Every time you share an image, paste text into an AI model, or reuse the same password across sites, you're leaving a trail. The good news: you don't need expensive software or technical knowledge to protect yourself. These five free browser-based tools handle the most common privacy risks — and none of them require an account or send your data anywhere.
1. Strip Location Data from Your Photos
Every photo your phone takes embeds EXIF metadata — including your exact GPS coordinates, the device model, and the timestamp. When you share that image on forums, marketplaces, or in messages, that data goes with it unless you remove it first.
Vibe-Check
Strip EXIF, GPS, and camera metadata from images before sharing.
Vibe-Check processes everything locally in your browser. Your images never leave your device — the metadata is stripped client-side and you download the clean version instantly.
2. Redact Sensitive Data Before Pasting Into AI
Copying code, emails, or documents into AI chatbots is second nature now. But how often do you check whether that text contains API keys, email addresses, social security numbers, or other personally identifiable information? Probably never.
AI-Text Scrub
Redact API keys, emails, SSNs, and PII before pasting into AI models.
AI-Text Scrub scans your text for common PII patterns and redacts them before you paste into any AI model. It's a 5-second habit that prevents the kind of data leaks that companies spend millions trying to fix after the fact.
3. Generate Passwords You'll Never Have to Remember
Password reuse is still the number one cause of account compromises. A strong, unique password for every service — combined with a password manager — eliminates this risk entirely.
Password Generator
Generate secure random passwords with customizable length and character sets.
OneKit's password generator uses your browser's cryptographic random number generator — the same mechanism used by professional password managers. Customize length, character types, and copy with one click.
4. Verify File Integrity with Hashes
Downloaded software from a third-party site? A hash lets you verify that the file hasn't been tampered with. Compare the SHA-256 hash of your download against the one published by the developer — if they match, the file is clean.
Hash Generator
Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes instantly.
5. Make Your Site Transparent to AI Agents
This one's for site owners. As AI agents crawl the web on behalf of users, having an llms.txt file tells those agents exactly what your site does, what's available, and how to interact with it — on your terms.
LLMS.txt Generator
Create AI-agent-readable manifest files for your website.
All five of these tools are free, run in your browser, and never send your data to a server. That's the point — privacy tools that actually respect your privacy.
The Bigger Picture
Privacy isn't a single product you buy. It's a set of habits. Stripping metadata before sharing photos, scrubbing PII before pasting into AI, using unique passwords, verifying downloads — each takes seconds and compounds over time into a meaningfully more secure digital life.
Every tool in OneKit is built on this principle: your data stays on your device. No accounts, no uploads, no tracking. Just tools that work.
