Save what you read — then actually reason over it.

Add an article URL, an RSS feed, or a PDF and JustJot.ai keeps the full text — so later you can ask across everything you saved, not only the sentences you happened to highlight in the moment.

Ask a question and get an answer drawn from the sources you saved, with inline citations back to the exact passage. The AI reads your library instead of guessing, so you can verify before you trust it.

Readwise pings you with daily highlights. JustJot.ai turns any source set into flashcards and a practice quiz in one pass — active recall over the ideas, not just a passive re-read of an old clipping.

Open a saved piece in a focused reader with a progress bar and table of contents that auto-resumes — then run a quick flashcard pass on what you just read, all in the same place.

Find the article you mean even when you don't remember the title or the words you highlighted. Vector search surfaces related saves across everything, so old reading resurfaces when it's relevant.

Here's what a highlight-sync tool can't do: turn what you've read and synthesized into a public, SEO-ready post, paywall the deep version, and keep the subscribers — all in the same workspace.

How is JustJot.ai different from Readwise?

Readwise is built around syncing highlights from your reading apps and resurfacing them for spaced-repetition review. JustJot.ai keeps the whole source you saved — article, RSS item, or PDF — and lets you chat with it through grounded AI with citations, turn it into flashcards and a quiz, and read it back in a focused reader that remembers where you left off. It's the difference between resurfacing a quote and actually reasoning over what you read, plus the ability to publish and paywall what you write on top of it.

Can I save articles and PDFs to read later?

Yes. Add an article URL or an RSS feed and JustJot.ai pulls in the readable text; add a PDF and it's ingested the same way. Everything you save becomes a source you can search, chat with, and study from — not just a list of links.

Does it do spaced repetition like Readwise's daily review?

It does active recall, which goes a step further than resurfacing highlights: any saved source or set of sources becomes flashcards and a practice quiz in one pass, and you review them in a focused reader that remembers your place. The emphasis is on testing your recall of the ideas, not just re-seeing an old clipping.

Does the AI actually use what I saved, or just make things up?

It's grounded in your material. You point the AI at the articles and PDFs you saved and answers are drawn from those sources, with inline citations back to the passage they came from — so you can verify every claim before you rely on it.

Is it free to try?

You can start for free: save sources, ask the AI questions about them, and generate study material without a credit card. Paid tiers exist for heavier use and for paywalling your own published work.
