You know the concept but not the word. Maybe you want to tell an AI to "make a formatted text file with headings and code blocks" but can't remember it's called Markdown. Or you're describing "when the app remembers you're logged in between visits" and you're reaching for the term session persistence. ReverseJargon closes that gap: describe it in plain English, and get the exact term back with a no-nonsense explanation, real examples, and use cases — so you can talk to AI tools and teammates precisely.
No. Just type your description and hit Find Term — there's no sign-up, no login, and nothing to install. ReverseJargon is powered by Google's Gemini AI behind the scenes, so you get instant answers with zero setup.
Yes — completely free to use, with no paywall. Ask as many questions as you like; ReverseJargon is here to help you find the right term whenever you need it.
Your description is sent securely to Google's Gemini AI to generate the answer, and nothing is stored or logged on our side. We don't ask for any personal information to use the tool.
Novice and experienced developers, people new to "vibe coding", students, technical writers, and anyone who wants to describe an idea and get the precise term to use with AI tools or in their work.
ReverseJargon is a free, AI-powered reverse dictionary for technology. A normal dictionary goes from a word to its meaning; ReverseJargon works the other way around — you already understand the idea, you just don't know (or can't remember) the exact word for it. You type a plain-English description of the concept, and ReverseJargon returns the precise technical term, a clear no-nonsense explanation, real-world examples, and common use cases, all on a single screen.
It was built for the age of AI coding assistants. To get good results from tools like ChatGPT, Claude, Gemini, Copilot or Cursor, you need to ask for the right thing using the right vocabulary. If you don't know that the "green squiggly underline that suggests fixes" is called a linter, or that "sending data to a URL automatically when something happens" is a webhook, your prompts stay vague and your results suffer. ReverseJargon hands you the exact word so you can communicate precisely with both AI and human teammates.
Type what the thing does in your own words — no jargon required. For example, "when code retries automatically until it works".
Google's Gemini AI interprets your description and identifies the single best-matching term.
You instantly see the term, a plain explanation, examples, and use cases — ready to copy into your prompt or work.
Here are just a few of the countless descriptions ReverseJargon can turn into the exact term:
Whether you're writing code, drafting documentation, prepping for an interview, learning a new framework, or just trying to sound precise in a stand-up, ReverseJargon gives you the vocabulary to say exactly what you mean.
