Messaging
Encrypted 1-to-1 text, delivery/read state, replies, forwarding, edits, deletes, important markers and semantic reactions.
FEATURES
One app. Several ways to communicate.
Hashi combines everyday messaging with real-time communication, local productivity tools and configurable safety controls.
Chat History Calendar
Jump directly to a specific day or date range instead of scrolling back through weeks or months of conversation history. A Return to Latest action brings you straight back to the newest messages.
Date-based Clear Chat
Clear local chat history for a selected day or date range when you do not want to erase the whole conversation. Clear All remains available when you want to remove the complete local chat history.
Encrypted media
Images, files, audio and video use authenticated encrypted transfer workflows with quality choices, retry/cancel support and progressive playback where supported.
Calls
WebRTC audio/video calls with microphone, camera, speaker and camera-flip controls plus reconnect-aware runtime behavior.
Conferences
Audio/video conferences for up to six total participants, plus scheduled conference invitations, reminders and host start/cancel flows.
Quick Discussion
Invite another participant into a temporary multi-party discussion without exposing earlier private chat history.
Walkie-Talkie
Join a radio channel in listen mode and hold Push-to-Talk only when you want to transmit.

On-device language identification and translation models downloadable inside the app.
