Search a whole dataset offline, in one file, the AT-1 Living Database™ demos
An AT-1 Living Database™ is a single .htmlfile that holds both the dataset and the query engine that searches it. Open it in any browser and search the whole thing offline — nothing is uploaded, and the original data is byte-exact recoverable from the same file.
Each demo below is a real dataset packed into one file. Open it in your browser, or download it and double-click it later. No install, no server, no account.
Common Crawl

Simple English Wikipedia
Single fileA whole encyclopedia: every article title and summary, searchable offline in one file.
Built with the same verified-lossless AT-1 core: the data inside each file is recoverable byte-for-byte, and an embedded SHA-256 lets the decoder confirm nothing has changed.
Run one without downloading anything
The files above are the ones you keep. These run in the page, and none of them send your data anywhere: the engine is doing the work in your browser, which is the claim and also the demonstration of it.
Drop a .lens file in and a certified dashboard builds itself. A 6,000 event sample is provided.
3,000 sealed records, one erased on request, and the certificate proving the rest was untouched.
Apps that are a single verified file. The LENS viewer runs inside the page.
A working spreadsheet over 20,000 rows with certified totals and tamper-evident edits.
A finance dashboard where the data, the queries and the proofs are one file.
Run the engine in your browser on a file you choose. Nothing is uploaded.
