Vocabulary Trainer Early alpha

Local-first language learning

Vocabulary you choose.
Practice that adapts.

Turn personal word lists into a focused learning loop across meaning, images, sound, and exact recall. Mistakes return until the word is genuinely usable—not merely familiar.

Not another flashcard pile.

One word becomes a set of independent recall skills.

The learning loop

Recognition is the start.
Reliable recall is the goal.

Each lesson moves from guided recognition to active production. Errors are delayed, reshuffled, and brought back in a different form.

  1. 01

    Meaning → word

    Build the first connection with focused multiple choice.

  2. 02

    Word → image

    Separate visual understanding from translation memory.

  3. 03

    Audio → meaning

    Train recognition from locally stored speech and recordings.

  4. 04

    Strict recall

    Type the target exactly, then automate it under time pressure.

Adaptive repetition

A mistake does not reset the lesson.

The card returns after other tasks, preserving context without letting the learner memorize the previous screen. Difficult cards stay visible across learning and custom practice.

Claude roadmap

From a rough word list to a teachable lesson.

The next product slice uses Claude to turn learner-provided vocabulary into concise context, natural examples, and plausible distractors—while the practice engine and personal learning data remain local.

Planned integration · clearly separated from the working alpha

Early alpha · Windows & web

The core learning workflow is ready to try.

Lesson authoring, three-stage learning, custom practice, offline audio, imports, exports, and local progress are functional. Authoring polish, voice management, and the Claude-assisted workflow are still in active development.
