Quick Answer
Vibe Story is VibeDoctor's plain-English narrator for your codebase. The moment a scan finishes, it auto-plays an animated walkthrough of what your app does - module by module and function by function - narrated step by step from your code's own comments. Every step shows the function, its file and line, and the comments from inside it, turned into plain English. No graphs to decode, no source reading required. It is the fastest way for a vibe coder to finally understand what their app actually does.

You vibe-coded an app. Could you explain what it actually does?
Most people can't, and that is fine - AI wrote most of it. You prompted, the agent generated, the app worked, you shipped. But when something breaks, or you want to add a feature, or an investor or a teammate asks how it works, "the AI built it" is not an answer. You need to actually understand your own code, and the code is the one thing you never read.
This is the quiet tax of vibe coding. You gained speed and lost the mental model. The AI knows what it built because it built it. You do not, because you were describing outcomes, not reading implementations. Existing code tools do not rescue you here - they hand you dependency graphs, finding lists, and call hierarchies built for engineers who read code all day. They assume the very fluency you skipped. Vibe Story is the opposite. It does not ask you to read anything. It talks to you.
What is Vibe Story?
Vibe Story is a plain-English explainer for AI-generated code. Connect a GitHub repo, run a scan, and the moment it finishes your app starts narrating itself: an animated walkthrough of what your code does, one function at a time, in sentences a non-coder can follow.
It opens on a module - a meaningful part of your app like checkout, auth, or your API - and plays through its key functions on a timeline, the way the demo above plays on its own. Each step is one function: a plain-English headline pulled from the comment above it, the function name and file line so you can jump to the real code, and the function's own inline comments expanded underneath as the detail. Press Pause to stop on a step, switch to Read to scan it yourself, or move to another part of your app from the Modules breadcrumb.
It is built on the same structural map that powers Vibe X-Ray: every function in your repo and how they call each other. Vibe Story rides that map and adds the one thing the graph was missing - a human-readable line for each step.
How it works (and why it never makes things up)
Vibe Story picks a meaningful module and walks its key functions in order. The headline for a step is the comment you or your AI wrote directly above that function. Expand the step and you see that function's own inline comments, in order, as the detail - so a twenty-line comment block your AI left behind becomes a readable list instead of buried text. Where a function has no comment, Vibe Story falls back to a plain-English version of its name and tells you so, so you always know which words are yours and which were inferred.
- Build the payment intent.
- Confirm and store the receipt id.
Deterministic by design. Every line of substance is your own comment or your function name - Vibe Story only adds the numbering and connecting structure. There is no language model writing the story, so there is nothing to hallucinate. Comments are shown as captions, never judged - no severity, no score, no false positives. And because it is a best-effort read, every step links the real function and file line so you can open the actual code.
The walkthrough opens with a simple line - "Here's what Checkout does" - and a quick health read of that module, then plays each function as a step. The progress bar scrubs down the timeline and each step lights up in turn. The only words Vibe Story authors are the numbers and the structure. Every sentence that matters is yours.
Press play, or read it yourself
The walkthrough plays itself the moment the page loads - no module to choose, no graph to expand, no file tree to click through. Hit Pause to stop on a step, or switch to Read to scan the whole module at your own pace. Browse a different part of your app from the Modules breadcrumb at the top. Want the real code behind a step? The function name and file line are right there (src/checkout/payment.ts:91) - click straight through. Want the engineer's view of how everything connects? The full Vibe X-Ray map is one click away.
Vibe Story vs Vibe X-Ray: two ways to see the same code
They are siblings, not rivals. X-Ray is for exploring the map yourself; Story is for having the app read itself to you. If you read code, you will live in X-Ray. If you do not, Story is your front door - and you can jump from one to the other at any time.
Watch your code change over time
Every scan snapshots the story. The next time you scan, Vibe Story can tell you what moved: a step that is new since last time, a function whose comment changed, a comment that got deleted, or a step that disappeared because the AI removed the function. For a project where your agent edits a dozen files in a single session, that is a plain-English changelog of what it actually did - not what you asked it to do.
Works across your whole stack
Vibe Story understands around 20 languages out of the box, because it reads your code's structure, not any one framework. A Python API and a Next.js frontend tell the same kind of story - the module headline, the function steps, and the captions all come from your code regardless of syntax.
| Stack | Languages Vibe Story narrates |
|---|---|
| Web frontends | TypeScript, JavaScript, JSX / TSX, Vue, Svelte |
| Backends and APIs | Python, Go, Java, Ruby, PHP, C#, Kotlin |
| Systems and native | Rust, C, C++, Swift, Scala |
| Scripting and other | Dart, Elixir, Lua |
Comment culture varies by language - Python and Java codebases tend to be doc-heavy, Go tends to be terse - so how many steps come from your own words versus from function names will differ. That is honest signal, not a gap. Either way, the walkthrough plays.
Who Vibe Story is for
- Vibe coders who want to understand their own app. You built it with Cursor, Bolt, Lovable, v0, or Claude Code and never read the result. Story is the first time you see what you actually shipped.
- Founders heading into a demo or due diligence. Be able to explain your product's core flow in plain English before someone technical asks.
- Anyone inheriting an AI-generated codebase. Get the gist of how a module works in thirty seconds before you start reading files.
- Solo builders onboarding a collaborator. Hand them the walkthrough instead of an hour of "so this calls that ..."
Why it matters
The first time you watch your own app explain itself in thirty seconds, something clicks. You finally see the shape of what you built - the work your code actually does, in your own words - and the gaps you did not know were there. Understanding your code stops being a chore you keep postponing and becomes something that happens automatically every time you scan. Run a free scan and meet your codebase.
FAQ
What is Vibe Story?
Vibe Story is VibeDoctor's plain-English narrator for your codebase. The moment a code scan finishes, it auto-plays an animated walkthrough of what your app does - module by module and function by function - narrated step by step from your code's own comments. Every step shows the function, its file and line, and the comments from inside it, in plain English. No dependency graphs to decode, no source reading required.
Does Vibe Story use AI to make things up?
No. The narration is deterministic. Every line of substance is a comment you (or your AI tool) wrote in the code, or a plain-English version of the function name. Vibe Story only adds the numbering and structure. It does not invent behavior, and comments are shown as captions only - they are never scored or flagged. Because it is a best-effort read of your code, every step links the real function and file line so you can open the actual code.
What if my code has no comments?
The walkthrough still plays. Where a function has no comment, Vibe Story turns the function name into a readable phrase (getUserById becomes "get user by id") and labels that step as derived from the name, so you always know which lines came from a real comment and which were inferred.
How is Vibe Story different from Vibe X-Ray?
Vibe X-Ray is an interactive map you explore yourself - modules, files, symbols, and a dependency graph for people who read code. Vibe Story is the opposite experience: it plays your app back to you in plain English. Story is built on top of X-Ray's structural map, so it is a sibling, not a replacement. The full X-Ray map is always one click away.
Which languages does Vibe Story support?
Around 20 languages out of the box, including TypeScript, JavaScript, JSX / TSX, Python, Go, Java, Rust, C#, Kotlin, Ruby, PHP, Swift, C, C++, Vue, and Svelte. It reads your code's structure rather than any single framework, so a Python API and a Next.js frontend tell the same kind of story.
Is Vibe Story free?
Yes - your first walkthrough plays free, including for anonymous and free-plan users. Run a scan and your app explains itself. More modules and sharing are available on paid plans.
