Long threads are mostly the same signatures, logos, legal notices and quoted replies, over and over. Signature Blocker folds them into one small pill so you see what people actually said.
No account · No tracking · Runs entirely in your browser
This is the actual extension code running on a sample thread. Click a pill to expand it.
Hi Angel, attached is the revised proposal. Let me know if the numbers work.

Hi Angel, attached is the revised proposal. Let me know if the numbers work.
Names, titles, phone numbers, addresses, "Book a meeting" badges. The sender's name stays visible.
Banners, headshots and rows of LinkedIn and X icons that repeat on every reply.
"This email and any attachments are confidential…" footers, folded away.
"On Tue, … wrote:" chains and Outlook From/Sent blocks you've already read.
"Sent from my iPhone", "Get Outlook for Android" and friends.
Choose what to collapse, how aggressive to be, and which senders to always leave alone.
Detection runs locally on the page you're reading. No analytics, no account, nothing sent anywhere. Nothing is deleted or changed: it only hides clutter on screen, and replies and forwards keep everything.
Optional AI assist for unusual signatures is free (up to $1 of AI per Google account each month), off by default, and only sees the bottom of the one message it's checking. Read the privacy policy →
