What it takes to build your own
The question this page answers is what it costs to own the same core functionality yourself, with the source code in your hands afterwards.
The starter prompt
Build a Chrome extension that does this: organize bookmarks from Twitter/X, LinkedIn, Bluesky, Threads. AI assistant + export. It should work on Twitter/X, LinkedIn, Bluesky, Threads.How to build it yourself
- Describe the extension. Paste the starter prompt on this page into PlugThis. It generates a working Manifest V3 Chrome extension from that description.
- Connect your own keys. If the extension needs a model or a database, connect your own OpenAI, Gemini or Supabase credentials so usage is metered to you rather than to a vendor's monthly cap.
- Iterate in plain English. Ask for changes the way you would describe them to a person. Builds that error do not count against your allowance.
- Install and own it. Download the folder, load it unpacked in Chrome, or publish it to the Chrome Web Store under your own developer account. The source is yours.

Frequently asked questions
Is Dewey still available?
No. The Dewey lifetime deal on GrabLTD is sold out and cannot be bought at any price, verified 2 August 2026. The product itself may still operate on its own pricing.
How much did Dewey cost?

Organize bookmarks from Twitter/X, LinkedIn, Bluesky, Threads. AI assistant + export.
What is a good Dewey alternative?
You can build an equivalent Chrome extension and own the source code instead of licensing it. PlugThis generates a working Manifest V3 extension from a plain English description. The starter prompt on this page is the exact text to begin with. Our estimate for this one is ~1,000.
Has PlugThis rebuilt Dewey?
Not yet. This page is a record of the deal and a specification for building an equivalent. When we rebuild it on camera, the recording and our measured build time will be added here.
What happens to a lifetime deal after it sells out?
Existing buyers keep their licence, but nobody new can buy at any price, and buyers hold no source code and no leverage over the roadmap. If the vendor changes direction the licence ends with it. Building an equivalent avoids that dependency because the code sits in your own repository.
