Stop guessing which LLM to use. Upload your data, compare 50+ models, and see quality, cost, and speed side by side. Pick the best model for your use case without manual testing or generic benchmarks.

Record a memory or import an old voice note. Retold keeps the real voice and turns the story into a hand-drawn film and readable book. The sketches follow the people, places and little details as they are spoken, then every memory is kept together on your family shelf.

PostBox turns the MacBook notch into a drag and drop poster for the work you make. Drag an export in, write the caption once, and post to X, Bluesky, Threads, LinkedIn, Dribbble, Instagram, Threads, Pinterest Behance and Cosmos at once.

It’s a local, PR-like code review app that works directly with your working tree. You can review committed, staged, unstaged, and untracked changes, leave inline comments, and organize the work into actual reviews without having to push anything anywhere. You connect whatever AI you're using through MCP and have a coherent experience without all the mundane copy-pasting. All comments live in threads attached to specific code changes, so it’s easy to follow what’s going on over time.

Fast, elegant movie tracking. Search a film, rate it, queue it, rank what to watch next. The Letterboxd alternative.

Type a prompt, get a buildable brick model. The AI (image + mesh gen) is just the front door. The real work is the brick-placing engine: voxelizing the shape, tiling it with actual LEGO-compatible parts, staggering seams for strength, running structural analysis (gravity load) to catch weak points, then refining with slopes and tiles (currently a 55 part brick library). You get a realldr file, parts list, and step-by-step PDF instructions. Renders below done with the Mecabricks Advanced add-on.

Experiential is the open source, zero markup gateway for BYOK, self-hosted and 1000+ marketplace models. It learns from your traffic to cut costs, recommend better models, and train a specialized model you own.

Reflexio makes AI agents better with every interaction. When users correct an agent, a path fails, or something works particularly well, Reflexio turns that experience into behavior the agent can reuse next time. Instead of leaving valuable lessons buried in logs, your agent continuously learns what to repeat and what to avoid — with every learning visible, testable, and reversible. Reduce task failure rate by more than 30%, while saving tokens by more than 60%.

Glance at traffic. Leave on time. CommuteBar puts live commute times visibly on your Mac menu bar, no app-switching required. Save multiple destinations like office, school, gym. Schedule automatic switching for recurring commutes and get leave soon / leave now indicators and optional notifications. You also get route comparison, delayed traffic alerts and different travel modes.

Every entry you write today locks at the time that you configured — 8pm by default. Once it locks, that's it: no editing, no rewriting history, no quietly polishing what you actually felt in the moment. Just an honest, raw, and unfiltered record of your day. Entries sync across your devices with your own private iCloud and never with a first/third-party server. When typing is not enough, record a squope (square video) or an audio note. at8pm is free to download (up to 2 entries per day).

HyperProbe is how backend teams debug production issues they can't reproduce locally. Instead of adding a log line and waiting on a deploy, we let Claude Code, Codex, or Cursor drop read-only probes into a running service and capture the variable state that was never recorded. From there your agent debugs like it has a local repro, closing the bug in one sitting.

Ponytail is a plugin that makes coding agents write the least code that works. Before adding anything, it checks whether the change is needed, already exists, or can use the stdlib or a native API. Same behavior, fewer lines to own.

Open source feature flags as markdown files in your repo: the flag, the reason, the decision in one file, reviewed in a PR. One command, no account, so your coding agent can finish the install. A/B tests wait in the same files until you have traffic.

RenoDX is an open-source framework for creating targeted graphics mods for DirectX games. It solves the problem of generic, one-size-fits-all post-processing by allowing mods to be built around individual games' rendering pipelines for precise upgrades like HDR output and shader replacement. It's for modders and players who want to enhance specific games with deep, persistent, and game-aware visual modifications.

OpenCode is an open-source AI coding agent that helps developers write code directly in their terminal, IDE, or desktop application. It solves the problem of fragmented AI coding assistance by integrating with any model provider, including local models, and works with existing subscriptions like GitHub Copilot and ChatGPT. It's built for privacy-first environments and is designed for developers who want a flexible, powerful, and open-source coding assistant.

Miles is an open-source reinforcement learning framework designed to make training large language and vision models simple, efficient, and stable. It solves the engineering complexity of agentic RL for post-training tasks like SFT, RL, and distillation, enabling faster iteration and stable long runs. It's built for AI labs and enterprises working with frontier models, offering proven scale, extensive hardware support, and integrations with popular agentic environments.

This repository is a collection of public exploit Proofs-of-Concept (PoCs) and vulnerability research write-ups for unreported security flaws. It aims to lower the barrier to entry for security research by providing concrete, real-world examples for study and learning. It is intended for aspiring security researchers, bug bounty hunters, and students looking to understand vulnerability discovery and exploitation techniques in a practical, hands-on context.

Gemini 3.8 Flash and Gemini 3.8 Flash Cyber bring next-generation intelligence to agentic workflows and cybersecurity. Built for long-horizon coding, multi-step reasoning, autonomous tasks, and vulnerability detection, they deliver stronger performance at Flash speed and low cost.

Book AI coding agents on a real calendar. Clockwork runs them unattended in sandboxed git worktrees on your Mac, pauses for approval when something looks risky, and files a report with the actual dollar cost. Bring your own key or ride your existing subscription. Schedule recurring agent jobs on a real calendar, run them unattended in isolated sandboxes, and review honest reports.

Chalked is the reply layer for Mac. Open a supported conversation and it prepares what you would actually say from the visible thread, live calendar and sourced working context. Press Tab to insert, hold fn to change the intended outcome by voice, then review and send yourself. Accepted or edited communication can become inspectable evidence, so later replies start smarter. Voice is optional. Nothing auto-sends.

Review PRs from inside your running app: switch branches from an in-page widget and compare worktrees side by side. Loopback-only, zero dependencies.

Inline is a thread-based chat app for all work, with your team and agents.
