How to Use AI on Any Webpage Without Sharing Your Data
52% of AI Chrome extensions collect your data. Use AI on any webpage with your own API keys (BYOK) — no subscriptions, no data collection. Prompt GPT, Claude, or Gemini directly.
52% of AI Chrome extensions are collecting your data. 29% are collecting personally identifiable information. And two fake AI sidebar extensions were caught stealing complete chat histories from 900,000 users.
If you've been using AI through a browser extension, there's a coin-flip chance your prompts, responses, and browsing activity are being logged on someone else's server. If you've followed the data privacy conversation in browser automation, these numbers keep getting worse.
The fix isn't to stop using AI in your browser. It's to stop letting someone else's server sit between you and the AI provider. Bring Your Own Keys (BYOK) means your API keys stay in your browser, your requests go directly to OpenAI, Anthropic, or Google, and nobody in the middle touches your data.
This guide covers how Prompt Anything Pro works, why the BYOK model saves you 70-90% versus subscriptions, and how to set it up in under five minutes.
What Is Prompt Anything Pro?
Prompt Anything Pro is a Chrome extension that lets you select text on any webpage and prompt AI with it instantly. Highlight a paragraph, click the floating button, pick a template or write your own prompt, and get a response — without leaving the page.
The core difference from extensions like Monica, Sider, or Merlin: you connect your own API keys. Your prompts go directly to OpenAI, Anthropic, or Google. No middleman server. No data collection. No subscription markup on top of the API cost you're already paying.
Here's what that looks like in practice:
- Select text on any webpage — an article, documentation, an email, a code review
- Click the floating button that appears near your selection
- Choose a provider (OpenAI, Anthropic, or Google) and a preset template or custom prompt
- Get the response in a clean overlay. Save it to your prompt library if you want to keep it
Everything runs locally. Your API keys are stored in Chrome's local storage, not on a remote server. Your prompt history stays on your device unless you choose to export it.
45 AI Prompt Templates for Every Workflow
Most AI extensions give you a blank text box and leave you to figure out the prompting. Prompt Anything Pro ships with 45 ready-to-use templates organized by what you're actually trying to do.
| Category | Templates | Best For |
|---|---|---|
| Writing & Email | 4 | Grammar, tone, rewrites, email drafts |
| Coding | 6 | Explain, debug, security audit, refactor, docs |
| Research & Study | 5 | Summaries, study notes, compare & contrast |
| Business & Strategy | 6 | SWOT, meeting notes, risk assessment |
| Content Creation | 5 | SEO, headlines, outlines, FAQ, CTAs |
| Analyze, Social, Creative, Data, Productivity, Translate | 19 | Decision matrices, tone rewrites, data insights, translations |
For Writers and Editors
- Improve Writing — rewrites your selection for clarity and flow
- Make Professional — adjusts tone for business communication
- Grammar & Spelling Check — catches errors without sending keystrokes to a third-party server
- Draft Email Response — generates a reply based on the email you've highlighted
For Engineers and Developers
- Explain Code — breaks down what a code block does, line by line
- Find Bugs — identifies potential issues in highlighted code
- Security Audit — flags vulnerabilities and suggests fixes
- Refactoring Suggestions — recommends cleaner implementations
- Code Review Checklist — generates review criteria for the selected code
- API Documentation — writes docs for the code you highlight
Six coding templates is more than most general-purpose AI extensions offer. And because your prompts go directly to the AI provider, you're not sending proprietary code through a third-party proxy server — a real concern if you care about data ownership in your browser tools.

Additional Categories
Analyze — Pros & Cons Analysis, Extract Action Items Social — Tweet/Social Reply generation Creative — Tone rewrites, counterarguments, analogies, jargon simplification Data — Data Insights, Trend Analysis, Hypothesis Generation Productivity — Decision Matrix, Goal Breakdown, Time Estimation Translate — Translate & Explain (translation with context)
All templates work with any provider — OpenAI, Anthropic, or Google. You can also save your own custom templates to the prompt library and reuse them across any webpage.
Privacy: How a BYOK AI Chrome Extension Compares to the Alternatives
The Incogni 2026 study analyzed 442 AI Chrome extensions. Here's what they found about the category as a whole:
- 52% collect at least one type of user data
- 29% collect personally identifiable information
- 22% track activity down to individual keystrokes
- 42% require the scripting permission, which allows injecting code into web pages — potentially affecting 92 million users
The popular extensions aren't exempt. Writing assistants like Grammarly and QuillBot were flagged as the most potentially privacy-damaging popular extensions, collecting website content, personal communications, keystrokes, scrolling behavior, and navigation events.
Here's how Prompt Anything Pro's architecture compares to the major subscription-based alternatives:
| Prompt Anything Pro | Monica AI | Sider AI | Merlin AI | MaxAI | |
|---|---|---|---|---|---|
| Data collection | None | Yes | Yes | Yes | Yes |
| API key storage | Local (your browser) | Their servers | Their servers | Their servers | Their servers |
| Prompt routing | Direct to provider | Through Monica | Through Sider | Through Merlin | Through MaxAI |
| Tracking/analytics | None | Yes | Yes | Yes | Yes |
| Your prompts on their servers | No | Yes | Yes | Yes | Yes |
The distinction matters. When you use a subscription-based AI extension, your prompts travel through the company's proxy server before reaching OpenAI or Anthropic. That's a third party reading your prompts — even if their privacy policy says they don't log them. You're trusting a promise, not a technical guarantee.
With BYOK, the technical architecture is the guarantee. Your browser makes a direct API call to OpenAI, Anthropic, or Google. There's no middleman server to trust or distrust because it doesn't exist in the chain.
The Cost Math: BYOK vs. AI Extension Subscriptions
Most subscription AI extensions charge $5-20/month. They're buying API access from OpenAI or Anthropic at wholesale rates and reselling it to you at a markup. That markup pays for their servers, their data pipeline, their team, and their profit margin.
With BYOK, you pay OpenAI, Anthropic, or Google directly at their published API rates. For most users, the savings are significant.
The typical user sends about 30 prompts per day, 5 days a week — roughly 600 prompts per month. Here's what that actually costs at current API rates:
| Model | Cost per prompt (avg) | Monthly cost (600 prompts) |
|---|---|---|
| GPT-4o | ~$0.01 | ~$6 |
| Claude Sonnet 4.5 | ~$0.015 | ~$9 |
| Gemini 2.5 Flash | ~$0.002 | ~$1.20 |
| Gemini 2.5 Flash Lite | ~$0.001 | ~$0.60 |
Now compare that to subscription pricing:
| Extension | Monthly cost | Yearly cost |
|---|---|---|
| Prompt Anything Pro (BYOK + extension) | $6.99 + ~$1-9 API | $29.99/yr + API |
| Monica AI | $8.30 | $99.60 |
| Sider AI | $4.20 | $50.40 |
| Merlin AI | $19.00 | $228.00 |
| MaxAI | $12-30 | $144-360 |
Prompt Anything Pro's lifetime license is $49.99 — a one-time payment. At Monica's rate of $8.30/month, you break even in six months. Against Merlin's $19/month, you break even in under three months. After that, you're only paying API costs — which for most users run $1-9/month depending on the model.
If you use Gemini 2.5 Flash for most tasks and only switch to GPT or Claude for complex reasoning, your total monthly cost after the lifetime purchase drops to under $3/month. Try finding that deal with a subscription extension.
The same local-first architecture that makes this cost-effective is what keeps your data private — no cloud servers means no infrastructure costs passed on to you and no data sitting on someone else's machine.
