What is Kaer?
Kaer makes the AI agent for every tool you log into. You tell it what needs doing, like chasing last month's unpaid invoices or sending a quote, and it does the job in your email, your calendar and the web tools you already log into. Payments, and the emails and messages it sends with its own tools, wait for your approval by default.
The jobs owners hand over
- EmailReads, drafts, sends and follows up from the inbox you already use.
- Web apps with no integrationLogs into supplier portals, booking systems and back-office tools in its own sandboxed browser, and works through them the way you would.
- Routine jobsRuns the weekly and monthly work on a schedule, and stops to check with you before anything risky.
- Small toolsWhen no app fits the job, it builds a small one for you.
How you stay in charge
You describe the job in plain words. Kaer works out the steps, does them, and shows you what it did. Payments, and email, Slack messages and social posts sent through Kaer's own tools, wait for your approval by default. You choose what may go out without asking.
We never use your data to train third-party models. “Help improve our services” is on by default: Kaer learns from how you use it, with secrets removed, and you can turn it off any time in Settings. The privacy policy has the detail.
