With Plus, there are no usage caps on lookups, translation, or AI explanations. Read at your own pace—you never have to count how many times you use them.
To keep the service reliable for everyone, we only limit usage that clearly goes beyond a normal learning scenario:
When a limit kicks in, the feature is never disabled—we simply slow your request rate for a moment, and it recovers automatically soon after. Normal reading and studying—even heavy use—is never affected.
Full-text read-aloud is exclusive to Plus. High-quality voice comes with 120 minutes per month because audio synthesis is more costly; once used up, it automatically switches to the system voice and resets next month.
If you think you've been limited by mistake, write to me: support@sentiaread.com, and I'll handle it personally.
