An AI language app betting that fluency comes from conversation, not flashcards.
Most language apps are quietly good at one thing: making you feel productive without making you fluent. You tap the correct box, keep a streak alive, and then freeze the moment a real person says hello. Praktika.ai was built around that gap.
The London-based startup makes a mobile app where the core activity is not matching words but holding a conversation. Learners speak out loud to AI avatar tutors - characters with names like Raika, Tama, Skye, Camila and Min-Jun - that reply in real voices, carry accents, and even shade their delivery with emotional inflection. The tutor listens, corrects pronunciation and grammar on the fly, and adjusts the lesson to how the learner is actually doing.
The pitch is disarmingly practical. A human tutor might cost around $400 a month, which prices most people out of daily speaking practice. Praktika runs roughly $8 a month. It is not sold as a replacement for human warmth so much as a way to practise every day without booking anyone.
That framing has scaled. The company reports more than 30 million registered learners, 1.2 million monthly active users spread across 100 countries, and a 4.8-star app rating. In May 2024 it raised a $35.5 million Series A led by Blossom Capital, on the back of roughly $20 million in trailing revenue.
Praktika teaches languages the way people actually acquire them - by talking. The app covers speaking, listening, reading, grammar and vocabulary, but the center of gravity is the spoken exchange. Correction intensity is adjustable from soft to balanced to strict, and a free-conversation mode lets learners talk about anything.
Adults and young adults learning to speak - most learning English, with Spanish, French and German expanding. People who want reps, not just theory.
The real barrier isn't vocabulary - it's the fear of sounding wrong in front of a person. An AI tutor never judges, so learners keep talking.
Where rivals gamify vocabulary, Praktika engineers accents and emotional inflection to mimic human-to-human interaction - its stated point of difference.
Praktika's business model is B2C subscription - freemium, with a paid tier that unlocks unlimited tutoring. The value proposition is mostly this comparison:

Praktika's second act follows a first one. The founding trio previously built Cleverbots, a conversational-AI service business whose clients included Coca-Cola, Kimberly-Clark and AstraZeneca. That background - years spent making chatbots hold a coherent, on-brand conversation - is the engine underneath the app.

Part of what makes Praktika interesting is that it doesn't rely on a single large language model. The company orchestrates several - GPT-4, GPT Turbo, Gemini, Claude and Mistral - routing to whichever fits the moment, whether that's holding a natural exchange, correcting a sentence, or remembering a learner's goals.
The other asset is data. Praktika says it holds terabytes of anonymized human-AI interaction data, which feeds back into improving the tutors. Every awkward pause and every "can you say that slower" teaches the system how real learners actually stumble - a flywheel that competitors can't simply download.
The voice layer matters too. One of the company's angel investors is Carles Reina, a co-founder of the voice-AI firm ElevenLabs, and the app's expressive, accented tutor voices reflect that emphasis on sounding human rather than robotic.
It's an approach the CEO sums up bluntly: "We are the only app out there about tone of voice, where you mimic human-to-human interaction."
Language learning is a crowded market, anchored by Duolingo's gamified empire and subscription players like Babbel and Memrise. A newer wave - Speak, Fluently, ELSA - competes closer to Praktika's turf on AI-driven speaking. At the other end sit human-tutor marketplaces like Preply and iTalki, the very services Praktika prices against.
Praktika's position is to be the conversation specialist: not the biggest vocabulary trainer, but the app you open to actually talk. It's a deliberate choice to compete on the thing gamification can't fake - and, the company argues, the thing hardest for rivals to copy.
