Xyterna：我打造了一款可根據個人文件作答並附上來源的應用程式

I built Xyterna, and this is a 98-second look at it with the real app.

The idea is simple: you add receipts, bills, warranties and documents as they come in, as photos, files or whole folders. Xyterna reads them, keeps the original file, and organizes what matters into records that stay connected.

Two design decisions mattered most to me:

Every answer points back to its source. Ask "When does my warranty run out?" and you get the answer plus a link to the exact document it came from, so you can check it.
It doesn't guess. When dates are unclear or two documents disagree, it says so and asks you, rather than quietly picking one.

On top of that, Home surfaces bills, renewals and dates found in your documents, and reports group records by topic for export as a spreadsheet or PDF.

There's a read-only demo account with fictional data you can open without signing up: https://www.eternaclarity.com/xyterna/demo/

I'd love feedback from other builders, especially on the "ask instead of guess" behaviour.
