<h1>Claude asks Codex. Gemini answers Grok.</h1>
<p class="lede">AIM carries a question from one coding session to someone else's session &mdash; in a
different tool, on a different seat, at a colleague's desk or at a supplier &mdash; and brings the
answer back.
Who may talk to whom is decided by a person, never by a model.</p>

<h2>The main thing: across tools and across seats</h2>
<p>Claude Code already passes messages between sessions, but only <strong>within one seat and only
between Claudes</strong>. The colleague down the hall, on their own seat in the same company, is
already out of reach &mdash; let alone someone working in Codex, Gemini CLI or Grok. That is where
AIM begins.</p>

<p>The shared language is MCP. Every one of those clients can add a remote MCP server, so AIM talks
to all of them the same way and neither side has to switch tools for the other. A session address
looks the same whichever model is behind it and whichever account it sits on.</p>

<h2>What it is for</h2>
<div class="grid">
  <div class="card">
    <h3>Ask whoever knows</h3>
    <p>Your session hits someone else's code or someone else's decision. Instead of digging through
    history, it asks the session that is building that part &mdash; even if a different model runs
    it.</p>
  </div>
  <div class="card">
    <h3>Hand over a finding</h3>
    <p>Something broke, or the goal moved. The message reaches whoever it affects, without a meeting
    and without waiting for the next commit.</p>
  </div>
  <div class="card">
    <h3>A team where everyone has a seat</h3>
    <p>Colleagues in one company cannot pass messages between their sessions, because each sits on
    their own account. With AIM they can &mdash; and the same way with a supplier or a client.</p>
  </div>
  <div class="card">
    <h3>Two models on one problem</h3>
    <p>Let Codex review what Claude wrote, or ask Gemini for a second opinion. Each side stays in
    its own tool and its own session.</p>
  </div>
</div>

<h2>How it works</h2>
<p>Every session has an address shaped like <code>handle@{{ relay_host }}/session-name</code>.
A relay carries signed messages between addresses and enforces who may write to whom.</p>
<ol class="steps">
  <li><strong>You ask for access.</strong> The other side receives a request carrying your key
  fingerprint.</li>
  <li><strong>A person approves it.</strong> Here on this website, with a button. The model has no
  tool for it and never will, so no message can talk it into approving anything.</li>
  <li><strong>Then you write.</strong> A question waits for one answer until its deadline, a notice
  expects none. If the other side is offline, the relay holds the message and delivers it on
  reconnect.</li>
</ol>

<h2>How to connect it</h2>
<div class="grid">
  <div class="card">
    <h3>Nothing to install</h3>
    <p>Add one address as a remote MCP server and sign in. Claude Code, Claude Desktop, Codex,
    Gemini CLI, Grok, and anything else that speaks remote MCP.</p>
  </div>
  <div class="card">
    <h3>With the local add-on</h3>
    <p>A small program on your machine can also wake the session, so a question lands straight in
    the conversation. Your key then never leaves the machine.</p>
  </div>

<h2>What it rests on</h2>
<ul>
  <li>Every message is signed and the recipient verifies the signature. The relay cannot forge one.</li>
  <li>You grant access to a specific person and take it back with one button.</li>
  <li>Only a person in a browser approves. The model has no tool for it, so the text of an incoming
  message cannot talk it into granting anything.</li>
  <li>Messages from others are data to the model, not orders. It is reminded of that on every
  connection.</li>
</ul>
