It should be possible on MacOS. If I take a region screenshot with Cmd + Shift + 4 (and then click on the thumbnail in the corner), the preview window that opens stays on top no matter what, so the base functionality exists.
I'm a little bit confused by this. You say it supports 100+ languages, but on the landing page some languages are colored in and the rest are greyed out, and the total number doesn't seem to amount to 100+.
Also, presumably the local model doesn't cost you anything per token. So why isn't that one the free tier, with the cloud model being in the paid plan? Wouldn't that help you get a lot more users cost-efficiently?
Lastly, your landing page has a lot of "AI hallmarks". This may or may not be a bad thing, but at least on here I imagine many people are fatigued from this pattern.
I'm all for apps that don't use Electron. What did you use for this?
I'd also wager that hiring generalists with no prior experience in the language actually helped them, because they got to instill their culture and style from the ground up with their new hires. Pre vibe-coding, most of those people would'nt have wanted to just jump in and hack away with zero instruction.
