Install for VS Code, Cursor, and Windsurf, or add a Chromium and Firefox extension, then keep using your usual AI tools with no workflow changes.
Package.json is inspected on your own machine to match relevant ads, and only anonymous keyword tags are sent; source code is never read, stored, or transmitted.
Campaigns reach audiences defined by technologies in their code, such as React, Python, AWS, or Kubernetes, instead of third-party browsing cookies.
Withdraw earnings through Stripe or PayPal, or take API credits with a bonus, with referrals earning a share of what they bring in.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
