#autocomplete

Autocomplete seems like one of the easiest features to build. You take the user's input, loop through your list of options, and filter anything that starts with the same prefix: const matches = words.filter(w => w.startsWith(prefix)); And that works for small lists of text. But once your dataset gets large, or your completions come from structured text (like user.address.city or $gte), simple loops start to fall short.

Crafting a perfect prompt for AI chatbots is often a challenge - so much so that startups are creating roles for prompt engineers. Consumer-facing AI apps are increasingly adding features like suggestion buttons or autogenerated recommendations to nudge customers to use the chatbot more frequently and show them about what the app can do. Hero, a productivity startup founded by former Meta employees, announced a new autocompletion SDK today that will fill in prompts for you based on context.
