Password managers, digital-legacy platforms, and cloud storage each solve part of the problem. SeraVault brings post-quantum, zero-knowledge encryption to your documents, chat, and forms — in one place.
Most tools for protecting sensitive information were built for a single job: storing passwords, holding estate paperwork, or syncing files. SeraVault is an encrypted vault for the documents that matter most — protected by ML-KEM-768 post-quantum encryption and a zero-knowledge architecture, so not even we can read your data. Here's an honest look at where each category is strong and where SeraVault is different.
A zero-knowledge promise is only as good as your ability to verify it. SeraVault's app, including its encryption, is open source and independently auditable, so security researchers and curious users alike can confirm our claims hold up. Most password managers, digital-legacy platforms, and cloud providers are closed source — you have to trust them.

SeraVault isn't a replacement for autofill — it's built for the sensitive documents, files, and records that surround those credentials, with encrypted sharing, chat, and forms alongside them.
| Capability | SeraVault | Password Managers |
|---|---|---|
| Primary purpose | Encrypted vault for documents, files & records | Storing & autofilling passwords and logins |
| Post-quantum encryptionResistant to future quantum attacks | ✓ ML-KEM-768 (NIST FIPS 203) | ✗ Classical encryption (e.g. AES / RSA) |
| Zero-knowledge architecture | ✓ Encrypted on your device before upload | ~ Many are zero-knowledge; varies by provider |
| Store & share large documents | ✓ Files, scans, PDFs, IDs, contracts | ~ Attachments only; small size limits |
| Encrypted chat | ✓ Per-file encrypted messaging | ✗ |
| Custom encrypted forms | ✓ Intake, emergency contacts, onboarding | ✗ |
| Per-recipient sharing & instant revoke | ✓ | ~ Credential sharing, varies by plan |
| Password autofill in browser | ✗ Not an autofill tool | ✓ Core strength |
| Open source & auditable | ✓ Encryption code public on GitHub | ~ Mostly closed source; varies |
Digital-legacy platforms such as Prisidio, Everplans, and Trustworthy help families organize estate documents, wills, and important records, often with sharing for an executor or next of kin. SeraVault serves the same "keep the important things safe and shareable" need, but leads with end-to-end, post-quantum encryption and gives you granular, revocable sharing over every file.
| Capability | SeraVault | Digital-Legacy Platforms |
|---|---|---|
| Primary purpose | Encrypted vault for family & business records | Organizing estate & family documents |
| Post-quantum encryption | ✓ ML-KEM-768 (NIST FIPS 203) | ✗ Classical encryption |
| Zero-knowledge architecture | ✓ Provider cannot read your files | ~ Varies; often provider-managed keys |
| Organize records by category | ✓ | ✓ Core strength |
| Emergency / trusted-person access | ✓ Family emergency vault access, revocable | ✓ Executor / next-of-kin access |
| Per-recipient sharing & instant revoke | ✓ Per-recipient encryption, one-click revoke | ~ Sharing varies by platform |
| Encrypted chat | ✓ | ✗ |
| Custom encrypted forms | ✓ Medical history, emergency contacts | ~ Some offer structured intake fields |
| Export everything, no lock-in | ✓ One-click, fully decrypted export | ~ Varies by platform |
| Open source & auditable | ✓ Encryption code public on GitHub | ✗ Closed source |
General cloud storage such as Google Drive, Dropbox, and iCloud is convenient and great for everyday files. But those files are typically encrypted with keys the provider controls, which means the provider — or anyone who compels them — can potentially access your content. SeraVault encrypts on your device first, so the provider never holds a readable copy.
| Capability | SeraVault | Cloud Storage |
|---|---|---|
| Primary purpose | Encrypted vault for sensitive files | General file storage & sync |
| Post-quantum encryption | ✓ ML-KEM-768 (NIST FIPS 203) | ✗ Classical encryption |
| Zero-knowledge by default | ✓ Provider cannot read your files | ✗ Provider-managed keys in most plans |
| Content scanning | ✓ No content scanning — can't read files | ✗ Files may be scanned / indexed |
| Per-recipient sharing & instant revoke | ✓ Per-recipient encryption | ~ Link/permission sharing |
| Encrypted chat & custom forms | ✓ | ✗ |
| Everyday storage capacity | ~ Vault for what matters most | ✓ Large capacity, cheap bulk storage |
| Export everything, no lock-in | ✓ | ✓ |
| Open source & auditable | ✓ Encryption code public on GitHub | ✗ Closed source |
