How to Write ChatGPT Prompts and Improve Answer Quality

Feature Comparison by Free and Paid Plans

Role-Goal-Constraint Prompt Template and Conversation Review Checklist

Copy the template below and fill in the brackets for your use case. Specifying role, goal, input material, output format, and constraints consistently improves answer quality.

[Role] You are a [domain] expert.
[Goal] Achieve [specific task objective].
[Input Material] Refer to the following material: [text/file/data summary]
[Output Format] Organize as [Markdown table/bullet list/JSON/code block].

[Constraints] - Length: [character count/paragraph count]
- Tone: [professional/friendly/concise]
- Prohibited: [speculation/personal info/specific terms]
- Verification Criteria: [cite factual sources/include calculation steps]

Review checklist: verify in order. First, confirm facts match official sources exactly. Second, compare output against the requested format. Third, check for constraint violations. Fourth, verify the answer is complete enough for immediate use without follow-up questions.

5-Step Procedure from Prompt Input to Data Export

1. Open chatgpt.com, confirm login status, and log in with email or Google account if not already logged in.
2. Paste the structured prompt template into the message box and click Send.
3. When the answer appears, confirm the copy button at top right is active, then select and copy the full answer text.
4. Open Settings → Data Controls → Export to download the full conversation history as a JSON file.
5. For work involving sensitive information, select Temporary Chat from the model menu to disable history saving, then repeat steps 1–4.

Answer Review Criteria and Normal Output Checks

Normal state requires all three conditions simultaneously. First, figures, citations, and code execution results in the answer match official documents or reliable primary sources. Second, the requested output format (table, JSON, code block, etc.) renders without syntax errors. Third, zero violations of length, tone, or prohibited-content constraints.

If any condition fails, enter a Step 3 retry prompt to correct. After three retries, refine the prompt template constraints or restructure and summarize input material, then try again.

Once the checklist passes, the top-right copy button activates, and Settings → Data Controls → Export lets you download the conversation history. For organization accounts, check admin console security policies first.

Error Diagnosis Table and Help Center Alternative Paths

If the answer contains hallucinations, the cause may be missing or ambiguous sources in the input material; specify official document URLs or page numbers in the prompt and retry.

If the output format breaks, the cause may be a format specification of only "table" without column names or data types; add Markdown table headers, column count, and data type examples to the prompt.

If constraint violations repeat, the cause may be prohibitions written only as negative statements; replace "do not do X" with positive instructions such as "write only in Y format." If conversation history disappears, the cause may be session end while not logged in; log in and start a new chat, or use temporary chat to protect important conversations.

If the above steps do not resolve the issue, visit the Help Center (help.openai.com), create an account, and request support via on-site chat. For organization accounts, verify data processing policies and model access permissions in the admin console first.

Always enable temporary chat when handling documents containing personal data or company confidential information.

If file analysis is needed on the Free plan, upgrade to Plus or Enterprise. If organizational data policy is strict, confirm the data processing policy in the admin console before proceeding. Deleting browser cookies resets pre-login conversation settings, so use caution.

Without temporary chat, sensitive information may contribute to model training; select Temporary Chat from the model menu for sensitive work. Organization policies may restrict access to specific models; verify account permissions in advance.

Web search is available only on Plus and higher; Free plan has limited access, so switch to a paid plan when latest information is required. For tasks requiring external data, include exact URLs in the prompt.
