HashChat (formerly Mingle) • HashChat supports all-direction interpreting and translation across 3+ languages. Even when multiple languages are mixed in the same conversation, everything is translated in real time, so you do not need to manually choose or switch languages whenever speakers change. • Get uninterrupted translation with live transcripts. Instead of stopping after each sentence, HashChat continuously translates along the full flow of your conversation or meeting, helping you follow context naturally. • See real-time captions and translations even for audio from other apps. If you run voice apps such as phone calls, radio, or Discord in the background on speakerphone while HashChat is in the foreground, that audio is captured as HashChat input and shown instantly as transcripts and translations. • Listen to translation as real-time voice interpreting. Turn on voice output to hear translated content like having an interpreter beside you, so you can understand without looking at the screen, even while running. • Keep it running in the background and switch apps freely. Even if you lock your screen or move HashChat to the background, it stays active and continues writing live conversation logs and translations. HashChat: Global Hangout
