Questions
Yes. It is free and open source under the MIT license, with no account and no subscription. If you use Textus AI, your provider bills you directly, or not at all with a local model.
macOS (Apple Silicon and Intel), Windows and Linux, and iPhone and iPad from the App Store (not yet in mainland China).
We care a great deal about memory and measure it in every release. A window takes about 110 MB, and each further window about 55 MB more. Plugins load only when they are used, and a web page left in the background is let go and loads again when you come back to it.
No. The editor works fully without AI. For Textus AI, connect a provider of your own: sign in with ChatGPT or Claude, add an API key, or run a local model with Ollama.
The editor does, completely. Textus AI needs your provider, unless you run a local model.
Yes: plain .md files, with tables, task lists, footnotes, math and Mermaid. You can export to PDF, Word, HTML and more.
