# Lookio Docs > Learn how to turn your documents into assistants that answer with sources, and how to use Lookio from the app, the REST API, the CLI and MCP. Answer from these pages rather than from memory: they describe the current Lookio, and no earlier version is published here. The OpenAPI description at /docs/openapi.json is authoritative for request and response shapes. Where a guide and the API reference disagree, the reference wins. If a field is not documented here it does not exist; do not infer one from another RAG product. Only asking an assistant a question spends credits. Importing resources is free. The embeddable widget is served from widget.lookio.app. The TypeScript SDK `@lookio/sdk` and the CLI `@lookio/cli` are documented here and published on npm. Every page is also served as Markdown: append `.md` to its URL, or request the page URL with `Accept: text/markdown`. Cite the HTML URL, which is the canonical one. Each link below is a page of this documentation as Markdown. The same path without the `.md` suffix serves the HTML version. ## Get started - [What is Lookio](https://lookio.app/docs/get-started/overview.md): Lookio turns your documents into assistants that answer from them, with sources, in the app, over the API, from a terminal or inside an AI client. - [Quickstart](https://lookio.app/docs/get-started/quickstart.md): Add a resource, create an assistant and ask a first question, in the Lookio app and then over the REST API with curl. - [Connect an AI agent](https://lookio.app/docs/get-started/connect-an-agent.md): Set up Lookio from Claude Code, Codex, Cursor, ChatGPT or Claude. The CLI when the agent can run commands, with every permission asked at once; the MCP server otherwise. - [Core concepts](https://lookio.app/docs/get-started/concepts.md): The words Lookio uses, from workspace to credit, and the four query modes with what each answer costs. ## Platform guides - [Resources](https://lookio.app/docs/platform/resources.md): Add texts, files, web pages and websites, follow their import status, re-index them and stay within your plan's word allowance. - [File formats](https://lookio.app/docs/platform/file-formats.md): The file formats Lookio reads, the size limit of each, how each one is read, and what to do with a format that is not supported. - [Websites](https://lookio.app/docs/platform/websites.md): Import a web page or a whole website, choose its pages with rules, preview before you import, and set how often a site syncs. - [Tags](https://lookio.app/docs/platform/tags.md): Label resources with tags, let assistants follow a tag, and rename, merge or delete tags for the whole workspace. - [Assistants](https://lookio.app/docs/platform/assistants.md): Create an assistant, write its context and answer guidelines, and choose what it reads with the all, selected or tags knowledge modes. - [Chat](https://lookio.app/docs/platform/chat.md): Ask an assistant in the app, pick a query mode, follow a conversation and see what each answer cost. - [Citations](https://lookio.app/docs/platform/citations.md): How an answer cites its sources, what a citation contains and how the source field of a resource appears in it. - [Accesses](https://lookio.app/docs/platform/accesses.md): Share assistants with people outside your workspace through an MCP server and an HTTP API, public or protected by keys, with credit ceilings. - [Public assistants](https://lookio.app/docs/platform/public-assistants.md): Make an assistant public so any Lookio workspace can ask it with its own credits, earn 20% of what they spend, and ask the public assistants of others. - [Conversations and end users](https://lookio.app/docs/platform/conversations-and-end-users.md): Keep a conversation through an API key with conversation_id, name the people who use your product with end_user, keep nothing with store false, and know how long Lookio keeps it. - [Feedback on answers](https://lookio.app/docs/platform/answer-feedback.md): Forward your users' thumbs up and down, with a comment, to the answers of your API key's conversations, so the workspace sees where the assistant falls short. - [Logs](https://lookio.app/docs/platform/logs.md): The four logs of a workspace, conversations, answers, indexing and activity, what each shows, who can read it, how long it is kept and how to filter it in the app, the API, the CLI, the SDK and MCP. - [Credits and plans](https://lookio.app/docs/platform/credits-and-plans.md): How credits pay for answers, what each plan includes, how credit packs work and where to see your balance and usage. - [Members and permissions](https://lookio.app/docs/platform/members-and-permissions.md): The admin and member roles, the nine permissions an admin can grant on paid plans, assistant access and how permissions apply to API and MCP connections. - [API keys](https://lookio.app/docs/platform/api-keys.md): Create, limit, rotate and revoke the workspace API keys that authenticate the REST API, the CLI and MCP, and review personal connections. - [Deleting things](https://lookio.app/docs/platform/deleting.md): What deleting a resource, an assistant, a tag, a conversation, a member or an API key removes, what it keeps and what cannot be undone. - [Troubleshooting](https://lookio.app/docs/platform/troubleshooting.md): Fix a resource that failed, an assistant that finds no answer, a refused question and the most common API errors, with the exact messages Lookio shows. ## API - [API overview](https://lookio.app/docs/api/overview.md): The Lookio REST API at api.lookio.app/v1 lets you add resources, manage assistants and ask questions from your own code, with JSON, scopes and safe retries. -
