Capability · Reply agent · Add-on

An agent that handles your inbox while you're in lecture.

Optional $19/mo add-on. When a recipient replies, the agent drafts a response in your voice, parses suggested meeting times, books the calendar event, and notifies you. You walk out of class to a booked first-round.

Knows the second a recipient writes back.

The agent polls your provider's API on a short cadence. When a thread you sent gets a new inbound message, the agent classifies the reply: positive, scheduling, deflection, or noise. Acts only on the first two.

  • Per-thread polling — Gmail history.list / Graph delta
  • Classifier filters out OOO, auto-replies, and "thanks but no"
  • Pipeline row auto-progresses to "Replied"

Reads "Friday at 2pm" the way you do.

Most scheduling tools want links and slot pickers. Real cold-reply threads say "Friday at 2pm." The agent parses natural language, checks your Google Calendar for conflicts, picks the best candidate, and sends an event invite.

  • Natural-language datetime parser (timezone-aware)
  • Google Calendar conflict-check before booking
  • Auto-add Google Meet / Zoom link based on your default

Same voice as your outbound. Same sign-off.

The agent reuses the voice profile from your outbound drafts. Replies feel continuous with the first email — same opener pattern, same casual register, same "Manuel" at the end.

  • Same voice profile as outbound personalization
  • Mirrors the recipient's level of formality if they shifted it
  • Always sent from your address, never via relay

Hi Sarah,

Friday at 2pm works great. I just sent over a Google Meet for the slot — feel free to swap in your preferred link if Meet isn't ideal. Looking forward to chatting.

Best,
Manuel
