PlugThis converts plain-English ideas into working Chrome extensions
PlugThis
A new tool called PlugThis turns plain-English prompts into working Chrome extensions, backend and all. It matters because two founders shipped real, sellable extensions in under a day, no coding required.

There's a new entrant in the AI app-builder race, and this one is narrow by design. PlugThis doesn't try to be Lovable or Bolt for the whole web. It only builds Chrome extensions, and it leans hard into that specialization: Manifest v3 compliance, content scripts, background service workers, all generated from a plain-English description in under two minutes, according to the company.
The pitch is backed by a couple of concrete stories rather than vague promises. Chetan Giridhar, founder of Indexly, says he started building his research-aggregation extension, Indexly Vault, by hand before switching to PlugThis and getting it running in two or three prompts. He liked it enough to build a second extension, Reddit Responder, right after. Crystal Harrison, CEO of SnapTax, says she built a bank-statement importer and had it tested end-to-end in about ten minutes, work she expected to eat days and, in her words, grey hairs.
What separates this from asking ChatGPT to spit out some JavaScript is the plumbing most people forget about until it breaks. PlugThis, powered by Gemini 3.1 Pro, generates the manifest with correct permissions, wires up content scripts to the right URLs, builds the popup interface, and, if you connect a Supabase account, writes a real backend with logins and databases. Plug in an OpenAI or Gemini key and the extension can summarize, translate, or write on its own. Whatever gets generated is yours outright — download the folder, publish it to the Chrome Web Store for the standard $5 developer fee, sell it, modify it, walk away. No lock-in, no tracking, according to the company.
There are 14 ready-made templates to start from, covering things like page summarizers, price trackers, and meeting transcribers, and the company claims most users have a working extension loaded in Chrome within five minutes of signing up. Chrome extensions are a weirdly specific target for a startup, but that specificity might be the whole advantage: generic AI coding tools can produce extension code when asked, but they tend to stitch it together inconsistently, leaving broken permission scopes and mismatched build paths for someone to debug later.
My take — AI-written commentary, not fact-checked reporting
I'm a sucker for tools that solve one problem instead of pretending to solve every problem, and a Chrome-extension-only builder is exactly that kind of focus. The real test isn't whether it can spit out a popup UI in two minutes — every AI tool can fake that demo — it's whether Chrome's review queue and Manifest v3's permission model stay stable enough that a plain-English prompt keeps working six months from now. My money's on this being genuinely useful for solo builders and genuinely annoying for anyone who needs to debug someone else's generated code at 2am.
