Can you vibecode this?

Yes

Gmail OAuth + API calls to scan and delete emails, an LLM or rule-based classifier to categorise clutter, Stripe for payments, and a scheduler for automatic sweeps — all standard buildable code. Nothing here requires a licence, catalogue, or human labour.

Why people pay Mail Sweeper

Mail Sweeper has processed 8.3 million emails and built history across 3,482 connected Gmail accounts. A fresh copy starts with no cleanup history, no learned patterns, and no CASA certification that signals trust to cautious users sharing inbox access.

Product complexity
Low
A web app with AI categorization, bulk actions and scheduled sweeps is standard to build.
Data
Low
All data comes from the user's own Gmail account via Google's API; no external dataset needed.
Integrations & infrastructure
Moderate
Gmail API access requires Google OAuth and a verified app review before going live.
Human operations
Low
Scheduled sweeps run automatically in the background with no human intervention required.
Regulation / hardware
Low
CASA certification is a one-time security audit the founder completes before launch.

build-spec.txt

Build a web app that connects to a user's Gmail account and automatically cleans, unsubscribes and organizes their inbox, sold as a one-time lifetime purchase or annual subscription.

Product:
- Google OAuth login so users connect their Gmail account securely
- Inbox scanner that identifies old promotions, social updates, newsletters and large attachments
- Bulk-delete action that moves selected email categories to trash in one step
- One-click unsubscribe that surfaces every mailing list and sends opt-out requests
- Smart labeling that routes incoming clutter to a Dustpan folder, leaving the primary inbox untouched
- Scheduled automatic sweeps that periodically trash Dustpan emails older than a chosen threshold
- Customer dashboard showing emails cleaned, space saved, unsubscribes sent and carbon impact
- Starred and important emails are always excluded from any sweep or deletion

Billing:
- Lifetime one-time payment, annual personal subscription, or annual family plan (up to 5 inboxes) charged with Stripe

Integrations:
- Gmail API connected through Google OAuth using the customer's own Google credentials
