How Redactable Works
Redactable is a cloud-native redaction platform. You upload your document, their AI engine scans it for sensitive data, you review and approve suggestions through a browser interface, then download the result. Four detection modes are available: fully automatic scanning, category-based detection, keyword search, and manual selection.
Both tools offer AI-powered detection. Both run in a browser. The difference is where your documents go. Redactable processes files on their servers - your document must leave your device to be analysed. RedactProof processes documents in your browser: the file physically cannot reach external servers because the standard engine never sends it.
The Upload Question
Redactable encrypts files with AES-256 at rest (FIPS 140-2 validated) and TLS 1.2+ in transit. They hold SOC 2 Type II certification and meet HIPAA requirements. These are real, auditable credentials.
Whether those credentials satisfy your data governance policy is a separate question. An HR team handling employee grievance files, an NHS trust processing patient discharge summaries, or a council responding to a Subject Access Request may have policies that prohibit uploading sensitive documents to third-party cloud infrastructure regardless of encryption or certifications. The document still leaves your network.
Under data protection regulations including GDPR and CCPA, uploading documents containing others' personal data to a third-party processor creates a new processing relationship. That typically requires a Data Processing Agreement, an entry in your Record of Processing Activities, and potentially a Data Protection Impact Assessment. Some Data Protection Officers flag this as a structural concern when the entire purpose of the processing is to protect that same data.
RedactProof's standard engine never sends document data anywhere. The Precision Engine sends extracted text - not the document file - to Cloudflare Workers AI, processed in volatile memory for inference only. The PDF stays in your browser.
Pricing and Document Limits
At the time of writing (May 2026), Redactable offers 3 free documents to trial the platform. Their Starter plan is $19/month for up to 15 documents per month. Pro Plus is $99/month - or $79/month on annual billing - for up to 150 documents per month. Enterprise pricing is custom.
Monthly document caps create unpredictable costs for anyone with irregular workloads. A busy period of disclosure requests or a bulk project pushes you into a higher tier or onto pay-as-you-go rates. Capterra reviews consistently flag cost as a friction point for smaller teams.
RedactProof's free tier has no document limit for pattern-based recognition. Paid plans from £19/month include unlimited AI detection with no per-document quotas. Process as many files as the job requires without watching a counter.
After Detection: Verification
Redactable generates a Certificate of Completion with each redaction - a record of who redacted what and when. Useful as an activity log for compliance reporting.
RedactProof embeds an Ed25519 digital signature in every export. Modify a single byte of the redacted document after export and verification fails. A QR code on the certificate lets anyone check document integrity without special software. The distinction matters when demonstrating to a regulator or recipient that the document has not been altered since redaction.

Who Switches from Redactable
Not every organisation that moves away from Redactable is doing so for the same reason. Three patterns come up regularly.
HR managers handling employee records
A benefits administrator at a mid-size manufacturer needed to process TUPE transfer documents containing salary bands, performance reviews, and medical information. Their IT policy prohibited uploading personally identifiable employee data to external SaaS platforms - a common restriction in organisations with ISO 27001 certification. The cloud upload requirement ruled Redactable out before any feature comparison started. RedactProof processed the same documents in the browser without touching the network. For HR teams, the constraint is usually policy-first.
Compliance officers handling disclosure requests
Organisations responding to information requests under data protection legislation frequently handle documents containing third-party personal data. Uploading those documents to a third-party processor creates a secondary processing activity that needs its own legal basis and documentation. Several compliance teams have found it cleaner to use a tool that does not create that dependency. Our disclosure and redaction guide covers the workflow in detail.
Small businesses and sole practitioners on tight budgets
A sole-trader accountant processing around 10 client files a month found Redactable's document cap frustrating at year-end when workload spikes. Moving to a tool without per-document limits removed the cost unpredictability. Free tier access with no cap on pattern-based detection covered straightforward redaction; the Core plan handled the rest. The switch was about economics as much as privacy architecture.
The Practical Decision
Redactable is well-suited for teams that need real-time collaborative review - simultaneous editing, threaded comments, role-based permissions, and shared project folders are genuine features built for organisations where multiple people work through the same document together. Their SOC 2 Type II and HIPAA certifications carry weight with enterprise procurement. If your organisation permits cloud processing and needs collaborative annotation across a team, Redactable is a reasonable choice.
If your documents must stay on-device, your data governance policy restricts third-party processing, you need cryptographic verification for audit purposes, or per-document pricing does not fit your workload - those are the specific constraints RedactProof was designed around.
Why Choose RedactProof over Redactable
The features that set RedactProof apart for secure document redaction.
Your Documents Stay on Your Device
Redactable requires uploading files to their AWS infrastructure before any processing begins. For an HR manager handling grievance files, a compliance officer responding to a SAR, or an accountant processing client returns - sensitive personal data travels to and sits on a third-party server. RedactProof's standard engine processes documents in the browser. The file does not leave your machine because the architecture does not send it.
Cryptographic Tamper Detection
Redactable generates a Certificate of Completion recording who redacted what and when. That is an activity log. RedactProof takes a different approach: each export carries an Ed25519 digital signature tied to the document's exact content. Modify a single character after export and verification fails. One records what was done. The other detects whether the result has been altered - which is the relevant question when demonstrating document integrity to a regulator or recipient.
No Per-Document Limits
At the time of writing (May 2026), Redactable's Starter plan covers 15 documents a month. Pro Plus covers 150. RedactProof's free tier has no document limit for pattern-based recognition. Paid tiers add AI detection without per-document quotas. Process as many files as the job requires without monitoring a counter or calculating overage costs.
Where Redactable Has the Edge
Redactable's standout feature is real-time document collaboration - multiple reviewers on the same document simultaneously, with threaded comments, @mentions, and role-based permissions. Their SOC 2 Type II and HIPAA certifications carry real weight with enterprise procurement teams. If your organisation permits cloud processing and needs several people co-editing redaction annotations together, Redactable was built for that workflow.
Common Questions
What people ask when comparing Redactable and RedactProof.
What is the main difference between RedactProof and Redactable?
Where documents are processed. Redactable is a cloud SaaS platform - your files are uploaded to their servers where AI redaction runs. RedactProof processes documents locally in your browser. Both detect personal data automatically, but the privacy model is fundamentally different. If your data handling policy restricts sending documents to third-party processors, that distinction narrows the choice considerably.
Is RedactProof cheaper than Redactable?
At the time of writing (May 2026), Redactable's Starter plan is $19/month for 15 documents, and Pro Plus is $99/month (or $79/month on annual billing) for 150 documents. RedactProof's Core plan is £19/month with no per-document limits. For anyone regularly processing more than 15 documents a month, the document caps on Redactable's lower tiers push the effective monthly cost up. The comparison depends on your volume and currency.
Does Redactable upload my files?
Yes. Redactable is cloud-native - documents must be uploaded to their AWS infrastructure before any processing occurs. The platform encrypts files with AES-256 at rest and TLS 1.2+ in transit, and holds SOC 2 Type II certification. The upload is a structural requirement, not a configuration option. If your data governance policy restricts sending sensitive documents to third-party cloud platforms, that is worth confirming before trialling.
Can I use Redactable offline?
No. Redactable's architecture is cloud-native - every document must be uploaded to their servers for processing. There is no offline mode, local processing option, or client-side fallback. If your documents cannot leave your device - common in healthcare, HR, government, and regulated financial services - Redactable is not designed for that constraint. RedactProof's standard engine processes documents entirely in the browser and works without sending document data to any external server.
Which tool is better for GDPR compliance?
Neither tool guarantees GDPR compliance - that depends on your organisation's full data handling practices. The architectural difference is relevant though. Using Redactable to process documents containing personal data creates a third-party processing relationship, which under GDPR typically requires a Data Processing Agreement, an entry in your Record of Processing Activities, and potentially a Data Protection Impact Assessment. RedactProof's standard engine processes documents in your browser without sending data to external servers, reducing the number of processing relationships to document. Consult your legal team or DPO for advice specific to your organisation.
Does Redactable offer AI-powered PII detection?
Yes. At the time of writing (May 2026), Redactable uses AI to detect common personal data types - names, email addresses, Social Security numbers, physical addresses, phone numbers, and similar. Detection runs on their servers as part of the upload-and-process workflow. RedactProof detects 60+ entity types using a model that runs locally in the browser, with confidence scoring on each suggestion.
What happens to my documents after processing in Redactable?
Redactable stores documents encrypted at rest on AWS infrastructure. Their data retention and deletion policies should be confirmed in their current Privacy Policy and any Data Processing Agreement before you process sensitive documents. For organisations where data residency matters - such as those subject to UK GDPR requirements around processing outside the UK or EEA - US-based cloud storage is worth reviewing against your own obligations.
