| Compared on | Kaer | Relevance AI |
|---|---|---|
| What it is | AI assistants for a business: email, calendars, business software and their own sandboxed browser. | A platform to build agents and workforces; it calls itself the “home of the AI Workforce”. relevanceai.com |
| Approvals | Stops before anything consequential: the message before it sends, the invoice before it is issued (kaer.ai/security). | Per tool or agent connection: Auto run, Approval required, or Let agent decide. Approval required “forces the agent to seek explicit approval before executing an action.” relevanceai.com docs: approvals |
| Standing schedules | Workflows run on a schedule or on a trigger: approve once, then it runs, with a record of every step (kaer.ai). | Scheduled triggers run an agent daily, weekly, monthly, on a custom cadence or by cron expression. relevanceai.com docs: scheduled triggers |
| Websites with no API | Its own browser and desktop on an isolated machine, destroyed when the run ends (kaer.ai/product/computer). | Through browser-automation integrations such as Airtop, connected with that provider's own API key. relevanceai.com docs: Airtop |

- You want an assistant that works on day one, without building agents first.
