Amazingly accurate and genuinely helpful. This extension has saved me so much time. I tried probably 5 other similar extensions, and even tried using locally hosted Ollama and built my own extension to autocomplete text in Chrome. But nothing is as magical as HyperWrite. It's worth the subscription fee.

How autocomplete helps your users

Get the thought down faster.

Help users finish the message they have in mind with fewer keystrokes.

“I still do the thinking; it just puts it to text faster.”

Survey response excerpt

Find the words that fit.

Offer clearer phrasing while the user decides what they want to say.

“It's great to see it offer phrasing that may be exactly what I was going to describe, just put in a way that could be much clearer!”

Survey response excerpt

Make room for more detail.

Reduce the effort of typing the context, examples, and specifics.

“It saves me a lot of time and keystrokes and makes me more willing to write longer Slack messages, so I can provide more detail to colleagues.”

Your message box, with a helpful next word.

Fits into what
you’ve already built.

Add autocomplete to your existing React textarea. Keep your design and controls. The library handles gray suggestions that follow along as users type.

Tab accepts one word. Keep typing to take the message in another direction. Your users stay the authors.

Your backend gets a short-lived browser session from our API. The browser then requests suggestions directly.

From everyday writing to the chatbot message box.

HyperWrite

Built and tested in our own HyperWrite chatbot.

We added autocomplete to the message box and ran an A/B test. In this early snapshot, a higher share of users with autocomplete became paid subscribers.

That’s why we’re opening it to other chatbot teams: so you can test whether making messages easier to write makes a difference in your product.
