1 · Upload case files

PDF, DOCX, TXT — drag & drop, pick multiple, or a whole folder. Scanned pages are OCR'd. Every page is indexed for citation.

Drop files or a folder here, or

2 · Analyze

Auto-populates names, dates, addresses, timeline & evidence (page-cited), then produces the investigative synopsis & task list.

Chain of custody · audit log

Append-only record of every action on this case — creation, uploads, analysis, task changes, exports, downloads. Tamper-evident, Brady/discovery-ready.

Photo evidence board

Every photo from the case files and your uploads, consolidated with its citation. Click to enlarge; select two or more to compare side-by-side or overlay with adjustable transparency. Enhancements are view-only — the stored original is never altered.

No photos yet — upload images, or upload PDFs/DOCX and their embedded photos appear here.

Message decipher · riddles, poems & ciphers

Paste a coded note, riddle, poem, or cipher. Offline decoders (Caesar, Atbash, reverse, acrostic, A1Z26) run instantly on this machine; the engine can also interpret meaning and hidden structure. All local — nothing leaves the box.

Investigator synopsis

M.O. signature & similar cases

Abstracted, de-identified signature — the only layer eligible for nationwide matching. Similar cases are ranked across your own library; each shows why it matched.
