What it does
An assistant that works in your files
Not a chat window that tells you what to do. Astra opens the folder and does it, in front of you.
It works in a folder, not a chat box
Point Astra at a folder on your computer. It reads what is there, writes the changes you ask for, and shows you each one before it happens.
You describe the outcome
Say what you want in ordinary words. There is no syntax to learn and nothing to install alongside it. The work happens in front of you, visually.
Paid from your credits
Sign in with your CircuitNotion account and the app spends from the same wallet as everything else. You can see the running cost as you go.
Windows
If Windows says it protected your PC
This is expected, and it is not a warning about Astra. Windows shows it for any installer whose publisher it has not seen often enough yet. Two clicks get past it.
Why does it appear at all?
Microsoft Defender SmartScreen keeps a reputation score for every application publisher. A new installer has no score yet, so it is shown as unrecognised. The message is about how many times Windows has seen the file, not about what is in it. The warning goes away on its own as more people install it.
Check you have the real file
Every download here starts at www.circuitnotion.com over an encrypted connection, and Astra checks that each update it installs was signed by us before it will run it. If somebody sends you an Astra installer from anywhere else, do not run it.
Updates
You only install it once
Astra checks for new versions by itself and tells you when one is ready. You never need to come back to this page.
It checks on its own
Astra asks for the current version when it starts. There is nothing to subscribe to and no newsletter to watch.
It tells you in the app
When a new version is out, a notice appears inside Astra saying so. Your work is not interrupted and nothing is downloaded until you say yes.
One click installs it
Choose to update and Astra fetches the new version, verifies it was signed by us, and restarts into it. Your projects and settings are untouched.
Every update is cryptographically signed, and Astra refuses one whose signature does not match the key built into the application. That is what stops anybody who can intercept a download from replacing an update with something else.
Questions
Before you install
What people ask about Astra: what it costs, what it runs on, and what that Windows warning means.
What is Astra?
Astra is a desktop AI agent from CircuitNotion, an AI company in Kigali, Rwanda. It is built for everyone, not only developers: you describe what you want in ordinary words and it does the work on your computer, the way you would yourself, showing you each change before it happens.
Who makes Astra?
CircuitNotion, an AI company based in Kigali, Rwanda. The same company makes the circuit-2-turbo model and runs the CircuitNotion API, and Astra spends from the same credit balance.
Is Astra free to download?
Yes. The application is free to install. You sign in with a CircuitNotion account, and the work Astra does is paid for from your credit balance, with the running cost visible as you go.
Which operating systems does Astra run on?
Windows 10 and 11 on 64-bit, Debian and Ubuntu on 64-bit as a .deb package, and Mac on both Apple silicon and Intel.
Why does Windows say it protected my PC when I run the installer?
Microsoft Defender SmartScreen keeps a reputation score for every publisher, and a new installer has no score yet, so Windows shows it as unrecognised. The message is about how often Windows has seen the file, not about what is in it. Choose More info, then Run anyway. The warning disappears on its own as more people install it.
Is Astra safe to install?
Every download here starts at www.circuitnotion.com over an encrypted connection, and Astra verifies that each update it installs was signed by us before it will run it. If somebody sends you an Astra installer from anywhere else, do not run it.
How do I install the Linux package?
Double-click the .deb file, or install it from a terminal with sudo apt install ./ followed by the file name.
How does Astra update itself?
Astra asks for the current version when it starts and tells you inside the app when a new one is ready. Nothing is downloaded until you agree, and the new version is checked for our signature before it is installed. Your projects and settings are untouched.
How do I pay for what Astra does?
From the same CircuitNotion credits as the API. You top up in Rwandan Francs with Mobile Money, or with a card billed in RWF or US dollars, and Astra spends from that balance as it works. There is no subscription, and unspent credits stay in your wallet.
