Can AI replace Gmelius?

Do not mistake the interface for the product. Gmelius's durable value is deliverability, security, integration, which a solo one-shot build cannot reproduce responsibly. The prompt therefore builds only the closest honest personal consolation tool.

PlanMonthlyBilled yearlyWhat you get
Meli$21$19/moUp to 5 users; 5,000 email conversations/month; 5 custom AI labels.
Growth$33$25/moUp to 50 users; 10,000 email conversations/month; 10,000 rule executions/month; 10 custom AI labels.
Pro$50$40/moUnlimited users; 100,000 email conversations/month; 100,000 rule executions/month; 20 custom AI labels.
Enterprise——50-user minimum; unlimited email conversations and rule executions; 100 custom AI labels.

Hidden costs: Every connected Google/Google Workspace mailbox is a paid user, all members of one team must use the same plan, and Enterprise has a 50-user minimum; published usage caps can force an upgrade.

02Could AI build it for you?

The core job: Build a local email companion for Gmail collaboration that works on exported mail or one user-authorized IMAP account.

What a working version needs:

  • desktop development machine
  • IMAP or Gmail OAuth credentials where supported
  • secure local keychain access
  • Explicit README warning that this is a consolation build, not a production replacement

Credibility row: Gmelius survives for a structural reason, not because its interface is difficult to copy.

03What you'd give up

  • team routing and shared inbox rules
  • abuse response and security operations
  • provider-grade deliverability
  • push reliability across devices

Gmelius: Email is infrastructure. Customers pay to avoid lost messages, broken auth, spam problems, and the reputational cost of a flaky inbox.

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 the closest honest consolation tool inspired by Gmelius; do not claim to replace its structural moat.
Use exactly this stack: Tauri 2 + React + TypeScript + SQLite.
Primary job: Build a local email companion for Gmail collaboration that works on exported mail or one user-authorized IMAP account.
Start from an empty folder and create the complete working project.
Make the default mode single-user and private.
Store user data locally unless the core job requires the declared self-hosted database.
Do not add analytics, telemetry, ads, or third-party accounts.
Put every secret and external credential in .env and provide .env.example.
Use realistic sample data that is clearly labelled and easy to delete.
Implement the smallest polished interface that completes the core loop end to end.
Include clear empty, loading, validation, success, and failure states.
Add import and export so the user is not trapped in the app.
Use accessible keyboard navigation, labels, focus states, and sensible contrast.
Validate untrusted input and never log secrets or private file contents.
Deliberately exclude these paid-product advantages: team routing and shared inbox rules; abuse response and security operations; provider-grade deliverability.
Do not fake integrations, network effects, proprietary data, model quality, compliance, or security claims.
Where an external API is optional, keep the app useful without it and explain the degraded mode.
Write focused unit tests for the data model and the most important workflow.
Add one end-to-end smoke test that proves the core loop works.
Create a README with setup, permissions, architecture, data location, backup, and limitations.
Add scripts for install, development, test, build, and a production-style local run.
Run the tests and build before finishing, then fix errors rather than merely describing them.
