For Whatnot hosts

Say the size.
Say the word.
It's pinned.

PinSizes listens to your live, catches every shoe and clothing size you call out, and pins it to chat the second you say your trigger word. You're the host — you don't need to hunt down a mod to pin sizes anymore.

📌 PINNED
🎙 hearing you

Run your show. It runs the pins.

Three things happen on every item, and you only do the one you're already doing: talking.

While you talk

It hears the size

"Nine and a half men's, eleven women's" — caught mid-patter, over music, through auction chants. Built and tuned on real live shows, it knows "thirty" usually means thirteen and a countdown is never a size.

Before you ask

The pin is staged

The announcement is already typed into your chat box, updating as the call-out grows. Half sizes, dual men's/women's labels, youth conversions — formatted clean, waiting on your word.

When you're ready

Your word posts it

Say "running now" — or any phrase you pick — and the size is pinned to chat that instant. Hands on the shoes, eyes on the bids, zero typing.

Pick your word.
Watch it fire.

Your trigger word is yours — whatever you already say when a run starts. Choose one and watch the show react.

In the real thing this works exactly the same way — your voice is the button. Trigger words are boosted in the speech model so a missed word is a rounding error, not a habit.

🎙 hearing you

Tuned on real shows, not demos

Every guard in PinSizes exists because something went sideways on a real live. This is the boring reliability your show deserves.

🧠

Mishearing-proof

"Menu" means men's, "hormones" means women's, "tail" means ten. A tuned alias map built from hundreds of real transcripts catches what fast patter garbles.

⏱️

Auction-aware

It knows the rhythm: sizes get called between auctions and chanted during them. One pin per item, never a re-post of the chant, never a countdown mistaken for a size.

🎯

Your word, your moment

Trigger mode posts when you say so. Prefer hands-off? Fully automatic mode posts when the auction starts. Prefer control? Manual mode stages it and your Enter sends.

📌

Real Whatnot pins

Pins go through Whatnot's own /announce, typed with real keystrokes into your chat. It works because you're the host — no bot account, no second phone, no mod favors.

💬

Quick pins

One-tap promo lines for the idle stretch — share reminders, giveaway hype, bundle deals — pinned from the popup without touching your chat box mid-thought.

🔒

Audio at cost

You plug in your own Deepgram speech key ($200 free credit ≈ 400 show hours, then ~$0.46/hr). Your audio never routes through us — we never hear your show.

One mod that never misses a show

A good mod is gold. This one shows up to every live, never gets tired at hour three, and costs less than one shipped pair a month.

Questions, answered

What do I need to run PinSizes?

Three things: Google Chrome on a computer (PinSizes is a Chrome extension, so it can't run on your phone — you host from Chrome with your show open at whatnot.com), a Whatnot show you host or moderate, and a free Deepgram account for the audio (the setup wizard walks you through it).

Do I need to be a moderator?

No — that's the point. Pins post through Whatnot's /announce command, which works for the host of the show (and mods). You host, PinSizes pins.

What exactly does "trigger word" mean?

Any phrase you choose — "running now", "start it now", anything you already say. When PinSizes hears it in your stream audio, it posts the staged size pin that instant. You can change your phrases anytime in Settings.

Why does Chrome show a "started debugging this browser" bar?

Whatnot only accepts slash commands typed with real keystrokes, and that bar is Chrome's way of saying PinSizes is doing the typing for you. It appears when you press Start and goes away when you stop. Leave it open during the show — closing it turns the typing off.

What's the Deepgram key about?

Deepgram is the speech-to-text engine. You create a free account and plug in your own key, so your audio bills at cost with no markup — new accounts get $200 of credit, roughly 400 hours of show time. Setup takes about two minutes and the extension walks you through it.

Does my audio go through your servers?

Never. Audio goes from your browser straight to Deepgram with your own key. Our server only checks your license.

How do I cancel?

In your PayPal account, under automatic payments — one click, no email required. Your key works until the end of the paid period.
