Side by side
| Praktika | Language Boss | |
|---|---|---|
| How it is built | Conversation with named AI avatar tutors, 1,000+ lessons and a personal study plan. | Koda writes each scene from what you want English for, with a role and missions. A table read comes before it and dailies after it. |
| Who sets the situation | You choose in Free Talk. In Custom Topics you set the topic, your role and the tutor's role. It can also build a lesson from an upload, such as your resume. | Koda, from your dream. You can also pitch a scene and he writes it. |
| Correction while you talk | Tips and subtle corrections after each response, in a soft, balanced or strict tone. | The character folds the fix into its reply, in role, at your level. Explanations come after the call. |
| Your sounds | Tap "?" on one of your messages for an overall and per-word score, based on pronunciation, fluency, completeness and rhythm. It doesn't score each sound. | Every sound of every take is scored after the call, and you hear what it came out as: "the th in think came out as s". |
| Seeing your mouth | No mouth or tongue visuals. The avatars have lip-sync and expressions. | X-ray Mouth replays your selfie with the tongue drawn over your own cheek. Free. |
| What it remembers | Tutors remember your context, on Premium. It adjusts to your level, pace and types of mistakes. | Counts each mistake and sound across all your takes and ranks what to fix first. The next character listens for your top three recurring mistakes. |
| Help in your language | The tutor explains in your language, with a manual toggle. | The scene stays in English and Koda explains in your language. That help fades as your level rises. |

A tutor, or a character in a scene
Praktika gives you a tutor to look at: you talk to an avatar on what looks like a video call, and you can bring your own material. Uploading a resume to practice for an interview is a good idea. If you want a tutor to talk to, or you want other languages, that is what it is for.
In Language Boss the person you talk to isn't teaching you. It is a barista, an interviewer, a landlord, and you have something to get done with them. The teaching happens around the scene: a table read before it, the character's natural corrections during it, and your sounds and lines after it. Koda writes it from what you told him you want English for. Here is what the research says about role-play, including its limits.
Feedback when you ask, or on every sound
In Praktika you tap "?" on one of your messages to see how it scored, word by word, and you can play the tutor's version beside yours and retry. That is handy for checking a sentence you weren't sure about.
In Language Boss, every sound of a live take is scored after the call whether you asked or not, and it adds up across every scene into a ranked list of what to fix first. You find out what you keep getting wrong without having to suspect it first. X-ray Mouth then draws the physical change over your own cheek. No other language app draws it over your own face. Start with the th sound or v and w.
