@Heldly
Heldly is an AI-native scheduling agent for Claude. Tell Claude what meeting you want.
Heldly reads everyone's Google Calendar, places 3 holds across all hosts, sends a picker email to the invitee, and books the meeting when they choose.
Built for sales, partnerships, recruiting, and any external meeting that crosses orgs.
Overview
An AI-native scheduler for customer-facing teams — built to live inside Claude.
Describe the meeting in plain English. Heldly reads your Google Calendar directly, places tentative holds on every host's calendar, and emails the invitee a one-click picker. The moment the invitee picks, Heldly confirms the chosen slot and deletes the siblings across every host's calendar in the same request. No reusable booking page, no in-app form, no calendar cleanup.
Example prompts
- "Book a 30-min discovery with sara@acme.com for next Thursday or Friday afternoon."
- "Set up a 45-min renewal review with sara@acme.com — loop in marcus@yourteam.com as the second host."
- "Get a shareable picker link for an intro with Sara from Acme. I'll paste it into Slack."
- "Did Sara book the meeting?"
- "Reschedule the Acme walkthrough to next Monday afternoon."
What Heldly handles
- Multi-host meetings — up to 6 hosts. Heldly intersects every calendar and lands the chosen meeting on all of them at once with Google Meet attached.
- Shareable picker links — no invitee email? Paste-anywhere URL for Slack / LinkedIn DMs.
- One-sentence reschedules and cancels — Heldly cleans up every host's calendar (tentative holds, confirmed events, all of it).
- Workspace insights — funnel, time-to-pick percentiles, host leaderboard (Business plan).
