Nova Mind and its Persistent Memory

Well, everyone who’s worked seriously with AI knows it: it’s annoying. Yes, it’s annoying! Annoying to have to type, to repeat everything, 5 times, 10 times, annoying to rehash, to have to re-explain who you are, what you work on, etc.

Result? 95% of AI projects fail because there’s too much friction between the chair and the keyboard.

We experienced it ourselves at Digital Cookie, and we did everything to solve it: and that’s how Nova was born…

The solution: being lazy.

Under this intentionally shocking title, a simple truth: working while spinning your wheels is a no. You have to constantly optimize your workflow, and to be productive with a tool you spend all day on, you shouldn’t “type” on your keyboard. You should talk.

Today, voice recognition has become remarkably effective. OpenAI’s Whisper understands almost everything, even your hesitations and “ums”. Result? You can dictate your thoughts at the speed of your brain, not your fingers.

Even native Microsoft solutions do the job: the hardest part is changing your habits…

The time gain is huge: 150 words per minute by voice versus 40 on keyboard. That’s almost 4 times faster! No more cramps, no more typos, no more “I lost my train of thought while typing”.

You speak, your AI agent understands, and it acts. Period.

But even when speaking, the problem remains: AI forgets everything. Each new conversation means starting from scratch. Explaining your context, your projects, your constraints… Once, ten times, a hundred times. Horror.

And that’s exactly what we solved with Nova-Mind.

The context problem

I still see LinkedIn users promoting the virtues of their “magic prompt”. A prompt for this, a prompt for that, the “secret prompt” that will allow you to dominate the world without moving from your chair, that will allow you to blow everything up and scale blahblahblah…

Let’s just say if you’re still there, you’re REALLY behind.

Today, it’s not the prompt that counts: it’s context generation. And if we want to go even further: DYNAMIC context generation!

We can use a “memory-bank” initially (a file system), but the maintenance problem arises. It’s long. It’s annoying. And not dynamic at all.

So we need to automate the process. That’s what will create this feeling of “familiarity” between the user and their AI Agent.

The real challenge: How to make Nova know you as well as a colleague who’s been working with you for months? How to give it a memory that grows and enriches naturally?

That’s where we innovated: by creating a tool that will “generate context” dynamically, an evolving context that changes… with you!

The memory problem… But what memory?

Who are you? What do you do (generally)? What are you working on? With what tools? What are your concerns?

You need to know all that to get a custom AI agent. That helps. Really.

But we also need to go further: How do you evolve? What are your recurring patterns? Your motivation cycles? Your procrastination habits?

That’s a real relational memory, and it will translate through two dimensions… Or rather two temporalities

Temporality 1: short-term memory

What were you working on yesterday? And 10 minutes ago? Without absolute continuity, we’re back to square one: we repeat.

Yes, unfortunately, when you start a new conversation, something terrible happens: your AI forgets everything.

But not Nova!

Our innovation: A real-time memory system that records every significant interaction immediately. No need to wait, no more “updates” - Nova instantly knows what happened during your last conversation. How? Thanks to dual data recording:

• First time in a classic DB
• Second time in a vector DB

To this, we couple maintenance logic that will recompile and consolidate this memory on a daily/weekly/monthly basis.

While you go about your business, ChatGPT discreetly analyzes your interactions and creates intelligent summaries of your conversations, to guarantee the “freshness” of your “user context”.

In addition to this intelligent consolidation, Nova automatically updates your main context elements every day: your current goals, ongoing projects, behavioral preferences. Everything evolves with you, without you lifting a finger.

Result? You connect in the morning, and Nova remembers your important conversations from the day before, but also from the past week or month…

Your more “generic” data is stored differently and updated in real-time based on your interactions with Nova: the lady knows you and auto-maintains your context if something important changes.

Long-term memory

For the long term, we thought big: a vector DB with pgvector integrated directly into our infrastructure.

A vector DB, to put it simply, is a database where “Frog” can be found by searching for “amphibian” or “toad”, or even “green thing that jumps”.

So if you ask Nova “give me back the Leonardo MCP doc we saved on Notion”, Nova will know where to find it… Because she memorized it.

The revolutionary architecture:

┌─ SEMANTIC SEARCH ────────────────────────┐
│ • 100,000+ accessible memories          │  🔍 pgvector
│ • Finds any information                 │  ⚡ Instant results
│ • Intelligent connections               │  🧠 Hidden patterns
└──────────────────────────────────────────┘

Concretely: Nova can find a conversation from 6 months ago about a specific project, analyze your evolution patterns over a year, or identify that “you’re always stressed on Monday mornings for the past 3 months”.

It’s a relational memory, not just informational.

Smoothing and optimizing UX

And then after all that, there’s UX smoothing.

The technical challenge: How to do all this WITHOUT it being slow? How to avoid “Nova thinking for 30 seconds”?

Time management

We did everything we could to make the tool as fast as possible, non-intrusive, and to insert execution times during time when you’re acting (in the background). You thus have the least interruption in your workflow.

Honestly, nothing very complicated, we just had to be smart, by exploiting the natural dead times of human-machine interaction and setting up CRON tasks. Most maintenance phases are asynchronous and managed at night, at times when we hope you’re sleeping peacefully.

The revolutionary impact

This persistent memory architecture changes everything:

• ✅ Zero friction: Never again “repetitions”
• ✅ Authentic relationship: Nova truly knows you
• ✅ Long-term insights: Patterns and progressions revealed

If you use a speech-to-text tool, here’s what will happen: you’ll literally feel like Tony Stark talking to Jarvis. There.

You can even work while cooking, telling Nova what to do (would you believe me if I told you I’m writing this article while making crepes? Because that’s the case, you know)…

Conclusion: The era of AI that remembers

We just solved modern AI’s biggest problem: permanent amnesia that kills productivity.

For the first time, an AI architecture can:

• Instantly memorize every significant interaction
• Intelligently consolidate your data over months and years
• Semantically retrieve any past information
• Automatically maintain your user context

This is no longer disposable conversational AI, it’s persistent AI.

No more repeating 50 times who you are, what you work on, what your tools are. No more magic prompts to copy-paste. No more feeling like talking to a wall that forgets everything.

Nova-Mind inaugurates a new era: that of memorial AI agents, which accumulate knowledge, learn from your patterns, and become exponentially more useful over time.

The future of work will be augmented. Human + persistent AI, in continuous synergy.

We just built the foundations of this future.
