15 ChatGPT Tips Most People Don’t Know 2026

TL;DR: 15 proven tips to get more out of your AI tools. Each tip includes exactly what to do.

1. Use Custom Instructions

Set your role, preferences, and output style once. Every conversation starts with your context automatically.

2. Upload files for analysis

Drag PDFs, spreadsheets, images, or code files directly into the chat. ChatGPT analyzes them instantly.

3. Create GPTs for repetitive tasks

Build custom GPTs for tasks you do weekly: email templates, report formats, code reviews.

4. Use voice mode for brainstorming

Voice conversations feel more natural for brainstorming. Talk through ideas instead of typing.

5. Chain prompts for complex tasks

Break big tasks into steps. Each response builds on the last for higher quality output.

6. Ask for multiple options

Say ‘Give me 5 versions’ instead of accepting the first output. Pick the best and refine.

7. Use markdown formatting

Tell ChatGPT to format with headers, lists, and tables. Output is cleaner and more scannable.

8. Reference earlier conversations

Say ‘Like we discussed about X’ to build on previous context within a conversation.

9. Ask ChatGPT to critique itself

After generating content, ask: ‘What are the weaknesses of this? How would you improve it?’

10. Use Code Interpreter for data

Upload CSVs or Excel files. Ask for analysis, charts, and insights without writing any code.

11. Set output length explicitly

Say ‘in exactly 200 words’ or ‘in 3 bullet points’ for precise length control.

12. Ask for step-by-step reasoning

Add ‘Think step by step’ to get more accurate, well-reasoned responses.

13. Use it as a writing coach

Paste your writing and ask for specific feedback: clarity, tone, structure, persuasiveness.

14. Generate test data

Need sample data? Ask ChatGPT to generate realistic test datasets in any format.

15. Create learning plans

Ask for a structured 30-day learning plan for any skill. It creates daily tasks and milestones.
