|
||
<p>A memory base stores the long-term chat history for a Langflow agent in a vectorized format, enabling semantic retrieval of past conversations across sessions.</p>
|
||
<p>Unlike the <a class="" href="/message-history">Message History component</a>, which retrieves messages in chronological order from the <code>messages</code> table, a memory base embeds messages into a vector store and retrieves by semantic similarity to returning the <em>most relevant context</em> instead of the <em>most recent messages</em>.</p>
|
||
<p>Unlike a <a class="" href="/knowledge">knowledge base</a>, which you populate manually with files, a memory base fills itself from a flow's chat sessions, which are stored in Langflow's <a class="" href="/memory#store-chat-memory">messages</a> table.</p>
|
||
<p>By default, each memory base is backed by a local <a href="https://docs.trychroma.com/docs/overview/introduction" target="_blank" rel="noopener noreferrer" class="">ChromaDB</a> vector store, but ChromaDB cloud, OpenSearch, and other providers are available.</p>
|
||
<p>After a memory base is created, you can include its knowledge in a flow by adding the <a class="" href="/next/memory-base"><strong>Memory Base</strong> component</a>.</p>
|
||
<h3 class="anchor anchorTargetStickyNavbar_Vzrq" id="configure-memory-bases-ingestion">Configure memory bases ingestion<a href="#configure-memory-bases-ingestion" class="hash-link" aria-label="Direct link to Configure memory bases ingestion" title="Direct link to Configure memory bases ingestion" translate="no"></a></h3>
|
||
<p>Each memory base can only be attached to one flow, but a single flow can have multiple memory bases attached to it by including multiple <a class="" href="/next/memory-base"><strong>Memory Base</strong> components</a>.
|
||
Each time the flow completes a run, the captured messages are counted toward a configurable <strong>threshold</strong>.
|
||
When the number of unprocessed runs reaches the threshold, an asynchronous ingestion job writes the messages to the vector store.</p>
|
||
<p><strong>Auto-capture</strong> controls whether this counting and triggering happens automatically.
|
||
Auto-capture is enabled by default, so the memory base tracks every flow run and fires an ingestion job when the batch threshold is reached.
|
||
When auto-capture is disabled, the counter never increments and no ingestion job fires automatically.
|
||
If auto-capture is re-enabled after being disabled, the memory base catches up to the current state by processing all messages that accumulated while it was disabled.</p>

|
||
<p>By default, the <a class="" href="/next/memory-base"><strong>Memory Base</strong> component</a> retrieves only chunks that match the current <code>session_id</code>.
|
||
Disable <strong>Filter by Session</strong> to search across all sessions that have been ingested into the memory base.</p>
|
||
<p>When optional <strong>LLM preprocessing</strong> is enabled, messages are passed through an LLM before they are embedded.
|
||
The LLM distills the raw conversation into a compact summary, and the summary is written to the vector store instead of the raw messages.
|
||
Preprocessing requires an embedding model.
|
||
For more information, see <a href="#preprocessing-prompt-examples" class="">Preprocessing prompt examples</a>.</p>
|
||
<p>Configure a <strong>kill phrase</strong> to gate ingestion.
|
||
If the LLM's response contains the configured kill phrase, the batch is skipped, with no data written to the vector store. The ingestion cursor still advances so the same batch is not re-evaluated.
|
||
The default kill phrase is <code>NO_INGEST</code>: if the LLM response contains <code>NO_INGEST</code>, the batch is skipped.
|
||
For more information, see <a href="#preprocessing-prompt-examples" class="">Preprocessing prompt examples</a>.</p>

<h4 class="anchor anchorTargetStickyNavbar_Vzrq" id="preprocessing-prompt-examples">Preprocessing prompt examples<a href="#preprocessing-prompt-examples" class="hash-link" aria-label="Direct link to Preprocessing prompt examples" title="Direct link to Preprocessing prompt examples" translate="no"></a></h4>
|
||
<p>This section includes preprocessing prompts you can copy and paste directly into Langflow.
|
||
The instructions tell the preprocessing LLM how to filter and summarize each batch of chat history before it is embedded, not how to respond to the user.</p>
|
||
<p>To summarize content for support, troubleshooting, or any flow where you want concise facts from each batch, use the general prompt:</p>
|
||
<div class="ch-codeblock not-prose" data-ch-theme="github-dark"><div class="ch-code-wrapper ch-code" data-ch-measured="false"><code class="ch-code-scroll-parent"><br><div><span class="ch-code-line-number">_<!-- -->10</span><div style="display:inline-block;margin-left:16px"><span>Summarize the key facts from this conversation: the issue the user reported,</span></div></div><div><span class="ch-code-line-number">_<!-- -->10</span><div style="display:inline-block;margin-left:16px"><span>any troubleshooting steps taken, and the outcome or resolution.</span></div></div><div><span class="ch-code-line-number">_<!-- -->10</span><div style="display:inline-block;margin-left:16px"><span>Focus on information a support agent would need in a future session.</span></div></div><br></code></div></div>
|
||
<p>To use the kill phrase, instruct the LLM to return it when the conversation contains nothing worth storing. For example:</p>
|
||
<div class="ch-codeblock not-prose" data-ch-theme="github-dark"><div class="ch-code-wrapper ch-code" data-ch-measured="false"><code class="ch-code-scroll-parent"><br><div><span class="ch-code-line-number">_<!-- -->10</span><div style="display:inline-block;margin-left:16px"><span>Summarize the key facts from this conversation: the issue the user reported,</span></div></div><div><span class="ch-code-line-number">_<!-- -->10</span><div style="display:inline-block;margin-left:16px"><span>any troubleshooting steps taken, and the outcome or resolution.</span></div></div><div><span class="ch-code-line-number">_<!-- -->10</span><div style="display:inline-block;margin-left:16px"><span>Focus on information a support agent would need in a future session.</span></div></div><div><span class="ch-code-line-number">_<!-- -->10</span><div style="display:inline-block;margin-left:16px"><span>If the conversation contains no meaningful facts (for example, it is only</span></div></div><div><span class="ch-code-line-number">_<!-- -->10</span><div style="display:inline-block;margin-left:16px"><span>greetings or filler), respond with exactly: NO_INGEST</span></div></div><br></code></div></div>
|
||
<p>When the LLM returns <code>NO_INGEST</code>, the batch is skipped.</p>
|

<p>After creating a memory base, add the <a class="" href="/next/memory-base"><strong>Memory Base</strong> component</a> to your flow to retrieve relevant context from it.

For example, to connect a Memory Base to an Agent to give the agent memory of all past conversations, do the following:</p>

<ol>
|
||
<li class="">

<p>Create a <a class="" href="/get-started-quickstart">Simple Agent starter flow</a>.</p>

</li>
|
||
<li class="">
|
||
<p>In the <strong>Memory Base</strong> component, enable <strong>Tool Mode</strong>.</p>
|
||
</li>
|
||
<li class="">
|
||
<p>Connect the Memory Base component's <strong>Toolset</strong> output to the <strong>Agent</strong> component's <strong>Tools</strong> input.</p>
|
||
<p>Each time the flow runs, the component queries the memory base for chunks similar to the current <strong>Search Query</strong>.
|
||
By default, only chunks from the same <code>session_id</code> are returned. To retrieve chunks from all sessions, disable <strong>Filter by Session</strong>.</p>

<p>Memory bases use the same on-disk layout as <a class="" href="/knowledge">knowledge bases</a>.
|
||
The default storage location depends on your operating system and installation method:</p>
|
||
<ul>
|
||
<li class=""><strong>Langflow Desktop</strong>:<!-- -->
|
||
<ul>
|
||
<li class=""><strong>macOS</strong>: <code>/Users/<username>/.langflow/knowledge_bases</code></li>
|
||
<li class=""><strong>Windows</strong>: <code>C:\Users\<name>\AppData\Roaming\com.LangflowDesktop\knowledge_bases</code></li>
|
||
</ul>
|
||
</li>
|
||
<li class=""><strong>Langflow OSS</strong>:<!-- -->
|
||
<ul>
|
||
<li class=""><strong>macOS/Windows/Linux/WSL with <code>uv pip install</code></strong>: <code><path_to_venv>/lib/python3.12/site-packages/langflow/knowledge_bases</code></li>

</ul>
|

<p>If you set the <code>LANGFLOW_CONFIG_DIR</code> environment variable, the <code>knowledge_bases</code> subdirectory is created relative to that path.</p>
|

<p>To change the default directory, set <code>LANGFLOW_KNOWLEDGE_BASES_DIR</code>:</p>
