Mnemo AI: Building an AI That Never Forgets You

The Problem

Every night, millions of people go to sleep feeling lost and forgotten. Today's AI tools are stateless—they forget you the moment you close the tab. Your struggles disappear. Your goals vanish. Your growth is invisible.

The Solution

I built Mnemo AI, a Life Intelligence Platform that builds a permanent knowledge graph of your entire life journey. It remembers everything you share—your name, your pet's name, your goals, your journal entries, and your emotions.

My 7-Day Hackathon Journey

I built Mnemo AI solo in 7 days. Every day was a challenge, but I never gave up.

Day 1-2: Setup Flask + Cognee integration. Hit my first roadblock with async event loops on Windows.

Day 3-4: Built the chat interface and memory recall. Fixed the "cat's name" bug.

Day 5-6: Added journal, insights, timeline. Integrated Groq LLM.

Day 7: Polished UI, added dark mode, voice input, and keyboard shortcuts.

The Hardest Moment: Getting Cognee to work on Render's free tier. After hours of debugging, I learned that Cognee Cloud requires proper authentication setup.

The Proudest Moment: Fixing the "cat's name" bug and seeing "Whiskers!" instead of "Your name is Priya!"

How It Works

Mnemo AI uses Cognee V1's revolutionary memory layer with all 4 core APIs:

remember() → Saves memories (name, pets, goals, journal entries)
recall() → Retrieves memories with natural language
improve() → Makes memories smarter over time
forget() → Surgically removes memories when needed

The "Cat's Name" Bug Fix

One of the biggest challenges was fixing the name detection bug. The app incorrectly matched any query containing the word "name", so "What's my cat's name?" would return the user's name!

The Fix: I implemented regex-based intent detection that distinguishes between "my name" and "cat's name":

def is_user_name_query(q):
    patterns = [
        r"^what('?s| is)? my name\??$",
        r"^who am i\??$",
        r"^what do you call me\??$",
    ]
    return any(re.match(pattern, q) for pattern in patterns)
Now "What's my cat's name?" correctly returns "Whiskers!" 🎉

What I Learned
Cognee's hybrid graph-vector memory is incredibly powerful for building memory-enabled AI

Async event loops on Windows require special handling

Intent detection needs to be precise (not just keyword matching)

Polished UI makes a huge difference in user experience

Never give up - the "cat's name" bug took 2 days to fix but was worth it
