Most teams keep their best AI prompts in the worst possible places — a Notion page, a Slack DM, a note on someone's desktop. The prompt that actually worked gets lost, rewritten slightly worse, and rewritten again by the next person.
Promptalyst is a private prompt library that fixes that. It gives a team one place to save, organise, version, share and run the prompts they depend on.
Variables. Write a prompt once with {{placeholders}} for the parts that change — brand, product, audience — and Promptalyst turns them into a form. No more copying a template and hand-editing six brackets, and no more shipping copy addressed.
Version history. Every edit is saved automatically. See exactly what changed between two versions, and restore an earlier one when a well-meaning tweak makes the output worse. Prompts degrade quietly through small edits; this is how you catch it.
Bring your own keys. Promptalyst runs prompts on OpenAI, Anthropic, Google, Mistral, Groq and xAI using your own API keys, stored encrypted and never sent to the browser. You pay the provider directly — there is no per-token markup — and you can switch model per prompt without rewriting anything.
Built for teams. Workspaces with owner, editor and viewer roles. Agencies run a separate workspace per client, which makes brand bleed structurally impossible rather than a matter of discipline, plus one internal workspace of house templates.
Also: folders and tags, full-text search, a Cmd+K command palette, import and export as JSON or CSV so you are never locked in, run counts and analytics so you can see which prompts are actually earning their place, and a public marketplace for buying and selling prompt packs.
It works offline. Promptalyst is an installable PWA with a local cache, so you can read and edit your library with no connection and changes sync when you reconnect.
Free forever for 20 prompts, one member and five runs a day — no card required. Paid plans start at $12/month.
