Brinn is a personal AI assistant designed to help people organize everyday information and stay on top of important tasks. Available through WhatsApp and a web app, it lets users capture notes, reminders, and documents by text, voice, or file upload. Brinn can transcribe voice notes, identify useful details in files, and save information in a searchable private workspace, so users can retrieve notes, links, and documents when needed.

The service supports reminders, checklists, shared tasks, task boards, and daily briefings, helping individuals and teams coordinate priorities across devices. It can connect with Google Calendar for schedule updates and send timely notifications through multiple channels. A web dashboard provides tools to manage, search, and export a workspace. Brinn also offers a Chrome extension for saving links and context, while mobile and desktop apps are listed as part of its product lineup; the mobile app is marked as coming soon. By bringing captured information and follow-ups together, Brinn aims to reduce the effort of juggling tasks across separate apps.
