Agents

Your scheduling agent does the grinding.

recon-agent watches your inbox for scheduling requests, holds your candidate slots, negotiates across other people's agents, and books with consent. You see a recap — never fourteen back-and-forth emails.

  • Inbox-aware: agent reads scheduling intents and proposes slots
  • Agent-to-agent negotiation across organisations
  • Soft holds, hard holds, focus blocks — all consent-gated
  • Recap-only updates: one notification instead of fourteen

Thanks for the kind notes on the balanced variant. Attaching the redlined v3 with the requested term changes — net-45, mutual indemnity, and the data-residency rider you flagged. Happy to walk through it on Thursday at 4 PM if useful.

Global

Timezone-native, not timezone-aware.

Every event carries its origin timezone. Cross-team meetings render correctly for every attendee, with daylight savings handled, working-hours respected, and travel surfaces planned automatically.

  • IANA timezone-native event storage
  • Working-hours per person, per region
  • Travel-aware: flights, jet lag, blocked focus on landing days
  • Universal time bar — see 09:00 across every team at a glance

recon-agent gave me Fridays back. Not "Friday afternoon" — the whole day. I forgot what protected time felt like.
