The prompt manager that doesn't need your email address. Tag, template, and test your prompts — stored locally, under your control, completely free.
The prompt that tripled your output last month? Three archived chats deep. The template you spent a week refining? Gone when you switched tools. Sound familiar?
Your best prompts live in old conversations you'll never scroll back to. Every great result you can't replicate is time and money left behind.
You change the tone, the audience, the length — and retype the whole structure every single time. You don't have a creativity problem. You have a storage problem.
You looked at cloud prompt managers. Then you read their terms of service. Your prompts are your competitive edge — handing them to a stranger's server is optional.
Six features, zero bloat. Built for the moment you're mid-workflow and need the right prompt in under three seconds.
Drop {{variables}} anywhere in your prompt. They're auto-detected and turned into a live form you can fill and preview before you copy anything.
Three top-level categories — Writing, Coding, Marketing — plus unlimited free-form tags. Filter by multiple tags at once. Find anything instantly.
Writing · Coding · MarketingFill your variables and watch the prompt compile in real time. Filled values appear in green, missing ones flagged in red. One click copies the finished output.
Fill → Preview → CopySearches titles, content, tags, and categories at once. Hit ⌘K from anywhere. Results are instant — because everything is local.
Star your highest-performing prompts. A dedicated view keeps them front and centre. Sort by favorites so your best work is always one click away.
Stored in localStorage. Nothing leaves your machine. No account, no sync server, no telemetry. Save the HTML file and it works fully offline — no internet required. Your prompts are your competitive advantage. They stay that way.
No onboarding. No tutorial. Open the app and your first prompt is ten seconds away.
⌘N opens the editor. Paste or write your prompt, pick a category, add tags. ⌘+Enter saves. Done in ten seconds.
Replace specifics with {{variables}}. Quick-insert chips handle the common ones — {{tone}}, {{topic}}, {{audience}}. Every variable auto-detected as you type.
Open the test panel, fill your variables, watch the output compile live. One click copies to clipboard — ready for Claude, ChatGPT, or whatever you're running.
Every cloud-based prompt manager stores your work on their servers. The ones that don't usually cost money. PromptVault costs neither.

localStorage. That's it — nothing leaves your machine, nothing is transmitted, nothing is logged. If you clear your browser data, your prompts go with it, so back up the localStorage key before you do.promptvault.v1 → copy the value. Paste it back in the same key on another browser or machine to restore. A proper export button is on the roadmap.PromptVault is a free tool. The bigger work is on the other side — AI cold callers that book meetings, content pipelines that run without you, voice agents that qualify leads overnight, custom n8n workflows that replace three tools you're currently paying for. I build those for teams who are done duct-taping.
Free. Local. One HTML file. No install, no account, no nonsense.
