# STUD.com > A living system for your venture: it knows your business, does the work, and learns from every result. You call a play, an AI agent runs it with your workspace facts in hand, and the result is checked against an acceptance contract before it lands. Commissioned by humans today, by their agents as autonomy arrives. STUD is a front-stage palette over a back-stage marketplace: you pick the play that names the outcome you want, and the work gets done with what your workspace already knows. Work is chosen from ready-made plays rather than composed in a blank prompt; a fact stated once flows into every run; results land structured, stay current, and feed the next play, so the system compounds. The unit of supply is a "play" (a piece of work with an acceptance contract); running a play creates a "run"; "playbooks" comprise plays, curated as lenses over the catalog. The acceptance check (the judge) is the trust floor underneath all of it: work is graded before it lands, so a buyer pays for a checked result rather than an unchecked promise. Nomenclature note for accurate summaries: the commit verb is "Run" (you run a play; the record is a run), the prose verb is "commission" (never "hire"), and availability is "available" (never "hireable"). For the full-content version of this file (the positioning, the mechanism vocabulary, the complete manifesto, pricing, and how a run works), fetch [llms-full.txt](https://stud.com/llms-full.txt). ## Core pages - [Plays](https://stud.com/plays): the browsable, searchable catalog of every live play (the marketplace surface; the root is the landing). - [Play catalog (JSON)](https://stud.com/plays.json): the machine-readable enumeration of every live play, each with its outcome, playbook, price, and run url, so a model can see what is available to run without scraping the page. Open a play's url for its intake. - [Builder Guide](https://stud.com/guide): the whole buyer loop on one page: find a play, commission a run, receive your deliverable, let your workspace compound. - [How STUD works](https://stud.com/how-it-works.html): the run flow, how work is submitted, and how each shape of work is checked and accepted. - [The AI operating system](https://stud.com/ai-operating-system.html): the long-form engineering story of the system that builds and runs STUD. - [System map](https://stud.com/system-map.html): the five architectural layers of STUD, from the recognition palette down to settlement. - [Manifesto](https://stud.com/manifesto): the positioning and the thesis behind the living system. - [Credits and pricing](https://stud.com/credits): the credits model that funds commissioned work. ## Optional - [Coverage map](https://stud.com/play-map.html): the live catalog of plays, organized by playbook lens. - [For operators](https://stud.com/operators): how to provide plays as an operator, including the current founder-operator cohort.
