Explain My BuildEnd-user guide vs developer docs
Last updated: July 26, 2026
An end-user guide tells the people who use an app how to do tasks, in plain language. Developer docs tell engineers how the code works: architecture, APIs, and internals. Same product, opposite readers, so a tool built for one rarely produces the other.
What's the difference between an end-user guide and developer docs?
The difference is the reader. An end-user guide is written for someone who wants to use the app, sign up, complete a task, fix a common problem, in plain language, no code. Developer docs are written for someone who wants to work on the app: architecture, APIs, data models, and setup.
Because the readers are so different, the contents, examples, and tools diverge. Here's the side-by-side.
| End-user guide | Developer docs | |
|---|---|---|
| Audience | People who use the app | Engineers who build it |
| Answers | "How do I do X?" | "How does X work / how do I call it?" |
| Contents | Tasks, steps, screens, FAQs | Architecture, API reference, data models, setup |
| Example | "How to invite a teammate" | "POST /invites request schema" |
| Assumes coding knowledge | No | Yes |
| Tools that make it | Scribe, Guidde, Supademo, Explain My Build | Mintlify, DeepWiki, Swimm, GitBook |
What goes in an end-user guide?
An end-user guide contains the tasks your users actually perform, written so a non-technical person can follow them. Typical sections include getting started, the core workflows ("create a project," "share a report"), account and billing basics, and a troubleshooting/FAQ list.
It never assumes the reader can read code. Screenshots or short steps beat a class diagram. The test of a good end-user guide is simple: can a first-time user complete the main job without asking you? If your users keep emailing you the same questions, your end-user guide is missing or incomplete.
What goes in developer docs?
Developer docs contain what an engineer needs to understand and extend the system. Typical sections include an architecture overview, an API reference (often generated from an OpenAPI spec), data models, environment setup, and internal conventions.
This is exactly what the code-doc tools are built for, and they're good at it. Mintlify renders a polished docs site and interactive API reference from your repo. DeepWiki auto-generates a per-repo wiki with architecture diagrams and a code chat. Swimm keeps code-coupled docs in sync as the code changes. GitBook hosts a maintained knowledge base with Git sync. All aimed at engineers. See Explain My Build vs Mintlify, DeepWiki & Swimm.
Why code-doc tools can't produce the end-user artifact
Code-doc tools can't produce an end-user guide because they're optimized for the wrong reader. They summarize how the code is structured, functions, modules, endpoints, which is precisely what a user doesn't care about. Translating "the code has an /invites endpoint" into "here's how to invite a teammate" is a different task with a different audience, and these tools don't attempt it.
That's the gap Explain My Build fills. It reads the same code the dev-doc tools read, then writes for the user: an end-user guide, plus a founder runbook and a code-verified fix-list. Every claim is cited to real code, and anything it can't verify is flagged or refused. It's the one code-reader whose output is aimed at the people who use the app, not the people who build it.
The honest limitation
Because it targets users and the founder, Explain My Build is not a replacement for developer docs. If your engineers need an API reference or deep architecture docs, use a tool like Mintlify or Swimm for that. And Explain My Build's guide is AI-generated from code, so you should review it before publishing, rather than captured from your live screens.
Frequently asked questions
What is the difference between an end-user guide and developer documentation?
An end-user guide tells people how to use the app in plain language (tasks, steps, FAQs). Developer docs tell engineers how the code works (architecture, APIs, data models). Same product, different readers, so different tools make each.
Can Mintlify or DeepWiki make an end-user guide?
No. Mintlify, DeepWiki, Swimm, and GitBook produce developer documentation, they describe how the code and APIs work. For a plain-English guide your customers read, use Explain My Build, which reads code but writes for end users.
Do I need both an end-user guide and developer docs?
It depends on your team. If you have engineers and an API, developer docs help them; if you have customers, an end-user guide helps them. A solo founder with users usually needs the end-user guide first, which Explain My Build generates from your code.
Which tool makes an end-user guide from my code?
Explain My Build is the tool that reads your source code and produces an end-user guide (plus a founder runbook and fix-list). Screen-recording tools like Scribe or Supademo also make user guides, but from a recording of a finished app, not from code.
