Voxy vs Open English
How Voxy and Open English compare at a glance
Open English is an online English program for companies in Latin America, pairing an 8-level CEFR curriculum (up to B2 today, not C1 or C2) with drop-in live classes and its 'Jenny' AI, and it teaches English only. It is a good fit for companies that only need English up to upper-intermediate, not the advanced fluency many strategic and critical roles demand.

Proprietary AI conversation practice, AI-powered assessments and personalized AI feedback work alongside adaptive learning paths and best-in-class human teachers, with live classes and fresh content available 24/7, and a Customer Success team runs the program against your business goals. It is the stronger fit for global companies that want high engagement and measurable ROI with a partner that owns the outcomes.
Feature comparison
Voxy vs Open English, side by side
A factual, feature-by-feature look at how the two platforms compare for corporate language training.
| Feature | Voxy | Open English |
|---|---|---|
| Methodology | Skills-based, task-based methodology grounded in 30 years of second-language acquisition research. Learners build job-relevant skills while they learn the language. | A full English school across 8 CEFR levels (up to B2 today), pairing live classes with microlearning study units and practice; general English proficiency rather than role-based skills. |
| AI + human instruction | AI Chat and AI Voice Chat for personalized conversation practice based on the lesson content, with instant feedback that shows learners how to phrase things better, paired with live classes led by best-in-class human teachers. | Live group and 1:1 classes with native teachers, plus its 'Jenny' AI, which assists in the teacher-led hybrid class by correcting exercises and answering questions in the chat, an in-app AI chat, and AI pronunciation practice. |
| AI personalization | Smart Paths, Voxy's pedagogically trained AI, adapts difficulty and activities in real time (checked by expert review), plus personalized AI feedback after every AI Chat and Voice Chat and a personalized daily lesson feed. | A placement test sets a fixed 8-level path; personalization is mostly the study pace your Customer Success sets (moderate, frequent, or accelerated), not adaptive platform content. |
| Custom content | Custom courses built from your own materials, such as SOPs and training videos, turned into branded lessons that build language skills in your real work context. | Preset technical English tracks by field (business, HR, sales, engineering, and more); you cannot add your own materials or build new tracks. |
| Skills beyond language | Role-relevant skills built into the curriculum: communication, project management, AI fluency, and leadership. | Core focus is general English proficiency; job-relevant topics like project management and leadership exist only in an optional technical-English track by area, not built into the required program. |
| Live group classes | Group classes are grouped by proficiency level, so learners only join sessions at their level, with a high volume of classes 24/7 across timezones, in 6 core languages. | Three drop-in group types (grammar, conversation, and an AI-plus-teacher hybrid), new sessions every 30 minutes 24/7 on daily set topics; traditional classes cap at 8 learners, while the AI hybrid does not show its class size, so learners cannot tell how many are in the room. |
| Private lessons & teacher quality | 1:1 classes with certified, professionally trained teachers who average 7 years of experience and come from 50+ countries, not only native speakers, which mirrors the accents and cultures learners deal with at work. Learners choose and keep the same teacher, and teacher quality is non-negotiable. | 1:1 classes with native teachers on preset or open topics, drop-in with no scheduling; a different teacher every session, so learners cannot keep the same one. |
| Content library & updates | 26,000+ lessons built from authentic content curated from premier sources like the Financial Times, Associated Press and Bloomberg, with 3 to 5 new lessons added every day. | Microlearning study units, a daily news-based reading feed, idiomatic-expression drills, BBC and TED video exercises, and a human writing-review service (Writing Center). |
| Languages offered | Up to 18 languages through live classes and tutoring. A full structured program (live classes plus a self-study content catalog) runs in 6 core languages (English, Spanish, Portuguese, Italian, French, German), with custom content built on demand. | English only. Spanish sits on a separate, lighter platform (Open Mundo, not 24/7). |
| Assessment | Voxy Proficiency Assessment (VPA), mapped to CEFR, TOEFL, IELTS, TOEIC and PTE, built into every program. | Placement test, mid- and end-of-level tests (70% to advance), per-level certificates mapped unofficially to CEFR up to B2, and a free Cambridge English Skill Test (CEST) voucher (formerly Linguaskill) at level 8. |
| Reporting & analytics | The Voxy Command Center, a live dashboard for engagement, usage, progress, and VPA assessment data at group and individual level. Admins add or remove learners, set permissions, and export any report to CSV, with numbers refreshing in near real time. | An HR portal with usage, units, and practice data at group and individual level, exportable to Excel or PDF, plus leaderboards and one-click nudge emails to inactive learners. |
| Managed service | Fully managed program for every client, regardless of size. Dedicated Customer Success, pedagogy and engagement teams own results end to end and take the operational load off HR. | A dedicated Customer Success manager from kickoff to final evaluation, who sets study goals per group and sends periodic group and individual reports. |
Methodology
How Voxy and Open English teach
Voxy and Open English approach corporate language training differently, and the difference shows up less in a feature list than in what learners actually practise and what they can do by the end of the program.
Voxy uses a skills-based, task-based methodology grounded in 30 years of second-language acquisition research. Learners build role-relevant skills, from communication to project management to leadership, at the same time as the language, so people grow in their careers and you build a more capable workforce.
Open English: A full English school across 8 CEFR levels (up to B2 today), pairing live classes with microlearning study units and practice; general English proficiency rather than role-based skills.
For L&D teams the practical question is what you want to be able to say at the end of the program. If the goal is a proficiency score, both produce one; if it is employees who can handle the conversations their role demands, what matters is whether the training practised those situations directly.
Live instruction
How live classes and teachers work on each platform
Live instruction is where corporate language platforms differ most concretely, and it is the area buyers most often skip past in evaluation, even though it shapes the day-to-day experience more than any single feature.
Voxy group classes are grouped by proficiency level, so learners only join sessions at their level, and classes run at high volume 24/7 across timezones in six core languages. Open English: Three drop-in group types (grammar, conversation, and an AI-plus-teacher hybrid), new sessions every 30 minutes 24/7 on daily set topics; traditional classes cap at 8 learners, while the AI hybrid does not show its class size, so learners cannot tell how many are in the room.
For 1:1 instruction, Voxy learners work with certified teachers who average seven years of experience and come from 50+ countries, and they choose their teacher and keep the same one across lessons. Open English: 1:1 classes with native teachers on preset or open topics, drop-in with no scheduling; a different teacher every session, so learners cannot keep the same one.
Two questions are worth putting to any vendor: how are group classes composed, since mixing proficiency levels changes the experience for everyone in the room; and does a learner keep the same instructor over time, since continuity decides how much of each session goes to teaching rather than re-establishing context.
AI
What each platform automates with AI
Both Voxy and Open English use AI in the learning experience. The difference is which part of it the AI is pointed at, and how much of its output is checked by people before learners rely on it.
Voxy's AI is proprietary and pedagogically trained. AI Chat and AI Voice Chat give learners conversation practice drawn from the lesson content, with personalized AI feedback after every session, and Smart Paths adapts difficulty and activities in real time. Its output is checked by language-teaching experts rather than trusted blind.
Open English: Live group and 1:1 classes with native teachers, plus its 'Jenny' AI, which assists in the teacher-led hybrid class by correcting exercises and answering questions in the chat, an in-app AI chat, and AI pronunciation practice. A placement test sets a fixed 8-level path; personalization is mostly the study pace your Customer Success sets (moderate, frequent, or accelerated), not adaptive platform content.
The design intent is what matters most. Voxy pairs AI with best-in-class human teachers: the AI creates space to practise and personalize, expert teachers give feedback that sticks, and together they build real confidence at work.
Content
Content that stays current and relevant to the work
Voxy builds its lessons from authentic content curated from premier sources like the Financial Times, Associated Press and Bloomberg, with 3 to 5 new lessons added every day. Open English: Microlearning study units, a daily news-based reading feed, idiomatic-expression drills, BBC and TED video exercises, and a human writing-review service (Writing Center).
What tends to matter more to an L&D team than raw library size is whether the content stays current and whether it reflects the business your employees actually work in, since relevance and freshness are what keep people coming back to the program.
On freshness, Voxy's daily additions mean learners practise with material tied to what is happening now rather than static coursework. On relevance, Voxy matches content to each learner's role and industry, so a finance team and a manufacturing team are not working through the same lessons.
Service & reporting
Who runs the program, and what you can show leadership
Voxy runs a fully managed program for every client, regardless of size. A dedicated Customer Success, pedagogy and engagement team owns results end to end and takes the operational load off your team, and most programs launch in under a month. Open English: A dedicated Customer Success manager from kickoff to final evaluation, who sets study goals per group and sends periodic group and individual reports.
On reporting, Voxy runs through the Voxy Command Center, with live engagement and progress dashboards that include assessment data from the Voxy Proficiency Assessment, and numbers refresh in near real time. Open English provides an HR portal with usage, units, and practice data at group and individual level, exportable to Excel or PDF, plus leaderboards and one-click nudge emails to inactive learners.
Because Voxy's assessment is built into every program rather than sold separately, you get a baseline at enrolment and repeat measurement as learners progress, which is the before-and-after data budget conversations require. On outcomes, 90% of Voxy learners significantly improve their proficiency within three months.
You also get full autonomy in the Command Center to add and remove learners and pull the data you need yourself, and a Voxy team is always there to support you. When you evaluate any vendor, get in writing what level of service is included at your account size, who is accountable for learner engagement, and how quickly reporting data updates.

Case Study · Manufacturing
83% active engagement across a 10,000+ employee, multi-country workforce
Maxion Wheels needed to raise English proficiency across a workforce of 10,000+ employees spread over 24 factories in 12 countries. The L&D team wanted a program people would actually use day to day, with clear visibility into progress and a link to on-the-job performance.
Voxy's Customer Success team built and ran the program, using structured engagement actions to keep participation high across factories and time zones. In the end, the program reached 83% active engagement, 55% of learners moved up 1 to 2 levels, 71% reported productivity gains, and learners progressed 3x faster than with traditional learning.
