Hey, cool to meet someone who went down a similar avenue. BubbleRings also looks like a real fun startup.

It used to be a form without typeaheads for years on Gnoosic too.

I never manually fixed typos, but I have put quite some work into making the system figure them out on its own. For example by asking people "Hey, you entered 'The Beatled' which sounds a lot like the popular band 'The Beatles'. Could it be you meant 'The Beatles'?" and then offering buttons for yes/no etc.
