Tdaycom

tday (tday.com) is a Y Combinator-backed (Spring 2026) AI platform, operated by Altacomm Technologies Pty. Ltd. of Adelaide, South Australia, that turns what a software team ships into on-brand creative. It connects to a company's GitHub repository or drives a live site through the browser like a user, and on every release produces a launch package — an end-to-end demo video recorded from real product flows, a promotional feature showcase, and on-brand social graphics — then publishes that creative to social channels and measures how it performs. A second surface generates brand-aware still designs from a text prompt against a stored brand, where a brand is created from a website URL and its colors, fonts and logos are extracted automatically. tday operates with no SDK embedded in the customer's product, using isolated per-run workspaces and database branches, scoped repository access, secure credential storage, and secret redaction. Its developer surface is agent-shaped rather than REST-shaped: tday publishes no OpenAPI, and instead ships a hosted Model Context Protocol server at https://tday.com/api/mcp secured with OAuth 2.1 (PKCE, dynamic client registration, RFC 8414 / RFC 9728 discovery), a local stdio MCP server distributed on npm as @designtday/mcp, and five of its own packaged agent skills.

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

Tdaycom’s developer surface includes documentation, signup flow, support, pricing, changelog, authentication, CLI, and 20 more developer resources.
