## What it does

Coherence replaces a fragmented stack of CRM, email client, calendar, and project
tools with one workspace where data flows naturally between functions — instead of
context-switching between disconnected apps.

## Key features

- **Two-way email sync** — emails appear on contact records; send from CRM or client.
- **Calendar integration** — meetings linked to contacts and projects automatically.
- **Custom modules** — build any data structure (projects, vendors, inventory) without code.
- **Workflow automation** — trigger actions based on data changes.
- **Nash, the AI agent** — runs on a schedule, plans and executes tasks, briefs you.
- **Unified search** — find anything across all your business data.

## Who it's for

Small teams and solopreneurs, marketing and creative agencies, consultants and
freelancers, service-based businesses, and anyone managing complex relationships
beyond just customers.
