What Praktika Is

- You talk to AI avatar tutors (such as Tama, Raven, Skye and Noah) that remember your context.
- The tutor can explain things in your native language, which helps beginners.
- It builds a personal study plan around your goals, interests and pace.

- You can start a free conversation on any topic, and choose a soft, balanced or strict tone.

A Walkthrough: Practice in Each
Follow Lucía, a backend engineer preparing for a behavioural round and a coding round.
With Praktika. On her lunch break, Lucía opens a free conversation and tells the tutor about a production incident she handled. The tutor corrects “I was responsible of the rollback” to “responsible for” and fixes a few verb tenses. She retells the story three times until it flows. No one is waiting for her and nothing is at stake.
With Mockly. Lucía books a behavioural session with Sophie. Sophie plays the interviewer: “Tell me about a time you made a mistake in production.” Lucía tells the same story, now fluent. Then Sophie asks follow-ups: “What did you change afterwards? How did you tell your manager?” In the feedback part, Sophie points out that the story has no result and no number, that “we” hides what Lucía did herself, and that the opening takes 90 seconds to reach the point. Lucía leaves with a restructured answer and phrases to practise.
How to Make Praktika Useful for a Tech Interview
Good uses of an AI tutor like Praktika ✓ Daily speaking volume without booking anyone ✓ Lowering anxiety about speaking English out loud ✓ Fixing grammar in stories you will tell ✓ Rehearsing your self-introduction many times ✓ Practising at odd hours across time zones How to get more from it
- Use the strict tone. Gentle corrections feel nice but let mistakes slide.
- Talk about your own work: your stack, a recent incident, a project you are proud of.
- Say numbers and technical terms out loud: latencies, percentages, “SQL”, “cache”, “queue”.
- Time yourself. A good answer to “tell me about yourself” takes about 60 to 90 seconds.
- Write down the corrections you get more than once. Those are the ones to fix before the interview.

Some parts of a tech interview depend on technical judgement, not just language:
- Whether your answer holds up. An interviewer cares whether your design or SQL makes sense, not only whether the words sound right. Mockly's coaches work as data engineers and question an answer the way an interviewer would.
- Whether you sound senior. Saying “I decided” instead of “we tried”, or naming a trade-off before you are asked, changes how an interviewer reads your level.
- Whether your answer has a shape. A behavioural answer needs a situation, your action and a result with a number. An AI tutor can correct a sentence; it does not tell you that the story is missing its result.
- Interview pressure. Talking to a person who interrupts you is different from talking to an app that waits for you.
Praktika's site does not describe coding or system design interview practice. That does not make it weaker as a language tutor; it simply is not what it is built for.
Subscription vs Pay-per-Session
How you pay (as of October 2026)
- Praktika: you can try it free, then a subscription. Its homepage puts the cost at about $8 a month.
- Mockly: a free 30-minute trial with a coach on Google Meet. No card and no subscription.
- Mockly: live 60-minute 1:1 sessions are pay-as-you-go. One session is $50; packs of 5 ($237.50), 10 ($450) or 20 ($850) cost less per session. Credits last 12 months and work with either coach.
- Mockly: Premium is the self-study course at $9.99/month, or $59.99/year, with a 7-day free trial. It does not include a coaching session and you do not need it to book one.
A subscription makes sense for something you use every day. Pay-per-session makes sense for something you need a few times, around specific interviews.
Praktika and Mockly: Pros and Cons
Praktika
PROS: cheap; available any time; instant corrections on pronunciation, grammar and word choice; explanations in your native language; adjustable strictness; many languages. CONS: no human interviewer; not built around coding or system design rounds; cannot judge whether your answer is technically sound or well structured.
Mockly
PROS: a human engineer runs real tech interview rounds; feedback on both structure and English; drill list after every session; business English for tech roles too; free 30-minute trial with no card. CONS: booked sessions, not unlimited practice; $50 per hour costs more than an app; two coaches, so fewer slots; needs about B1 English to start.
Verdict
Use Praktika for cheap, daily speaking practice, especially if you are still building basic fluency. Use Mockly when you need someone to run the interview and tell you whether the answer works.
