The Nexio Suite
Every Nexio extension shares the same Pro subscription. One key, all tools.
FAQ
Yes. Nexio AI injects a sidebar on any webpage you visit - news articles, research papers, dashboards, forums, documentation sites. The extension reads the visible page text and gives Claude the context it needs to answer your questions.
Anthropic is the company that makes Claude - the AI model powering Nexio. On the free tier, you connect your own Anthropic account so API costs go directly to them (typically $1-3/month for normal use). Get a key at console.anthropic.com - new accounts include free credits. If you prefer zero setup, Pro handles all of this for you.
1,000 requests per month. Each question you ask or summary you generate counts as one request. This is enough for dozens of sessions per day. The quota resets on the 1st of each month.
Free tier: your queries go directly from your browser to Anthropic - Nexio servers never see your conversations or page content. Pro tier: requests are routed through our backend proxy to Anthropic. We do not log or store conversation content. Your Pro key is stored only in your browser's local storage.
Yes. Cancel anytime from the link in any of your receipt emails, or email us at [email protected] and we'll cancel it for you. You keep Pro access until the end of the billing period. We also offer a 14-day money-back guarantee on your first payment - no questions asked.
