Tdaycom

tday (tday.com) is a Y Combinator-backed (Spring 2026) AI platform that turns a software product into on-brand marketing content. It connects to a company's GitHub repository or live website, and on every release automatically produces a launch package — an end-to-end demo video generated from real product flows, feature showcases, and on-brand social graphics and ads — then publishes that creative to social and ad channels and measures how it performs, closing the loop from what a team ships to what it posts. tday operates through the browser like a user, with no SDK embedded in the customer's product, using isolated per-run workspaces, scoped repository access, secure credential storage, and secret redaction. tday exposes a hosted Model Context Protocol (MCP) server at https://tday.com/api/mcp secured with OAuth 2.1 (PKCE, dynamic client registration, RFC 8414 / RFC 9728 discovery), making it the agent-facing surface of the platform.

Tdaycom publishes 1 API on the APIs.io network. Tagged areas include Company, Marketing, Artificial Intelligence, Content Generation, and Video.

Tdaycom’s developer surface includes support, authentication, and 9 more developer resources.
