v0.47Introducing Janus 1.0 Pro

The AI gent
for every tool you log into.

An AI agent that does the work, not just the talking. Supplier portals, booking systems, the back-office tool nobody can export from: Kaer works them in its own sandboxed browser and, by default, stops for your approval before anything consequential.

The work

One workspace for the work that keeps you open.

Answers, mail, schedules, the portals with no integration and the tool you have outgrown: one workspace your AI agents share, with one picture of the business.

What they do

Four skills. Every agent has them.

Each agent talks to customers, runs the software you already pay for, keeps the weekly routine and builds what is missing. They share one context, so nobody quotes the wrong number twice.

Kaer Agents

Staff that never clock off.

Six roles to start from, each one part of the business. Your agents work nights, weekends and the week you are away, and by default every one stops for your approval before anything consequential. Breeze runs one of your choice; bigger plans run more at once.

Who it's for

Find the page for your job.

Pick your role, or the job you want off your desk. Each page says what Kaer does there and where it waits for you.

Build & technical work

It builds the software too.

The booking form, the customer portal, the tool you have outgrown a spreadsheet for. Built the way an engineer would, and stopped where an engineer would ask.

Guardrails

It works alone. You draw the line.

Approvals, a full trail, your own tools, your own limits. Your agents run the work end to end and still stop at the line you drew.

Approval before it emails, posts or pays

Email from Kaer Mail or Gmail, Slack messages, social posts and payments wait for you by default. One tap, on any device, and the job carries on.

A record of every action

Every step, tool call and message is logged, so you can see exactly what each agent did and why.

Access scoped per tool

Each agent gets the connectors its job needs and nothing more. Revoke any of them in one click.

Limits you set, not defaults

Spend caps, working hours and the jobs an agent may take on. It stops at the ceiling instead of asking forgiveness.

Everywhere

One plan, everywhere you work.

Kaer in the browser, the Kaer Work desktop app, your phone and its own cloud computers, all on one plan, with leading open-source models included.

Kaer on the web

app.kaer.ai

The workspace your AI agents share: mail, diary, jobs, workflows and every approval, in any browser.

Cloud computers

Each job gets its own browser and desktop in the cloud, for the portals with no integration and the builds that need a machine.

How Computer works

Businesses on Enterprise add zero data retention (ZDR): prompts, files and outputs are processed, then not stored.

Billing

Priced by the work, not the login.

Three things decide what you pay: what your agents did, the ceiling you set, and nothing else.

Metered usage

Credits meter what your AI agents actually do: mail answered, workflows run, tools called, software built.

Plans

Monthly or yearly, at the ceiling you choose. A yearly plan is invoiced for ten and a half months and delivers twelve.

Four isometric blocks ringed around one larger central block on a round plate, thin lines linking each to the centre

Seats

No per-seat pricing. Up to 3 invited people share each workspace on every paid plan, so the bill follows the work rather than the headcount.

Kaer is free to start. Pay for more agents when the work grows.

*Fair use, no daily task limits. Free Mode spends no credits; Janus uses your plan, other models are pay as you go. Token amounts on Breeze, Cirrus and Stratus are typical for Janus; output-heavy work uses them faster.

Prices are in US dollars and exclude VAT. Where VAT or sales tax applies, it is worked out from your location and shown before you pay.

Questions

An AI agent that does the work.

Kaer Agents are AI agents that do the work in every tool you log into: each one has a role, instructions, skills and the tools it may use, works on its own or hands parts of a job to other agents, and stops for your approval before it emails, posts or pays.

What are Kaer Agents?
Kaer Agents are AI agents that do the work in every tool you log into: each one has a role, instructions, skills and the tools it may use, works on its own or hands parts of a job to other agents, and stops for your approval before it emails, posts or pays. Where a tool has a connector, an agent uses it. Where a site has no integration, such as a supplier portal, a booking system or an old back-office tool, it signs in and uses the web app in its own sandboxed browser, the way a person would.
What can a Kaer agent do?
Take a job from start to finish: work your inbox, keep the diary, run tasks and workflows by hand, on a schedule or from a trigger, operate the software you already use and build the missing tool, then report back. An agent can delegate part of a job to another agent and return one combined result, and it asks you on a card when something is unclear.
Where can I use Kaer Agents?
On the web at app.kaer.ai, from your own code through the Kaer API, and from Claude, ChatGPT, Claude Code, Cursor or Codex through Kaer's MCP server, so you can hand an agent a job from your IDE. Kaer Work, the desktop app at work.kaer.ai, runs them too. The Kaer app for iPhone and Android, for following and approving their work from your phone, is coming soon (waitlist at mobile.kaer.ai).
How is Kaer different from a chatbot?
A chatbot answers questions. Kaer's agents take the job: they work your inbox, run workflows on a schedule, operate the software you already use and build the missing tool, then report back. Consequential steps wait for you, and spending stops at the limit you set.
How many agents do I get?
As many as your plan runs. Breeze is $5 for the first month, then $9.99/month, with a 7-day free trial for new accounts, 999 credits a month and one AI agent of your choice. Bigger plans run more at once. Each agent takes a role, such as working the inbox, keeping the diary, chasing jobs or running the weekly routine, and they all share one workspace.
What does a Kaer subscription include?
Kaer Agents on the web, Kaer Work (a separate desktop app for Mac, Windows and Linux at work.kaer.ai, which builds in a project folder like an IDE and handles everyday tasks), cloud computers that give each job its own browser and desktop, and leading open-source models, all on one plan. The Kaer mobile app for iPhone and Android is coming soon (waitlist at mobile.kaer.ai). Businesses on Enterprise can add zero data retention (ZDR).
