imo vs Jami

imo is a communication app for internet calls and messaging, available on Android, iOS, macOS, web, and Windows. It offers HD audio and video calls, including international calls, and group video calls for up to 20 participants with no fixed time limit. Chats support real-time messages, photos, videos, voice recordings, and group conversations; its Big Group feature supports up to 5,000 members. Stories hold photos, videos, and text updates for 24 hours. Listed privacy features include end-to-end encryption, Time Machine, and disappearing messages, while account controls include two-step verification and spam blocking. Encryption coverage is mixed. Instant message translation is available, and the privacy policy says Google Translate may provide it. That policy also says imo collects usage data, including communication partners, times, and message content. On iOS, imo integrates with Siri and can access iCloud Drive for file sharing. The app is free, though mobile carrier data charges may apply to internet calls.

Jami is free/libre software for private messaging and calls, with end-to-end encrypted communications and peer-to-peer connections. It offers instant messaging, audio and video calls, group chats, and recorded audio and video messages. Users can hold video conferences and create rendezvous points without third-party hosting, as well as share files or screens and stream media. Jami says it does not require a server to relay data between users; it also states that communications use perfect forward secrecy and comply with the X.509 standard. One account can link multiple devices, and account creation does not require personal information. Jami can also function as a regular SIP client. Optional extensions include green screen, watermark, auto answer, local AI transcription, audio filter, and video segmentation. These extensions are unavailable to iOS users, and features vary by client. Platforms listed include Android, iOS, Linux, macOS, web, and Windows, along with API and extension access. Jami also provides an OpenClaw channel plugin; bot accounts and API access are supported on desktop Linux, macOS, and Windows. The project is led by Savoir-faire Linux Inc. and supported by a global community of free software contributors.
