Hey, it’s Tom. Over the years I’ve built and interacted with more chatbots than I can count. One of my early efforts, however, I will never forget. It was a simple customer service bot. One user spent 10 minutes explaining their complex problem before being disconnected. When they returned, the bot said “Hello! How can I help you today?” with the same voice as though they had never met. The user’s frustration was almost palpable.
This moment crystallized an essential truth for me: Without memory, an AI is simply a tool. With memory, it may become a real companion. The magic of it is not to reply to queries, but to remember. It is all the difference in the world between a speed bump experience and a long-term real experience. Platforms like Nomi.ai and candy.ai are exploring how memory can deepen these connections.
Today, I would like to share with you how we can give our bots the extraordinary gift of memory. We will explore the underlying principles and then move on to three practical applications of mine as memory slots, journals, and recap prompts that I have used for making bots not simply respond, but remember so as to create a genuine continuity and friendship.
The Crux of it All: What is Bot Memory?
AI memory is therefore the capacity to store and retrieve information from earlier interactions. It is the difference between being a lovable memory for partner and being an unlovable non-mumblist. In our human relationships, witnesses agree we have a shared history with the other and the understanding of the other that it implies, we remember birthdays, the conversation we had before and the other one’s quirks, persona and likes. This is the goal for conversational AI and achieving it allows users to feel seen, heard, and valued. You can see this in action on platforms like SecretDesires and Sweetdream.ai.
In AI, memory is typically discussed in two forms, much like our own:
- Short Term Memory: This is the “working memory” of the AI, holding the context of the current conversation. Most modern bots will use some sort of a
context windowto remember the last few messages to help the conversation flow logically together in one sitting. - Long Term Memory: This is the Holy Grail. It is the long-term storage of critical information across days, weeks, even months. This is where user preferences and critical life details and past project goals are stored, ultimately creating the basis for a long-term relationship. This is often powered by technologies like vector databases and a technology called Retrieval-Augmented Generation (RAG).
While short-term memory helps relieve immediate frustration, it is long-term memory that provides the overall transformation of the user experience. For a deeper dive into how different platforms compare, check out my Ourdream.ai vs Herahaven comparison.
3 Core Techniques for a Bot with Memory
So how do we go from theory to practice? Creating a bot with effective long-term memory requires careful architecture. Here are 3 of my favorite techniques for creating and keeping conversational continuity.
1. Memory Slots: The Digital Post-it Notes
I like to think of memory slots like folders with labels in the AI’s brain. Rather than saving a huge garbage transcript of every conversation being stored, we set aside specific, designated “slots” for key pieces of information.
How it works: You define slots for key user properties such as user_name, user_location or user_goal. Whenever a user notes a key fact, the AI’s Natural Language Understanding (NLU) system plugs the fact into the right slot.
This systematic approach is terrific for personalization. A bot that remembers a user is trying to learn to play the guitar could ask unnecessarily, “Have you had a chance to practice that G chord that we talked about last week?” This slight bit of recollection shows sincere attentiveness and elevates the interaction as a whole. Here is a simple example of how this works in reality:
| Memory Slot | User Input | Bot Action |
|---|---|---|
user_favorite_music | “I have been listening to a lot of classical music lately.” | Updates the user_favorite_music slot with “classical.” |
user_goal | “I am trying to learn to cook.” | Builds a new memory slot user_goal and puts “learning to cook” in it. |
2. Journals: Co-creating a Shared History
While slots are ideal for discrete facts, journals are for building a story. This technique consists of creating a continuous (and chronological) record of significant interactions–making the conversations a shared story.
How it works: At the end of a meaningful session, the AI can be asked for a summary of important things that occurred. For example, “Today we brainstormed ideas with respect to your novel, and we did an outline for the first three chapters. The main character, a detective named Alex, just made an important discovery of a mysterious clue." This summary is then filed away as an entry in a "journal." I've seen this work wonders in coaching or companion type bots like those from ourdream.ai or herahaven.com. The journal becomes a common history the AI can recall to track progress, remember meaningful milestones, and help a user reflect on his journey. It makes the AI into a partner instead of just an assistant.
3. Recap Prompts: The “Just to Confirm…” Superpower
This is one of the simplest ideas, and most powerful, for ensuring a seamless flow in a conversation especially if the user comes back after a break. A recap prompt is an adjustable reminder of where a user left off.
How it works: At the start of the new conversation, the AI gives a brief summary of the last one. "Welcome back Tom! Last time we were discussing your marketing plan for the new product release. Shall we pick things up from there?" This simple gesture does two important things. It saves the user the trouble of having to re-explain himself, and it shows the bot was "listening." It instantly re-establishes context and makes the conversation feel more efficient and natural.
How to Create a Bot with a Memory: A 5-Point Guide
Ready to put these concepts into practice? It might seem complicated, but it boils down to a few key steps. Here’s a simple guide to getting started.
- Step 1: Decide what to remember. Identify key facts about users that will make the bot more helpful, such as names, locations, preferences, or long-term goals.
- Step 2: Create memory slots. Define specific "slots" in your bot's architecture to store each piece of information (e.g., a
user_nameslot). - Step 3: Train your NLU to extract. Teach your bot’s Natural Language Understanding (NLU) model to recognize these key facts (entities) in user input.
- Step 4: Link entities to slots. Build logic that automatically places an extracted entity into its designated memory slot for future use.
- Step 5: Personalize the conversation. Program the bot to use the information in its memory slots to provide relevant and personalized responses. Services like SecretDesires and Sweetdream.ai excel at this.
- Give Users Control and Visibility: Help build trust in your bot by including simple commands such as "What do you remember about me?" and "Forget my name." Providing transparency into what the bot knows and giving the user control over this is important to avoid the "creepy" factor. I discuss the importance of this in my article on the AI girlfriend landscape.
The Future is Memorable
We’re at an exciting inflection point. The leap from stateless bots to companions with permanent or long term memory is revolutionizing the human-AI relationship. By using techniques like memory slots, journaling and recapping with foresight we are able to build AI that does not merely process our words, but remembers our stories. This will allow us to create digital partners who help us achieve our goal, celebrate various milestones and share in our growth, a trend we see with services like golove.ai.
The goal isn’t simply to create a bot which remembers a name, but a bot which assists us in creating a better version of ourselves. And that’s a future that I’m extremely excited to be involved with.
