Three builds ship from this site. SEO Note 2.1 is the current one: an Electron app (about 121 MB installer) for Windows 10/11 64-bit and Linux x64, with Markdown, the tree editor, AI talking to a model you connect — a local one or any OpenAI-compatible endpoint, a web clipper and git sync of the file. For Android 6.0 and newer there is a release-signed APK (~10 MB) of the same interface; on the phone notes live as a folder of Markdown files on the device, and passwords, sync, the clipper and AI answer there with an explicit refusal. The classic build 1.3.34 (~2.5 MB, Win32) stays on the download page for Windows 7, 8 and 32-bit PCs, where 2.1 does not install; its notes file is .seo. All three work offline with no account: pick your build, or read how 2.1 and 1.3.34 differ.
