Join the first Whatnot sellers to access LeLiveBoost. Open beta July 2026.
Detect sizes in real time, manage your queue, track your buyers, and analyze your lives.
Everything you need to sell more on Whatnot.
Every live without the right tools is money left on the table.
The chat moves too fast. You miss the "W32 please" comments and the buyer goes to a competitor.
You don't know who your best customers are, what they've already bought, or their usual sizes.
No post-stream analytics. No correlation between your audience and your sales. You're flying blind.
Contacting every buyer manually, copy-pasting the same messages, handling follow-ups. A total nightmare.
LeLiveBoost installs as a Chrome extension and connects directly to your Whatnot stream.
The algorithm automatically detects jeans (W28-W40), tops (XS to 4XL), in French and English. No request slips through ever again.
Automatic priorities, VIP buyers at the top of the list. Reply in one click with the right @ and the right size. Regular vs. VIP buyer tiers built in.
Every buyer gets a profile: purchase history, sizes, total spend, personal notes. Auto-filled during your lives. Export your buyers list anytime.
Full report after every live: audience peaks, sales vs. engagement correlations, "why did this live flop?" insights. Get better every session.
Personalized post-live follow-ups, server-side, anti-detection. Your buyers get the right message at the right time. Custom message templates on Pro+.
VIP badges, spending tiers, exclusive perks. Turn occasional buyers into loyal repeat customers. Restock notifications for your top fans.
Real-time viewer counters, category heatmaps, alerts when a competitor starts a live in your niche. Spy Live = stealth viewing with full analytics. Expert plan only.
Automatic engagement prompts, giveaway management, Show Prep Assistant to plan your live. Built-in soundboard: pre-loaded clips (air horn, crowd cheer, "Sold!", countdown) plus record your own custom voice clips.
Add LeLiveBoost to Chrome in one click. Connect your Whatnot account. No complex setup required.
The LeLiveBoost panel opens automatically. Size detection active, queue ready, CRM connected. Pro Live mode gives you full control: size detection, smart queue, and live assistant all on.
No request missed. Your buyers feel seen. Your analytics guide you. Every live is better than the last.
Start for free, level up when you're ready.

No. LeLiveBoost works as a browser extension that reads the Whatnot interface. DM campaigns are server-side with anti-detection protections. We closely follow Whatnot's ToS and adapt continuously.
Yes. The algorithm detects French formats ("taille 42", "je fais du M", "W32") and English formats ("size medium", "W34L32", "XL please"). Anything that looks like a size, even with typos.
