### 5/5 — OMG! So awesome!

*2026-07-16*

Not so much a companion as a completely customizable way to learn. It’s a fantastic supplement to any language learning program, and leverages AI in a really useful way. I especially like how I
Can create lessons to focus on a word or concept I’m having trouble with.
