Backstage Sidekick

Backstage Sidekick is a free moderator tool for Whatnot live shows, for iPhone and iPad. For Whatnot mods, co-hosts and sellers, it puts a mod's whole night on one tap: chat phrases, sizes and emoji, a list of everyone to thank for raids, tips and giveaway wins, prebid alerts, a name list and raid train lineups. No account, no sign-up, no charge. Anyone who's modded a show knows the loop. Welcome people in, push the follow, hype the giveaway, ask the winner's size, thank the raid. The same twenty messages, typed over and over, all night. Open your show inside Sidekick and it turns them into taps. CHAT PHRASES, IN YOUR WORDS It comes loaded with the lines mods actually post: welcomes, follow and bookmark pushes, giveaway hype, congrats, prebid and Buy It Now callouts, sponsor thank-yous. Edit any phrase, add your own categories, and fold a category away when you don't need it. Fill-in-the-blank phrases ask for the username or item, then post clean. Export your phrases to a file and bring them back in anytime. SIZES, BRANDS AND EMOJI Size chips post "sz 8" style callouts, with separate tabs for women's, men's, kids and shoes, and a brands list you fill in yourself. Pin your favorites to the top. Emoji walls land with one tap, and taps stack, so "Welcome in!" plus a heart builds one message before you send. WHO TO THANK, SO NOBODY SLIPS PAST While the show is open, Sidekick keeps a running list of the moments that deserve a shoutout: raids, tips and giveaway winners, in the order they arrived, with a clock showing who's been waiting. Thank each one by @username with a tap and check them off. Opened Sidekick mid-show? Tap Catch up to fill in what you missed. PREBID ALERTS The listings getting bids before they go live are the show's hottest items. Sidekick gives them their own tab, so one tap drops a "prebids are hot" line for the item heating up. NAME LIST Keep a running list: giveaway entries, everyone who typed DONE, people to follow back. Add names one at a time or in bulk, jot a note under anyone, or set a watch word and Sidekick collects anyone who types it in chat. Check people off, then post the whole list back to chat at once. SEE THE SHOW YOUR WAY ON IPHONE On iPhone, switch between Whatnot's phone layout, a view of just the video, or just the chat, and lock it so it stays put while you mod. RAID TRAINS Modding a raid train? Paste the train's tracking number from Raid Train Express and the Train tab shows the full running order, who's live now and who's next, with the host, the show notes and the rules, so the handoff never catches you off guard. Backstage partners with Raid Train Express, where trains are organized. WORKS THE WAY YOU MOD Pick how a tap works: Send posts straight to chat, Copy puts the phrase on your clipboard, and Build adds it to a scratch pad so you can put one message together and send it yourself. Mods and hosts can send any line as an /announce or /hide, and every phrase wears the color of what a tap will do. YOUR PRIVACY No account, no sign-up. Who bought what, who won, who tipped and how much stays on your device and is never sent to us. To learn what helps, Sidekick records the shows you work with it open: whose show it was, your Whatnot username, whether you were the seller or a mod, and counts of which features you used, along with your email if you give one. Never a buyer's name, an item, an amount of money, or anything you type in chat. We never sell your data or run ads. You sign in to Whatnot directly with Whatnot; Sidekick never sees your password.
