Every redaction tool asks you to upload sensitive documents somewhere. ZeroEgress is the only one that doesn't. Here's the full comparison.
Documents leave your device and are processed on Redactable's servers. Requires SOC 2 and HIPAA trust chain. From $19/month or $7.50/doc.
Extracts text in the browser, then sends it to Anthropic's Claude API for classification. Text leaves your device. From $29/month.
AI model runs locally via WebAssembly. Documents, text, and results never leave the browser. Verify with DevTools → Network. Free.

Redactable uploads your document to their cloud. SafeRedact extracts text and sends it to Anthropic's API. ZeroEgress runs the entire AI pipeline — NER model, encryption, memory clearing — inside your browser. Open DevTools → Network tab during processing. You'll see zero outbound requests. That's the proof.
SafeRedact uses "pixel-burn" — rendering each page as a new image. The original text is gone, but the output is likely not searchable or accessible to screen readers. ZeroEgress generates a completely new document with redacted text. The original text is never in the output — but the result is real, searchable, accessible text.
Redactable needs you to trust their servers, their SOC 2 auditor, their encryption, their employees. SafeRedact needs you to trust Anthropic's zero-retention policy. ZeroEgress needs you to trust your browser. And you can verify it yourself — the code runs in front of you.
Redactable has team collaboration, integrations with Clio and Google Drive, and SOC 2 Type II certification. If you need 10 people working on the same document with audit trails and enterprise workflows — Redactable is built for that. ZeroEgress is built for the case where documents can't leave your network. Different problem, different tool.
Drop a document. Watch the Network tab. Nothing leaves.
