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
Build lasting comprehension of any text. Reading becomes a conversation — for people who don't just consume information, they converse with it.
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.
