Hi Product Hunt! We built 55Chat because we were tired of messaging apps that trade your privacy for features. Our goal was simple: create an IM tool that's both secure AND actually pleasant to use daily. What makes us different: - AI smart replies that genuinely save time (not gimmicky) - True multi-device sync - start on phone, continue on desktop seamlessly - Zero data collection. Your messages stay yours. We'd love to hear your feedback on what features matter most to you in a messaging app!

How does the end-to-end encryption hold up if you're syncing across multiple devices — is each device storing its own key, and what happens if I lose access to one?

the drag-and-drop for 100MB files is way smoother than i expected, sent a video to my coworker in seconds. loving the dark mode too
