Can AI replace Proton Drive Plus?

Q: Can AI replace Proton Drive Plus?

Nah. A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Proton Drive Plus, back up files into an encrypted user-owned store and expose simple share links. The hard boundary is end-to-end encryption, proton identity, mobile apps, recovery, and privacy operations, plus reliability, durability, and cross-device sync.

01What it costs

$5.68/moDrive Plus, monthly per user

$68.16per year at that price

Checked Aug 11, 2026 · source: proton.me.

Plan	Monthly	Billed yearly	What you get
Proton Free	Free	Free	2 GB storage initially; up to 5 GB after completing onboarding actions.
Drive Plus	$5.68	$4.54/mo	200 GB storage; 10-year file-version recovery.
Proton Unlimited	$14.78	$11.37/mo	500 GB shared across Proton services for 1 user.
Proton Duo	$22.75	$17.06/mo	2 TB shared by 2 users.
Proton Family	$34.13	$27.3/mo	3 TB shared by up to 6 users.

Hidden costs: There is no Drive-only metered storage overage. Once storage is exhausted, the user must delete data or upgrade to a larger Proton bundle. Refund eligibility is generally limited to the first 30 days and subject to Proton's terms.

02Could AI build it for you?

The core job: Back up files into a user-owned object store, encrypt them client-side, track versions, restore on demand, and expose simple share links.

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 Drive Plus plan and a single-user encrypted backup DIY substitute. Recheck price before merge.

03What you'd give up

end-to-end encryption, Proton identity, mobile apps, recovery, and privacy operations
global sync network
battle-tested conflict resolution
ransomware recovery guarantees
mobile clients and support

People still pay for Proton Drive Plus 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.

prompt.txt

Build a closest honest personal substitute for Proton Drive Plus 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: back up files into a user-owned object store, encrypt them client-side, track versions, restore on demand, and expose simple share links.
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.
