Signature Blocker

Cut the fluff from Gmail threads: collapse repeated signatures, logos, legal disclaimers and quoted replies.

Tired of scrolling past the same giant signature over and over in every reply? Signature Blocker cleans up Gmail threads so you see the messages, not the fluff: ✂ Signatures: names, titles, phone numbers, addresses, "Book a meeting" badges ✂ Logos, banners and social icons ✂ Legal and confidentiality disclaimers ✂ Quoted reply chains ("On Tue, … wrote:") ✂ "Sent from my iPhone" lines Nothing is deleted. Each block collapses into a small pill, and one click brings it back. • Private by design: detection runs entirely in your browser. No servers, no tracking, no account. • Works with signatures from Gmail, Outlook, Apple Mail, HubSpot, mobile apps and more. • Choose what gets collapsed and how aggressive it is. • Whitelist senders whose signatures you always want to see. • Optional AI assist for unusual signatures, using your own OpenAI API key (off by default, daily spending cap).
