 ## Maintainers Note
 
-Srcbook is currently not under active development. After overwhelming demand of making it a managed service, we have built and are operating https://getmocha.com for this purpose!
-
-In the future, we might revive Srcbook for its notebook product (over the app builder one, which is better served by Mocha).
+Srcbook is not under active development.
 
 ## Srcbook
 
-Srcbook is a TypeScript-centric app development platform, with 2 main products:
-
-- an AI app builder (also available [hosted online](https://srcbook.com/))
-- a TypeScript notebook
+Srcbook is a TypeScript notebook that runs locally on your machine.
 
 Srcbook is open-source (apache2) and runs locally on your machine. You'll need to bring your own API key for AI usage (we strongly recommend Anthropic with `claude-3-5-sonnet-latest`).
 
 ## Features
 
-### App Builder
-
-- AI app builder for TypeScript
-- Create, edit and run web apps
-- Use AI to generate the boilerplate, modify the code, and fix things
-- Edit the app with a hot-reloading web preview
