Why I built TellPip (and what it actually does in a call)

A few of you asked how a one-person product ended up here, so here’s the backstory that didn’t fit on the launch page.

I’ve spent pretty much my whole career around sound and conversations. For years I was a PM in audio software, the tools people use to record and shape what you hear. Then I moved to voice AI that sits inside live phone calls, at scale. Thousands of conversations a day, agents getting coached while the customer was still on the line, simulated calls to train people before their first real one.

And I kept seeing the same thing. The good answer always exists somewhere, in a doc or in a colleague’s head, but it shows up five minutes too late. Honestly it happened to me too. I’d promise something to a client, three calls later I’d completely lost track of it... and the client definitely hadn’t.

That was the itch. I didn’t want another notetaker that sends you a nice summary after the damage is done. I wanted a colleague who leans over and whispers the right thing at the right second.

So I built it and tested it on hundreds of real situations: sales calls, client meetings, internal calls, interviews, in a bunch of languages. I was also helped by several friends and ex-colleagues as beta testers who I thanks a lot for their feedback.

What Pip does today:

• listens to the call right from your Mac. no bot joins, nobody sees an extra participant

• transcribes on the Mac itself, in lots of European languages, and you can teach it your clients names so it stops misspelling them

• remembers what you promised each client and reminds you the next time you talk to them

• whispers an answer when someone asks you something, using your own documents and what was said earlier in the call

• keeps a page with all your commitments and writes the notes after the call, so you dont have to

• stays invisible when you share your screen

• works with Zoom, Meet, Teams, WhatsApp, even a phone on speaker... whatever you already use

• your audio never leaves your computer. built in Europe

It went live here on 4 November and ended up #15 of the day with 85 upvotes, which I really didn’t expect. Even less all the replies from people I’d never talked to before. Thanks to all of you following along, it means a lot.
