The self-driving workspace that remembers everything about your operations
A living organisational record that organises every message, meeting, deal update and workflow event into entities, relationships, timelines and dependencies.
An editable, automatically maintained layer for priorities, open loops, SOPs and operating principles — the judgment side of your assistant.
Agents that orchestrate across Gmail, Slack, CRM and 20+ tools, triggered by events or on a schedule.
Dex can navigate tabs, fill forms and complete tasks directly in your browser, cutting context switching.
The agentic AI browser that reads your tabs, files, and screenshots as context
Drop in a tab, a file, a screenshot, or a highlighted element and the agent reads, plans, and runs on it — no copy-pasting between apps.
Automate multi-step tasks on real websites, including deep research, form filling, and data collection, with several agents working in parallel.
Ready-made Skills for the sites you actually use — video triage, podcast highlight extraction, PDF table export, PR explanations, subscription audits — plus a builder for your own.
Switch between a broad menu of leading models from multiple vendors, with your chosen model always shown at the top of the chat.
