Build a custom Chrome extension with Manifest V3 for your teamrobert koch
A Chrome extension can put the tool you need right inside the pages you already use. I build custom extensions with Manifest V3, the current Chrome standard.
Ideas
Save data from a page to your CRM, sheet, or database in one click
Add buttons or panels to a web app your team uses every day
Highlight, fill, or check fields on a page
Summarize or draft text with AI using your own API account (Premium)
Internal tools for your team, private or published
What you get
Manifest V3 extension in JavaScript or TypeScript
Clean popup, side panel, or on-page UI
Source code you own
Install steps for your team, or help with Chrome Web Store submission
How it works
Describe what the extension should do, and on which sites
I confirm scope and permissions
I build, you test a working version, then I polish and hand over
Good to know. Chrome Web Store review is done by Google, so I cannot promise approval or timing. I keep permissions as narrow as possible to help review. I do not build extensions that collect user data without consent or break a site's terms.
