Does CrewAI Remember Between Runs? What memory=True Actually Persists

You set up a CrewAI crew that runs every morning at 7. It digs through industry news, writes you a brief, and drops it in Slack. The first week feels like magic. By week three something is off: it re-researches the same topics, forgets the competitor you ruled out last month, and asks which "Acme" you meant even though you told it twice. But you set memory=True. So what is that flag actually doing?

What memory=True enables

CrewAI ships four memory types that work together when you pass memory=True to the Crew:

• Short-term memory (ChromaDB + RAG): recent interactions during the current execution. It keeps the crew coherent within one kickoff.
• Long-term memory (SQLite): persists insights across sessions. After a run, useful learnings are stored and can be retrieved next time.
• Entity memory (RAG): tracks people, places, and concepts the crew encounters.
• Contextual memory: combines the other three so each agent step gets the right context.

So strictly speaking, yes, CrewAI remembers things between runs, at least through the long-term and entity layers. That is the honest answer. Now here is the part that matters if you run crews on a schedule.

What actually survives a kickoff

Long-term memory stores extracted insights, not the conversation. CrewAI distills "useful learnings" from a run into short notes. It does not keep the full transcript of what the agents said and did. Next Monday's run gets a distilled summary of last Monday's run, filtered through whatever the distillation step considered worth keeping. If the detail you need never made it into an insight, it is gone.

The memory also lives in a local SQLite file on the machine that ran the crew. That is the bigger issue. If your crew runs on your laptop, the file is there next time and long-term memory works roughly as advertised. If your crew runs on a schedule somewhere else, a cron job on a container, a GitHub Actions runner, a serverless function, the SQLite file starts empty every single run. Your "long-term" memory has the lifetime of one execution, because the storage itself was ephemeral.

And the memory belongs to that one crew. Your other tools cannot read it. The assistant in Cursor, the support bot, the agent triaging your inbox: none of them see what the crew learned. Each CrewAI crew is a memory island.

Three limits that hit scheduled operators hardest

1. Ephemeral runners wipe local state. Most scheduled crews do not run on a laptop. They run in Docker containers that get rebuilt, cloud functions that spin down, CI runners that vanish. Anything stored in a local SQLite file dies with the container. Your schedule says "daily crew"; your infrastructure says "amnesiac every day."

2. Insights are not history. "We decided to stop tracking competitor X" is an insight that might get stored. The three paragraphs explaining why, the failed approach, the dead-end source: those are the parts you actually need when the crew argues with itself next month. Distilled summaries age badly. Full history lets you revisit the real conversation.

3. No cross-tool continuity. You do not have one agent; you have a stack. The crew researches, a different tool writes, another tool posts. If each keeps its own local notes, you are re-briefing every tool forever. The context tax never goes down.

Your options, honestly

Option one: keep CrewAI's memory and make the storage durable. Mount a persistent volume, run the crew on a stable machine, back up the SQLite file. This fixes the ephemeral-runner problem and nothing else. The memory still stores insights rather than history, and it still belongs to one crew.

Option two: give the agents explicit memory tools backed by a real backend. CrewAI supports pluggable external memory. Agents call a store tool and a search tool, and you control exactly what gets remembered, namespaced by project or customer. This works, but now you are building and operating a memory service: schema, retrieval, deletion, exports, uptime. That is a second product wearing your automation's clothes.

Option three: use a shared memory layer that lives outside every tool. This is the one worth understanding, because it fixes all three limits at once.

One memory for every agent, not one per crew

Vilix AI is a cloud-hosted memory layer, so you manage zero infrastructure. It is hosted in the cloud and you manage nothing. Connect each AI client to the same Vilix AI account and the same memory follows everywhere over MCP: your scheduled CrewAI crew, Cursor, Claude, OpenClaw, Codex, any MCP-compatible tool. Headless agents connect with an API key as a Bearer header to the MCP endpoint, which is exactly how a scheduled crew authenticates.

The model is simple: save_turn stores the exchange, get_context loads relevant context back in. Retrieval is semantic, with keyword matching alongside it, so exact strings like order IDs and names are matched literally while concepts are matched by meaning. The crew pulls what it meant to find, not just what it typed.

And unlike insight distillation, Vilix AI keeps the full conversation history, not just facts. You can revisit what the crew actually said and did, not a summary of it. For a scheduled operator, the practical differences:

• The memory is cloud-hosted, so ephemeral runners do not matter. The container dies; the memory lives on.
• One memory serves the whole stack. The crew's research is visible to the agent that writes the brief, and vice versa.
• Your data stays yours: export everything in a portable format anytime, or delete individual memories or wipe the account instantly.
• Free plan forever, and a 7-day Pro trial with no credit card, so you can wire the crew up and see whether shared memory changes the Monday-morning brief before paying anything.

There is also a free discipline fix worth adding no matter which option you pick: tell the crew to read memory before it acts. Put it in the task description: "First, search memory for prior research on this topic. Then do the work. Then store the key findings." Agents follow the task. Most crews never get that instruction, so they have memory available and never touch it.

The verdict

Does CrewAI remember between runs? The technically true answer: with memory=True, its long-term and entity memory persist extracted insights across sessions on the machine where the crew runs. The practically true answer for a scheduled operator: treat that as within-machine, insight-level memory. If your runs are scheduled, ephemeral, or spread across tools, give the crew a shared memory layer it can reach from anywhere. Your crew should wake up already knowing last week, not relearning it.
