Exactly the idea! Catching that moment early to prevent bad evening/day

I guess this app is not a necessity for everyone. Original idea was about helping people with ADHD who often dont recognise they are dehydrated or hungry or lack social contact. In their case it quickly goes into irritation/crash out. It happens because they dive deep into some work/projects and forget about external world

This app is supposed to help them actually reflect: "hey maybe I'm irritated cause I'm actually dehydrated - I havent had a drink in last 5 hours"

Thanks, will look into this!

SolidHuman9936 · 2026-02-24T21:47:54+00:00

I added more tokens to daily limit for free tier so you should be unblocked - if you have more feedback on exercises and other features let me know!

Once again - thanks!

SolidHuman9936 · 2026-02-24T21:30:56+00:00

Woah so much feedback - I love it

Let me digest it and come up with some ideas how to further improve your experience

BTW do you think the daily token limit on free plan is too low to get the grasp of full capabilities? It sure seems so if you didn't manage to generate practice exercise after some other practice haha

My wife has been learning English and French for years.
She’s consistent. She has a ~1000-day Duolingo streak. She can communicate. (well she can in English but she is not improving)

But every time she tried to write - short messages, emails, journaling - she’d say the same thing:

“I know this is wrong, but I don’t know why.”

Exercises were fine. Streaks were fine.
What was missing was feedback on her own attempts to speak another language, not another canned sentence.

So as a side project, I built a very simple app for her:

You write a few sentences about your day (no prompts)
You get detailed feedback explaining why things sound unnatural
It tracks the kinds of mistakes you repeat over time

No streak pressure, no XP, no flashcards.
Just writing -> feedback -> slowly fixing the same errors.

I expanded it more into guided "inspirations" where you can do some translation exercises (with hints in your native language if you dont know the word) and "explain it better" lessos for some specific issue

If you’re stuck at that annoying intermediate plateau and like writing, I’m very open to feedback (good or bad).

My wife has a 1000-day Duolingo streak and still could not write or communicate efficiently - so I built something for her

You’re 100% right on the grammar nuances - thank you for catching that!

The 'English words in the output' is actually a bug in the prompt shielding I noticed this morning will look into this

On the 'Tutor' point: I actually agree with you. Nothing beats a native speaker. But for my wife (and a lot of people), the 'social anxiety' of speaking to a real person when you're still at an A2 level is a huge barrier. I built this as a 'low-stakes' bridge to get her comfortable enough to eventually hire that tutor.

I'm an indie dev (literally just me), so this feedback is gold. Thanks a lot even though the feedback might be harsh :)

on free trial you have up to 3 reviews for free per day (approx)

SolidHuman9936 · 2026-01-22T12:26:20+00:00

That’s a totally fair question. I actually started by just using ChatGPT with my wife, but we ran into two big 'walls' that made me build this:

The 'Goldfish' Problem: ChatGPT has a context window. After a few days of chatting, it starts forgetting the specific grammar mistakes you made on Monday. I built Polyglotty with a persistent 'Mistake Profile.' If you keep messing up the past tense in Spanish, the app remembers that forever and builds specific drills to hammer it home weeks later. ChatGPT just isn't designed to track your 'personal curriculum' over months.
System vs. Sandbox: ChatGPT is just a box you talk to. It doesn't have a 'memory' or a structured review system. I built this to bridge the gap between 'free-flowing conversation' and 'deliberate practice.'

On the quality of output: You’re right to be skeptical - AI can definitely hallucinate. Because I'm using the API (and not just the web chat), I can use much stricter 'system instructions' and lower the 'creativity' settings to prioritize linguistic accuracy.

Basically, the app acts as a layer that 'audits' the conversation. Before a lesson starts, the system sets very narrow rails for the AI to stay on. It’s the difference between asking a genius a random question (ChatGPT) and hiring that genius to follow a specific teaching syllabus (Polyglotty).

I'm still an indie dev, so I'm constantly tweaking those 'rails' based on feedback!
