Your saved prompts,
one click away.
A personal prompt library that lives inside ChatGPT, Claude, DeepSeek, and Kimi. Built for engineers and AI power users who are tired of retyping the same instructions every session.
See it in action.
Install, setup, and a real session showing how PromptMate fits into a daily AI workflow.
Works where you work.
Opens as a sidebar on ChatGPT, Claude, DeepSeek, and Kimi. No context switching, no separate tab.
One-click open on ChatGPT
The PromptMate button appears in the bottom-right corner.
Sidebar with tone & format
Search, pick tone, pick format, click Use. Done.
Same experience on Claude
Same sidebar, same library, both interfaces.
Insert with full context
Tone and format instructions are appended automatically.
The friction was real.
I use Claude and ChatGPT for almost everything now: code reviews, draft emails, explaining concepts to teammates, writing scripts for YouTube. And I kept typing the same instructions over and over.
Not the prompts themselves — I had those saved in Notion, in a text file, scattered in browser tabs. The problem was the ritual: open a new chat, remember which prompt, find the file, copy, paste, adjust the tone manually. Every. Single. Session.
I wanted the prompts where the work happens. Not in a tab I have to switch to. In the sidebar, with one click to insert. So I built it.

This is what's shipped. Not what's planned — that's the roadmap below.
Sidebar inside ChatGPT, Claude, DeepSeek, and Kimi
No tab switching. Your prompts live where you work — a sidebar that opens on ChatGPT, Claude, DeepSeek, and Kimi with one click.
Save with tone and format
Each prompt stores a tone (formal, casual, technical) and output format (bullets, steps, prose, code). Inserted together, in one click.
Open source, no backend
Syncs to your own private Google Drive folder. No data on my infrastructure. You own your library.
Edit on demand
Prompts aren't locked. Open any saved prompt, tweak it mid-session, save back. The edit is yours.
Local usage analytics
Tracks how often you create, apply, copy, and delete prompts. Stored locally so you can see what's actually useful.
Prompt history
Every prompt you use is logged. Go back to any previous prompt from your session history — nothing gets lost between chats.
What's next.
Three features in active design. If any of these matter to you, raise an issue or vote via the feature request form.
Group Prompts
Organize your library into named groups — by project, by use case, or by workflow. Find what you need without scrolling through everything.
Share Prompts
Publish a prompt to anyone-with-link. The receiver gets their own copy. Private by default, shareable on demand.
Codex & Claude Code desktop
Bring your prompt library into Codex and the Claude Code desktop app — the same one-click insert experience, now for coding workflows too.
Prompt version history
Every edit to a saved prompt creates a version. Browse the history, see what changed, and restore any prior version without losing work.
Stop retyping. Build your library once.
Install PromptMate, save the prompts you actually use, and get them back in one click — in ChatGPT, Claude, DeepSeek, or Kimi, on any device.
