Frequently Asked Questions

YES - your data is completely safe. Here's exactly how it works:

• API Keys: Stored locally on your device using Chrome's secure storage. Never on our servers.
• Summaries: Communication goes directly from your browser to your chosen AI provider (10 options). We never see your summaries or browsing history.
• What we DO collect: Your email (for login), payment info (via Stripe - we never see your card), and subscription status.
• What we DON'T collect: API keys, browsing history, webpage content, or summaries.

NeuroBrowse is built for browsing. ChatGPT isn't.

Here's what makes us different:

• Works on ANY webpage: One-click summaries without copying/pasting
• Persistent sidebar: Stays open while you browse, remembers last 5 summaries
• 10 AI models: Switch between GPT, Claude, Gemini, Perplexity, DeepSeek, Grok, Kimi, Mistral AI, Groq, and Meta Llama 4 instantly
• Text highlighting: Select specific parts of a page to analyze
• Cross-page memory: Compare insights from different articles
• You control costs: BYOK means no markup, pay only for what you use

ChatGPT is great for conversations. NeuroBrowse is great for understanding what you're reading online.

Yes - 7-day money-back guarantee, no questions asked.

If you're not happy with NeuroBrowse within the first 7 days, email us at hello@neurobrowse.io and we'll refund your $5 subscription immediately.

Note: We can't refund API costs (those go directly to OpenAI/Anthropic/Google/Perplexity), but you can set spending limits to control costs.

It depends on what you're reading! Here's our guide for all 10 models:

• DeepSeek: Best value - excellent quality at lowest cost (~$0.0005/summary)
• Gemini Flash: Quick summaries with a generous FREE tier!
• Claude Haiku: Academic papers, technical documentation, long-form content
• GPT-4o-mini: Creative content, code tutorials, conversational summaries
• Perplexity Sonar: Current events, fact-checking, when you need citations
• Grok: Real-time info, X/Twitter context, witty responses
• Kimi: Very long documents, Chinese content
• Mistral AI: Efficient multilingual summaries, European data compliance
• Groq: Ultra-fast inference, near-instant responses
• Meta Llama 4: Open-source power, strong reasoning capabilities

The cool part? You can try all 10 models on the same page and compare results!

NeuroBrowse also auto-detects page type and suggests the best model for you.

Yes! NeuroBrowse works on any webpage with text content.

This includes:

• News articles and blogs
• Academic papers and research
• Documentation and wikis
• Social media posts (Twitter/X, LinkedIn, Reddit)
• Product pages and reviews
• GitHub repositories and code

The only limitation: paywalled content. If you can't read it in your browser, NeuroBrowse can't summarize it either.

Not quite - but API access is cheaper and more flexible!

ChatGPT Plus ($20/month) and Claude Pro ($20/month) are subscription products that give you unlimited chat access through their websites. They don't provide API access.

API keys are pay-as-you-go and typically cost less than $1/month for NeuroBrowse usage. Plus you get:

• Access to 10 models (GPT, Claude, Gemini, Perplexity, DeepSeek, Grok, Kimi, Mistral AI, Groq, Meta Llama 4)
• Faster response times
• No rate limits
• You only pay for what you use (~$0.001/summary)

Total cost with NeuroBrowse: ~$5-6/month vs ChatGPT Plus at $20/month
