Introduction to チャットGPT — purpose and basic functions
チャットGPT is a conversational AI assistant optimized to help Japanese-speaking users perform language, knowledge and productivity tasks. Its core design goals are: (1) understand natural-language requests in Japanese (and other languages), (2) generate clear, context-aware text (answers, drafts, summaries, translations), and (3) assist with practical workflows (coding, research, learning, editing). It is iterative: you give a prompt, it returns a draft or explanation, and you can ask it to revise tone, length, or level of detail. Concrete capabilities (short examples): • Explanation and teaching — e.g. "Explain photosynthesis in plain Japanese and give three study questions." → delivers a short Japanese explanation plus practice questions. • Writing and localization — e.g. "Draft a polite follow-up email in Japanese and provide an English translation." → returns two-tone-appropriate versions and notes on honorific choices. • Code and data help — e.g. "Show a Python snippet to load a CSV and print column summaries." → returns working code, comments, and quick test suggestions. Limitations and practical notes: outputs canIntroduction to チャットGPT contain errors (especially factual or up-to-date facts), so verify critical information (legal, medical, financial). It has no independent access to your local files or the internet unless integrated; treat it as an assistant that speeds composition, ideation, and explanation but that benefits from human review.
Main functions and real-world applications
Conversational understanding & knowledge assistance
Example
User: "Explain reinforcement learning in simple Japanese and give 3 one-sentence analogies." → Output: a concise Japanese explanation plus three analogy sentences tailored to a beginner.
Scenario
A university student preparing for exams asks for: a one-paragraph summary, three mnemonic devices, and two short practice questions. チャットGPT supplies the summary, mnemonics, and practice items, then refines them when the student requests more difficulty.
Writing, editing, translation and localization
Example
User: "Draft a polite business email in Japanese asking for a meeting, then produce a slightly more casual variant and an English translation." → Output: three versions (keigo/formal, casual, English) with notes on tone and phrase choices.
Scenario
A small-business owner needs a product announcement localized for Japanese customers and a short newsletter in English. チャットGPT drafts both, adapts register for each audience, suggests subject lines, and produces A/B variants for testing.
Coding assistance, data analysis & workflow automation
Example
User: "Provide a Python function that reads a CSV, computes mean and median for numeric columns, and handles missing values." → Output: ready-to-use code snippet, brief explanation, and edge-case notes (dtype conversion, NaNs).
Scenario
A developer is optimizing a slow SQL query and supplies the original query. チャットGPT suggests rewritten queries, explains index choices, and provides a plan for measuring performance impact (EXPLAIN examples and test dataset suggestions).
Ideal users and why they benefit
Japanese-speaking learners and everyday users (students, language learners, general public)
Why it fits: accessible explanations in plain Japanese, practice questions, quick translations, and writing support (emails, resumes, essays). Examples: a student who needs summaries and practice quizzes; a language learner who asks for natural-sounding Japanese rewrites and vocabulary explanations. Value: lowers friction for learning and day-to-day communication.
Knowledge workers, creators, and small teams (developers, writers, marketers, teachers, researchers)
Why it fits: rapid drafting, ideation, code snippets, debugging tips, research summaries, lesson-plan generation, and localization. Examples: a marketer prototyping ad copy and A/B variants; a developer getting a code review and test examples; a teacher creating differentiated lesson plans in Japanese. Value: accelerates iteration, reduces routine work, and helps non-specialists produce higher-quality drafts — while still requiring human review for critical decisions.
How to use チャットGPT
Visit aichatonline.org for a free trial without login, also no need for ChatGPT Plus.
Open aichatonline.org to try a no-login, free trial chat experience immediately. This is useful for quick tests or demonstrations; note that features, privacy, and retention depend on that site’s policies.
Prepare prerequisites
Have a modern browser or mobile device and stable internet. Decide your goal (drafting, coding, translating, tutoring). Gather any reference text, example outputs, or constraints (audience, tone, length) to paste into the chat for context.
Use clear, structured prompts
State the role (e.g., “Act as a technical editor”), the task, and the desired format. Example: “Summarize this article in 5 bullet points for a non-technical audience.” Provide sample inputs or expected output when possible to reduce ambiguity.
Iterate and refine outputs
Ask for revisions (shorter/longer, different tone, add citations, explain step-by-step). Break big tasks into chunks, request examples or tests for code, and ask for alternative versions to compare.
Mind limitations, privacy, and troubleshooting
Do not share sensitive personal data. Verify facts and legal/medical advice externally (the model can hallucinate). If answers are off, rephrase or provide moreHow to use チャットGPT context; clear the conversation to reset context if needed.

Five key Q&A about チャットGPT
What is チャットGPT and what can it do?
チ ャットGPT is an AI-powered conversational language model that generates human-like text. Common uses include drafting and editing text, brainstorming ideas, translating languages, tutoring, writing and debugging code, summarizing documents, and creating structured outputs (lists, tables, templates). It excels when given clear goals and examples.
How do I get accurate, useful answers?
Be explicit: provide context, desired format, length, tone, and examples. Ask the model to show its reasoning or list steps for complex tasks. Request sources or ask it to flag uncertain points. Iterate—each clarification improves the next response.
Is チャットGPT free to use and are there paid options?
Availability depends on the platform. Some sites (for example, aichatonline.org) offer free no-login trials; many providers offer free tiers plus paid subscriptions or API billing for higher usage, priority access, or advanced features.
How can I use チャットGPT for coding and debugging?
Provide the language, environment, a minimal reproducible example, expected behavior, and error messages. Ask for a step-by-step fix, tests, or optimized alternatives. Request code comments and explainers so you can learn from the changes.
Is my conversation private and secure?
Privacy depends on the service provider. Avoid sharing sensitive personal, financial, or medical data unless you’ve confirmed data handling policies. Some platforms retain chats for improvement—check the privacy policy or use enterprise/self-hosted options for stricter controls.
