Can AI replace Tresorit?

A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Tresorit, sync a small encrypted folder set to user-owned storage with secure links. The hard boundary is audited encryption, cross-platform clients, sharing policy, recovery, and compliance, plus reliability, durability, and cross-device sync.

02Could AI build it for you?

The core job: Sync and back up a small folder set, encrypt files client-side, share secure links, track versions, and restore them from user-owned object storage.

What a working version needs:

  • user-owned server or S3-compatible bucket
  • PostgreSQL
  • MinIO or object storage
  • desktop filesystem permissions
  • backup key stored offline

Editorial comparison targets the Personal plan and a single-user encrypted backup DIY substitute. Recheck price before merge.

03What you'd give up

  • audited encryption, cross-platform clients, sharing policy, recovery, and compliance
  • global sync network
  • battle-tested conflict resolution
  • ransomware recovery guarantees
  • mobile clients and support

People still pay for Tresorit because storage subscriptions sell confidence that files will still exist after a lost device, bad sync, or provider incident. The recurring cost buys chunking, encryption, conflict detection, versions, garbage collection, bandwidth, restore drills, monitoring, billing, and disaster recovery, not just the visible interface.

05The build prompt

Paste this into an AI coding tool (such as Claude, ChatGPT, Lovable or Replit) to build your own version. Read the verdict first: this one is hard to get right.

prompt.txt
Build a closest honest personal substitute for Tresorit in an empty repository.
Use Next.js 15, TypeScript, PostgreSQL, MinIO, and a Tauri 2 sync client; do not offer alternative stacks.
The core loop is: sync and back up a small folder set, encrypt files client-side, share secure links, track versions, and restore them from user-owned object storage.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Build a desktop client that watches explicitly selected folders and ignores configured patterns.
Chunk, hash, compress, and encrypt files locally before uploading to the configured object store.
Store version metadata, tombstones, device identifiers, and integrity checks in PostgreSQL.
Provide upload and restore queues with pause, retry, bandwidth limits, and resumable transfers.
Add file history, point-in-time restore, key export, storage usage, and scheduled restore tests.
Document the failure model and make clear that one server is not a complete backup strategy.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure.
Deliberately leave out multi-provider consumer sync at global scale.
Deliberately leave out guaranteed durability or ransomware recovery.
Deliberately leave out shared-drive administration, mobile apps, and enterprise compliance.
Finish by running the tests and listing the exact commands used.
