Frequently Asked Questions
What's included in Free?
Everything except AI features. You get LaTeX compilation, Markdown and DOCX editing, PDF export, project organization, and local vault storage — all completely free. Upgrade to Pro to add the AI writing assistant, autocomplete, code execution, and more.
Can I try Pro for free?
Yes! All new users get a 14-day free trial of Pro when they sign up, so you can try the AI features before committing.
What AI models do you use?
We use the latest models, including OpenAI's ChatGPT 5.1 and 5.2 reasoning models, plus Kimi K2 and GLM-4.7. We wrap them with Nebula's agent architecture for better planning and long-form work.
Is my writing data secure?
Your writing stays on your device. We don't offer cloud sync yet, so nothing is uploaded by default. We never train AI models on your content.
Can I cancel anytime?
Yes, you can cancel your subscription at any time. You'll retain access until the end of your billing period.
