See the process while it happens.

About every 25 words, Borzoi classifies the writing pattern locally. No upload. No waiting for a final draft.

TranscriptionLooks like text is being followed closely from somewhere else.
CompositionLooks like the writer is generating the language as they type.
ParaphraseLooks like existing language is being rewritten in new wording.

Generated text does not have to be pasted. It can be retyped, or rewritten until a final-text detector has much less to go on.

In my younger and more vulnerable years my father gave me some advice that I’ve been turning over in my mind ever since. “Whenever you feel like criticizing any one,” he told me, “just remember that all the people in this world haven’t had the advantages that you’ve had.”

Zoom out. See the whole draft.

Analyze turns the session into a passage-by-passage process map, with writer continuity alongside it.

AI detectors look at the answer. Borzoi looks at the work.

A final draft can be polished, retyped, or rewritten. The process is harder to fake accidentally.

Final-text AI detector

Judges what remains.
SEESThe finished document.
CAN ANSWERDoes the finished prose resemble generated writing?
MISSESWhether generated text was retyped, rewritten, or entered by someone else.

Revision history

Shows what changed.
SEESSaved changes, timestamps, revisions, and paste events.
CAN ANSWERWhat changed, and when?
MISSESThe behavioral difference between composing, retyping, and rewriting.

Analyzes how it was produced.
SEESKeystroke-derived behavior while language is being produced.
CAN ANSWERDoes this look composed, transcribed, or paraphrased — and does the writer remain consistent?
REVIEWER GETSProcess map, writer continuity, and a signed portable proof.

Borzoi reports behavioral evidence, not a verdict that AI was used.

Keep the proof with the work.

Private while you write. Reviewable when you choose.
