A Notion-based operating system for building, organizing and monetizing Custom GPTs
Keeps tutorials, use cases and templates organized so you can reuse your best resources instead of starting from scratch every time.
A dedicated space to generate, capture and revisit Custom GPT ideas so promising concepts never get lost in scattered notes.
A structured build pipeline plus version tracking so you can iterate on a GPT and safely roll back or compare earlier versions.
One central view that lists and manages every active GPT you run, removing the need to hunt through separate tools or bookmarks.
One API key for agent-grade web search, fetch, browsing and automation
Real browser-rendered search that returns structured JSON with fresh, uncached results from the live web, with no search fee.
Convert any URL into token-efficient Markdown, JSON or HTML, stripping navigation bars, cookie banners and ads before they reach your model.
Full cloud browser sessions with persistent state that you drive with Playwright, Puppeteer or the Chrome DevTools Protocol.
Give an agent a goal in plain English and it navigates, fills forms and returns structured results; monitoring fires alerts when a tracked page or topic changes.
Features a massive marketplace of ready-to-run scrapers, though it operates more as an actor platform than a raw API.
