The gap between what you know and what Appster knows
Every time you ask Appster for help, there's a translation step. You describe your tables, recall column names from memory, try to explain how your references connect.
Details get lost. Column names get misspelled. That formula you're troubleshooting? Appster has never actually seen it.
App-Bridge closes that gap.

A Chrome extension that gives Appster eyes on your app
One click captures your app's full configuration — tables, columns, formulas, validation rules, references, slices, actions, views, and automations. App-Bridge makes it all available to Appster before you type your first question.
Live App Context
Tables, columns, column types, formulas, validation rules, references, slices, actions, views, and automations — all captured in real time with one click.
Works Inside the Editor
Works directly inside the AppSheet Editor. Open your app, click the extension, it will automatically Extract — and App-Bridge does the rest.
Appster Reads. You Don't Describe.
