Sintra

Sintra is a no-code AI-employees platform that gives small businesses a team of role-based digital workers. It ships 12 specialized AI helpers — such as Soshie (social media), Cassie (customer support), Seomi (SEO), Buddy, and Vizzy (meeting notetaker) — that handle social media, inbox, content, customer support, SEO, and sales and business operations. Users chat with helpers, schedule recurring background tasks, build custom helpers with the Helper Builder, and connect tools like Facebook, Instagram, Gmail, Google Calendar, Outlook, Google Drive, Notion, and Strava through consumer OAuth integrations. Sintra is a portfolio company of Earlybird Venture Capital. As of this profile Sintra publishes no public developer API, OpenAPI, or API reference — it is an end-user low-code product rather than a developer platform.

Sintra is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, AI Agents, AI Employees, and Automation.

Sintra’s developer surface includes documentation, getting-started guide, support, engineering blog, pricing, signup flow, and 12 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/sintra: open an issue to ask a question, or submit a pull request to add artifacts.
