📦 endee-io/endee

Endee Vector Database

Endee is a dedicated vector database written in C++ that can index and search up to one billion vectors on a single machine. Built to handle heavy AI retrieval workloads and RAG pipelines, it solves the problem of slow search times by optimizing its indexing directly for modern hardware. It compiles down to target specific CPU instructions like AVX512 or ARM's NEON to extract absolute peak performance. The coolest part is that it supports hybrid search, combining dense vector similarity with sparse exact matches and real-time metadata filtering. It is a incredibly fast, self-contained engine for giving your AI applications lightning-fast long-term memory.

📦 rit3zh/expo-morphing-menu

expo-morphing-menu

Build sleek, fluid user interfaces in React Native by turning your standard chat composer into an interactive menu. Instead of letting a traditional pop-up sheet block your app design, expo-morphing-menu uses a spring physics engine to morph the input bar itself. The composer dynamically expands in height, width, and position to become the menu background. It stays perfectly aligned with the mobile keyboard while navigating multiple panels like photos, files, or custom integrations. It offers mobile developers a clean way to handle text inputs, media attachments, and options panels inside a single, unified interface.

📦 hugecatlab/chattutor

ChatTutor

ChatTutor is the interactive learning assistant that finally gives your AI tutor a digital blackboard to sketch on. While standard chatbots get stuck explaining complex math and science using only dry text, ChatTutor gives the AI hands-on control over a dynamic math canvas and interactive mindmaps. When you ask a question, the AI actually draws out formulas, plots geometric shapes, and structures ideas visually, just like a real teacher writing on a whiteboard. It completely changes how you study technical topics. Check out the project to host your own visual AI classroom and make learning feel alive.

📦 xiangyu-cas/codex-canvas

Codex Canvas

Edit images on a local infinite canvas directly inside your Codex conversation. This tool automatically pulls your generated visuals into a dedicated sidebar panel, keeping your workspace organized by project thread. The coolest feature is how you can isolate layers. It separates flat images into independent, movable elements like background, text, and objects, completing the hidden background behind them. You can rearrange these layers on the fly and export the entire canvas group as a Photoshop-ready PSD file. It makes visual asset organization incredibly easy. Give it a spin to bring layered, canvas-style image editing straight into your chat workflow.

📦 hugo-dz/spritefusion-pixel-snapper

Sprite Fusion Pixel Snapper

Generative AI is notoriously terrible at understanding grid-based pixel art, usually producing messy images with drifting resolutions and inconsistent color palettes. That is where spritefusion-pixel-snapper comes in, using Rust and WebAssembly to automatically snap those chaotic, off-grid pixels back into a perfect, clean layout. It detects the native pixel dimensions, aligns the image to a consistent grid, and quantizes the colors into a strict, beautiful palette. Whether you are fixing AI-generated game assets or cleaning up procedural 2D tilemaps, it gives you crisp results instantly. Run it directly in your browser or batch-process folders of images offline using the command line.

📦 cosmtrek/mindwalk

Mindwalk

Mindwalk is the visualization tool that replays AI coding sessions on a three-dimensional map of your codebase. When an AI agent works on your files, reading raw log files makes it incredibly difficult to tell what the assistant actually did or how it explored. This tool builds a deterministic, dark-mode city map of your repository and traces the agent's actions as moving light, turning searches, reads, and edits into glowing paths you can inspect at a glance. It runs completely locally on your machine to analyze your sessions. Check it out to see exactly how your AI assistant thinks.
