Many plugins also hand Textus AI their own tools, so you can ask for what they do in a conversation. The plugins are in textus-plugins and the themes in textus-themes, where you can share your own.
Questions
Is Textus free?
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.
Which platforms does it run on?
macOS (Apple Silicon and Intel), Windows and Linux, and iPhone and iPad from the App Store (not yet in mainland China).
How much memory does it use?
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.
Do I need an AI account?
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.
Does it work offline?
The editor does, completely. Textus AI needs your provider, unless you run a local model.
Is it plain Markdown? What can I export?
Yes: plain .md files, with tables, task lists, footnotes, math and Mermaid. You can export to PDF, Word, HTML and more.
