Who should pick which

  • Busy professional wanting on-demand speaking practice
    Pick: Praktika

    Praktika requires zero setup, provides instant feedback, and fits into short mobile sessions–ideal for tight schedules.

  • Developer seeking a customizable, privacy-focused tutor
    Pick: Companion

    Companion is open-source, can run locally, and allows full control over the AI and data–perfect for technically inclined users.

  • Budget-conscious learner willing to trade convenience for cost
    Pick: Companion

    No subscription fees; only pay API costs which can be minimal for light use–cheaper than any premium app.

  • Absolute beginner needing structured grammar lessons
    Pick: Praktika

    Praktika includes structured grammar exercises and a native-language interface, making it more beginner-friendly than Companion's free-form conversation.

    Pick: Companion

    Companion uses Google TTS which can offer more natural voices, and ChatGPT can be prompted for accent variation–but both tools rely on AI voices.
