MySunday vs Bolt
Bolt is “an AI-powered builder for websites, web apps, and mobile apps” that runs in your browser, with nothing to install.
MySunday lets you point at a paragraph, a cell or a slide in Google Docs, Sheets and Slides, or at your web app, and say what you want. It answers, edits the document once you confirm the steps, or hands the change to the coding agent you already use. They do different jobs, and many people will want both.
Bolt
What Bolt is best at
- Building websites, web apps and (with Expo) mobile apps from a prompt, a Figma design or a GitHub repository.
- Everything in one place: Bolt Cloud adds databases, hosting and domains.
- A choice of agents (Standard and Max), with the model picked for you behind the scenes.
- A Select tool for visual edits in the preview, saved back to your code in a batch.
MySunday
Where MySunday fits
- MySunday works on your own machine, in your everyday Chrome, with the dev server and repository you already run.
- The edits come from your own Claude Code or Codex, and MySunday checks the page against what you pointed at after each change.
- You can point at a reference you have the rights to use, such as your design system or a licensed template, in another tab.
- It is not only for code: in Google Docs, Sheets and Slides, point at a paragraph, a cell or a slide and say what should change. MySunday shows the steps and changes nothing until you confirm them, with no coding agent needed.
Both
Use them together
- Prototype a new app in Bolt, connect it to GitHub, then refine it locally with MySunday and your own agent.
- Bolt can import a GitHub repository too, so a project can move between the two through your repository.

| Compared | Bolt | MySunday |
|---|---|---|
| What it is | AI builder for websites, web apps and mobile apps, in the browser [source] | Point at something and say what you want. In Google Docs, Sheets and Slides, MySunday answers questions about it, or makes the edit once you confirm the steps, with no coding agent. On your web app, the coding agent you already use makes the change. It is not an editor and does not write code itself. |
| Input | Chat prompts; a Select tool for visual edits in the preview [source] | Voice: open microphone by hotkey, wake word or gesture, or a floating icon; pointing at elements in Chrome and at boxes in Mac apps; and typed text |
| Works on your existing codebase | Yes: you can import a GitHub repository as a Bolt project [source] | Yes. It works on your running app on localhost and maps it to the repository on your Mac |
| AI agent and model | Bolt’s Standard and Max agents; Bolt picks the model [source] | On your web app, your own Claude Code or Codex, on your own subscription, does the edits. Questions, and edits in Google Docs, Sheets and Slides, use MySunday’s own AI, with no coding agent |
| Checking the result | Bolt says it “automatically tests, refactors, and iterates” to reduce errors [source] | After every change it recaptures the page (screenshot and DOM), replays interactions you copied from a reference, retries automatically and shows you a verification report |
| Where your code lives | In your Bolt project, with optional GitHub sync [source] | In your repository on your Mac; your agent edits it there |
| Hosting | Built in (Bolt Cloud: hosting, databases, domains) [source] | None. You keep deploying the way you do today |
| Pricing | Free plan with token limits; Pro $25/month; Teams $30 per member/month (billed monthly); custom plans for larger teams [source] | Individual $2/month; Teams $20/month per workspace, unlimited users; both include plan credit. Your Claude Code or Codex runs on its own subscription. Trial (Individual accounts only): a free trial, its length and trial credit as shown on the pricing page when you start |
FAQ
Questions
Can MySunday work on a project I started in Bolt?
Yes. Connect it to GitHub, clone it to your Mac, run it locally and point at it in Chrome.
Both let me select an element and describe a change. What is different?
Bolt edits inside its own project and preview. MySunday works on your running app in your own Chrome, sends the task to your Claude Code or Codex, and checks the result with a verification report.
Does MySunday host my app?
No. It changes code in your repository; you deploy it however you do today.
Try MySunday next to Bolt.
macOS app and Chrome extension. Your documents stay in Google Docs, Sheets and Slides, where MySunday makes the edits you confirm; your code stays in your repository, where your own Claude Code or Codex makes the changes.
