Asterix

Edit your writing like you edit a photo.

Company we built
We built Asterix in 2021, before ChatGPT, as a writing tool that made AI feel familiar: shorten a passage like cropping a photo, clean it up with auto-adjust, or shift the tone with a filter.
Impact
Asterix explored a more direct way to work with AI, editing the writing itself instead of stopping to prompt a chatbot.

During beta I watched someone drag the crop slider back and forth on a paragraph like they were resizing an image. That's when the photo metaphor stopped being a theory and became the product.

Crop. Makes any text shorter or longer, borrowing an editing gesture everyone already knows.

How it works

Highlight text anywhere on your Mac, or dictate a rough thought, and pull it into Asterix. Crop it shorter or longer, run auto-adjust, or hover through the tone filters and watch your words change live. When it reads right, Asterix pastes the polished version back exactly where it came from.

Auto-Enhance.

Cleans up grammar and flow in one click, since most people just want the fix.

Filter gallery.

Hover across tone filters and watch your text morph instantly, a trick we borrowed from Photoshop's filter gallery so you always see the change before you commit.

Describe your change

Grab text in any app, type a quick change like "make this an apology," and it replaces the original text.
