Communication
Choose a place for the conversations that matter. Compare who you need to reach, how groups work and which privacy controls fit the conversation.
Zoom Workplace
Zoom Workplace combines meetings with chat, documents, and other collaboration tools.
LINE
LINE combines messaging, voice and video calls, stickers, and access across several device types.
WhatsApp Messenger
WhatsApp combines personal messages, groups, and calls.
Signal Private Messenger
A strong fit for conversations that can move together, with a migration question more important than the feature list.
Microsoft Teams
Microsoft Teams combines meetings, messages, files, and planning tools.
Rakuten Viber Messenger
A messenger for personal calls and group communication, best evaluated through contact availability, group organization, privacy settings and the boundaries of international calling.
Messenger
A communication app for familiar contacts and group coordination, with useful shared-media tools that still require clear agreements about files, corrections and audience.
Telegram
A messaging platform for conversations, communities and device continuity, with important distinctions between chat modes, account access and third-party bots.
Proton Mail
Encrypted mail and inbox organization are only part of the decision when an address also controls access to your other accounts.
How to choose in this category
Begin with the people you need to reach. A small private group, a public community and a work meeting have different requirements, even when each app can send a message. Decide whether the conversation needs to be searchable later, who controls membership and what happens when someone changes devices.
Read the individual analyses for the limits of each approach. Privacy features should be considered alongside notification visibility, account access and the behavior of participants. Moving a conversation is a shared decision; a technically capable messenger is less useful if important participants cannot join.
