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.
iOS beta · your data in your own Postgres row · MCP-nativeYour best prompts arrive when you can't type them.
Prologue is the notebook between the idea and the terminal — three stages, in order.
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.
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.
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.
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.
// ~/.claude.json — one block, once "prologue": { "command": "node", "args": ["…/prologue-mcp/dist/index.js"], "env": { "PROLOGUE_OWNER_ID": "you" } } // then, in any session ❯ what's in my prologue queue? ⏺ list_pending_cues → your phone, answering
Set up in an evening.
Three short guides take you from install to a connected system — read the docs.
