Offline-first prompt capture

Write before you code.

Prologue catches a prompt the moment it lands — mid-run, mid-meeting, fully offline — scores it, and hands it to your agents the second you sit back down.

The loop

Your best prompts arrive when you can't type them.

Prologue is the notebook between the idea and the terminal — three stages, in order.

01 · CAPTURE

Get it out of your head

Text, continuous voice dictation, or the home-screen widget. Capture never touches the network and never judges the writing — it just takes the prompt, up to 10,000 characters, and holds it.

02 · SYNC

It lands in your backend

Cues sync to a Postgres row that belongs to you, isolated by row-level security. Sign in once with an email link; everything captured offline reconciles when you're back online.

03 · ACT

Dispatch from your terminal

The MCP server puts your queue inside Claude Code: list what's pending, dispatch a cue as the working prompt, write the outcome back. Your prompting gets a score — and a trend.

Connect

It plugs into your systems, not the other way round.

Claude Code, via MCP

Register prologue-mcp once and every session can see your queue.

Your dashboard

The queue is a Postgres table — wire it into whatever you already look at every morning. A ready-made panel ships for Next.js dashboards.

Your data, literally yours

Cues live in your own Supabase project. Export, query, or point other tools at it — there's no walled garden to leave.

}

How the free limit works: past 1,000 notes, your oldest notes are deleted to make room for new ones. Capture never stops — but your history does. Pro keeps every prompt you've ever written.
