The first inbox you don't just use. You own it, shape it, and program it.
Sandboxed. Not another tab. Use what others built, or write your own.
Swap the black box for logic you trust.
Teach it what actually matters to you.
Auto-files receipts as they arrive.
Manage customers where they email you.
Run your stack on email, not glue.
Opt in, opt out. We never train on your mail.
Every app is sandboxed. Every action is reviewed.
Every app runs isolated. No ambient access to your data or the network.
No action fires directly. Each is reviewed and auditable before it touches your mail.
Every app declares its capabilities up front. Whatever it doesn't request, it can't do.
Never pooled across users. Bring your own domain. No lock-in, no landlord.

It reads your mail and classifies transactions into a spending summary. Apps can only reach safe, secure endpoints on the internet that Twing allows.
Every attachment becomes a real, searchable file. Never again buried in a thread you'll never reopen.
Keep your current inbox running while Twing becomes your primary. Zero migration.
