Big prompts deserve better than a one-line box

Everything got a modern editor except the terminal — the place developers actually live. Quill fixes that: compose prompts in real Markdown, preview the structure live, and send — to your AI coding CLI or straight to the API. Nothing rewritten, nothing lost.

You've felt this

Six requirements, one wrapping line, arrow keys to edit the middle — and then Enter fires before you're done.

any AI cli — one-line input

Welcome back. Type a prompt:

Ctrl+Enter sends when you say so.

Try it on a real blob

Paste any run-on prompt — or use ours — and see what structure does to it. This is the difference Quill makes before your model ever reads a word.

Built for how you already work

You already use an AI coding CLI

Keep your coding agent open in one tab. Open Quill in a second for the prompts that need more thought.

Your CLI handles the coding. Quill fills the gap it leaves: structured thinking, architecture reviews, research prompts, specs — composed properly, then handed to the same CLI you already run. Zero habit change.

You live in the terminal

Stop writing important prompts in a single-line box.

vim, tmux, git — and then a browser tab for AI? Quill keeps the whole loop in the terminal: a real editor with live Markdown preview, history, templates, and keyboard-first everything.

You engineer prompts for a living

Your prompts are documents. Treat them like documents.

Prompts as first-class .md files — version-controlled, diff-able, reusable as templates, searchable in history. Drafting in a notes app and pasting into a chat box was never the workflow.

Live Markdown preview

See the structure as you type — side by side.

Send anywhere

AI coding CLIs, Anthropic & OpenAI APIs, or your shell.

Skills popup

Type / and your CLI's real commands autocomplete.

Templates & history

Every sent prompt saved and searchable, locally.

Keys in the OS keychain

Never in files, never in logs, never in prompts.

Dark & light themes

The same two you're looking at right now.
