Sintra

Sintra is an AI-employee platform that gives small businesses and entrepreneurs a team of role-based digital workers (e.g. Soshie for social media, Cassie for customer support, Milli for sales) that handle recurring day-to-day tasks like content creation, inbox management, copywriting, and SEO around the clock. It's built for founders and lean teams who want to delegate specific functions without adding headcount, and its differentiator is 'Brain AI' — a shared knowledge base that stores your brand voice, files, and SOPs so every helper produces on-brand output. It suits users automating a handful of defined tasks rather than teams needing fully autonomous, multi-step workflows.
