Chat, calls, notes, and AI agents around a shared brain that learns. Every AI, one team. Lydo is a modern messaging app for people, teams, communities, and AI agents. Start a DM, spin up a group chat, build a Space for your circle, or run a Team Space with channels, roles, calls, notes, boards, events, and a shared knowledge vault. Your conversations stay connected to the people, files, and agents that help you act on them, so context never gets lost between apps. AI that lives in your conversations, not in a separate app. Add an agent right inside a chat or Space and it works in the same thread. Bring the models you already use, like Claude, ChatGPT, Gemini, and Grok, or use the built-in one. Give an agent the context it needs and it answers questions, searches your shared knowledge, summarizes calls, brainstorms, and helps move work forward. Every AI, one team. Your shared brain, and it learns. Ask your Space anything and get an answer drawn from your team's notes, threads, and decisions, with sources you can open. Turn a standout conversation into saved, searchable knowledge once a teammate approves it, and connect the tools your team already uses so answers stay current. Teach it once, and it keeps getting smarter as your team works. What you can do: • Create Spaces for friends, communities, study groups, creators, and projects • Run Team Spaces for work, operations, events, and collaboration • Chat in DMs, group chats, channels, and threads • Send reactions, voice notes, attachments, polls, and rich link previews • Start voice and video calls with a clean pre-call lobby, screen sharing, and live audio Stage channels • Get call notes automatically: summaries, key topics, decisions, and action items you can check off • Capture voice memos that turn into searchable notes • Write linked notes with folders, templates, and beautiful share pages • Tag AI agents into any chat or Space so help happens right in the thread • Ask your shared knowledge a question and get answers with sources • Organize Spaces with channels, categories, roles, permissions, events, boards, wiki pages, and a shared knowledge vault • Discover people and Spaces, build your profile, and invite your circle Why Lydo: Most tools split your day across chat, calls, docs, tasks, and separate AI apps. Lydo brings them together around a shared brain that gets smarter as your team works. When your messages, calls, notes, and agents share one home, context follows the work instead of getting lost between apps. Privacy and control: You decide who sees and does what, with granular roles, channel permissions, and visibility settings for every conversation and Space. Tap Confidential to erase a message from your devices and our servers, or set messages to vanish on a timer. Built for friends, teams, creators, communities, and growing organizations that want conversations with more context and less app-switching. The whole team joins free.
