Free plagiarism checker
Is any of it
already online?
GPT Nada searches the web for several passages of your essay and shows you anything that matches closely. Only short phrases leave our computer, about nine words each, sent to Brave Search.
Search the webFree. No account. Your text is wiped when the check finishes.
How it works
- Paste your essay or upload the file, then open the Sources tab.
- Press Search the web. This one waits for you, because each search has a small cost.
- GPT Nada picks several passages, searches for them, and shows any web pages with matching wording, with links so you can check them yourself.
What it does well
- Finds wording that is too close. Useful for spotting a sentence you meant to quote or put in your own words.
- Private. Only short phrases are searched. The rest of your essay stays on our computer and is wiped afterwards.
What it cannot do
- It searches the open web. It cannot see other students' essays, paid journals or private databases, so it is not a replacement for the checks your school or university runs.
- It checks several passages, not every sentence.
- Web searching has a monthly allowance. If it runs out, Sources rests until next month and everything else keeps working.
Who it is for
Students checking their own work before they submit, and markers who want a quick look at whether a passage appears online.
Questions
Is the plagiarism checker free?
Yes. Each browser can run about ten web searches a day, within a monthly allowance for the whole site.
Is it the same as Turnitin?
No. Turnitin compares work against its own private collection of student papers. GPT Nada searches the open web, so it finds published pages, not other people's coursework.
Why does it not run by itself like the other tools?
Every web search has a small cost, so Sources only runs when you press its button.
