Arc was great, I never understood why they moved to Dia instead of just putting AI features into Arc.
The only reason I can figure out is that they decided the technical foundations were just wrong, which would be surprising because they put an astonishing amount of work into building some very specific technical foundations for Arc.
Now that Chrome has native vertical tabs I'm back on Chrome, but I do miss Arc's tab tidying and organisation.
You’re being very generous to them by assuming it was technical in nature. They pivoted to AI very early and made Dia their only focus despite it being quite obvious that their user base had zero interest in it. They attempted AI in Arc and had a massive backlash, so instead of recognizing that, they just decided to create a new browser and focus solely on that instead of the incredible UI they had built. If they had gone to a subscription model just to continue developing Arc, I would have gladly paid for it. Instead, they are trying to charge $100/mo for a browser with a useless AI implementation. TBC is the perfect case study in ruining a great idea with bad AI implementation.
