Pumble

The pitch that keeps coming up in Pumble's own user reviews is message history: unlike some rivals, older messages and files stay searchable rather than disappearing behind a retention cap. Around that sit the usual building blocks of a work chat tool — 1-on-1 and group messages, topic channels, threads spun off individual messages, file sharing, and mentions and notifications you can mute.

Calls, async messages and outside guests

Video conferencing and voice calls start from the chat, with screen sharing and meeting links you can send to anyone. External guests can join a meeting without a Pumble account, and guest roles give limited workspace access to clients or partners. For things that do not need a meeting, there are voice notes, recorded video messages and scheduled sending.

Admins get channel and workspace permissions plus an analytics dashboard covering how the team actually uses the tool. Pumble integrates with Clockify, Plaky, Google Drive and other apps via a marketplace, and ships an MCP server so AI agents can summarise conversations, locate files or post updates. Apps are available for Mac, Windows, Linux, iOS, Android and the browser.
