Synthesis
As you mark chapters understood, Intralocutor weaves notes, highlights, and discussion into a cumulative synthesis you can revise and expand.
Intralocutor
Read deeply · Think clearly
Reading becomes a conversation.
Build lasting comprehension of any text — for people who don't just consume information, they converse with it. Bring your own books: upload any EPUB or PDF and start the discussion.
Features
Everything you need to think alongside what you read.
An AI discussion partner
Argue, question, and think out loud with a partner that understands the book. Every reply is grounded in the page in front of you.
Multi-read-through notes
Return to a text across years and keep every pass in one place. This winter's margin note still talks to the one you left three reads ago.
Highlights & margin notes
Mark the lines that matter and leave notes in the margin. Your capture stays attached to the page — ready when you come back to the argument.
Grounded citations
Claims point back to the passage they came from. No floating summaries — you can always open the source and check the text yourself.
Understanding
Synthesis, concept graphs, and thematic extraction.
Reading is only the start. Intralocutor turns what you marked, noted, and discussed into a living map of the book — so comprehension compounds instead of fading.
Concept graphs
Ideas surface as a map you can walk: themes, claims, and relationships extracted from what you actually read — not a generic outline of the book.
Thematic extraction
Recurring threads and tensions are pulled out of the text so you can see the shape of an argument before it blurs into a pile of highlights.

Questions
Asked, answered.
Where do the books come from?
You bring them. Upload any EPUB or PDF from your own shelves, or fetch a public-domain classic from inside the app — either way the full text is there to read, mark, and discuss. For books that only exist on paper, you can capture passages by photo and discuss those.
Which AI carries the discussion?
Language models hosted on Groq, chosen for speed and candor. Every reply is grounded in the passage in front of you and cites the lines it drew on, so you can always open the source and check. If you keep your own API key, you can bring it.
Are my notes and highlights private?
Yes. Your library, notes, and discussions belong to your account alone. Nothing is visible to anyone else unless you create a share link, and you decide what a link shows. You can also export your notes to Markdown whenever you like.
What happens when the 7-day trial ends?
Nothing dramatic. Every new account begins with seven days of Bookworm — no card required. When the week is up you keep the Free tier, and everything you have read and written stays where you left it. Upgrade only if you find you miss what the trial showed you.
Can I cancel anytime?
Yes. Manage your subscription from your account page — cancel in a click and your plan simply returns to Free. Your books and notes remain yours.
