Large language models are trained on billions of words of formal writing, so they default to a stiff, hedged, corporate tone. That register is fine for a legal brief and exhausting for everything else — emails, social posts, customer replies, product copy, internal docs. The fix is not a different model. It is giving the model better instructions about how you want it to sound.
Every page on Act More Human exists to make that easier. Free setup guides walk you through where the system prompt lives in ChatGPT, Claude, Perplexity, Gemini, Grok, and Copilot. Custom prompts let you choose tone, voice, sentence length, and the words and phrases you want the model to avoid. Hands-on services build the same thing for an entire team when the stakes are high enough to standardize.
Nothing here requires coding or a paid plan with the provider. Copy a prompt, paste it into the right settings panel, and you are done in under a minute. Tweak it whenever the model updates or your needs shift.
- Do I need a paid plan to use these prompts?
- No. Every prompt on the site works on the free tier of each provider that exposes custom instructions. Free plans typically include system prompts, custom instructions, or a settings panel where you paste the prompt.
- Will custom prompts make my AI hallucinate less?
- Prompts shape style and tone, not factual accuracy. They will not eliminate hallucinations. They will stop the AI from sounding like a hedging press release while it answers.
- How long does setup take?
- Under a minute. Pick your provider, copy the generated prompt, open the right settings page in your AI tool, paste, and save. The guides include screenshots for each provider.
- Can I customize the prompt for my own voice?
- Yes. Use the wizard to answer a few questions about tone, length, traits to lean into, and words to avoid. The prompt is generated to match. You can also write your own from the template and edit freely.
- What if the AI provider changes its UI?
- We update the screenshots and step-by-step instructions when providers ship UI changes. If something looks off, the contact page is the fastest way to flag it.
