x.ai pioneered AI meeting scheduling through email. Helppa takes a different approach — real-time conversational AI via shareable links, no email access required. Here's how they compare.
| Feature | Helppa | x.ai |
|---|---|---|
| Current status | Active — free to use, actively developed | Acquired by Calendly in 2021; x.ai product discontinued, team integrated into Calendly |
| Scheduling approach | Guest chats with AI via a shareable link — no email access needed | AI assistant (Amy/Andrew) operated via email — CC the AI on a thread to schedule |
| Email access required | No — Helppa only reads your calendar (events-only scope) | Yes — x.ai needed full email access to read and send messages on your behalf |
| Real-time interaction | Yes — guests chat with Jane and get instant responses | No — email-based, so responses took minutes to hours depending on processing |
| Conversational AI | Yes — powered by Claude, handles nuance and natural language | Yes — but limited to email thread context; no real-time back-and-forth |
| Privacy model | Calendar-only scope — no inbox access, no contacts, no email reading | Required email access — could see inbox contents to process scheduling threads |
| Setup time | Under 60 seconds — connect Google Calendar, share your link | Several minutes — connect email, configure preferences, learn CC workflow |
| Team scheduling | Multi-host links — Jane finds times that work for all teammates | Supported — CC Amy on a group thread |
| Free tier | Yes — 10 meetings/month, no credit card required | N/A — product discontinued |
| Best for | Anyone who wants AI scheduling without giving up email access | Was best for heavy email users who preferred scheduling within existing threads |
x.ai was one of the first AI scheduling assistants, launching in 2014 with virtual assistants named Amy and Andrew. You'd CC them on an email thread, and they'd negotiate meeting times on your behalf. It was a clever approach — scheduling happened inside the communication channel people already used.
In 2021, Calendly acquired x.ai and integrated the team into their product. The standalone x.ai service was discontinued. If you were an x.ai user looking for a replacement, the question is: what's the best AI scheduling assistant available now?
If you specifically want an AI that lives inside your email threads, Calendly (which acquired x.ai) now offers some AI-assisted features within their platform. However, this requires broader email permissions and a Calendly subscription.
Most professionals today prefer the link-based approach — it's simpler to set up, doesn't require email access, and works across any communication channel. That's why Helppa was built this way.
Share one link. Jane chats with your guests, finds the right time, and books it on your Google Calendar. No email access needed. Free to start.
