UP TO 7 DAYS PER TASK
Its own computer
A Linux machine in the cloud with a terminal and files. It keeps its tools, logins and notes between tasks, so tomorrow it starts where it left off.
WORKING NOW · ANY HOUR OF THE DAY
Give it a task.
It works around the clock.
Every Lark agent has its own computer in the cloud: a terminal, a browser and your tools. It researches, builds and follows up while you sleep, and checks in when it needs you.

Your agents don't
keep office hours
They start when you ask, on a schedule, or the moment another service sends a webhook. A task can run for minutes or days. Here's one agent's day.
- Nightly checksRan the test suite, all green. Nothing to report.
- Morning briefRead the dashboards, emailed what changed overnight.
- You added something"Also check the EU numbers." It read it before its next step.
- New lead, from a webhookResearched the company in a browser, wrote a one-page brief.
- Competitor changed pricingSpotted it, took a screenshot, posted to Slack.
- Asked you"Publish the draft, or wait for review?" You tapped Wait.
A computer of its own,
and you on call
Not a chatbot: a worker with a real machine, a browser it drives, and your tools. It remembers what it learned, and it keeps you in the loop without needing you there.
24/7 SCHEDULES + WEBHOOKS
Starts on its own
On a schedule in your time zone, or when your CRM, form or GitHub sends a webhook, with what they sent folded into the task.
LIVE SCREEN

Talk to it mid-taskAdd to the task while it works. It reads your message before its next step.
It asks when stuckA login it doesn't have, a call only you can make: you get one question, answer in a tap.

Learns your waysTurn a run that went well into a skill, and every agent does it right next time.
Ask once.
It handles the rest.
Tell Frankie, Lark's assistant, what you need. It sets up the agent, the schedule or the webhook. Nothing that costs money starts until you press Start.
Say what you need
"Whenever a lead signs up, research them and send me a brief." Frankie picks the model, writes the instructions and sets up the webhook.

Questions
What can a Lark agent do?
Anything you could do on a computer with a terminal and a browser: research the web and write a report, fix code and open a pull request, check a dashboard every morning, follow up on new leads, or watch a site for changes. It works on its own machine in the cloud, so it keeps going after you close your laptop.
Can it really run day and night?
Yes. Agents start when you ask, on a schedule in your time zone, or when another service sends a webhook. A single task can run for hours or days, and an agent can keep its machine, files, browser logins and notes between tasks.
What happens when it gets stuck?
It asks you. You get a notification, answer in one tap, and it carries on. You can also message it while it works, or take over its browser to log in or show it something, then hand it back.
Which AI models and agents can I use?
Claude, GPT, GLM and DeepSeek are included, with no API keys needed, and you can run them with Lark's built-in agent, Claude Code, Codex or Aider. Pick per agent.
How much does it cost?
Free includes $1 of usage a month. Pro is $29 a month with $25 of usage included, and Team is $99 with $100. Every run shows what it cost as it works, and a monthly budget stops agents exactly where you set it.
