I have been gifted three days worth of DuoLingo Max, which is the AI powered version of DuoLingo.
It’s a great addition. It unlocks features like video chat, where I can chat with an avatar in Spanish, both verbally and written. It is certainly a step up from what they already have.
However, this benefit comes at a cost, and right now, the additional price isn’t worth it. If it comes down, maybe, but regular Duo is enough for me at the moment.
