Once you get it there's no way back. The same way every one of us has a different voice, as a different hand writings that tell much about the writer itself. A font can tell stories by its shapes and forms — It's actually not telling anything, it is simply our subconscious making the mnemonic and cultural connection to give it a meaning.

A font can express the dialects and accents like our voice does. It reflects personality and traits. Custom Fonts, when the identity, values, and mission of the tool is clear, can do it really well.

i.e. for this tool, I'd not have expected a 𝑠𝑒𝑟𝑖𝑓. More a 𝚖𝚘𝚗𝚘𝚜𝚙𝚊𝚌𝚎, but due to the instilled idea that AI will at some stage think, they opted for a more humanistic-sans-serif font. And from there the comparison with the Brand font Akkurat and Inter (both sans-serif).

I found the analysis and process to reach the final design pretty interesting
