Answers you can show your work on
Everything below is in the version on the Microsoft Store today.
Cited answers
Ask in plain words. SourceToMe quotes the passages that answer it, each tagged with its source, and a coverage meter says whether the evidence is strong, thin or missing.
Sources disagree? You see both
When two passages make opposite claims or give different numbers, it shows both side by side instead of blending them. Different editions of one document get an “editions differ” note.
Prove it's offline
One click shows the app's outbound connections, name lookups and the local address it serves on (127.0.0.1 only). A badge always says Offline or Cloud AI.
A refusal test you can run
50 questions its library can't answer. Run it and watch it decline instead of making something up. In our tests it refused 50 of 50.
Starts with 35 references
Consumer rights, digital safety (US and UK), food safety, AI prompting and retrieval, and programming, with attribution and license notes for each. Or bring your own PDF and get a cited answer with the timed first-run guide.

Optional cloud AI, off until you turn it on
SourceToMe works fully offline by default. If you want a written answer in plain sentences, turn on Cloud AI in Settings and add your own OpenAI key, or point it at an OpenAI-compatible endpoint you choose.
- Before it sends anything, it shows exactly what will go: your question, the selected passages and a short coverage label.
- Nothing else from your library leaves your PC. Answers are labeled “Cloud AI” and must cite your own passages.
- Your key is stored on your PC with Windows protection, shown masked, and removable any time. Usage is billed by your provider.
- Add from link downloads the web page you enter, once. Everything else works without the internet.
Questions
How much is it?
Try it free, then $19.99 on the Microsoft Store. Microsoft handles the trial, payment and licensing. Optional Cloud AI is billed separately by your provider.
Do I need an AI key or an account?
No. Search, answers, checks and the refusal test all run on your PC with no account and no AI key.
How reliable is the claim check?
Claim checking matches meaning on your PC and is a strong hint, not a guarantee. A claim can only be checked against what's in your library, so read the quotes before you rely on a result. The disagreement check is deliberately strict: it only fires on clear cases.
What PCs does it run on?
Windows PCs with x64 or Arm64 processors (native on Windows on Arm), installed from the Microsoft Store.
