Fluir, a web app that improves Spanish speaking beyond A2
https://getfluir.app
I hit a plateau with my learning, having used Duolingo + tutor. It was only until I tried to read a book that I felt like I was making real progress. Highlighting words in Kindle, exporting them to Anki, then feeding back my progress to my tutor was fiddly and not a good use of my time. Also practicing my speaking once a day wasn't enough.
So I built an app to help me. This app will: 1. Generate Spanish short stories using Claude pitched to your level, narrated with ElevenLabs 2. Every word/phrase you highlight becomes a flashcard. Flashcards use spaced repetition - words you find difficult come up more often per review 3. Chat with Lucía - a turn based conversation who is prompted with the words/phrases you have saved down
You get a use of all the features before subscribing (1 short story, 1 round of flashcards, 1 minute with Lucía), then it's a 7 day trial.
Would love to get some feedback, especially on the AI conversation, as that's the most challenging part of the app I've found so far.
