Most professionals don't have an English problem.
They have a speaking problem.
They've studied English for years. They read it, write it, understand it in meetings. But when it's their turn to speak, in a pitch, a negotiation, a casual exchange with a foreign colleague, something blocks. The words don't come. The confidence drops. The opportunity passes.
After 15+ years coaching executives at companies like Apple, LVMH, Accor, TF1, and Deloitte, our Founder Lauren Schwartz identified a pattern that no language app on the market was addressing: fluency in English isn't one skill: it's two.
And missing either one keeps professionals stuck, no matter how much vocabulary they cram.
The 2 Dimensions of Real Fluency
Social English is everything we underestimate but that matters most: small talk, the coffee-machine chit-chat, the elevator conversation, the pre-meeting banter, the airport pickup chat with a client. The "off" moments.
This is where relationships are built, and without relationships, there is no business.
You can be technically excellent, but if you can't engage a conversation, create a connection, or bounce back naturally, you're missing the door that opens everything else. Social English is the entry point to business.
Business English is the opposite end of the spectrum: the moments where you need to be clear, precise, and impactful. A pitch. A board presentation. A negotiation. A high-stakes meeting. No room for approximation. No room for hesitation.
HelloHai is the only app built around both dimensions: because real professional fluency requires mastering both.
How HelloHai Works
1. Daily Social English Training
A voice-first AI coach you talk to every day, without pressure. Casual conversations on real-life topics, what you did this weekend, your opinion on a news story, how your team meeting went, what you're cooking tonight.
The goal isn't to cram grammar rules; it's to build the reflex. To make English the language that comes out automatically when someone says "How was your weekend?" instead of the one you have to translate in your head.
10 minutes a day. No fluff. No artificial gamification. Just real conversation.
2. Business English Simulation Mode
This is where HelloHai becomes radically different from anything else on the market.
Before any high-stakes professional moment, you open the app and simulate the interaction before it happens. A decisive pitch. A negotiation with a key supplier. A board presentation. A difficult 1:1 with a direct report. A keynote. A media interview.
You give the AI context: you describe the situation, the stakes, who you're speaking with, what outcome you want. You can upload supporting documents (slides, briefs, contracts, agendas) directly into the app, and the AI ingests them.
Then your AI coach plays the role of the person you'll actually be facing: the skeptical investor, the tough buyer, the curious journalist, the demanding CEO.
You live the conversation before it exists. You test. You adjust. You refine. You walk into the real meeting having already done it.
It's the difference between rehearsing in your head and actually rehearsing out loud, with a partner who pushes back.
Core Features
Voice-first AI conversations. Natural, flowing voice exchanges, no awkward push-to-talk, no robotic turn-taking. The AI listens, responds, reacts, and adapts the way a real conversation partner would. Conversations feel like calls, not exercises.
Pronunciation analysis: HelloHai analyzes your pronunciation at every turn of the conversation, not just on isolated words.
You see exactly which sounds, syllables, and word stresses need work, with targeted feedback you can act on immediately.
Grammar and word-choice coaching. After every session, you get a clear breakdown of grammar slips, awkward phrasings, and word-choice issues, with native rewrites that show you what a fluent speaker would have said.
The AI detects patterns specific to your native language background and helps you eliminate them over time.
Realistic role-play simulations. Upload documents, describe a scenario, and the AI plays your counterpart with full context. Investor pitches, performance reviews, sales calls, panel interviews, conference Q&As, anything you'd want to rehearse, you can rehearse.
Personalized learner memory. HelloHai builds a narrative profile of you over time, your role, your industry, your goals, your recurring blockers, your wins.
Each session gets sharper and more relevant because the coach actually knows you. It remembers what you worked on last week and builds on it.
Saved expressions and spaced-repetition quizzes.
Every useful phrase, idiom, or piece of vocabulary that comes up in a session can be saved and turned into a spaced-repetition quiz. Learn it once, lock it in for good.
CEFR-aligned progression tracking. Measurable progress from A1 to C2, with clear indicators across speaking, pronunciation, grammar, vocabulary, and fluency. You see exactly where you're improving and where to focus next.
Session summaries and feedback reports: after every conversation, a structured report: what went well, what to work on, key vocabulary, grammar notes, pronunciation focus areas. No guessing about your progress.
Cross-platform access. Native iOS app (coming soon,) and full web app, practice on your phone during commute, on your laptop before a meeting, seamlessly across both.
