Collatorium
Weaving patterns from the page.
Every reading of a page, side by side. Settle the hard spots yourself. Keep the record — in your own files.
“The Analytical Engine weaves algebraical patterns just as the Jacquard-loom weaves flowers and leaves.”Ada Lovelace, Note A, 1843
How it works
Collatorium is the viewer; the archive stays where it already lives. Nothing leaves your computer or your institution's cloud.
Read and compare
Every leaf at full resolution, right way up. Every reader's text laid side by side — human, handwriting recognition, blind AI readers — with the close-up for each disputed spot.
Agreement is not proofRule and keep
Choose a reading, correct a word, flag a doubt. Each click is saved to your folder under your name, with the evidence, and never overwritten.
Nothing deleted, everMany readers, one record
Collatorium brings every reading of a page into one view: the handwriting-recognition text, independent large-language-model readers from different families, and the human editors who decide. The models read blind — letters before words, no outside knowledge, refuse rather than guess — and their agreement is treated as a signal, never as proof.
Where readers differ, the page shows the close-up, each reading, and a blank to rule. Every ruling is kept with its evidence and the name of the person who made it. The machines follow; the reader decides.
