AI tool

PageIndex is a vectorless, reasoning-based RAG engine for long documents. The repository shows a Python SDK, quickstart code, model recommendations, and benchmark claims for document retrieval without vector DBs or chunking.

Open source inference engine for agents that self-tunes on the user’s hardware to run open models faster, with desktop app support and one-click connections to popular agents.

Cortex is a macOS system monitor that groups processes into apps, tracks 30 days of history, and surfaces Apple Silicon metrics like Neural Engine, local model usage, memory, battery, and fans. It also includes an on-device assistant and a model fit advisor for AI workloads.

A public scoreboard that tracks whether apps use your data to train AI models, whether you can opt out, and what it costs to refuse. It also shows policy changes over time and lets users build a personal exposure report in the browser.

Managed desktop environments for computer-use agents, with application monitoring, artifact checkpoints, and recovery controls. The page shows KiCad and FreeCAD support, an API/SDK, usage flow, pricing, and a quickstart example.

GasPeek compares real-time USDT transfer fees across blockchains like Tron, Ethereum, Polygon, Solana, BNB Chain, TON, Aptos, Avalanche, and Polkadot, helping users choose the cheapest network before sending.

A PostgreSQL helper that previews INSERT, UPDATE, and DELETE effects as row-level proposals before applying them, aimed at AI agents and other write workflows.

Knowl is a persistent memory server for AI coding agents. It stores facts with provenance, supports supersession when information changes, and integrates with clients like Claude Code, Cursor, and Codex through MCP.

Tako VM is a secure file system and Python execution layer for AI agents, with gVisor-isolated containers, queued jobs, retries, replay, and a Python SDK/REST API.

Epho is an API for running coding agents like Claude Code, Codex, or OpenCode in the cloud. It takes a prompt and repo context, then streams back the agent’s work over SSE.

Marginal is an LLM cost-tracking and observability product that attributes spend by customer, feature, model, or any custom field. The page shows a dashboard, pricing logic, SDKs, HTTP API access, and example integrations for TypeScript and Python.

An MCP server and CLI for shared notebooks for agents, with pull/commit workflows, durable S3 storage, and text-based conflict handling.

An MCP server for AI agents that stores persistent long-term memory in OKF format and searches it with SQLite FTS5.

Primus is an autonomous AI researcher that hypothesizes, reads papers, writes code, runs experiments on compute, and drafts research papers. The page shows example tasks, published-paper claims, waitlist access, and positioning for ML research workflows.

BoundaryBench is an open-source benchmark for coding agents running under hardened sandbox policies. It compares harnesses like Claude Code, Codex, Terminus 2, and Grok on Terminal-Bench tasks and includes quickstart, policy controls, and result export tools.

MCP server that lets AI agents control labgrid-managed embedded hardware labs through 47 tools, including power, console, flashing, muxing, SSH, and place management.

A local-first Node.js utility that redacts emails, phone numbers, paths, secrets, URLs, and other identifiers from LLM prompts, then rehydrates responses locally using session-based mappings.

An interactive browser city that visualizes how an LLM works, with live transformer mechanics such as tokenization, attention, KV cache, residual stream, and sampling.

Free hands-on labs for prompt injection and LLM security training, with real models, a context trace view of assembled prompts, and a multi-level Gauntlet challenge.

A curated-taste API for architecture, art, design, and photography, with both REST endpoints and a native MCP server for AI agents. It offers search, similarity, provenance, and taste metadata across 2,500+ hand-selected projects, plus free keys and documented pricing.

A fast, private, self-hostable AI chat app for OpenRouter. It supports bring-your-own-key usage, model selection across many providers, attachments, web search, portable history, and both hosted and self-hosted deployment.

LLMIntel is a runtime telemetry and cost dashboard for LLM apps. The live demo shows spend by model, API key, environment, and tag, plus at-risk spend for retiring models and optimization suggestions.

A free public API for LLM pricing, specs, benchmarks, and cost calculations across 1,000+ models. It offers no-auth endpoints, CORS support, an OpenAPI spec, and a LiteLLM-compatible cost map that refreshes daily.

Open-source Chromium fork that aims to keep browser automation and scrapers from being blocked by patching fingerprint surfaces inside the engine. It connects over CDP and is positioned as a drop-in replacement for Playwright, Puppeteer, and other CDP clients.
