AntiAgent

AntiAgent is a web-based learning tool that combines a document editor, an AI writing assistant, and a spaced-repetition scheduler. It is for people who want to study a subject or build a skill while keeping the cognitive work their own. Its premise is that learning should sharpen the user's own thinking rather than delegate it, summarized as "Learning for humans. In the age of machine learning."

How it works

The unit of work is a page: an editable document on a chosen subject or skill. Pages are written in a block editor that supports formatting, drag-to-reorder, and a slash menu.

Material can be imported from URLs, PDFs, YouTube, audio, and prior pages. An embedded agent can, on request, stream a researched and cited section directly into the page.

The three review modes

Once a page exists, it generates three recurring review activities:

• Memory: typed-answer flashcards that the AI grades in plain language.
• Thinking: Socratic dialogues, with modes to debate, rehearse, converse, or explain, and adjustable difficulty.
• Skill: rubric-based exercises graded by the agent, where the rubric is written in the page itself.

These activities are not reviewed on a fixed cadence. Timing is set by the FSRS spaced-repetition algorithm, which schedules the next return for the day estimated retention is most at risk.

Pages can be published publicly in one click and forked by others; the creator keeps ownership and progress.
