Tentmate is an AI agent designed to work directly inside Basecamp projects, rather than in a separate app or browser tab. Teams can invite it to a project, mention it in a comment, or assign it a to-do, then interact with it through familiar Basecamp workflows. Tentmate can handle a range of project work, including turning pitches into structured projects and to-do lists, reviewing recorded customer calls, building landing-page prototypes from brand materials, investigating software bugs, and analyzing business data from connected services such as Stripe and PostHog.

It can also produce evidence-linked findings, create project documents, generate page content and images, and open pull requests with tests for identified code issues. Its work can run through long-running sessions and deferred or recurring tasks, allowing it to continue beyond a single conversation. Tentmate is presented as a collaborative team member whose work and outputs remain within the projects where it is invited
