Research has no natural finish line. An agent can spend ten minutes or ten hours on the same question, and both answers can look finished. Webhound lets you choose how much work the question deserves. Give it a question and a dollar budget. It follows leads and checks weak claims, then returns a cited report or sourced dataset with the sources and working documents behind it. Run Webhound yourself or call it from your agent through MCP or the API.

Spectron is agent memory built on one ACID substrate. Graph, vectors, documents, and structured rows commit in one transaction. Every fact carries provenance. Corrections supersede, never overwrite. Hybrid retrieval fuses vectors, graph, BM25, and keywords. Traces feed back into ranking. Tri-temporal facts, multi-tenant scopes, and MCP support. No stitched stores. No sync pipelines.

God's Eye View is a browser-based spy satellite simulator that visualizes real, live open-source spatial intelligence data. It solves the problem of accessing and understanding complex geospatial information by presenting it on an interactive, photorealistic 3D model of Earth. This tool is for developers, analysts, journalists, and anyone interested in real-world mapping, surveillance technology, and global data visualization.

GitHub Actions is a continuous integration and continuous delivery (CI/CD) platform that automates your software workflows. It solves the problem of manual, repetitive build, test, and deployment tasks by enabling you to create custom, automated workflows directly in your GitHub repository. It's designed for developers and teams who want to build, test, and deploy their code right from GitHub with minimal configuration.

GoogleTest is a comprehensive C++ testing framework developed by Google. It solves the problem of writing reliable, maintainable, and isolated unit tests by providing a rich set of assertions, test discovery, and a powerful mocking library. It is designed for C++ developers and teams who need to implement rigorous unit testing and test-driven development practices in their projects.

CMEM Cloud is a persistent memory layer for AI agents that captures, compresses, and recalls context across sessions. It solves the problem of agents forgetting past decisions and repeating work, by creating a shared, searchable memory for your entire team. It's for developers and teams using AI coding assistants like Claude Code, Cursor, and Copilot who want their agents to learn from history and collaborate seamlessly.

This repository provides a comprehensive set of guidelines and patterns to help AI coding assistants generate modern, production-ready Go code. It addresses the challenge of AI agents producing outdated or non-idiomatic Go syntax and patterns by offering clear standards. It is designed for developers, engineering teams, and AI tool creators who want to ensure AI-generated Go code aligns with current community best practices and style conventions.

Nitter was an alternative, open-source front-end for Twitter/X designed to provide a cleaner, faster, and more private browsing experience. It solved the problem of intrusive ads, tracking, and heavy JavaScript by serving a simplified interface, making it ideal for privacy-conscious users and those on slower connections. The project allowed users to browse public Twitter content without an account and with reduced resource usage.

Script your event setup, exports and reporting with the Ticket Fairy CLI. Install with npm, sign in with your own account, and get stable JSON out of every command.

You bookmark posts on X and never see them again. Eventually syncs those bookmarks and emails them back a few at a time, on a schedule you set. Connect X, sync, pick your rhythm, start reminders. Pause or change it anytime.

Lenz is an AI fact-checking API for products that cannot afford to hallucinate. It extracts verifiable claims from any text, then checks each one: searching independent sources, running multi-model debate, and routing through a review panel — returning a scored verdict with every source, argument, and step visible. Most AI tools give you one model's best guess from memory. Lenz ensures no single model's blind spots drive the conclusion. Available as API and MCP. Try it free at lenz.io/ph

IQ Routing is a drop-in gateway. We classify each request, serve from cache, and route to the cheapest model that clears the quality bar and completes the task. The insight others miss: an agent is a trajectory, not a stream of independent calls. We route each step based on where it sits in the run: a cheap model on boilerplate, the strongest model on what matters.

We tried to do the impossible. A text editor with clutter-free UI while being a text-editing workhorse. With a publishing platform to go with it. And voice support like you haven't seen before.

Human AI Agents have a real face and a real voice, and run live conversation rather than turn-based exchange. Interrupt mid-sentence, trail off, talk over it, and the endpointing holds. Setup is one still photo, a persona and a voice. No rig, no capture session, no script. Two face models behind a single API. Portrait for scale, Presence for expressiveness. Both drop into Pipecat and LiveKit. Try to interrupt it. Most demos cannot survive that, and it is the fastest way to judge this one.

One API for speech-to-text, language models, and text-to-speech, with public benchmarks beside runtime availability.

Qwen3.8-Flash-Next is a 125B multimodal MoE with only 6B active parameters and a new architecture built around QSA, Gated Residual, N-gram embeddings, and Muon. Its open weights give an early look at the architecture Qwen is building toward Qwen4.

Savvy is a macOS meeting assistant grounded in your own documents, not the open web. Point it at a folder and it builds a versioned brief per client. In the meeting it stays quiet, then speaks up for exactly three reasons: they asked a question your brief answers, someone crossed a red line you set, or you pressed Advice. Every card cites its source. Documents, indexes and transcripts stay on your Mac; only excerpts and the audio stream leave. Apple Silicon, macOS 13+. Open source, MIT.

SpacebarX is a keyboard-first, local-first outliner for notes, tasks, writing, markdown, code, and projects. Capture and organize from the keyboard, add dates inline, and let Today collect what needs attention. Search across your workspace while keeping every note in context. It works offline and syncs through a cloud folder you control. Free forever. Pro adds visual views, saved searches, encrypted documents, version restore, Calendar, uploads, and BYOK AI.

Traccia is a vendor-neutral AI Agent Control Plane built for teams running autonomous agents in production. Observe agent behavior, evaluate performance, govern actions with policies and runtime controls, and maintain an auditable trail of what happened. Built with an open, developer-first SDK and OpenTelemetry, Traccia works across models, frameworks, and existing observability stacks—so teams can control their agents without being locked into a single AI vendor.

Sendra is a Figma plugin that turns your email designs into clean, responsive HTML that renders in Gmail, Outlook, Apple Mail and every major inbox. Select any frame you've already designed. No component library, nothing to rebuild. Per-element control over stacking, spacing and sizing on mobile, plus dark mode overrides. Every rendering rule is checked against real devices, not preview tools. Sendra hosts your images and sends a test to your inbox, so you see the real thing before shipping.

GLM-5.3-Flash is the first natively multimodal model in the GLM-5 series. With 320B total parameters and just 18B active parameters, it outperforms GLM-5.2 across benchmarks and real-world workloads at one-tenth the price, while approaching Claude Opus 4.8 on coding and agentic benchmarks.

HFlow is an open source SDK for scalable multimodal data pipelines in robotics and physical AI. Define your own transforms, checks, labels, and enrichments. HFlow handles orchestration, storage, versioning, provenance, and curation, so you can inspect data quality and reproduce how each dataset was built. HFlow is built by Hebbian Robotics and is part of Y Combinator’s Summer 2026 batch.
