Your email isn't read anymore.
It's summarized.
Apple Intelligence, Gmail Gemini, and Outlook Copilot collapse every email into a 1–2 sentence glance before a human ever sees it. The Glance shows you which sentence — and lets you fix it before you send.

Why us · the moat
PanelSynth + Brand Receipts already do the hard parts.
PanelSynth already runs synthetic personas at scale. We use the same persona contract — reactions to your AI summary come from the same engine that powers PanelSynth panels.
Brand Receipts already scores how AI represents your content on the web. The Glance is the same muscle, applied to the inbox surface.
Marketing Hacked teardowns become viral content: "We ran your last newsletter through Apple Intelligence — here's what 100M iPhone users actually saw."
Companion surface · GEO
The inbox glance has a twin: the AI search glance.
The same compression that summarizes your email summarizes your brand in ChatGPT, Perplexity, and Gemini. Here's a live snapshot from Brand Receipts.
