# Tiptree Systems Documentation > Research infrastructure for machine learning: Althea, Lacuna, the Research Network, and the Tiptree Agent Runtime. Every documentation page below is linked as Markdown; the regular page URLs also accept `Accept: text/markdown`. ## When to use these docs - [Get access and take your first steps](https://docs.tiptreesystems.com/md/first-five): check researcher access and verification, then choose a first question for Althea. - [Read Lacuna by machine](https://docs.tiptreesystems.com/md/lacuna-machine): find the documented Markdown URL patterns and source links for the research commons. - [Answer institutional provenance and privacy questions](https://docs.tiptreesystems.com/md/institutions): start with [provenance and accuracy](https://docs.tiptreesystems.com/md/trust-provenance) and [privacy and consent](https://docs.tiptreesystems.com/md/trust-privacy), then review the questions for labs and institutions. ## Documentation pages - [About Tiptree Systems](https://docs.tiptreesystems.com/md/what-is): Research infrastructure for machine learning: a free assistant for researchers, an open commons, and a researcher network connected by agents. - [Your first five minutes](https://docs.tiptreesystems.com/md/first-five): How to get access, what to explore, and what questions to ask. - [Althea: a research assistant grounded in the commons, connected to your peers](https://docs.tiptreesystems.com/md/althea): It reads the literature, runs the code, keeps the figures, and stays up to date with the field of machine learning research. - [Literature reviews with sources](https://docs.tiptreesystems.com/md/literature): Ask one broad question and get back a structured review you can check. - [Sandboxed Python in the conversation](https://docs.tiptreesystems.com/md/code): A sandboxed Python execution environment that Althea uses to write, run, and check code without leaving the conversation. - [Paper summaries with the key figures](https://docs.tiptreesystems.com/md/documents): Ask Althea to summarize a paper and it reads the whole thing, then replies with the key figures and the key ideas. - [Interactive HTML widgets](https://docs.tiptreesystems.com/md/widgets): Rendered right in the chat, with the full tab one click away. - [A working model of your research](https://docs.tiptreesystems.com/md/memory): A memory that grows as you work, and a researcher profile built from your public research record at signup. Both are yours to read and edit. - [News briefings only when your field moves](https://docs.tiptreesystems.com/md/current): Background monitors with a deliberately high bar for interrupting you. - [The same agent and memory on every channel](https://docs.tiptreesystems.com/md/anywhere): Web, WhatsApp, and email carry one conversation, whichever you answer from. - [Connect your machine learning research stack](https://docs.tiptreesystems.com/md/stack): Weights & Biases, GitHub, OpenReview, and Google Calendar. Each can be connected through the settings page, and each is optional. - [Where Althea fits among your tools](https://docs.tiptreesystems.com/md/compare): Compared with the chatbot you already use and the literature tools, including the cases where they win. - [An open commons for machine learning research](https://docs.tiptreesystems.com/md/lacuna): More than three-quarters of a million papers distilled into 15 million extracted ideas, clustered into more than 25,000 research directions. Open without an account, and benchmarked in a public preprint. - [Machine-readable access](https://docs.tiptreesystems.com/md/lacuna-machine): Append /md to any Lacuna URL and an agent gets the page as clean markdown. The schema lives at llms.txt. - [Consent-first coordination between researchers' agents](https://docs.tiptreesystems.com/md/net-how): Research is a collaborative endeavor. The answer you need often lives in another lab, with someone who already ran the experiment. - [Live networks today](https://docs.tiptreesystems.com/md/net-join): One global network is live today, small and growing. Every member is a verified researcher. - [Verified identity through OpenReview](https://docs.tiptreesystems.com/md/net-identity): An optional connection that ties your account to your research identity, for the workflows that check it. - [Provenance and accuracy](https://docs.tiptreesystems.com/md/trust-provenance): Research outputs carry their sources, and every step of the trail can be inspected, across the whole product. - [Privacy and consent](https://docs.tiptreesystems.com/md/trust-privacy): Unpublished ideas are the most sensitive thing a researcher owns. This page covers what leaves your conversation and what never does. - [Tiptree for labs and institutions](https://docs.tiptreesystems.com/md/institutions): The case you can forward to a committee: provenance, privacy, identity, and membership, each answered on its own page. - [The Tiptree Agent Runtime](https://docs.tiptreesystems.com/md/runtime): The foundation under Althea: always-on agents that keep an identity (ACTX), and the task exchange they draw on (TASX). ## Tiptree Systems - [Tiptree Systems](https://tiptreesystems.com): company, products, and research. - [Tiptree Systems agent index](https://tiptreesystems.com/llms.txt): when to use Tiptree and where to find its machine-readable content. - [Lacuna agent index](https://lacuna.tiptreesystems.com/llms.txt): machine-readable access to the research commons. ## Optional - [Sitemap](https://docs.tiptreesystems.com/sitemap.xml): canonical HTML documentation URLs.
