Free with sign-up · Rate-limited on the free tier

A journal that never rewrites itself.

Every account gets an Optimus journal — a private, running record that works like a ship's log: entries are only ever added, never edited or quietly replaced. If something turns out to be wrong, a new entry corrects it on top, and the whole trail stays visible, in order, forever.

What you get

Write. Elle responds. Nothing disappears.

01 · APPEND-ONLY

Your permanent record

Start threads on anything you're working through. Every entry is stamped in order and kept forever — the same discipline a lab notebook follows.

02 · ELLE IN THE MARGINS

Ask her to respond

On any thread, ask Elle to read what's on the record and write back. Her entries land in the same append-only trail as yours.

03 · THE PHASE STATE

Watch the thinking move

Each entry carries a coherence reading (κ) — a simple signal for whether a line of thought is getting steadier or drifting, tracked like a fever chart over time.
