AI voice agent inside Cal.com workflows that phones attendees to confirm, book, reschedule and follow up on meetings.

Manus
General AI agent that carries out multi-step tasks such as research, slides, websites and design from a single prompt.
What is Manus?
Manus is a general-purpose AI agent that does the work behind a request instead of only replying with text. From one prompt you can ask it to run deep or wide research, build slides, deploy a website, create designs, or make images, music and video, and it can also run recurring tasks as scheduled automations. It is available on the web, in mobile and desktop apps, through a Slack integration and through an API, with a Team plan that adds SSO and admin controls. Work is metered in credits that depend on task complexity. The Free plan costs $0 per month and refreshes 300 credits daily, Pro starts at $20 per month with 4,000 monthly credits, a higher Pro tier is $40 per month with 8,000 credits and a 7-day free trial, and the Team plan starts at $20 per seat per month. Annual billing saves 17 percent. Individuals, freelancers and teams use Manus as an alternative to ChatGPT agent mode for research and deliverable creation.
