Why I Built This
Creative software has a problem. Most tools require accounts, store your work on someone else's server, and charge monthly fees for access to your own files. If the company shuts down, your work is at risk. If your subscription lapses, you lose access. Creative work is personal, often sensitive, and always yours. The tools you use should respect that.
I built Croma Creative Suite first and foremost for myself. I wanted professional creative tools that were free, private, and simple to use, with nothing to install and no account required. Then I decided to share them, so you can use them too.

Everything you need to know about Croma Creative Studio.
Croma is a creative suite of browser-based applications that share a common design philosophy. It brings together specialized creative tools, from image editing to long-form writing to story development, so you can move seamlessly between different kinds of creative work without leaving your browser.
Pixel is Croma's professional image editor. It supports layers, masks, blending modes, adjustment layers, vector shapes, and advanced editing tools. Everything runs directly in your browser with no installation required.
Books is Croma's long-form writing and publishing app. Write, structure, and publish manuscripts and ebooks, from first draft to export in EPUB, Kindle, and PDF formats.
Story is Croma's narrative development tool for writers, screenwriters, and filmmakers. Plan and visualize your story structure with characters, scenes, timelines, relationship graphs, beat sheets, and an infinite canvas. All before you write a single line of prose or dialogue.
Yes. All Croma apps are free to use. There is no account required, no subscription, and no feature gating. Open any app and start creating immediately.
Yes. Every Croma app runs entirely in your browser using standard web technologies: HTML, CSS, and JavaScript. There is nothing to install, no plugins to enable, and no backend server processing your data. Your files stay on your computer.
Croma works best in the latest versions of Chrome, Edge, Brave, and other Chromium-based browsers. Safari and Firefox are supported with minor limitations (e.g. the File System Access API is only available in Chromium). For the best experience, keep your browser up to date.
No account is needed. You need an internet connection to load the app initially, but once loaded, all Croma apps work fully offline. Your projects are saved locally using IndexedDB and the File System Access API.
Completely. Croma apps process everything locally in your browser. No data is uploaded to any server, no analytics track your content, and no third-party service ever sees your files. Your creative work stays on your machine.
We believe creative work is personal. Your drafts, your ideas, your unfinished projects belong to you alone. That is why every Croma app is designed to run entirely on your device. There is no cloud sync, no server-side processing, no telemetry on your content, and no account that ties your identity to your work. We chose this architecture deliberately: if your data never leaves your browser, it can never be leaked, sold, or used to train models. Privacy is not a feature we added. It is the foundation we built everything on.
