AstraWrite

Your writing, your key, your assistant. AI-powered writing assistant with BYO API key support.

AstraWrite is an AI writing assistant for Chrome that works directly inside the places you already write. Instead of copying text into a separate app, you can open AstraWrite in a text field, textarea, or many rich-text editors on the web, choose what you want help with, and apply the result right away. What AstraWrite can help with: • Rewrite text for clarity and flow • Fix grammar, spelling, and punctuation • Shorten long drafts • Expand thin or unfinished writing • Summarize longer passages • Translate text into natural English AstraWrite supports OpenAI, Google AI, and OpenAI-compatible endpoints. You can choose the provider that fits your setup and use your own API key, so you stay in control of usage and costs. The writing flow is simple: 1. Add your API key in Settings. 2. Focus an editable field on a page. 3. Open AstraWrite with the floating button or press Cmd+Shift+Space on Mac / Ctrl+Shift+Space on Windows and Linux. 4. Choose a mode, review the result, and apply it. Built-in presets help you get the tone you want for supported tasks, and local history makes it easy to undo or redo AI-applied changes. Privacy is a core part of AstraWrite: • Your API key is stored locally in Chrome • AstraWrite does not require an AstraWrite account • Requests go directly to the provider you configured • AstraWrite does not route your writing through its own backend If you want AI writing help that feels fast, flexible, and under your control, AstraWrite is built for that workflow.
