One person,
56 million tokens.

“I was too cheap to pay for subscriptions, too lazy to go through the whole multi-app workflow, and too unemployed, so I designed this app to turn my photos into masterpieces.”

10 — FAQ

Questions,
answered.

Is CHRO-MA-SMITH really free?

Yes. It's free, open-source software under the GPL-3.0 licence. There's no account, subscription or paywall.

Do my photos get uploaded anywhere?

No. Everything runs on your device, in the browser or the desktop app. Your photos never leave your machine.

What's the difference between the web app and the desktop app?

The web app has the full editor: looks, film effects, colour tools, masks and export. The desktop app adds the photo library, card import, on-device search, face tagging and the desktop-only tools such as HDR and focus stacking.

Does it work offline?

Yes. After the first load the web app keeps working without a connection, and the desktop app never needs one.

Which RAW files can it open?

Camera RAW files from any camera are decoded locally on your device. JPEG, PNG and TIFF open everywhere.

Can I use my own LUTs?

Yes. Load any .cube LUT as a starting look, or build your own .cube from a before/after pair or a reference photo.

How do I install it on iPhone?

CHRO-MA-SMITH isn't on the App Store yet. Download the .ipa and install it with a third-party signing service such as Flarestore. Or add the web app to your home screen, which needs no signing.

Where can I see every feature in a list?

Open the full feature list. Every tool, grouped by what it does, with a one-line description.

Is there a Windows version?

Yes. A Windows installer is published alongside the Mac release.

What is it made with?

The whole editor is one HTML file with plain JavaScript and no framework or build step. Rendering runs on WebGL2, with GLSL shaders for the look, grain, halation, bloom and tiled full-resolution export. RAW files are decoded locally with LibRaw compiled to WebAssembly, plus Adobe DCP camera profiles. The desktop app is a Tauri shell with a Rust core and a local catalogue database, for Mac and Windows. On-device masks use ONNX Runtime models (EdgeSAM and SegFormer). Video uses mediabunny, the iPhone app is a Capacitor shell, and the film looks were calibrated with Python tooling. It works offline through a service worker, and the source is GPL-3.0.

Now makeit yours.

Your photos. Your workflow. Your app. Free and open source on every device.

For the full experience, download the desktop app: the local library, card import, on-device search and face tagging all live there.
