+## Memory in Flows
+
+Every Flow automatically has access to CrewAI's unified [Memory](/concepts/memory) system. You can store, recall, and extract memories directly inside any flow method using three built-in convenience methods.
+
+### Built-in Methods
+
+| Method | Description |
+| :--- | :--- |
+| `self.remember(content, **kwargs)` | Store content in memory. Accepts optional `scope`, `categories`, `metadata`, `importance`. |
+| `self.recall(query, **kwargs)` | Retrieve relevant memories. Accepts optional `scope`, `categories`, `limit`, `depth`. |
+| `self.extract_memories(content)` | Break raw text into discrete, self-contained memory statements. |
+
+A default `Memory()` instance is created automatically when the Flow initializes. You can also pass a custom one:
+
+```python
+from crewai.flow.flow import Flow
+from crewai import Memory
+
+custom_memory = Memory(
+    recency_weight=0.5,
+    recency_half_life_days=7,
+    embedder={"provider": "ollama", "config": {"model_name": "mxbai-embed-large"}},
+)
+
+flow = MyFlow(memory=custom_memory)
+```
+
+### Example: Research and Analyze Flow
+
+```python
+from crewai.flow.flow import Flow, listen, start
+
+
+class ResearchAnalysisFlow(Flow):
+    @start()
+    def gather_data(self):
+        # Simulate research findings
+        findings = (
+            "PostgreSQL handles 10k concurrent connections with connection pooling. "
+            "MySQL caps at around 5k. MongoDB scales horizontally but adds complexity."
+        )
+
+        # Extract atomic facts and remember each one
+        memories = self.extract_memories(findings)
+        for mem in memories:
+            self.remember(mem, scope="/research/databases")
+
+        return findings
+
+    @listen(gather_data)
+    def analyze(self, raw_findings):
+        # Recall relevant past research (from this run or previous runs)
+        past = self.recall("database performance and scaling", limit=10, depth="shallow")
+
+        context_lines = [f"- {m.record.content}" for m in past]
+        context = "\n".join(context_lines) if context_lines else "No prior context."
+
+        return {
+            "new_findings": raw_findings,
+            "prior_context": context,
+            "total_memories": len(past),
+        }
+
+
+flow = ResearchAnalysisFlow()
+result = flow.kickoff()
+print(result)
+```
+
+Because memory persists across runs (backed by LanceDB on disk), the `analyze` step will recall findings from previous executions too -- enabling flows that learn and accumulate knowledge over time.
+
+See the [Memory documentation](/concepts/memory) for details on scopes, slices, composite scoring, embedder configuration, and more.

-        \ Objects**\\n\\n**Explanation:**  \\nAt its core, addition is all about combining\
-        \ two or more groups of things to find out how many there are in total. We\
-        \ can think of addition as a way to bring friends together! Imagine if you\
-        \ have some apples and your friend brings some more apples; together, you\
-        \ want to find out how many apples there are altogether. This is the foundation\
-        \ of addition, and it can be made fun and engaging for a 6-year-old.\\n\\\
-        n**Angle:**  \\nTo make this relatable and enjoyable, we can use everyday\
-        \ objects that kids love, such as toys, fruits, or even drawings. We can create\
-        \ little stories or scenarios that involve addition, turning it into a game\
-        \ where they get to count and add things together. By using real items, children\
-        \ can see and feel what addition means, making it easier to grasp the concept.\\\
-        n\\n**Examples:**  \\n1. **Using Fruits:**  \\n   Let's say you have 3 oranges.\
-        \ You can say, \\\"I have 3 oranges.\\\" Then, if your friend brings you 2\
-        \ more oranges, you can introduce the addition by saying, \\\"Now, how many\
-        \ do we have all together?\\\"  \\n   - So you would show it as: 3 (oranges\
-        \ you have) + 2 (oranges your friend brought) = ?  \\n   To find the answer,\
-        \ you can count all the oranges together: 1, 2, 3 (your oranges) and 4, 5\
-        \ (your friend's oranges).  \\n   - The answer is 5 oranges in total!\\n\\\
-        n2. **Using Toys:**  \\n   If a child has 4 toy cars and finds 3 more under\
-        \ the couch, we can ask, \\\"How many cars do you have now?\\\"  \\n   - Write\
-        \ it down: 4 (toy cars) + 3 (found cars) = ?  \\n   Then, count the toy cars\
-        \ together: 1, 2, 3, 4 (original cars), 5, 6, 7.  \\n   - The answer is 7\
-        \ toy cars!\\n\\n3. **Story Scenario:**  \\n   Create an engaging story: \\\
-        \"Once upon a time, there were 2 friendly puppies. One day, 3 more puppies\
-        \ came to play. How many puppies are playing now?\\\"  \\n   - Present it\
-        \ as: 2 (original puppies) + 3 (new puppies) = ?  \\n   Count the puppies:\
-        \ 1, 2 (the first two) and then 3, 4, 5 (the new ones).  \\n   - The answer\
-        \ is 5 puppies playing!\\n\\nBy presenting addition through fun scenarios\
-        \ and interactive counting, a 6-year-old can learn and understand addition\
-        \ while enjoying the process. They can even use crayons to draw the items\
-        \ or fruit to count in a playful, hands-on approach. This makes math not just\
-        \ a subject, but also a delightful adventure!\",\n        \"refusal\": null,\n\

-        \ answer  \\nFinal Answer: \\n\\n**Topic:** Introduction to Addition\\n\\\
-        n**Explanation:**  \\nAddition is a fundamental concept in math that means\
-        \ putting together two or more numbers to find out how many there are in total.\
-        \ When we add, we combine quantities to see the total amount we have. The\
-        \ symbol for addition is \\\"+\\\". \\n\\nLet's break it down so it's easy\
-        \ to understand. If you have a small group of apples and then you get more\
-        \ apples, to find out how many apples you have altogether, you add them up!\
-        \ \\n\\n**Angle:**  \\nTo teach this concept to a 6-year-old, we can use tangible\
-        \ objects they can relate to, such as fruits, toys, or stickers. Kids learn\
-        \ best through play and visual representation, so using real-life examples\
-        \ will make the concept of addition exciting and engaging!\\n\\n**Examples:**\
-        \  \\n1. **Using Fruits:** \\n   - Start with 2 apples. \\n\\n     \U0001F34F\
-        \U0001F34F (2 apples)\\n\\n   - Then, you receive 3 more apples. \\n\\n  \
-        \   \U0001F34F\U0001F34F\U0001F34F (3 apples)\\n\\n   - To find out how many\
-        \ apples you have now, we add them together: \\n\\n     2 + 3 = 5 \\n\\n \
-        \  - Show them the total by counting all the apples together: \\n\\n     \U0001F34F\
-        \U0001F34F\U0001F34F\U0001F34F\U0001F34F (5 apples)\\n\\n2. **Using Toys:**\
-        \ \\n   - Let’s say there are 4 toy cars. \\n\\n     \U0001F697\U0001F697\U0001F697\
-        \U0001F697 (4 toy cars)\\n\\n   - If you get 2 more toy cars. \\n\\n     \U0001F697\
-        \U0001F697 (2 toy cars)\\n\\n   - How many do we have in total? \\n\\n   \
-        \  4 + 2 = 6 \\n\\n   - Count them all together: \\n\\n     \U0001F697\U0001F697\
-        \U0001F697\U0001F697\U0001F697\U0001F697 (6 toy cars)\\n\\n3. **Using Stickers:**\
-        \  \\n   - You have 5 stickers. \\n\\n     \U0001F31F\U0001F31F\U0001F31F\U0001F31F\
-        \U0001F31F (5 stickers)\\n\\n   - Your friend gives you 4 more stickers. \\\
-        n\\n     \U0001F31F\U0001F31F\U0001F31F\U0001F31F (4 stickers)\\n\\n   - Now,\
-        \ let’s see how many stickers you have in total: \\n\\n     5 + 4 = 9 \\n\\\
-        n   - Count them together: \\n\\n     \U0001F31F\U0001F31F\U0001F31F\U0001F31F\
-        \U0001F31F\U0001F31F\U0001F31F\U0001F31F\U0001F31F (9 stickers)\\n\\n**Conclusion:**\
-        \  \\nTry to make addition fun! Use snacks or play time to practice addition.\
-        \ Ask questions during snack time, such as “If you eat one of your 5 cookies,\
-        \ how many will you have left?” This approach makes learning relatable and\
-        \ enjoyable, enhancing their understanding of math in everyday situations.\
