How it works

How OpenRedakt takes a file from source to reviewed output.

Every format follows the same discipline: open the source, make it reviewable, find or mark sensitive content, decide on each mark, render a new file, and inspect what will actually be shared.

The review lifecycle

Six stages, the same for every format

The stages do not change between a scanned bundle, a recorded interview, and a dashcam clip. The tools inside each stage do.

The OpenRedakt project library: recent projects with their review status and a project to continue. Project names and folder paths are blurred.
01–02Organise and open projects
OpenRedakt manual redaction panel: select marks or text, draw a free-form area, choose the redaction appearance and record a reason from the reason library. No document is open in this view.
03–04Review and mark
OpenRedakt audio export dialog: the redacted copy is written as a new file with the chosen file type, audio output and export mode, and the original recording is left unchanged
05–06Export a redacted copy
  1. 01

    Open a supported source

    Bring a document or recording into the workflow suited to its format.

    Documents
    PDFs open natively. Supported office formats are converted for document review; several need LibreOffice installed.
    Audio
    Common audio formats open on a waveform and timeline once FFmpeg tooling is configured.
  2. 02

    Make the content reviewable

    Give the reviewer something to read or hear in context before any mark is made.

    Documents
    Native text is used where it exists; configured OCR recognises text on scans and image-only pages.
    Audio
    An available transcript can sit beside the waveform as context. It is not treated as an exact timing source.
  3. 03

    Find candidates or mark directly

    Use configured detection where it helps, and place marks yourself wherever judgement is needed.

    Documents
    Configured engines surface candidate findings; reviewers also select text or draw areas on the page.
    Audio
    Reviewers drag or enter the start and end of each sensitive span on the manual timeline.
  4. 04

    Decide, adjust, and record

    Every candidate and mark is a decision a reviewer makes, not one the software makes for them.

    Documents
    Approve, reject, or edit each mark, adjust its appearance, and record the reason for it.
    Audio
    Choose mute, tone, silence, or a supported noise mask and preview the effect where the source decodes.
  5. 05

    Render a new output

    Create a separate redacted file rather than relying on how the working project looks on screen.

    Documents
    Render a reviewed copy of the document from the approved marks.
    Audio
    Render reviewed ranges to a supported output format; output choices are narrower than accepted inputs.
  6. 06

    Inspect what will be shared

    Treat the exported file as another review step before anyone outside the workflow receives it.

    Documents
    Re-open supported output, check for readable marked content, and create a report of the recorded decisions.
    Audio
    Listen to the exported recording, paying particular attention to the boundaries of each masked span.

Human review

What the reviewer stays responsible for

  • Deciding what is sensitive for the intended recipient and purpose
  • Confirming or rejecting every candidate the software surfaces
  • Finding what detection does not cover, such as indirect identifiers
  • Listening to every masked span in the rendered recording
  • Inspecting the exported file before it is shared
