mailtrim – find what's actually filling your Gmail inbox
I always assumed Gmail bloat came from large attachments. Turns out 3 senders were responsible for 30% of my inbox — thousands of tiny emails I'd never thought to clean up. I built mailtrim to surface this pattern: - ranks senders by actual storage impact (not just count) - confidence scoring on what's safe to bulk-delete - 30-day undo on everything — nothing is permanent by default - runs entirely locally, no email data leaves your machine Free, open source (MIT). No subscription, no backend. One friction point upfront: Gmail API setup is one-time, ~15 min. After that it's just `mailtrim…

In plain words
Mailtrim helps Gmail users identify and remove emails that consume the most storage by ranking senders by actual storage impact rather than message count. The tool is designed for anyone struggling with inbox bloat and runs entirely locally without transmitting email data to external servers. It offers confidence scoring to guide bulk deletion decisions and includes a 30-day undo feature for safety. Available as free, open-source software with no subscription required.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
