Textus AI
Your writing assistant. It writes with you.
While you write
Pause, and the next words appear in grey. Tab takes them. Typos and grammar are flagged as you write, along with your own conventions. Alt+Enter fixes them.
When you ask
Edits arrive as proposals, each with a reason. Take one whole, or sentence by sentence. Comments pinned to the lines they mean. Notes, not rewrites. Tighten, proofread, translate, change the tone and more, one slash away.
It knows you
It learns your style, remembers your characters and places, and follows your instructions.
Any LLM you like
Textus works with more than 20 LLMs, and with any LLM that offers an OpenAI-compatible API.
OpenAI · Anthropic · Google Gemini · DeepSeek · xAI · Mistral · Groq · OpenRouter · Kimi · GLM · Qwen · Ollama · Any OpenAI-compatible endpoint
What you write is yours alone
Your writing stays yours. Textus is built so that it can, and its code is open so that anyone can check.
Documents are plain Markdown files, kept wherever you choose. API keys and sign-ins are stored only on your computer. AI requests travel directly from your device to the provider you pick. Download it and write. There is nothing to sign up for. No analytics, no telemetry, no ads. MIT-licensed and public, line by line, so anyone can verify all of this. With a local model through Ollama, your words never leave your computer.
