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.

One AI assistant for every system your customer support team works in
Works across your dashboards, mail client, CRM and public websites, so the same assistant is available wherever a customer question lands.
After dashboard setup, it queries your organisational knowledge to give answers grounded in how your business actually works.
Adapts to the site or system you are on so support stays consistent across every touchpoint your team uses.
Lets the assistant take an action on the customer's behalf when an inquiry requires it, instead of just answering.
