Apps that are a single verifiable file
Each app is a .lenscontainer: typed compressed columns, a Merkle root over every section, the app’s UI, and a per-number certificate scheme. It computes on the compressed data and runs entirely client-side — no server, no database. Open one below; it runs in your browser.
A full spreadsheet — multi-sheet workbooks, formulas, cross-sheet references, formatting, charts — that is a single file you can email to anyone. Every column total is a signed, re-checkable proof; every edit appends to a tamper-evident log instead of overwriting the file.
A financial-management dashboard — accounts, cashflow, categories, trends — packed into a single verifiable file. The whole app and its data run offline in your browser, with certified figures throughout.
The runtime every AT-1 app is built on. Point it at any .lens file and it runs the app inside — computing on the compressed data, signing every number. Build your own with the AT-1 Studio SDK.
Data, interface and proofs in a single file — no server, no install, no database.
Opens and runs on any device with a browser, with no connection at all.
Each figure is signed by a certificate an independent engine can reproduce byte-for-byte. One flipped byte and the file refuses to open.
