"I was paying $19/month for Merlin just for the summarizer and translator. NexTool gives me both plus 18 more tools for a one-time fee. Absolute no-brainer."

"The BYOK model is genius. I use my OpenAI key and pay maybe $2/month in API costs. That's it. No subscription, no middleman, and my data stays private."

"Finally, an AI tool that respects my privacy. My data goes straight to the AI provider, not some random startup's server. Plus the price is unbeatable."

FAQ

Common Questions

NexTool works with API keys from OpenAI (GPT-4), Anthropic (Claude), or Google (Gemini). You only need one key to get started. Getting a key is free and takes about 2 minutes — just visit the provider's website, create an account, and generate an API key. We have a step-by-step guide inside the extension.
The average NexTool use costs about $0.01 (one cent). A typical user spends $1-3 per month in API costs. Compare that to $16-20/month for subscription tools. Even heavy users rarely exceed $5/month. You can set spending limits directly on the API provider's dashboard.
Yes, completely. Your data goes directly from your browser to the AI provider (OpenAI, Anthropic, or Google). NexTool never sees, stores, or processes your data. Your API key is stored locally in your browser and never sent to our servers. This is the most private way to use AI tools.
Free gives you access to all 20+ tools with 10 uses per day and 1 API key. Pro ($49 one-time) removes all limits: unlimited daily uses, multiple API keys, custom prompts and templates, all future tools, and priority support. Once you buy Pro, you have it forever.
Yes. Every tool we build in the future is automatically included in your Pro license at no extra cost. We ship new tools every week. You paid once — you get everything, forever.
With the Free plan, you can use one API key. With Pro, you can add keys from all three providers (OpenAI, Anthropic, Google) and switch between them per tool. Want to use Claude for writing and GPT-4 for coding? No problem.
Getting an API key is free and takes 2 minutes. When you install NexTool, we walk you through the process step by step. OpenAI gives you $5 in free credits to start. You'll be up and running before you finish your coffee.
We offer a full 30-day money-back guarantee on Pro. If NexTool doesn't save you time and money, email us and we'll refund you immediately. No questions asked. We're that confident you'll love it.
