AI agents people actually use
Short answer: If you want a chat assistant, start with Grok Bot (xAI) or Claude (Anthropic). If you want a proactive personal agent that works across apps, the vendor pages to read are Claude Duet, OpenAI Dots and Meta Muse. Cofounderbase does not sell these products; we list agencies that build custom AI apps and automations when a consumer agent is not enough.
Facts below are taken from each maker’s public pages (checked 2026-11-03). We do not invent prices, user counts or awards. Access and plans change — confirm on the linked pages.

Questions
What is the difference between a chat assistant and a personal AI agent?
A chat assistant answers when you ask. A personal AI agent is built to keep working across your apps (email, calendar, connected tools), often with its own computer, and should ask before consequential actions. Claude Duet, Dots and Muse are marketed as personal agents; Claude and Grok Bot are general assistants you chat with.
Which products does this page cover?
Grok Bot (xAI), Claude and Claude Duet (Anthropic), Dots (OpenAI) and Muse (Meta). Each row links to the vendor’s own page. Checked 2026-11-03.

No. Cofounderbase is a directory of agencies that build custom AI apps, automations and internal tools. This hub compares personal/work agents people actually use, then links to hiring guides if you need something custom.
