Field Investigation & Evidence Tools

Review ordinary, testable possibilities for a specific observation before drawing conclusions. Each status and note is investigator-entered; the tool does not rank explanations or label anything pa...

Compare manually recorded baseline readings with a later observation at the same marked point. Use calibrated instruments, note their position, and report the raw difference instead of calling a ch...

Record a pre/post-session check against a known reference for each instrument. Enter the manufacturer’s stated tolerance yourself; this page does not invent calibration limits or certify a device.

Create a local inventory of selected evidence files with file metadata and SHA-256 hashes for manageable files, then append handling events. This helps detect later file changes; it does not prove ...

Capture an independent first-pass transcription before revealing the question or expected phrase. Then replay, record a second pass and compare the notes without the tool supplying words.

Pre-register a small A/B field test before you start: define the question, conditions, repetition count and scoring rule, then generate a balanced random order. This helps separate an observation f...

Build a clear field report that separates direct observations from interpretations, records methods and limitations, and includes permission and ordinary-explanation checks. Nothing is saved or sen...

Keep a neutral, timestamped field log while a permitted investigation is underway. The clock is manual; observations are written by your team, not inferred from sensors.

Make a simple, address-free room grid for a permitted site. Plot observer positions, instruments, control points, measurements or no-go hazards so a team can describe where a note came from.

Capture a witness’s account in their own words, then record context separately. Use open prompts, interview witnesses individually, and avoid suggesting a sound, figure, or cause.
