What you get

Claude-powered

Smart classification

AI reads the full email body — not just subject lines. Context, tone, sender history, and thread depth all factor into the decision.

Works with Gmail

Connect your Google account via OAuth. No IMAP passwords, no app-specific credentials — just one click and you're live.

Configurable

Custom rules

Override AI decisions any time. Pin senders as always-important, auto-archive entire domains, or block keywords before they hit your inbox.

Daily digest

One summary email each morning: what came in, what needs your attention, and what was quietly handled for you.

Classify anything, programmatically

~ curl api.inboxsentinel.app/classify
{
  "email_id": "msg_8f3a2b",
  "from": "[email protected]",
  "subject": "Re: Proposal feedback",
  "classification": "important",
  "confidence": 0.97,
  "reasoning": "Direct reply to active thread, contains action items",
  "labels": ["client", "action-required"]
}

Simple. No surprises.
