LSTM IME

LSTM IME is a Japanese input method equipped with a three-layer prediction engine: Claude AI, dictionary conversion, and LSTM language model.

■ Three-Color Display of AI Conversion Candidates
━━━━━━━━━━━━━━━━━━━━━━
Three types of predictions are displayed in color on the candidate bar.

🔴 Red: Dictionary Conversion Candidates
High-precision conversion candidates based on a kanji dictionary (over 13,000 words) and MeCab statistical scoring.
Accuracy improves by learning the reading → spelling combinations confirmed by the user.

🟢 Green: Claude AI Next Phrase Prediction
Anthropic's Claude API reads the context and suggests up to 6 phrases that you are likely to input next.
If you input "The weather today is," "It's nice," "It's bad," etc. will be displayed as candidates.
Your own Claude API key is required. Dictionary conversion is available even without a key.

🔵 Blue: LSTM Model Prediction

An LSTM language model trained on a spoken language corpus predicts the next phrase.

It operates within the device, so it works even offline.
