FrameShift video editing demo thumbnail

FrameShift

FrameShift is essentially a "Canva for video editing"; upload a video, select any object with SAM 2, preview an edit, and FrameShift will propagate the approved result across every frame using RAFT optical flow, keeping that spatiotemporal understanding throughout every frame.

Meta Harness team photoMeta Harness autonomous agent evolution dashboard

Meta-Harness

Self-improving infrastructure layer for coding agents that autonomously proposes, evaluates, and rewrites agent harnesses based on real execution traces. Built as composable state machines, it transforms harness optimization from a linear iteration loop into a branching search process with sandboxed evaluation, deterministic checkpointing, and time-travel forking.

Rainbolt.ai geolocation demo thumbnail

Rainbolt.ai

Rainbolt.ai is an AI-powered geolocation system that uses CLIP embeddings, Pinecone vector search, Gemini reasoning, and Mapillary verification to predict where a photo was taken. It streams its reasoning live, highlights visual clues directly on the image, and displays the final prediction with sourced reference imagery on an interactive globe.

CyberSea defense intelligence demo thumbnail

CyberSea

An AI-powered defense intelligence platform that combines interactive 3D military equipment analysis with Canadian Arctic maritime patrol simulations. It uses VLMs to identify components, generate tactical assessments, and visualize threats, trade routes, mission events, and strategic infrastructure on a real-time globe.

DeltaHacks XII Winner

Protosynthesis workflow automation demo thumbnail

Protosynthesis

A no-code API workflow automation platform that lets users connect 23+ services through a visual interface. It executes workflows as validated DAGs, streams block-level progress, and uses AI to recommend nodes, validate connections, and optimize automation pipelines.

VibeTrade agentic trading terminal demo thumbnail

VibeTrade

VibeTrade is a real-time BTC trading terminal powered by an agentic LLM, live market data, and a voice-first interaction pipeline. It ingests multiple data streams, computes a risk score every second, and uses a LangGraph agent to inspect market conditions, analyze sentiment, and execute paper trades through Alpaca.

Ignition Hacks VI Winner

RouteTO crime-aware navigation demo thumbnail

RouteTO

A crime-aware navigation platform that evaluates multiple Toronto routes using geospatial crime data, OSRM pathfinding, and dynamic risk scoring. It visualizes incidents through clusters and heatmaps, compares routes by safety, distance, and duration, and recommends the lowest-risk path in real time.
