Drop in is a Chrome extension that adds custom features, smart workflows, and integrations to web apps without changing the product.
Overview
Drop in is a browser-based product that lets people add custom features, smart workflows, and integrations to web apps through a Chrome extension. The site positions it as a way to “drop in” new UI and automation on top of tools you already use, without requiring source code changes.
Its main purpose is to extend existing web apps with task-specific controls and data connections. The examples shown on the site range from reply buttons and search helpers to workflow panels, which suggests the product is aimed at people who want to adapt browser apps to a specific process or team workflow.
Features
Context-aware workflows
Create behavior based on the current page or selected app so the added feature can respond to what is already on screen.
Service integrations
Connect Drop in to services such as Airtable, Google Sheets, HubSpot, Notion, OpenAI, Personio, Pipedrive, and YouTube for data access and automation.
Example gallery
Browse and reuse example builds for apps like ChatGPT, LinkedIn, YouTube, Slack, Google, Binance, and GitHub to see what is possible.
Feature control and permissions
Turn added features on or off and revoke access per site, so the browser layer stays under user control.
Team sharing
Share features with a team so people can use the same interface improvements and workflow shortcuts.
Use cases
Extend everyday browser apps
Add task-specific controls inside tools like HubSpot, LinkedIn, or ChatGPT so users can work without switching tabs or copying data into another system.
Standardize internal workflows
Build team-specific buttons, panels, and shortcuts that standardize how a group handles a repeated workflow such as replies, lookups, or exports.
Move data between web apps
Connect app screens to external services like Airtable, Google Sheets, or HubSpot to capture, update, or read records from within the browser.
Prototype from examples
Reuse published examples as starting points when you want a similar browser-side feature, such as smart replies, watch-time tracking, or lead capture.
Manage browser permissions
Apply read and write controls carefully when features need access to page data or external APIs, then revoke access per site when you no longer need it.
