ChatGPT, as of early 2026, functions as a powerful text generation tool; you provide a prompt describing your desired caption, and it uses its advanced language model to create several options tailored to your specifications.
- Prompt Engineering: Current systems include the ability to specify tone (e.g., ‘witty’, ‘professional’, ‘casual’), length, and even include relevant hashtags.
- Image Context: You can now features describe the image directly within the prompt, allowing ChatGPT to create captions that are visually relevant.
- Brand Voice Integration: ChatGPT can be ‘trained’ on examples of your existing brand voice – uploading previous successful captions significantly improves output personalisation.
- A/B Testing Variations: Generate multiple caption options and use Instagram’s analytics to determine which performs best with your audience.
In 2026, Australian businesses need to be mindful of the ACCC’s guidelines regarding truthful advertising. ChatGPT-generated captions should always be fact-checked, especially when referencing promotions or product claims. Furthermore, ensure captions comply with Instagram’s community guidelines and avoid misleading or deceptive practices. Optimising for Australian slang and cultural references can also boost engagement.
