Understanding for writers
Bring your essays, posts, notes, and journals. Corpus reads across them to reveal the through-lines, open questions, changing beliefs, and contradictions already there.
Most AI starts with an empty prompt.
Corpus starts with your history.
Topics are easy. A through-line is an argument you have been making, revising, and resisting for years.
It reads. It never writes.One corpus, read together
How it reads
No prompt engineering. No blank chat box. Corpus works from the record you have already made.
Upload essays and notes, import a public Substack, or paste loose writing. Each piece stays intact, dated, and traceable to its source.
Corpus finds recurring themes and entities, then reconciles them across years of work. A claim only survives if it resolves to the passage that supports it.
Through-lines become chronological spines. Questions branch away. Answers rejoin. Contradictions fork the line until you decide what changed.
What it finds
Not “you write about attention.” Corpus surfaces the deeper claim that keeps surviving every version of the work, then shows which pieces carry it.
A strong setup that never gets paid off is not lost. Corpus keeps it attached to the piece that raised it, ready for you to revisit or let go.
Two incompatible positions can be a mistake, a genuine evolution, or a tension worth keeping. Corpus holds both passages open. You decide.
No floating summaries. Every theme, thread, drift, and contradiction opens back to the exact source span that earned it a place.
Built on restraint
No drafting, rewriting, or synthetic imitation of your voice. Corpus reads the work. The sentences remain yours.
Every surfaced idea carries its source passage. If the span cannot be verified, the claim does not ship.
A contradiction is evidence, not a verdict. Accept it, mark an evolution, or reject the finding.
Private by default, never used for training, and hard-deleted with your account when you ask.
