Your AI assistant
Asta
Harness
Asta works in your email, calendar and documents. Hand it a task and it gets on with it, checking with you before anything that matters.
How it works
Hand it a task. Asta does the rest.
Tell Asta what you need in plain words. It works out the steps, uses your tools to do them, and stops to ask whenever something can't be undone.
Ask
Say what you need
Write the task the way you'd tell a colleague. There's nothing to set up for each one.
Work
It uses your tools
Asta reads your inbox, checks your calendar and updates your tracker, using only the tools you've switched on.
Check
It asks before it acts
Sending, changing or deleting anything waits for your OK. One tap to allow it, one to say no.
Done
Nothing left behind
Files and commands run in a sealed workspace with no internet access, and it's wiped when the chat ends.
Approvals
Nothing important happens without you.
When Asta wants to send, change or delete something, it stops and shows you exactly what it's about to do.

Hi Priya, your cards left the printer this morning. Here's the tracking link.
- Asta waits for your answer. Nothing is sent or changed until you reply.
- Allow an action once, for the rest of the conversation, or always for your team. You can take it back at any time. Sending an email asks every time unless an admin allows it for the team, and you see exactly who it goes to.
- When a tool needs a password or key, Harness adds it to the request itself. The AI never sees it, and it's wiped as soon as the request is done.
Memory
It remembers what matters, not everything.
Asta keeps a short profile of your preferences, and you approve every line. It looks things up when it needs them and never trawls through your old chats.
- Prefers short answers; expand only when asked.
- Works in Lisbon; mornings are for deep work.
- Invoices go out on the last Friday of the month.
"What did we agree with Northwind?"
- Payment within 30 days, agreed in March.
- Orders ship from the Leeds warehouse.

Your tools
Works with the tools you already use.
Connect the apps your team lives in. Asta only touches the ones you switch on, and only as far as you allow.
Gmail
Google Calendar
Google Drive
Linear
Atlassian
Microsoft TeamsComing soon
Every tool starts switched off. You choose how far Asta can go with each one: read only, draft for you to send, or make changes.
Reliability
Never stuck waiting on one AI.
Asta can use more than one AI model. If one is slow to answer, another takes over within seconds, so your task keeps moving.
Start
Hand Asta its first task.
