Where Speak Is Strong
Insight
Speak's goal is to get you speaking out loud from the first lesson, without the pressure of talking to another person.
What Speak offers (checked on its site, October 2026)
- The Speak Method: learn the phrases native speakers use, practise them until they are automatic, then apply them in a back-and-forth conversation with the Speak Tutor AI.
- Real-time feedback on pronunciation and phrasing as you speak, and you can repeat a phrase as many times as you need.
- Speak Premium Plus adds Made for You lessons built from your mistakes, a Speak Tutor lesson creator where you set the topic, and unlimited personalised review.
- A beta "Create your own lessons" feature lets you build custom lessons, with job interview questions given as one example. It is rolling out gradually to some courses.
- Speak for Business offers business-focused conversation courses and role plays for companies, with an admin portal.
- Practice is available whenever you open the app, which makes a daily habit easy.
Interview tip
If speaking English at all still feels stressful, a few weeks of daily AI conversation can lower that barrier before you practise with an interviewer.
Where an AI App Stops for Tech Interviews
A tech interview is a narrow, high-pressure kind of English. You explain a design while someone questions it, tell a STAR story about your own project, and think out loud while you code. General conversation practice helps your fluency, but it does not rehearse those moments.
What Mockly adds
- A human interviewer: the coach plays the interviewer for the full round, with the same structure, timing and pressure as a real loop.
- Tech interview rounds: coding problems (agreed in advance or randomised on the day), system design on a shared Excalidraw whiteboard, behavioural and leadership rounds.
- Feedback on what you said: after the round the coach rewrites weak phrasing, works on ownership language and gives you a drill list.
- Coaches who work in tech: Sophie and Tom are UK-based practising data engineers with 8+ years each teaching English to tech professionals.
- Business English too: sessions can focus on meetings, stakeholder updates and design reviews instead of interviews.
Watch Out
Mockly is not a daily practice app and will not give you unlimited speaking time. Sessions are booked and paid per hour, so many candidates combine them with free daily practice elsewhere.
