Can I just use ChatGPT to write my LinkedIn posts?

You can, and many people do. The catch is that ChatGPT starts from a blank prompt and invents content to match it, so the result often reads like generic AI writing unless you are skilled at prompting and editing. Proofd starts from your own voice notes, so the substance is genuinely yours and the post sounds like you rather than like a model.

Is Proofd just a wrapper around ChatGPT?

No. The core difference is the input and the process: Proofd interviews you like a journalist, works from your spoken voice notes, preserves your real phrasing, reviews each post against editorial standards, and attaches a verification code proving the post came from you. That provenance-first workflow is the product, not the underlying text generation.

Which is more authentic — Proofd or ChatGPT?

Authenticity comes down to provenance: are the ideas genuinely yours? ChatGPT can produce polished text, but nothing ties it to your actual experience. Proofd builds every post from your own voice notes and proves it, so the authenticity is verifiable rather than assumed.

Do I need to know how to write prompts to use Proofd?

No. There is no prompt box. Your AI journalist asks you questions and you answer by talking. The skill of prompt engineering is exactly what Proofd removes.

Verdict

ChatGPT is a blank box that will write anything you ask — powerful, flexible, and only as good as your prompt. Because it starts from your instructions rather than your own observations, the output tends to sound like everyone else who typed a similar prompt. Proofd starts from your voice notes: it interviews you, captures how you actually talk, and writes posts that carry your real perspective and a provenance signal. Choose ChatGPT if you want a do-anything tool you drive with prompts. Choose Proofd if you want posts in your own voice with no prompting skill required.
