What people ask about the apps.
- Can I use Noplag without installing anything? +
- Yes — the web app runs in any browser today, free for up to 2,500 words per check, no signup and no download. The native apps below are conveniences on top of that, not a requirement.
- When do the apps ship? +
- We're rolling them out after the web relaunch. The browser extension, Word add-in, and desktop app come first; Google Docs and mobile follow. Join the waitlist and we'll email you the moment each one is ready — we won't post a store link until it actually works.
- Will the apps cost extra? +
- No. Every app signs into your existing Noplag account and uses the same plan and the same free allowance. There's no separate app purchase.
- Which browsers will the extension support? +
- Chrome and Microsoft Edge first — they share the same extension package — with other Chromium browsers to follow. The extension shows results in a side panel and never uploads a page you didn't ask it to check.
Don't wait for the download.
