LeLiveBoost is a Chrome extension and sales optimization platform built specifically for sellers on Whatnot. It helps live sellers manage fast-moving chats, understand their buyers, automate repetitive tasks, and analyze the performance of their streams. Instead of manually tracking buyer requests and trying to remember customer details during a busy live session, sellers can use LeLiveBoost as an AI-powered assistant working alongside them in real time.
Never Miss a Buyer Request
One of LeLiveBoost’s core features is AI-powered size detection. During a Whatnot live, buyers frequently post their preferred sizes directly in the chat. When hundreds of messages are moving quickly, these comments can easily disappear before the seller notices them.
LeLiveBoost automatically detects size requests and organizes them into a smart waiting list. It can recognize different formats, including common clothing and jeans sizes, while handling typos and messages written in English, French, and German. This allows sellers to focus more on presenting products and interacting with viewers rather than constantly scanning the chat.
Smart Buyer Queue and CRM
LeLiveBoost also helps sellers identify their most valuable customers. Its Smart VIP Queue can prioritize repeat buyers and high-spending customers, while the built-in Buyer CRM collects useful information over time.
Purchase history, customer sizes, and total spending can be associated with individual buyers, giving sellers more context about the people regularly joining their streams. This can make future interactions more personalized and help turn occasional customers into repeat buyers.
Understand What Happens After Every Live
Instead of finishing a stream with little information about why it performed well or poorly, LeLiveBoost provides post-live analytics.
Sellers can review metrics such as revenue, conversion rate, peak viewers, top buyers, and size distribution. These insights make it easier to compare streams, recognize patterns, and understand which strategies are producing the best results.
Automate Buyer Communication
Following up with viewers manually can take hours, particularly for sellers with larger audiences. LeLiveBoost includes automated DM campaigns designed to reduce this repetitive work.
Sellers can create personalized campaigns, target different categories or countries, and A/B test messages. Additional live tools include quick messages, loyalty rewards, and a customizable soundboard for keeping streams interactive and engaging.
Competitor Analytics with Spy Live
LeLiveBoost also includes Spy Live, a competitive research feature that lets sellers analyze other Whatnot live streams. It provides information such as viewer activity, engagement, and other live performance data, helping sellers understand what is working elsewhere in their niche.
Who Is LeLiveBoost For?
LeLiveBoost is designed for Whatnot sellers who want to run more organized, data-driven live selling sessions. It can be particularly useful for fashion, vintage, streetwear, collectibles, and other sellers managing frequent buyer interactions during live streams.
The platform combines AI size detection, smart queues, customer management, automated messaging, analytics, loyalty features, competitor research, and live engagement tools in a single Chrome extension. There is also a free plan, making it possible for new sellers to test the core functionality before upgrading.
In short, LeLiveBoost turns the normally chaotic process of managing a Whatnot live into a more structured workflow, helping sellers spend less time on repetitive administration and more time engaging their audience and selling products.
