AI Tools

A small set of focused, browser-based tools. Preview Markdown as you write it, turn a prompt template into a form you fill in and copy, or research a niche and build a sellable PDF with AI. No install, and the two client-side tools don't even need an account.

A couple of these run heavier jobs on our backend and ask for your own Anthropic, OpenAI, or OpenRouter key. Those are marked below. Runs bill against your key, and nothing you paste is stored or logged.
