Open-source database of AI models, prices and capabilities
Every model uses a consistent provider/model format so the same model across providers can be compared directly.
Side-by-side context window, output limit, reasoning, tool calling, structured output, and temperature support.
Input and output prices per million tokens listed alongside release and update dates.
Covers closed flagship APIs and open-weight models from many labs in one sortable catalogue.

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.
