About AI Training Work

AI training (data labeling / annotation / human feedback) is the human side of machine learning: people create, edit, and evaluate examples so models learn to produce accurate, safe, and useful language.

This role supports conversational AI by supplying natural, culturally accurate Japanese responses and improving model-generated text so chatbots behave more like native speakers.

• Work is usually fully remote and flexible.
• Many projects need language fluency, attention to detail, or domain knowledge rather than formal credentials.

The Role

We are hiring a Creative Writer (Japanese) on a contract, part-time basis to produce and refine dialogue used to train LLM chatbots.

You will generate authentic, culturally relevant responses to prompts and edit AI outputs so they read naturally across dialects and contexts.

• Employment type: Contractor, Part-time.
• Work location: Remote / Worldwide.
• Data type: TEXT; label types: PROMPT_RESPONSE_WRITING_SFT, TEXT_GENERATION, TEXT_SUMMARIZATION.
• Labeling software: OTHER.

• Rate: $20 / hour (PAY_PER_HOUR).
• Minimum: 10 hours/week.
• Preferred: 20+ hours/week when available.

What You’ll Do

Produce original Japanese responses from prompts and improve AI-generated text so it is accurate, fluent, and engaging.

Apply knowledge of regional dialects and cultural nuance to make chatbot interactions feel realistic and relatable.

• Edit and proofread AI outputs for grammar, tone, and cultural appropriateness.
• Adapt style across registers (formal, casual, professional) and dialects as required.

Prior experience performing WRITING tasks on online data-labeling or AI-training platforms (Remotasks, Outlier, Appen, DataAnnotation.tech, etc.) is highly preferred; rating/evaluation experience alone is less relevant.

You should be prepared to state how many years or months you have spent doing writing tasks on data-labeling platforms and to provide a portfolio link or descriptions of your published works if links are unavailable.

A short live test in Japanese is mandatory and will strongly influence your qualification score. Questions will be provided in Japanese and you must respond in Japanese.
