Strengths

Where each one is stronger

No tool is best at everything. Here is the honest version.

Where Smooth AI is stronger

  • A phone app

    Smooth AI has iOS and Android apps, so you can also use it in face-to-face meetings. Deeptrue runs on Mac and Windows computers only.

  • More free minutes

    Smooth AI starts you with 150 free minutes, plus 50 for finishing the tutorial. Deeptrue’s free plan has 60.

  • Cheaper for heavy use

    Smooth AI Basic is $14 a month for 1,000 minutes, and Pro is $29 for unlimited use up to 10 hours a day, with 37% off when billed yearly. If you spend many hours a month in English meetings, that is more time for the money.

  • Interpretation in your own voice

    On Voice Pro, Smooth AI says your Korean, Japanese, Chinese or Spanish in English, in your own voice. Deeptrue uses a natural AI voice.

Where Deeptrue is stronger

  • Not only English meetings

    Deeptrue translates between 31 languages in any direction, so Japanese ↔ Chinese, Korean ↔ Japanese or German ↔ Spanish meetings work too, with suggested answers and notes in those languages.

  • Interpreter Mode in the free plan, any direction

    You speak your language and the other side hears theirs, whether that is English, Japanese, Chinese, German or another of the 31 languages. No extra plan needed.

  • Rehearse before it counts

    Practice Mode lets you rehearse a sales call, interview or presentation with an AI partner. The pronunciation guide and shadowing help you say suggested lines out loud.

  • Coaching beyond English

    Line-by-line coaching covers what you say in English, Japanese, Chinese or Korean, so it also helps when you are the one speaking Japanese or Korean.
