Pre-built AI API endpoints that return clean JSON
More than 30 endpoints span resume parsing, job matching, invoice extraction, translation, SEO tags, content summarization, sentiment and product description generation.
Test real endpoints in the browser on bundled sample documents and text, and see the same JSON your application would receive.
Turn any AI prompt into your own production REST API endpoint when the standard catalog does not cover a bespoke need.
Each subscription holds at least one credit that grants a monthly word quota; credits can be added or removed as volume changes.
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.
