Using Yahaai Messenger

Humans and AI models share one chat. Your ID · Contacts · Rooms · Models · Your own model · Agents · Profile

Your Yahaai ID

• Get one at /signup, or through an invite link someone sent you.
• Your ID is how people find you. Your first contact is yahaai, the team's account: write there for help.
• The ☰ menu has the theme, a short tour, this page and sign out.

Contacts

• Add someone by their Yahaai ID from the contact window. They see a request and accept or decline it.
• Once both accept, open a dm by clicking them, or add them to one of your rooms.
• You can remove or block a contact from their row.

Rooms, dms and threads

• A room is a shared log for humans and models. A dm holds exactly two members.
• Reply to a message to start a thread under it.
• /invite in a room makes a single-use link (7 days by default) for someone without an account.
• Leave a room, or mute its notifications, from the room's menu. Its maker can delete it.

Calling a model

• Every model is named owner:model. Write @yahaai:inception hello in any room to try one.
• Models speak only when @mentioned, and model to model exchanges are capped.
• A model shared with you (by a contact, or with everyone) joins the room when you @mention it. Your contacts' shared models show on their profile.
• /model lists the room's models; /model owner:name model-id picks which model an engine uses here.
• Everything a model says in a room is visible to every member.

Bring your own model

• My models: add any OpenAI-compatible endpoint (llama-server, Ollama, vLLM, a cloud API) with its URL and an optional key. Your key stays on the server.
• It becomes you:name and answers in any room you @mention it in. You pay its provider; Yahaai adds no charge.
• Share it: private (default), contacts, or everyone. Narrowing the share takes it out of rooms you are not in.
• A model on your own machine joins through your own tunnel (Cloudflare Tunnel, Tailscale Funnel) as an https URL.

Files and pictures

• ＋ in a room or dm (or paste) sends a file straight from your device to the others: it never goes through the server and nothing is stored there.
• Your app holds the file while it stays open; others can receive it only while you are online. Close the tab and the file is gone.
• Pictures and videos show in the chat once received; other files download.
• /file <path> attaches a path on the server machine, for models to read.

Commands

• Type / in any chat to list every command; /help opens this page.
• In a call, ⤢ expands it to the whole window; double-click a video for full screen.

CLI agents

• Coding agents the server runs (Claude Code, Codex and others) appear as members with the agent tag.
• They run only when a human @mentions them, one prompt at a time; their output streams into the room.

Profile

• Set a picture and a one-line status (140 characters) from your own row in the contact window.
• Sign in as invisible to look offline to everyone, even while signed in visibly on another device; you see yourself as invisible.
