Everything you need to know about our advanced language learning platform
Find answers to all your questions about LangGecko, organized by category
LangGecko is an advanced platform that transforms any text into bilingual MP3s using customizable voices and smart translation. It's designed for passive, screen-free language learning—perfect for walking, commuting, or multitasking.
LangGecko uses interleaved language learning: it switches between your native and target languages in real-time, helping your brain map words and grammar naturally. You absorb meaning in context, not isolation.
No. LangGecko is optimized for passive learning. You can learn while walking, exercising, cooking, or relaxing. You can also export PDF phrase bindings for optional review.
Yes. You can input anything—articles, stories, dialogues, news, or even your own writing. There are no content restrictions.
LangGecko supports over 80 languages and offers multiple voice options per language using state-of-the-art text-to-speech (TTS) models. Precision Mode voices use Azure's premium text-to-speech (TTS).
• Simple Mode: Word-by-word translation; fast and basic • Smart Mode: Context-aware phrase bindings; natural and fluid • Sentence Mode: Full-sentence translations; preserves grammar and structure
Yes. You can: • Adjust playback speed (e.g., 0.85x for better comprehension) • Choose repetition count per phrase (0–10x) • Set pause duration (0.0–5.0s) • Enable Reverse Binding (learn target → source) • Apply speed settings to source, target, or both
LangGecko uses Azure Translator and applies LaBSE (Language-agnostic BERT Sentence Embedding) to measure translation quality. Smart and Sentence modes are context-aware and professionally optimized.
Precision Mode uses professional translation services with enhanced quality control, ideal for technical or academic content. It leverages certified professional translation services for higher accuracy and consumes more quota but delivers superior results.
Yes. You can view SBERT (Sentence-BERT) similarity scores for each language and mode in the Accuracy Table. These scores quantify semantic fidelity between the original and translated texts.
You get: • A bilingual MP3 (audio file) with interleaved or phrase-aligned audio • An optional downloadable PDF (document) with side-by-side phrase bindings
Yes, with the Max Plan, which includes a commercial use license. Lower-tier plans are for personal use only.
Yes. The Starter Plan includes a 7-day free trial with 2 hours of audio generation per month. All payments are processed securely through Paddle, our trusted billing partner.
Annual plans offer a 20% discount and include the same features and audio quotas as monthly plans. All billing is processed securely through Paddle, our trusted payment partner.
• Standard Mode: Uses normal translation pipeline • Precision Mode: Uses certified professional translation services with higher-fidelity translations and consumes quota faster Example: Pro Plan gives 15h/mo (standard) or 10h/mo (precision)
No, your unused hours do not expire. Any unused audio generation hours carry over to the next month, so you never lose what you've paid for.
All payments and billing are processed securely through Paddle, our trusted payment partner. Paddle is used by over 6,000+ software businesses worldwide and handles everything from payment processing to tax compliance and fraud protection. Learn more at https://www.paddle.com/
LangGecko uses SBERT (Sentence-BERT) cosine similarity with LaBSE (Language-agnostic BERT Sentence Embedding) embeddings to measure semantic alignment between original and translated phrases. Scores range from -1 to 1 (closer to 1 = better).
