Payment infrastructure that lets AI agents pay securely on any PSP
Embed a checkout flow that an AI agent can trigger natively, so purchasing happens inside your app rather than via redirect.
Card details are vaulted with a PCI DSS Level 1 partner and never exposed to the app, the AI, or the LLM.
Each payment token is locked to a specific merchant and amount, with expiry and spending limits controlled by the user.
Users confirm each purchase with biometric approval such as Face ID or fingerprint, keeping them in control of their money.

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.
