Morning briefs. Relationship intelligence. Human-approved outreach. Everything runs on your device — no cloud, no subscription, no data leaving your phone.
Cossi connects your calendar, contacts, email, and tasks — and gives you one clear view of what matters each day.
Cossi reads your calendar, cross-references your relationships, and surfaces conflicts and nudges before your first meeting. No setup wizard. No prompting required.
Green / amber / red signal based on meeting load, overdue tasks, and conflict detection — at a glance.
Cossi detects when an open decision blocks a meeting, or when a relationship hasn't been touched before an important call.
Tap play on any event. A 4-section spoken brief covers context, stakeholders, open threads, and the 80/20 lever.
Cossi tracks interaction signals — meetings, emails, tasks — and builds a live health score for every person. You see drift before relationships fade.
Interaction frequency, recency, and signal diversity combined into a single 0–100% score per contact.
Record a note about anyone. Cossi transcribes it and surfaces it automatically the next time that person appears in a meeting brief.
Set a reminder and Cossi creates both a task and a calendar event. Pending follow-ups surface in your morning brief.
Cossi has no server-side user accounts, no analytics pipeline, and no AI model API calls. The AI runs locally on your device. Your contacts, calendar, emails, and vault never leave your hardware.
