Prompts are code.Treat them like it.
Version, diff, and ship your LLM prompts the same way you manage your codebase. Git-native prompt management, directly in your IDE.
$ quill commit "Update system prompt v2"
✓ Committed prompt: system-prompt.yaml
+ 3 lines, − 1 line (est. −12% tokens)
See Quill in action
Three commands. One source of truth for your whole team.
Everything your prompts deserve
The same discipline that made your codebase reliable — applied to your LLM prompts.
Git-Native Versioning
Every prompt change is a commit. Full history, instant rollback. Works with your existing Git remote.
IDE Plugin
VS Code + JetBrains extensions. Manage prompts without leaving your editor. Zero workflow change.
Team Sync
One source of truth across your team. No more Slack threads or outdated Notion docs.
Token Cost Delta
See estimated token impact on every diff. Identify and eliminate prompt bloat before it ships.
Diff View
Readable prompt diffs like code diffs. Review, comment, approve — just like a PR.
Audit Trail
Complete change history. Know who changed what, when, and why. SOC2-ready logging.
From chaos to clarity in three commands
No new infrastructure. No context-switching. Quill works inside your existing workflow.
Install the extension
One command. Works with VS Code and JetBrains IDEs. Prompts are stored as `.yaml` files tracked in your repo — no new services to run.
$ code --install-extension quill.quill-vscode
Installing Quill... ✓ Done
Commit prompts like code
Write your LLM prompts as structured files. `quill commit` versions them alongside your codebase. Git history, blame, and PRs all work out of the box.
$ quill commit "Tighten system prompt"
✓ Committed: system-prompt.yaml
Token delta: −18% (est.)
Ship a single source of truth
Your team pulls the latest prompts the same way they pull code. No more 'which version are you on?' — everyone runs the same prompt, every time.
$ quill sync
✓ Pulled: 3 prompts updated
✓ Team is on v2.4.1
Stop managing prompts like sticky notes
Every LLM-building team is re-inventing the same broken workflow. Quill replaces it.

Git blame for prompts. I didn't know I needed this until I had it.
