## Projects

### 1. Multi-Agent Planner: Intelligent Agent Selection with Vector Memory

Solves the fundamental problem: "What's the right set of agents for each task?" The system automatically determines optimal agent composition (research, coding, review, etc.) for each unique task, then uses MongoDB's vector search to learn from similar past tasks and optimize costs. Every prompt served extends the stored memory, making the system more efficient over time.

### 2. Hypernym

A chat-first “vibe” recommender for movies that uses two agents to converge on intent: BEST (Llama) argues for the most on-vibe pick; WORST (Claude) argues for the intentionally off-vibe counterexample. Users can fork either agent into threads—BEST accumulates include-tags, WORST accumulates exclude-tags—so intent sharpens fast.
Under the hood, we assemble a candidate set from MongoDB (sample_mflix), pass the same candidates to both models via ch.at (OpenAI-compatible), and return strict-JSON “receipts” (strong/weak details + tags_hit/tags_miss). It’s a general pattern for ambiguous preference search and showcases how evidence selection differs across models on the same corpus.

### 3. Context Relay

Context Relay System is a FastAPI-based middleware that enables seamless coordination among multiple AI agents. It manages, merges, and transfers conversational context across agents while using semantic embeddings to detect conflicts, filter noise, and preserve shared understanding over time. By maintaining a continuous and versioned flow of context, it turns fragmented agent interactions into cohesive collaboration.

In contrast to traditional message passing or naive context sharing, Context Relay builds a shared semantic memory layer that allows agents to operate with awareness of each other’s reasoning and history. This system addresses one of the hardest challenges in multi-agent architectures: keeping distributed intelligence aligned, synchronized, and grounded in a consistent world model.

### 20. KartGPT

Our project is a compound AI model for playing the online video game slowroads.io. We experimented with various data representations for the game state and found that using the road’s left and right coordinates along with the car’s position and velocity gave the best results. A simple CNN with edge-detection kernels extracts the road boundaries, while another model detects the car’s velocity from the game’s display. This data is then fed into an LLM to decide actions like moving forward or turning. Beyond performance, we compared multiple data formats to identify the most effective structure for agentic reasoning and introduced agent-to-agent context sharing, allowing models trained on separate sessions to exchange learned patterns—leading to more cohesive, adaptive, and human-like driving behavior.

### 24. llama-wolf

We build a social-deduction game arena (Werewolf) to test a practical memory architecture for language-model agents. Instead of retrieving long chat logs, our agent learns strategy memory: compact, reusable snippets that map situation → tactic → why. After each game, we distill tactics from logs (positive and negative), keyed by role (Villager/Seer/Werewolf), phase (accuse/defend/vote/night), and a small set of cue features (e.g., day bucket, counterclaim status, pressure, claims). At decision time, the agent filters by role/phase, recalls top-k tactics via a vector search over a canonicalized “situation string,” 

We run a teacher→student setup: GPT-5 and Llama-Maverick generate diverse training games; we extract and score tactics (win rate, vote-shift, acceptance/backfire, recency). At runtime, only Llama plays, with and without memory, against GPT-5 and Llama opponents under identical prompts and sampling to isolate memory effects.

### 40. Ayman

AURA (Argument Unit Relational Analyzer)
A multi-agent legal intelligence system that solves context loss in legal workflows. Three specialized agents collaborate through shared MongoDB memory: ResearchAgent identifies relevant case precedents, AnalysisAgent evaluates argument strength using those precedents, and DraftingAgent synthesizes everything into legal briefs.
The key innovation is agent-to-agent context handoff. Each agent reads what the previous one wrote, adds its layer of analysis, and passes enriched context forward. No duplication, no re-research. The system structures legal knowledge as interconnected layers - foundation (precedents), strategic (analysis), and synthesis (draft) - all traceable through a visual Evidence Chain.

### 41. FraudChain

AI-powered fraud detection agent that analyzes transaction narratives, retrieves similar historical cases via Voyage AI embeddings, and generates draft risk summaries using FastAPI and MongoDB Atlas. 
Financial crime investigators and compliance analysts are overwhelmed by thousands of daily transaction alerts. Each alert requires reading long, unstructured narratives and manually comparing them to prior suspicious activity which is a slow, repetitive, and error-prone process.
This agent solves that problem by instantly analyzing previous cases and showing similarities to make catching fraud easier and faster.

### 43. contextScope

- ContextScope Eval is an open-source evaluation and observability framework for agent-to-agent context sharing. It measures how effectively autonomous agents pass and use information, tracking context fidelity, relevance drift, temporal coherence, and utility across multi-agent pipelines. Unlike traditional LLM benchmarks or AI Eval tool (which focus on accuracy or helpfulness), ContextScope measures information flow quality with high resolution visualization that provides actionable insights such like how context survives, transforms, and degrades as it moves through agents.

- The problem it solves: As multi-agent systems grow more complex, evaluating how well agents communicate and share memory becomes essential. Looking at the single points of evaluation metrics is no longer effective, current evaluation tools (eg. LangSmith, Braintrust, Traceloop) focus on reasoning steps or final outputs but not on context transmission itself. ContextScope Eval fills this gap.

### 46. Hypernym

MemoryAgent aligns user intent with persistent AI memory using Hypernym compression to create relevance-sorted slices ordered by LLM-perceived importance. Combined with Voyage’s domain embeddings, it reaches 81% fact-preservation correlation versus 78% for general models, enhancing both MongoDB and Voyage AI. Its 3-layer architecture (episodic, semantic, compressed) enables real-time learning with 75–80% similarity scores. MongoDB now captures critical info regardless of document size, rendering context windows irrelevant through intelligent slicing. Unlike static RAG systems, MemoryAgent learns and adapts. The demo shows 23 persistent memories, semantic clustering, and fact-preserving compression. Built with MongoDB Atlas Vector Search, Voyage AI embeddings, and Hypernym API, it scales to millions of users with adaptive compression efficiency.

### 57. Court Run

Traditional AI chatbots fail in legal proceedings as they lack memory and can't manage multi-party context. Court Run solves this with three specialized AI agents acting as Plaintiff, Defendant, and Judge in a simulated trial. Its core innovation is an intelligent context strategy where agents receive tailored information based on the trial phase. Early stages get summaries for focus, cross-examinations get raw messages to detect contradictions, and the verdict phase receives the full transcript. This ensures agents have the precise information needed without overload.

The technology's applications extend beyond courtrooms to M&A due diligence, compliance audits, and AI-driven legal simulations. Built with MongoDB Atlas, Voyage AI, and WebSockets, Court Run proves that effective AI collaboration requires intelligent memory and agents that genuinely listen to each other. The platform includes tabs for live simulations and result summaries.

### 68. MonGOD

Incident Copilot is a seeded-RAG assistant for on-call engineers. It uses MongoDB Atlas Vector Search, Voyage embeddings with reranking, and Google Gemini to answer operational questions fast and accurately. Instead of running full retrieval each turn, it builds a reusable “seed” per incident: a summary plus top reranked snippets from runbooks, postmortems, and dashboards. Follow-ups reuse the seed unless topic drift is detected via cosine similarity; then it rebuilds automatically. A React dashboard shows answers, citations, and context with metrics for latency, tokens, seed hits, and drifts. Example: “Kafka consumer lag is spiking—what now?” The first turn retrieves and reranks; later turns answer from cache, cutting latency and token spend while improving focus and factuality. Result: calmer pagers, faster fixes, and reliable, source-linked help.

### 69. GenCache

We've built a seeded RAG system that uses a lightweight knowledge cache to minimize redundant retriever calls. The LLM first tries to answer a query using cached context from previous questions; if it determines that the information is insufficient, it triggers the retriever to fetch new data and updates the cache. This approach allows semantically related or follow-up questions to be answered instantly from the existing cache, reducing latency, cost, and retrieval frequency while keeping responses contextually consistent across a conversation.

### 70. Memory Mirror - Personal Context Trainer

A real-time visualization tool that demonstrates how AI perception dramatically changes when given personal context/memories. 

Built for Problem Statement #3 (Memory-Informed Experiences), Memory Mirror extracts and stores structured memories from user input, then shows side-by-side comparisons of AI responses with and without this context.

Key insight: Users can immediately see why AI fails without memory and succeeds with it. Built by a non-technical founder in 6 hours while "vibe coding" - proving accessible AI development.

Features:
- Real-time memory extraction and categorization
- Visual memory graph with confidence scoring
- Side-by-side response comparison ("The Mirror Effect")
- Memory timeline and type analytics
- One-click demo mode for easy testing

Impact: Demonstrates the critical importance of memory in AI interactions and showcases the potential of memory-informed AI agents.

### 72. Reiko

AI Human Journal - Document your life in a smart way

  The Problem:
  Traditional journaling is tedious and time-consuming. People struggle to maintain consistency, identify patterns in their decisions and outcomes,
  and extract actionable insights from their experiences. Life lessons get forgotten, and personal growth remains unmeasured.

  Our Solution:
  - Conversational Documentation: Users talk naturally with "Alex," an AI companion via video/voice, making daily reflection effortless (10x faster
  than typing)
  - Intelligent Pattern Recognition: Automatically analyzes recurring themes, decision patterns, and behavioral trends from journal entries
  - Semantic Memory Search: Uses MongoDB Atlas Vector Search with embeddings to find relevant past experiences instantly - ask "When did I face a
  similar challenge at work?" and get contextual results
