Choose by a task you can actually complete
If your planned habit is reading a short news text, explore Todaii’s reading path and check whether lookup, audio and review are included in your tier. If you want to connect a workplace reply to its grammar and retry after an unexpected answer, try Lingeva’s public work practice first. Neither feature lists nor AI scores show which app will teach you faster.
A five-minute check before paying
- Choose one task: a short article or a workplace conversation.
- Check the explanation language on your device.
- Give an imperfect answer and inspect the correction: does it explain the change?
- Compare speech transcription with actual pronunciation feedback.
- Check tier, renewal period, cancellation conditions and AI allowance at checkout.
This is an editorial selection method, not a timed test of either app. Exact Todaii AI quotas, current renewal prices and device-specific feature access were not independently verified. Check them in the vendor’s purchase flow; no shared unlimited-AI claim is made.
