OG title & description: Built a Chrome Extension Using AI — From Idea to 500 Installs: Tech Stack, Launch Playbook, and Takeaways.

Keyword strategy

Primary: build chrome extension with AI, AI-built chrome extension case study
Long-tail: how to make a chrome extension fast, using GPT to code extensions, shipping chrome extension weekend, indie hacker chrome extension growth, manifest v3 with AI
LSI: MV3, content scripts, background service worker, permissions, store listing, SEO/ASO for extensions, onboarding, analytics, pricing experiments
Question: can AI code a chrome extension, how to publish to chrome web store, how to grow extension installs, what tech stack for chrome extensions, how to debug manifest v3
Geo: global/English; indie dev focus

User intent analysis

Audience: Indie builders, engineers, no/low-code tinkerers.
Intent: Learn how AI accelerates extension development and early growth, with a concrete playbook.

The Idea and Quick Validation

Pain picked: <replace with your use case>—small, frequent, browser-native.
Validation: landing page + waitlist; shared in 2 niche communities; 50 signups in 48h → greenlight.

Build Stack (Ship Fast, Keep Simple)

AI assist: GPT-style codegen for boilerplate, regexes, and docs lookup.
Tech: Manifest V3, content script + background service worker; minimal UI via popup + options page.
State/storage: chrome.storage.sync for settings; local fallback for bigger payloads.
Bundling: Vite/Rollup/ESBuild for quick HMR during dev.
Testing: Manual + small Jest suite for core logic; chrome.scripting mocks.

Development Flow With AI

Use AI to scaffold manifest, permissions, and messaging between content/popup/background.
Ask AI for code comments on tricky APIs (alarms, storage, tabs) and convert to minimal snippets.
Keep prompts small/specific; paste stack traces for targeted fixes.
Pair AI suggestions with quick sanity checks—console logs and minimal tests.

Key Features Built First

Core action that solves the pain in one click/shortcut.
Preferences screen (options) to toggle behavior; sync to chrome.storage.
Lightweight onboarding tooltip/GIF in popup.
Basic analytics (privacy-respecting): open-source telemetry or opt-in endpoint; no PII.

Launch Playbook (Got to 500 Installs)

Polished store listing: crisp title, 2-line value, 4–6 screenshots, 30–90s Loom demo.
Posted to 3–5 niche communities; asked for feedback, not upvotes.
Replied fast to early users; shipped 3 fixes in first 48h → better ratings.
SEO/ASO: keywords in title/short desc; answered 5 related questions on forums linking to store.
Added referral note in popup footer: “Like it? Rate us.”

Monetization/Retention (Optional)

Keep free for first 500–1k users; later add Pro toggles (rate limits, extra shortcuts, cloud sync).
Track feature usage; prune bloat. Add “what’s new” in popup.

Pitfalls and Fixes

MV3 service worker idle timeouts: use alarms/keepalive pings sparingly; move heavy work to content scripts.
Over-scoped permissions: request minimal; consider host_permissions prompt at runtime.
Review delays: ensure policy compliance, avoid remote code execution, and document data use.

FAQ (Schema-ready Q&A)

Q1. Can AI build a Chrome extension for me?
AI can scaffold code and fix errors, but you must verify permissions, policies, and UX.

Q2. How fast can I launch?
A weekend for MVP if scope is narrow and you reuse templates.

Q3. What are common MV3 pitfalls?
Service worker idle timeouts, overbroad permissions, and missing host permission prompts.

Q4. How did you get 500 installs?
Tight value prop, good listing assets, niche community posts, and rapid fixes.

Q5. How to keep users?
Ship small improvements weekly, add opt-in feedback, and keep permissions lean.

Conclusion (Non-promotional CTA)

Keep scope tiny, let AI handle the scaffolding, and obsess over the listing and first feedback loops. That’s how you ship fast and earn your first 500 installs.
