About Promptler

Promptler is a private, on-device prompt workspace for iPhone and iPad — a place to save, organize, and reuse the AI prompts that actually work for you, alongside whatever AI tools you already use.

Who's behind it

Promptler is built by Francisco Martinez, the founder and a former software engineer at LinkedIn. After years of watching good prompts get lost in chat history and scattered notes, he built the tool he wanted: a fast, private library for the prompts you return to — no account, no cloud lock-in, everything on your device.

What we believe

Your prompts are yours. Promptler is bring-your-own-AI — it works alongside ChatGPT, Claude, Gemini, Perplexity, Copilot, and local models without ever needing to see your conversations. Everything stays on-device by default, you can export your whole library as JSON anytime, and the guides we publish are written to be genuinely useful whether or not you ever install the app.

The guides

We write practical, evergreen guides for people who use AI every day. Start with all Promptler guides, or get the app and save your first 15 prompts free.
