to me · just now
Quick one, can you send over the Q3 numbers before our 4pm?
ProfessionalMediumGeneral reply
Pulling them together now and will share before the call. I'll include the usual summary up top so you can skim it on the way in, and I'll flag anything that looks off from last quarter. Let me know if there's a specific cut you want me to lead with.
How it works
Three steps, about thirty seconds.
Tappy lives inside the reply boxes you already use. The rest is one tap.
02
Tap the sparkle
Open a reply box and click the small ✨ Tappy adds. No new tab, no pasting.

03
Edit and send
A draft shows up in your tone. Read it, tweak a word or two, send.
The difference
Copy-paste loop, or one tap.
Without Tappy
The tab-switching loop
Open ChatGPT, copy the thread, paste context, wait, copy the reply, switch back, paste, fix formatting.
About 6 steps. 2 to 3 minutes. 4 tab switches.
With Tappy
One tap, done.
Click the ✨ in the reply box. Draft shows up. Send.
1 step. About 5 seconds. No tab switching.
