## Overview: Acoustic Listening vs Generative AI Explanations

The explosion of large language models (LLMs) has introduced two distinct philosophies in modern language learning software:

- **Trancy** embeds generative AI into the browser and mobile interface. It focuses on translating web pages, generating AI grammar breakdowns for full sentences, and offering conversational chatbot practice.
- **LingoDew** centers on **listening and review**. It aligns every subtitle word to the moment it is spoken, shows dictionary entries from JMdict and ECDICT on tap, and schedules review with the FSRS spaced repetition algorithm. AI sentence explanations are there when you ask for one.

## Looking for a Focused Trancy Alternative?

AI sentence breakdowns are useful, but they come with trade-offs:
1. **Reading Instead of Listening**: Lengthy AI grammar explanations encourage you to read long paragraphs in your native language rather than training your ears on the audio.
2. **AI Errors**: LLMs can make subtle errors when explaining idiomatic Japanese particle nuances or colloquial English phrasal verbs.
3. **Lack of Spaced Retention**: Highlighting words with AI is exciting, but without a rigorous spaced repetition schedule (like FSRS), saved vocabulary quickly fades from memory.

LingoDew keeps the focus on the rhythm and sounds of natural speech.

## Key Feature Comparison: LingoDew vs Trancy

### 1. Word-Level Acoustic Alignment vs AI Translation

When a native speaker says *"Whaddaya think?"* or *"やっぱりそうか"*, the learning challenge is matching the blurred audio signal to known lexical tokens.

Trancy provides a complete sentence translation and an AI breakdown of the grammar structure.

LingoDew uses **forced audio alignment** to link each token to its exact sound wave:
- Tap the reduced form to hear that exact half-second replayed;
- See readings, furigana, and dictionary forms from JMdict (Japanese) or ECDICT (English);
- Dictionary cards appear right away, with no AI generation in between.

### 2. Spaced Repetition: Native FSRS vs Vocabulary Bookmarks

Bookmarking a word is only the first step. True vocabulary acquisition requires recurring retrieval practice over expanding intervals.

LingoDew features a built-in implementation of **FSRS (Free Spaced Repetition Scheduler)**:
- Cards automatically preserve the original subtitle sentence, translation, and audio jump;
- The algorithm calculates memory stability and retrievability based on your performance;
- Cards naturally progress through Unseen, Queried, Learning, and Mastered states;
- Review cards are cached on your device, so daily reviews work without a connection.

### 3. Media Scope: Focused YouTube Listening vs Web Page Reading

Trancy allows dual-subtitling across web articles, YouTube, and Netflix. If your priority is reading foreign-language news articles or blogs in Chrome with bilingual side-by-side paragraphs, Trancy is well equipped for reading.

LingoDew concentrates purely on **video listening comprehension**. By curating daily YouTube videos across difficulty tiers (JLPT N5–N1, CEFR A1–C2), LingoDew ensures that learners spend their study time on authentic, comprehensible spoken input.

## When Should You Choose Trancy?

Trancy is the better option if:
- You want **AI-generated sentence breakdowns** that explain every grammatical component in detail.
- You frequently read **foreign-language web articles** and need dual-language paragraph translation.
- You enjoy experimenting with AI chatbots for open-ended conversation practice.

## When Is LingoDew the Better Choice?

Choose LingoDew if:
- Your primary goal is training your **listening comprehension** to understand fast, real-world native speech.
- You want **word-level audio timestamps** to instantly isolate tricky pronunciations.
- You prefer **instant, reliable dictionary definitions** without waiting for AI prompts.
- You want a **built-in FSRS spaced repetition system** that brings saved words back before you forget them.

## Frequently asked questions

### How is LingoDew different from Trancy?

Trancy relies heavily on generative AI (LLMs) to explain sentences, translate web articles, and generate grammar breakdowns. LingoDew focuses on acoustic listening comprehension: aligning every word to the moment it is spoken and using published dictionaries (JMdict, ECDICT) with built-in FSRS spaced repetition.

### Does LingoDew use AI to explain grammar like Trancy does?

For whole sentences, yes: LingoDew offers AI sentence explanations, 10 a day free and unlimited with Pro. Word taps do not use AI; they show dictionary entries from JMdict (Japanese) or ECDICT (English) with readings and part of speech. Trancy builds more of its experience around AI, including web article translation and grammar breakdowns.

### Can Trancy translate articles on the web?

Yes. Trancy includes a dual-reading mode for web articles and news sites. LingoDew intentionally specializes in spoken video listening from YouTube, focusing on conversational cadence, pronunciation, and listening comprehension.

### How do their spaced repetition review systems differ?

LingoDew features a full FSRS (Free Spaced Repetition Scheduler) implementation directly inside the app, with sentence replay and four-button grading (Forgot, Hard, Remembered, Easy). Trancy primarily saves sentences and words without an adaptive FSRS scheduling algorithm.
