Unspanglish will become a paid service later. We will tell you the price and give you advance notice; you will never be charged without agreeing first.

-
It sees the mistakes, not the chat
Unspanglish is never given your conversations. It receives only the sentence you got wrong and its correction — never the conversation around it. Your connection URL is yours alone, and regenerating it revokes old access instantly. Read the privacy policy .
-
Nothing to keep up with
No streaks, no daily reminders, no deck to review. Save corrections while you chat or practice, and return whenever it suits you.
-
A record that grows with you
Every correction is filed under the rule or word behind it, so the patterns you repeat become obvious.

I am Hector Perez Arenas. I spent five years working in London and passed the Cambridge Proficiency exam, and I still stop to think about in, on and at. I set up Claude and ChatGPT to correct me as I chat, but the correction disappears with the conversation. I built Unspanglish for me so it does not.
