The layer between your product and AI.

Command+K exists because shipping a production-grade AI feature still means stitching together half a dozen vendors: an MCP host, a chat widget, per-user auth, usage metering, spend caps, billing. We build that layer as one platform, so product teams can go from an OpenAPI spec or GraphQL endpoint to a monetized, in-product AI assistant in an afternoon.

The platform stands on three primitives — Build MCP (publish your API as a hosted MCP server your customers connect to with their own accounts), CMD+K Widget (an in-product chat that acts as the signed-in user), and Monetize (meter every AI interaction back to your own billing). Each works standalone; together they replace the stitched stack.

Command+K is founder-led and built in the open — new capabilities ship weekly and land on the changelog. If you want to see where the product is going or push on where it should go, the fastest way is a conversation.
