Make Perplexity AI Sound Less Robotic
Perplexity AI is great for research and information gathering, but like many AI assistants, it can sound overly formal and robotic. The good news? Perplexity offers Custom Instructions that let you transform its communication style into something more natural and conversational.
Why Perplexity Sounds Robotic
Perplexity's default style tends to be:
- Very formal and structured
- Heavy on citations and source references (which is good, but can interrupt flow)
- Formulaic response patterns
- Overly polite corporate language
- Default numbered lists for everything
While Perplexity's research capabilities are excellent, these patterns can make responses feel stilted and robotic.
The Solution: Custom Instructions
Perplexity's Custom Instructions feature lets you set persistent prompts that shape how it communicates while maintaining its research strengths.
Step 1: Access Custom Instructions
- Go to perplexity.ai
- Click your profile icon (usually top-right)
- Select Settings → Custom Instructions
- Or navigate directly to the settings page
Step 2: Add Your Humanizing Prompt
In the Custom Instructions field, add a prompt like this:
You are a helpful research assistant with a natural, conversational communication style.
Communication guidelines:
- Use contractions (I'll, you're, it's) naturally
- Vary your enthusiasm—not everything needs "fascinating" or "interesting"
- Skip excessive formality—be conversational but accurate
- Use analogies and examples to explain complex ideas
- Acknowledge when something's tricky or nuanced
- Mix paragraphs with occasional lists (don't number everything)
- Show personality while staying helpful and accurate
- Integrate citations naturally—don't let them interrupt the flow
Avoid:
- Formulaic openings like "Certainly!" or "I'd be happy to research that"
- Numbering everything automatically (save lists for when they help)
- Overly corporate language
- Generic sign-offs after every response
- Making citations feel like interruptions
Step 3: Save and Test
- Click Save or Update
- Start a new conversation
- Test with: "Explain [topic] to me simply"
Before and After Examples
Before (Default Perplexity)
You: "Explain how neural networks work" Perplexity: "Certainly! I'd be happy to explain neural networks. Here's a comprehensive overview:- Neural networks are computational models inspired by biological neurons
- They consist of layers of interconnected nodes (neurons)
- Training involves adjusting weights through backpropagation
- Deep learning uses networks with multiple hidden layers
[Sources: Various research papers and articles]
I hope this explanation helps!"
After (With Custom Instructions)
You: "Explain how neural networks work" Perplexity: "So neural networks are basically trying to mimic how our brains process information, but in a simplified way.Think of it like this: imagine you're teaching someone to recognize cats. Instead of giving them a rulebook, you show them thousands of cat pictures and let them figure out the patterns. That's what neural networks do—they learn patterns from examples.
The network has layers. First layer notices basic stuff like edges and shapes. Middle layers recognize patterns (maybe "pointy ears" or "whiskers"). Final layer says "yep, that's a cat."
The training part? That's where it gets interesting. The network starts guessing randomly, but you keep showing examples and tweaking it. It's like adjusting dials on a radio until the signal comes through clearly.

Advanced Customization
Research-Focused but Natural
Since Perplexity excels at research, you can emphasize both:
You're a research assistant who explains things conversationally. When providing
information:
- Use natural language and contractions
- Integrate sources naturally—don't let citations interrupt flow
- Explain complex research findings in accessible terms
- Use analogies to make concepts clear
- Vary your response structure
Be thorough and accurate (that's your strength), but communicate in a way that
doesn't feel like reading a research paper.
Maintaining Research Quality
You can keep Perplexity's research strengths while humanizing the communication:
Maintain your research accuracy and source citation, but communicate findings in
a natural, conversational style. Use contractions. Vary sentence structure.
Make research accessible without dumbing it down.
Pro Tips for Perplexity
1. Balance Research and Naturalness
Perplexity's strength is research. Your custom instructions should enhance communication without sacrificing accuracy. Emphasize "conversational but accurate" or "natural language with thorough research."
2. Handle Citations Naturally
Perplexity will cite sources. Your prompt can guide how:
Integrate citations naturally into your responses. Don't let source references
interrupt the conversational flow. Mention sources when relevant, but keep the
focus on clear explanation.
3. Match Your Use Case
Research for work: Professional but conversational Personal learning: Casual and friendly Quick answers: Direct and conciseAdjust your prompt accordingly.
4. Test Different Styles
Try variations to see what works best:
- More casual: "Explain like you're talking to a friend"
- More professional: "Professional but conversational—like a knowledgeable colleague"
- More direct: "Get to the point quickly, but explain clearly"
Common Mistakes
❌ Too vague: "Sound less robotic" is less effective than specific guidelines ❌ Ignoring research strength: Don't ask Perplexity to stop citing sources—just ask it to integrate them naturally ❌ Overcorrecting: Lists ARE helpful for research findings. The goal is natural structure, not no structure ❌ Not testing: Always test your instructions with a few queries to see if they're workingTroubleshooting
Still sounds formal?- Be more explicit: "Use very casual language" or "Write like you're explaining to a friend"
- Add examples: "Instead of 'fascinating research,' just say what you found"
- Add: "Integrate sources naturally. Don't let citations break up sentences or paragraphs."
- Emphasize: "Keep the conversational flow—citations should enhance, not interrupt"
- Make your guidelines more specific
- Add: "Maintain this conversational tone consistently across all responses"
Comparison with Other AIs
Perplexity's unique strength is research. Your custom instructions should:
- ✅ Enhance communication style
- ✅ Maintain research accuracy
- ✅ Integrate citations naturally
- ✅ Make research accessible
Don't ask it to stop researching—that's its superpower. Just ask it to communicate findings more naturally.
