Overview

ScaiWave is a messaging and collaboration platform built around three ideas that most chat tools treat as afterthoughts:

AI is a first-class participant, not a sidebar widget. AI helpers join rooms the same way people do, follow the same conversation, and can be reasoned about as members.
Notes and conversations live in the same place, with hard distinctions about what each is for. Conversations are ephemeral threads; notes are durable documents. Both are addressable, linkable, and searchable.
Multi-tenant by design. Every workspace, every room, every message is scoped to a tenant. Federation lets tenants talk to each other across organisational boundaries without giving up that isolation.

What you can do with it#

Talk to your team in rooms — direct messages, group rooms, public rooms, and AI-only chat rooms. With emoji, reactions, threading, redaction, edits, mentions, and live typing.
Bring AI into the conversation. Engage an AI assistant the same way you'd @ a teammate. Each AI participant has its own model, system prompt, response mode, plugin loadout, and behaviour caps.
Delegate long work to sidekicks. When something will take more than thirty seconds, the AI can fan out work to background "sidekick" rooms that run in parallel and report back when done.
Plan multi-step tasks. The AI can commit to a written plan, work through it step by step, revise it mid-flight, and recover from failures. You can pause, resume, or cancel it as the supervisor.
Keep durable notes alongside the rooms they came from. Notes support wiki-style [[links]], embedded math, todo blocks that index into a cross-workspace todo system, voice transcription, and AI organisation.
Take audio and video calls in any room, with screen share, PiP, recordings, and live transcription.
Federate across tenants. Invite a participant from another organisation into your room; they show up as a real member, their messages stream in, and their actions are authenticated end-to-end.
Bridge to other chat platforms. Slack, Discord, Teams, or a remote ScaiWave — a single signed webhook protocol relays messages both ways.

Teams who want a unified surface for chat, notes, and AI assistance without juggling four tools.
Builders integrating AI into their work — ScaiWave gives the AI real conversational context, persistent memory, and the ability to use tools without leaving the chat.
Tenants needing strict isolation — every model, room, and document is scoped to a tenant, and you can federate without surrendering control.

Not a single-user notebook app. Notes are powerful, but the product centre of gravity is multi-participant rooms.
Not a video-only platform. Calls are first-class, but they belong inside rooms; there's no top-level "meetings" surface.
Not a closed system. ScaiWave speaks an open Server-to-Server protocol; you can host your own instance and federate with the ScaiLabs-hosted one.

You don't need to know any of that to use the product. You do need to know about rooms and workspaces — see Concepts next.
