github.com/sanity-io/litter ↗Nowness is an autonomous AI lab that runs itself — on local models, on one machine, around the clock. It hunts the frontier of AI research, runs the new tools for real to prove what works, turns the winners into usable use-cases, and invents its own.
Finds the newest AI research and tools the moment they appear.
Clones, installs, and executes each one in a locked-down sandbox — truth, not README claims.
Turns what actually works into real, usable use-cases.
Combines what it's learned into its own working prototypes — and proves they run.
One thing it proves: 1,420 AI repos it actually ran, and a third don't work.
Everyone judges AI by the demo. Nowness runs the code — and only surfaces what's real.
Paste any public GitHub repo and your email. Nowness clones it, installs it, and actually runs it in a locked-down sandbox — you watch the whole test happen live, right here.

Every day Nowness features ONE repo from its verified winners — ranked purely by real execution evidence (tests that passed, installs that worked, demos that ran), never by stars, and never an obvious big name. A fresh verified gem, daily.
A context management library for Pydantic AI agents that handles long-running conversations by automatically summarizing history or using a sliding window.
Summarization for Pydantic AI is a context management library designed to handle long-running conversations for AI agents. It manages context overflow by automatically summarizing history or employing a sliding window technique. The library preserves critical tool-call pairs while providing token tracking. Lab testing confirmed the core library is complete and successfully passed all tests.
This project earns its spotlight by solving the practical problem of context window overflow and high token costs. It allows customer support bots and code assistants to retain key details while discarding routine noise. By being integrated into the official Pydantic AI ecosystem, it provides a reliable way to maintain history in high-throughput applications.
Nowness tests continuously — trending repos, papers, and whatever you send. This is live from the sandbox.
Every card below was actually executed by the lab — under-the-radar repos that installed clean and did what they claim, verified in the sandbox, not guessed from the README. From 3,494 repos tested so far.
