Interkom is a private, end-to-end encrypted Slack alternative โ€” team chat, channels, stories, and voice notes for your company. Native iOS, macOS, and web. YOUR TEAM, WITHOUT THE NOISE - Channels keep conversations in the right rooms - Direct messages and group chats with real-time presence and typing indicators - Voice notes when typing isn't faster 24-HOUR STORIES Share moments that matter and disappear โ€” a shipped feature, a view from the office, a quick update. Workspace-only, never public. PRIVACY BY DESIGN Every message is end-to-end encrypted on your device before it leaves. Signal-grade. Default-on. We can't read your messages even if asked. Keys are generated locally, rotated continuously. New device? You verify it. Lose one? Revoke it. ENCRYPTED CALLS Audio and video calls, end-to-end encrypted like everything else. Screen share on iOS and Mac. Company-channel calls are admin-only โ€” no accidental all-hands. YOUR WORKSPACE, YOUR URL Each team gets its own home at yourcompany.interkom.app โ€” invite-only, private, scoped to your people. PER-WORKSPACE PROFILES Different name, photo, and handle at each workspace. Your startup self and your side-project self don't need to meet. BUILT NATIVE, NOT ELECTRON SwiftUI from day one. 60fps lists, real haptics, real Mac menus, every keyboard shortcut you reach for. Cold-starts in under a second. FREE PLAN THAT ACTUALLY WORKS Up to 5 teammates, full message history with no 90-day wall, channels, stories, and DMs. No credit card, no expiry. WHAT YOU'LL NEED Interkom requires iOS 18 or later and a free account at interkom.app.

Tired of retyping the same listing for Poshmark, eBay, Depop, Mercari, Facebook Marketplace, and Vinted? ListOnce is built for resellers who sell everywhere. WHAT LISTONCE DOES - Generate platform-optimized listings: enter your item once, get six ready-to-paste versions that fit each marketplace's character limits and conventions. - Track real profit, not just sales: log what you paid, your sale price, and where each item came from. See your true margin across every platform. - One public storefront at listonceapp.com/yourname: drop the link in your Instagram bio no matter which app buyers prefer. - Photo-first listings: take photos in the app or pick from your library, up to 8 photos per listing. - Per-platform fee calculator: see your actual net payout on every platform side-by-side, with the best one highlighted. - Custom brand library: type any brand, hundreds built in, new ones get added for everyone. - Real activity feed and inventory dashboard: active listings, sold count, revenue. HONEST ABOUT WHAT IT IS ListOnce is a listing assistant. We do not automatically post to platforms (they do not allow third-party posting). We generate the perfect content; you paste it over in one tap. Mark each platform as posted so we can keep your inventory accurate. DESIGNED FOR REAL RESELLERS Built by a thrift-flipping reseller, for resellers. No bloat, no fake stats, no shady automation that could get your accounts banned. PRIVACY AND CONTROL Your data stays yours. Delete your account and everything is gone instantly. We do not sell your information or use it for ads.
