promptShield vs Redactable for document redaction
Redactable is a cloud platform — your documents are uploaded, redaction is permanent, and you pay per document. promptShield runs fully offline and replaces data with stable codes you can run through any AI and decode back. A sourced feature comparison, dated and cited.
The difference in one sentence
Redactable uploads your documents to the cloud and permanently redacts them — fast, collaborative, and final. promptShield keeps every byte on your machine and replaces sensitive data with stable, consistent codes you run through any AI, then decode back to the real values.
Redactable is built for teams that redact-and-release at volume: browser-based, real-time collaboration, permanent destruction of the sensitive content. That's a genuinely good fit for legal and compliance teams producing final records. But two lines are different. First, your files are uploaded to the cloud to be processed — promptShield never uploads anything, it runs offline on your machine. Second, Redactable's redaction is permanent and irreversible — there's nothing to send to an AI and bring back. promptShield is built for the anonymize → AI → decode loop, where the same entity always gets the same code so the AI can follow the conversation.
Where the two genuinely diverge
Offline vs cloud upload
Redactable is a browser platform: you upload documents to be redacted, with cloud-storage import from Google Drive, Dropbox, OneDrive and Box. For many teams that convenience is the whole point. But the file leaves your control. promptShield never uploads anything — detection and redaction run on your machine, air-gap capable, so the confidential document and its real values stay on the same disk they started on.
Reversible codes vs permanent destruction
Redactable states that nothing can be recovered or reverse-engineered from a document it has redacted — true, irreversible destruction, which is exactly right for a final release. promptShield instead replaces each value with a structured, reversible code (e.g. [P0ABCD]): the meaning survives, the real value never leaves, and you can restore it later. Sealing a document versus getting a working copy you can decode.
The decode loop a redact-and-release tool doesn't have
Because the redacted value is destroyed, there's nothing to hand to ChatGPT, Claude or Gemini and no way to bring an answer back. promptShield closes that loop: anonymize into stable codes, send to any AI, then import the response and decode every code back to its real value. An auto-generated instruction page tells the AI to keep codes verbatim.
Flat license vs per-document billing
Redactable bills by the number of documents you redact each month — a Starter plan covers 15, Pro Plus 150 — so a heavy month means an upgrade or pay-as-you-go credits. promptShield is a flat license with no document meter: redact as much as you like, offline, at no extra cost. A meter is a tax you keep paying on your own throughput.

When to choose Redactable
Redactable is the right tool when:
- Your team redacts together — shared workspaces, permissions, comments and activity logs matter more to you than offline processing.
- You're producing final, sealed records for release where permanent, irreversible redaction is exactly the goal — and uploading to a cloud service meets your compliance bar.
- You want a zero-install browser tool with built-in import/export from Google Drive, Dropbox, OneDrive and Box.
These tools target different workflows. Redactable is a collaborative cloud platform for redact-and-release at team scale; promptShield is an offline desktop tool for the reversible anonymize → AI → decode loop on documents that must never leave the machine. Which fits depends on whether your files can go to the cloud at all.
When to choose promptShield
- Your documents can't leave the machine — confidentiality, client privilege, or a no-cloud policy means upload is a non-starter.
- You want to use an AI (ChatGPT, Claude, Gemini…) on those documents — anonymize, send, then decode the answer back to real values.
- You need reversible tokenization — replace a value with a code, then restore it later — not an irreversible blackout.
- You'd rather pay a flat license than a per-document subscription that forces an upgrade in a busy month.

Honest caveats
- This is not a detection benchmark. Redactable is a closed cloud product; we can't run its detector over our test documents the way we do for open-source tools. We compare approaches and features, not measured detection rates. For reproducible benchmarks, see /compare.
- Redactable's redaction is genuinely permanent. It strips metadata, hidden layers and residual data so nothing can be reverse-engineered. That's a strength for final release — it's simply the opposite design goal from promptShield's reversible codes, not a flaw.
- Collaboration is Redactable's edge. Real-time shared workspaces, permissions and audit trails are central to it and promptShield doesn't aim at team collaboration. We compare the redaction / personal-data workflow, not the collaboration suite.
