<h1 id="bear-integration-for-long-term-memory">Bear Integration for Long-Term Memory<a class="headerlink" href="#bear-integration-for-long-term-memory" title="Permanent link">¶</a></h1>
<p>CortexGraph can use the <a href="https://bear.app/">Bear note-taking app</a> as a long-term memory (LTM) store, providing a powerful alternative to the default Obsidian integration. This guide explains how to set it up and use it.</p>
<h2 id="overview">Overview<a class="headerlink" href="#overview" title="Permanent link">¶</a></h2>
<p>The Bear integration uses a hybrid architecture for optimal performance and safety:
- <strong>Fast Reads</strong>: It reads directly from Bear's local SQLite database for high-speed searching and indexing.
- <strong>Safe Writes</strong>: It uses Bear's official <code>x-callback-url</code> API for creating and modifying notes, ensuring full compatibility with iCloud sync.</p>
<p><strong>Platform Limitation:</strong> Please note that Bear is only available on macOS and iOS. This integration will only work on <strong>macOS</strong>.</p>
<h2 id="configuration">Configuration<a class="headerlink" href="#configuration" title="Permanent link">¶</a></h2>
<p>To enable the Bear integration, you need to configure a few settings in your <code>.env</code> file.</p>
<p>First, copy the example environment file if you haven't already:
<div class="highlight"><pre><span></span><code><a id="__codelineno-0-1" name="__codelineno-0-1" href="#__codelineno-0-1"></a>cp<span class="w"> </span>.env.example<span class="w"> </span>.env
</code></pre></div></p>
<p>Next, add the following variables to your <code>.env</code> file:</p>
<div class="highlight"><pre><span></span><code><a id="__codelineno-1-1" name="__codelineno-1-1" href="#__codelineno-1-1"></a><span class="c1"># --- Bear LTM Integration ---</span>

<p>Once configured, you can promote memories to Bear using the <code>promote_memory</code> tool.</p>
<h3 id="promoting-a-memory-to-bear">Promoting a Memory to Bear<a class="headerlink" href="#promoting-a-memory-to-bear" title="Permanent link">¶</a></h3>

<p>This will create a new note in Bear with the memory's content and associated metadata.</p>
<h3 id="unified-search">Unified Search<a class="headerlink" href="#unified-search" title="Permanent link">¶</a></h3>
<p>When <code>CORTEXGRAPH_BEAR_ENABLED</code> is set to <code>true</code>, the <code>search_unified</code> tool will automatically include Bear notes in its search results, alongside short-term memories and Obsidian notes.</p>
