CallSign is group chat with AI for gaming and spending time with friends over voice, video, or text. Its Free plan includes servers, channels, direct messages, and voice channels, plus what the service calls “Always-on safety.” File uploads are limited to 25 MB on Free, 50 MB on Pro Basic, and 500 MB on Pro. Screen sharing is listed at 720p on Free, 1080p on Pro Basic, and 4K/60fps on Pro. The Pro page lists an AI assistant, summaries, voice transcription, and semantic search across messages. Pro also includes animated avatars and custom profile themes; custom emoji and stickers are included with Pro Basic and Pro. CallSign is available on Android, iOS, web, Windows, macOS, and Linux. Free costs nothing. Pro Basic is $2.99 a month or 29.99 USD yearly; Pro is $19.99 a month or 199.99 USD yearly. PlayStation and Xbox are listed as coming soon. A Public Test Build is available for trying features before launch and reporting bugs.

GGBRO is a hosted platform for gamer and community communication, combining text chat, voice, video and screen sharing. It supports web, Windows, Android and API access. Members can create unlimited servers and use replies, edits, pins, reactions, file uploads, GIFs, link previews and channel search. Voice channels use a LiveKit SFU, while direct and group calls include voice, video and screen-sharing controls. An Apps launcher provides Discovery, Gemini AI, Streamers and other apps. Developers can create bots through a REST API and Socket.IO gateway; bot creation and API use are listed as free with no usage fees. Windows plugins run in sandboxed iframes with declared permissions, and sensitive permissions require confirmation. GGBRO says passwords use bcrypt hashing, 2FA secrets are encrypted, client-server traffic uses TLS and calls use DTLS-SRTP. The Free plan costs nothing and includes core features, one server backup and 25 MB uploads.
