Extension ideas to get you started

From productivity tools to developer utilities — describe your idea and the AI handles the code.

Productivity tools

Tab managers, to-do lists, focus timers, note-takers, and session savers that keep users on track.

Shopping assistants

Price trackers, coupon finders, deal alerts, and cashback tools that save users money automatically.

Developer utilities

JSON formatters, API testers, color pickers, CSS inspectors, and debugging helpers for dev workflows.

Content tools

Text highlighters, page summarisers, reading mode toggles, and annotation tools for any website.

Social tools

LinkedIn helpers, Twitter/X tools, engagement trackers, and social media productivity boosters.

Custom dashboards

New tab replacements with widgets, quick links, weather, tasks, and personalised at-a-glance info.

From idea to Chrome extension in 3 steps

No prior experience with browser extensions needed. Just describe what you want.

1
Describe your extension

Tell the AI what your extension should do — what it does, which sites it works on, and any specific features. Plain English is fine.

2
AI generates the code

In under 60 seconds, the AI writes your manifest.json, background service worker, popup HTML/CSS, and content scripts — all Manifest v3 compliant.

3
Upload to Chrome

Download the code package, load it locally in Chrome developer mode to test, then submit to the Chrome Web Store to publish for anyone.

Every file your extension needs

The AI generates the full package — nothing missing, nothing broken.

manifest.json

Manifest v3, correct permissions, icons, and metadata configured for Chrome Web Store submission.

Popup HTML/CSS

A clean, functional popup UI that appears when the user clicks the extension icon in the toolbar.

Background service worker

Handles background logic, alarms, and events without draining the browser's battery or memory.

Content scripts

Scripts that run in the context of web pages — reading, modifying, or interacting with page content.

Building extensions the old way is painful

The Chrome extension ecosystem has a steep learning curve. AI removes it entirely.

Chrome extension docs are complex

The official Chrome developer documentation spans hundreds of pages covering APIs, permissions, architecture, and security policies — just to get started.

Manifest v3 broke most tutorials

The forced migration to Manifest v3 invalidated the vast majority of tutorials, Stack Overflow answers, and YouTube guides. Most online examples simply don't work.

Debugging extension errors takes days

Service worker errors, CSP violations, and permission issues are notoriously difficult to diagnose. A single misconfigured field can break the entire extension silently.
