Hello HN!

I’m the developer of WizardFlow. I built this because I noticed users on r/PhotoshopRequest were wasting minutes manually watermarking images in Photoshop and copy-pasting reply templates just to follow subreddit rules.

The Problem: The workflow was fragmented (Edit -> Save -> Watermark -> Upload -> Copy Text -> Reply). The Solution: A Chrome Extension that handles watermarking and templating directly in the browser.

Technical Details:

Privacy First: It uses HTML5 Canvas (OffscreenCanvas) to generate tiled watermarks locally. No images are uploaded to my servers.

Efficiency: It interacts with the Clipboard API to allow a "One-Click Copy" workflow for both the image (Blob) and the markdown text.

Stack: Plain JavaScript (Vanilla), Manifest V3.

It’s currently free. I'd love to hear your feedback on the implementation or features I should add next!
