Halumo: Photo Editor

Every photo has a moment worth doing justice to. Halumo is a photo editor built to get you there, with precise manual control over every adjustment and AI that turns what you describe into a finished starting point.

• Fix lighting by editing exposure, highlights, shadows, and more with precision sliders. Shape contrast with a full Tone Curve, and edit colour with hue, saturation, and luminance. • Apply built-in presets, previewed on your own photo before you commit to them. • Adjust parts of a photo selectively with manual masks for local retouching. • Crop, straighten, correct perspective, and remove lens distortion. • Describe the look you want in your own words, and AI turns it into a full set of edits you can see, adjust, or undo like any other change. Turn on Visual AI when you want it to read the photo itself. • Compare before and after with a split view. Every edit is non-destructive and stays undoable until you save. • Save a full-resolution copy back to your library, or share it anywhere. • Shoot with the built-in camera and open every frame for editing the moment you take it, with the original saved untouched in the background.

Halumo edits the photos already in your library through the Photo Picker, so your library stays exactly as you left it.

An account is only needed for AI editing. Browsing, editing, and saving all work on their own. Sign in with Apple, Google, or Microsoft, and every account includes a monthly allowance of AI generations at no cost.

Halumo works the same way on Mac, Windows, and iPhone: the same adjustments, the same presets, the same editing behaviour wherever you work.
