Why glunty
Browser-first
Most tools run entirely in your browser. Your input never leaves your machine. The exceptions (AI-augmented tools) are clearly labeled and explain what gets sent and where.
No interruptions
No modal asking for your email. No "subscribe to use this tool." No paywall after the third use. The tool you came for works immediately.
No accounts
Nothing to sign up for. AI-augmented tools have a generous per-IP daily limit; that is the only rate-limit you will encounter. Most tools have no limit at all.
No tracking
No third-party scripts, no behavioral profiling, no fingerprinting. The privacy policy says what we collect (almost nothing) in plain English; you can read it in under a minute.
For developers and writers
Each tool page comes with a copy-paste embed snippet (run the tool inside your own site) and a citation widget in 5 standard formats (URL, Markdown, BibTeX, APA, MLA) so you can reference the tool in writing or research without friction. The catalog is also available as RSS, sitemap, and llms.txt for AI crawlers.
What this is
Most online utility tools are buried under modals, paywalls, and ads that block you from doing the thing you came to do. glunty does not. Every tool here loads fast, works immediately, and stays out of your way.
The catalog grows as new tools ship. If a tool you want is not here yet, the about page explains how to suggest one.
Frequently asked questions
- Is glunty free?
- Yes. Every tool is free to use. There is no paid tier, no premium features hidden behind a paywall, and no advertising that interrupts the tool above the fold. AI-augmented tools have a generous per-IP daily limit; that is the only rate-limit on the site.
- Do I need to sign up?
- No. Nothing on glunty requires an email, phone number, or account. The tools work the moment the page loads. AI-augmented tools have a per-IP daily limit but no sign-in.
- Where does my input go for AI-augmented tools?
- AI-augmented tools forward the input you paste to Anthropic Claude for processing and return the response. glunty does not log or store the input. Anthropic processes it for the duration of the request under their data-usage policy (no training on API inputs by default). Each AI-augmented tool page has a more detailed FAQ on what gets sent.
- How do I embed a glunty tool on my site?
- Every tool page has an "Embed this tool" section near the bottom that produces a copy-paste iframe snippet. The embed strips the site chrome via ?embed=1 so the tool runs cleanly inside your layout. Free for any use; attribution to glunty.com appears at the bottom of the embed body.
- How do I cite a glunty tool in academic or technical writing?
- Every tool page has a "Cite this tool" section with five standard formats: plain URL, Markdown link, BibTeX, APA 7, and MLA 9. Pick the format that matches your citation style and copy the snippet. The publication year is 2026; access date is left as a fillable placeholder where the style expects one.
- Does glunty track me?
- No third-party trackers, no behavioral profiling, no fingerprinting. The site uses no advertising scripts and no analytics SDK that follows you around the web. The privacy policy spells out exactly what is collected, which is almost nothing.
