Local · AI-powered · Approval on every edit

Build your static website through natural conversation.

MyMonk opens a folder of plain HTML, JS, CSS, and images on your computer and lets an AI read, preview, and edit your site — including converting image mockups to working pages. No upload. No cloud. Fully local.

How it works

Three steps. Up and running in a minute.

MyMonk is a single page that runs in your browser. You point it at a folder of HTML/CSS, and it becomes the editor for that folder.

01

Open a folder

Pick any folder on your computer. MyMonk reads it directly — no upload, no copy.

02

Chat what you want

Click an element in the preview. Describe a change. The AI plans edits and proposes them.

03

Preview, approve, snapshot

See the diff and a side-by-side preview before anything is written. Snapshot and accept in one click — or reject with a note so the AI can try again.

Features

Built so you stay in control.

Every choice in MyMonk leans toward letting you keep your work, your files, and your model.

Local files, never uploaded

Uses the browser's File System Access API. Reads and writes happen on your disk. Nothing is shipped to a server.

Nothing reaches MyMonk

Not your keys, not your requests. Everything stays between your browser and the AI provider you chose. We don't proxy, log, or see any of it.

Click an element, ask for changes

Point at a heading or block in the preview. The AI sees the selector and the surrounding context — no guessing.

Drop in screenshots and references

Paste a screenshot, drag a moodboard onto the chat, or click the paperclip to attach a logo. The AI sees the image alongside your message — and can pull images already in your folder into context when you mention them.

Generate images right into the folder

Ask for a hero illustration, a placeholder, or a stand-in product shot. The AI produces a PNG with OpenAI's gpt-image-1 or Google's Imagen 4 — square, landscape, or portrait — and shows it for approval before writing it to your folder.

Mockup in, working page out

Attach a screenshot, a Figma export, or a hand-drawn layout and ask for it as a real page. The AI writes the HTML and CSS to match, then generates any images the design calls for — hero art, product shots, icons. Every file waits for your approval before it's written.

Diff and approve every change

Edits, creates, deletes, renames, moves, and copies all pause for explicit Accept or Reject. Nothing touches disk without you.

Visual HTML diff, side by side

For HTML edits you don't just see code. MyMonk renders the page before and after, in two sandboxed previews, so you can spot what actually changed on screen.

Snapshot before risky changes

One click captures the full state of your folder. Revert to any snapshot to restore everything. Completely stored in your browser.

Desktop, tablet, mobile, fullscreen

Resize the canvas to a phone or tablet, split-view code and preview, or pop the page into a distraction-free fullscreen.

Bring your own model

Claude Opus 4.7, Sonnet 4.6, GPT‑5.5, Gemini 3.1 Pro and the rest of the lineup. Paste your key, pick the model, pay your provider direct.

Long sessions don't fall over

When the chat gets long, MyMonk quietly compacts older turns so you keep working past the model's context window.

A real edit, end-to-end

Nothing changes until you say so.

When the AI wants to modify a file, it stops and shows you exactly what it's about to do. You see the path, the code diff, and — for HTML — a live before/after preview rendered side by side. Snapshot and accept in one click, or reject with a note.

The same is true for creating, deleting, renaming, moving, or copying files. Approval first. Always.

Why MyMonk

Different from the cloud builders.

Most AI website tools live on someone else's servers and own the result. MyMonk runs in your browser, edits your folder, and gets out of the way.

MyMonk Local

  • Your files live on your disk. Open, edit, deploy them anywhere.
  • Plain HTML, CSS, images. No build step, no proprietary format.
  • Approval on every change, with a visual diff for HTML.
  • Snapshot any moment and revert your whole folder in one click.
  • Use whatever model you trust — Anthropic, OpenAI, or Google.
  • Free to leave. The folder is yours.

Cloud site builders

  • Files sit on a vendor's server inside their data model.
  • Custom export, often a paid plan to get usable HTML out.
  • Edits land instantly. Undo varies. Diffs rarely.
  • One AI provider, picked for you, marked up.
  • Migration is the price of leaving.

FAQ

Questions, answered.

How much does MyMonk cost?
$9.99 USD / month, flat. No tiers and no usage caps from us. AI usage is billed separately by whichever provider you use (Anthropic, OpenAI, or Google) — that bill goes straight to them. Cancel any time.
Where do my files actually go?
Nowhere. MyMonk reads and writes the folder you picked, on your disk, through the browser's File System Access API. There's no MyMonk server holding your files.
Which AI providers and models are supported?
Anthropic (Claude Opus 4.7, Sonnet 4.6, Haiku 4.5), OpenAI (GPT‑5.5, GPT‑5.5 Pro, GPT‑5.4 mini), and Google (Gemini 3.1 Pro, Gemini 3 Flash, Gemini 2.5 Flash). You paste your own API key into settings; requests go directly from your browser to the provider you chose. We don't proxy them.
How do snapshots work?
Hit the + button in the snapshots panel — or the Snapshot & accept button on any pending change — and MyMonk captures the full state of your folder. Revert a snapshot and every tracked file is restored, with an optional toggle to delete files added afterwards. Snapshots are stored privately in your browser (OPFS), content-addressed and deduped, so the second snapshot of a mostly-unchanged folder is nearly free.
Can I see what an HTML edit will actually look like before approving it?
Yes. For HTML changes the approval card shows two sandboxed previews — your page as it is now, and as it would be if you accept — alongside the code diff. Assets (CSS, images, fonts) resolve against your folder in both views.
Can the AI see images, and can it make new ones?
Both. Paste, drag, or upload images into the chat — the AI sees them as part of the conversation, and it can also pull images already in your folder into context when you mention them. Supported formats: PNG, JPG, GIF, WebP, AVIF, BMP, ICO. For new visuals, ask the AI to generate one: it'll produce a PNG with OpenAI's gpt-image-1 or Google's Imagen 4 (square, landscape, or portrait), and you approve the result before it's written to your folder.
What if the AI proposes something I don't like?
Reject it, optionally with a one-line reason. The AI receives your note and adjusts its next attempt — and if it's unsure, it'll ask a clarifying question instead of immediately re-proposing the same edit.
What happens on long sessions?
MyMonk auto‑compacts older messages once the conversation gets long, so you can keep editing without hitting the model's context window. Recent turns and the current task stay verbatim; earlier turns get summarized in place.
Does it work offline?
The editor itself runs locally and works offline. Sending a chat message needs an internet connection because that's how the AI provider is reached.
How do I deploy the site I make?
Any way you'd deploy plain HTML — drag the folder onto a static host, push it to a repo, zip it for a client, copy it to a USB drive. There's no build step and nothing MyMonk-specific in the output.
