A real Pi session: the assistant inspects the Heart Nebula, adjusts star reduction and brightness and opens a previous-edit comparison, keeping the nebula and colours unchanged.

The details are yours to decide.
A starting point you can see. Fine adjustments you can judge. Room to find your own look.
See it before you choose it.

YOUR IMAGE. YOUR WORDS. REAL EDITS.Describe the look.
Describe the look.
Watch it take shape.
Connect Pi with your own supported AI account. Ask it to inspect your image, adjust the look or help with your workflow. The assistant works through AutoBru’s controls, and you see the changes in the app.
Keep the conversation beside your image. Compare each result, steer the next step or take over yourself.
REAL ASSISTANT SESSION
Read the conversation“Make the stars a little less prominent without changing the nebula or colours.”
Pi inspected the image, adjusted star reduction and brightness, and opened a comparison with the previous edit. The nebula and colour settings stayed the same.It can see what you’re working on.
The assistant can inspect your actual preview and current settings, then use the same stretch, palette, colour and star controls you do.
Help beyond the next slider.
Ask it to open projects, choose tools, prepare processing settings, manage palettes or work with saved versions. App control is built into the conversation.
You keep the final say.
Watch the actions as they happen. Steer or stop the assistant, compare before and after, and undo its edits. You can also ask for alternatives without changing your current look.
Your account. Your choice. Connect a supported provider through Pi. The assistant is optional; AutoBru’s manual controls are always there.

A FEW THINGS TO KNOW
Before your first edit.
Is AutoBru the same as Nebula Studio?
AutoBru is our desktop workspace, connecting local astronomy tools, an image editor and an optional AI assistant. Nebula Studio is the editor you can use directly in your browser.
Which computers will it be available for?
We’re preparing AutoBru for macOS, Windows and Linux. Each platform’s download will appear at the top of this page when its installer is ready. Platform requirements will be provided with the release.
What images can I start with?
Prepared AutoBru runs, or stacked linear mono FITS masters in H, H/O or H/O/S. The Siril workflow also handles supported original mono FITS and camera raw sessions with calibration frames. Input support is expanding as development continues.
Do I need paid tools or an AI account?
You can edit a prepared run without connecting an assistant. The current full processing pipeline uses licensed StarXTerminator for star separation, with either licensed NoiseXTerminator or free GraXpert for denoising. The optional Pi assistant connects to your own supported provider account.
Where does the processing happen?
Image processing runs through local tools on your computer. Exports are separate from your originals. If you connect the AI assistant, workspace context and image previews used in that conversation can be sent to your chosen AI provider.
