Private documentation tool

Record what happened.
Separate fact from inference.

Create a structured record of an event, preserve exact language, hash related files, and export a copy you control.

This tool organizes information. A file or record fingerprint can show whether exact digital content changed; it does not prove that a statement is true, when an event occurred, or who created it. This is not legal advice, an official report, or an emergency service.

Context

Identify the event.

Record title (optional) Your name or alias (optional) Event date Approximate time Location or platform People present or involved

Evidentiary record

Keep each category distinct.

Direct observation is what you personally saw, heard, received, or experienced.

Secondhand information is what another person told you.

Inference is your interpretation, theory, or question.

What I directly observed Exact words or exact text What someone else told me My inferences, concerns, or open questions Witnesses or possible corroboration Actions already taken Follow-up needed

Digital fingerprints

Hash related files locally.

Choose files only when it is safe. The browser calculates a SHA-256 fingerprint for each file; the file itself is not stored in the record or uploaded.

Choose files to fingerprintPhotos, screenshots, audio, video, PDFs, or other files. Large files may take time.

No files selected.

Build the record

Create your controlled copy.

I reviewed the record and distinguished direct observation, quotations, secondhand information, and inference to the best of my ability.

RECORD SHA-256

This identifies the exact generated JSON. Any change creates a different fingerprint.

Optional encrypted vault

Lock a copy in this browser.

The record is encrypted with AES-GCM using a key derived from your passphrase. The passphrase is never stored and cannot be recovered.

Passphrase (10+ characters)

No encrypted records saved in this browser.

Back up an export. Clearing browser data, using private browsing, or losing the device can erase this vault.
