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.

Say something…

Run your show. It runs the pins.

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

Golden audio waveform turning speech into shoe sizes — PinSizes hears sizes called on a Whatnot live
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 already typed

It's sitting in your chat box before you finish the call-out, updating as you go. Half sizes, 9.5 men's / 11 women's combos, youth sizes — written out 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. Forget the word? Once the chant confirms the size, it posts itself.

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, and your trigger word is the one thing PinSizes listens hardest for. It basically doesn't miss.

It gets it right, show after show

Everything in PinSizes was tuned on real lives — fast sellers, loud rooms, flash bids. If you run your own show, this is your auto-mod.

💳

Failed payments, chased for you

It re-checks your Sold list every few minutes and @'s any buyer whose payment failed, with your message — once per buyer, never spamming, silent the moment they fix it. That's real money you'd otherwise chase by hand.

🔁

Promos on autopilot

Your promo lines — share reminders, giveaway hype, bundle deals — post themselves in the dead air after each sale, spaced out so chat never feels spammed. Or tap one from the popup any time.

🎒

Not just sizes

Backpacks, sock packs, beanies — call the item and PinSizes pins your words ("Brand New Nike Backpack"), size or no size, so every auction gets its pin.

🧠

It hears it right

"Menu" means men's, "hormones" means women's, "tail" means ten. PinSizes learned from hundreds of hours of real shows — fast patter, music, auction chants — so every item gets one clean pin, never a re-post.

📌

Questions, answered

What do I need to run PinSizes?

Google Chrome (142 or newer) on a computer, and a Whatnot show you host. That’s it — the 2-minute setup wizard handles everything else. The listening is Chrome’s own built-in voice engine — no account, no key, nothing to pay for.

I go live from my phone — will this still work?

Yes — plenty of hosts do exactly this. Your phone stays the camera; you just keep a computer nearby with your show open at whatnot.com in Chrome. PinSizes listens to the show through that tab and pins into that chat, while you run the show the way you always have.

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.

Will this cause problems with my Whatnot account?

PinSizes doesn’t run a bot account, doesn’t touch bids or purchases, and nothing joins your show. It runs in your own browser, on your own login, and posts in your own chat — the exact same pin a mod sitting at your keyboard would type. It’s your pin, in your chat, on your show.

How do I pin sizes on Whatnot?

On Whatnot, hosts and moderators pin a message with the /announce command — type "/announce Size 9.5 Men’s" in chat and it stays highlighted at the top. PinSizes does the whole thing for you: it hears the size in your voice, writes the pin, and posts it the moment you say your trigger word.

Does PinSizes work for clothing and apparel sellers?

Yes — alongside shoe sizes (men’s, women’s, youth, toddler, halves, wides, grade school) it catches clothing letters like S, M, L, XL, 2XL/3XL and toddler apparel sizes 2T–5T. And for things with no size at all — a backpack, a sock pack — it pins the item you call out.

Can it chase failed payments?

Yes. PinSizes re-checks your show’s Sold list every few minutes and posts a chat message @-ing any buyer whose payment failed, using a message you write. A brand-new failure gets about five minutes of grace first. Each buyer is messaged once per failure — no spam — and the reminders stop the moment their payment goes through.

What does the listening run on?

Chrome’s own built-in voice engine, running right on your computer. There’s no account to create, no key to paste and no per-hour cost, ever — and because the speech-to-text happens on your machine, your show audio never leaves your browser. The setup wizard installs Chrome’s English voice pack with one click.

Does my audio go through your servers?

Never. Audio goes from your browser straight to the voice service under your own account. Our server only checks your license.

What’s the bar Chrome shows when I press Start?

Totally normal — that bar is Chrome letting you know PinSizes is allowed to type into your chat for you. It appears when you press Start, goes away when you stop, and your viewers can never see it — it’s part of your browser, not your stream. Leave it open during the show; closing it turns the typing off.

How do I cancel?

In your PayPal account, under automatic payments — one click, no email required. You keep access until the end of the paid period.
