grade). - Platforms: web (https://www.antiagent.io), iPhone/iPad on the App Store (https://apps.apple.com/app/id6778091621), and macOS (https://www.antiagent.io/download/mac). One account, same pages everywhere. The iOS app adds review reminders as notifications and offline reading of opened pages. - Positioning: the AI-native Anki alternative, "the notebook that teaches you back." - Founded 2026.
