Build a Documentation Site with AI

Published February 28, 2026

Good documentation is the difference between a tool people adopt and one they abandon after five minutes. But building a docs site has always felt like an unreasonable amount of work: choose a static site generator, learn its templating system, fight with sidebar configuration, style the code blocks, set up search. For a small API or open-source project, the documentation tooling can take longer to set up than the project itself.

AI coding agents eliminate that overhead. You describe your API, your endpoints, and the structure you want. The agent builds a complete documentation site with sidebar navigation, syntax-highlighted code examples, and a clean layout that developers actually enjoy reading. AccessAgent.ai's API was built for AI agents -- deployment is one API call.

Why Documentation Matters

Developers evaluate tools by their docs. If they cannot figure out how to authenticate in under two minutes, they move on. If the code examples have syntax errors, they lose trust. If the docs are a single enormous README, they cannot find anything. Good documentation is structured, scannable, and full of working code.

A static documentation site solves all of these problems. Sidebar navigation lets developers jump to the section they need. Dedicated pages for each topic keep content focused. Code blocks with proper formatting make examples easy to copy and use. And because it is static HTML, it loads instantly.

What Your Agent Builds

Sidebar navigation. A persistent sidebar with grouped sections: Getting Started, Authentication, Endpoints, Errors, SDKs. Click any item and jump straight to that page. The current page is highlighted.
Code blocks with syntax highlighting. Inline code styling with proper monospace fonts, background contrast, and color-coded syntax. Examples in multiple languages (curl, JavaScript, Python) with tab switching.
Responsive layout. On desktop, the sidebar sits on the left with content on the right. On mobile, the sidebar collapses into a hamburger menu. Content fills the full width.
Search. A client-side search bar that filters pages by title and content. No backend required -- the agent builds a simple JavaScript index from your documentation content.
Anchor links. Every heading gets an anchor ID, so you can link directly to specific sections. Essential for support conversations and GitHub issue references.
Consistent styling. Every page shares the same header, sidebar, and footer. The design is professional and focused, with no visual clutter competing with the content.

Build It Now

This prompt builds API documentation for a fictional task management API called "TaskAPI." Replace the endpoints and descriptions with your own API to get production-ready docs.

Example Prompt

Build a documentation site for "TaskAPI" — a REST API for task management. Create a multi-page static site with sidebar navigation. Pages to create: 1. index.html — Overview: what TaskAPI does, base URL (https://api.taskapi.dev/v1), link to quickstart 2. quickstart.html — 3-step quickstart: get API key, create a task, list tasks. Include curl examples. 3. authentication.html — API key auth via Authorization header. Show examples in curl, JavaScript (fetch), and Python (requests). 4. tasks.html — Full CRUD endpoints: - POST /tasks — Create task. Body: { title, description?, priority: "low"|"medium"|"high", dueDate? }. Returns 201 with task object. - GET /tasks — List tasks. Query params: status (open|done), priority, limit (default 20), offset. Returns array. - GET /tasks/:id — Get single task. Returns 404 if not found. - PATCH /tasks/:id — Update task. Partial body. Returns updated task. - DELETE /tasks/:id — Delete task. Returns 204. For each endpoint show: method, path, description, request body/params, example request (curl), example response (JSON). 5. errors.html — Error format: { error: { code, message } }. List common codes: 400, 401, 403, 404, 429, 500 with descriptions and example responses. 6. webhooks.html — Webhook setup: POST /webhooks with { url, events: ["task.created", "task.completed"] }. Show payload examples. Sidebar: - Group into sections: "Getting Started" (Overview, Quickstart), "API Reference" (Authentication, Tasks, Webhooks, Errors) - Highlight current page - Collapsible on mobile with hamburger icon Design: - Dark theme: background #0f0f17, sidebar #0a0a12, text #b0b0c8, headings #ffffff - Code blocks: background #0a0a10, border #1a1a2a, monospace font - Accent color #60a5fa for links, current sidebar item, method badges - HTTP method badges: GET=green, POST=blue, PATCH=yellow, DELETE=red - Max content width 720px, sidebar 240px - System font stack, fully responsive Include a simple client-side search that filters sidebar items by title. Zip all files and deploy to AccessAgent.ai with site name "taskapi-docs". Read the guide at https://accessagent.ai/api/guide and follow it to create and deploy the site.

Adding New Endpoints Later

Documentation is never finished. As your API evolves, you need to add new pages and update existing ones. Here is how to extend your docs site with a new section:

Update Prompt

Add a new page "labels.html" to the TaskAPI docs site: Endpoints: - POST /labels — Create label. Body: { name, color: "#hex" }. Returns 201. - GET /labels — List all labels. Returns array. - DELETE /labels/:id — Remove label. Returns 204. - POST /tasks/:id/labels — Attach label to task. Body: { labelId }. Returns 200. - DELETE /tasks/:id/labels/:labelId — Remove label from task. Returns 204. Include curl + JavaScript examples for each endpoint. Add "Labels" to the sidebar under "API Reference" on all pages. Update the search index. Re-zip everything and update the site on AccessAgent.ai. Read the guide at https://accessagent.ai/api/guide and follow it to create and deploy the site.

Tips

Organize by task, not by object

Developers come to docs with a goal: "I want to create a task," "I need to set up webhooks." Organize your sidebar around what developers want to do, not around your internal data model. A page called "Tasks" that covers all CRUD operations is more useful than separate pages for "Task Object," "Task Endpoints," and "Task Parameters."

Include working code examples for every endpoint

Every endpoint should have at least one complete, copy-pasteable example. Show the request and the response. Use realistic data -- not "string" and 0, but "Fix login bug" and "high". Developers often copy your example and modify it. If your example works, their modified version probably works too.

Add anchor links to every heading

When someone asks a question in your support channel, you want to link them to the exact section that answers it. Every h2 and h3 should have an id attribute. The agent can generate these automatically from heading text. A link like /tasks#create-task is far more helpful than "check the Tasks page."

Keep the sidebar shallow

Two levels of nesting is the maximum. If your sidebar needs three or four levels of depth, your documentation structure is too complex. Split large pages into focused ones, or group related pages under a clear section heading. The goal is for any page to be reachable in two clicks from the sidebar.
