Frequently Asked Questions
What platforms does the bio generator support?
The tool generates bios for Instagram (150 chars), Twitter/X (160 chars), LinkedIn (220 chars), TikTok (80 chars), website About pages (500 chars), dating apps (300 chars), speaker/conference bios (800 chars), and company team pages (400 chars). Each platform gets a style and length optimized for its norms.
Why does the tool generate 3 bios instead of 1?
Bio writing is personal — the "right" one depends on subtle word choices that feel like you. Generating 3 options gives you alternatives to mix and match from, or to pick the one that resonates most without needing to regenerate repeatedly.
How do I write a good Instagram bio?
A strong Instagram bio uses line breaks for visual rhythm, leads with your role or value proposition, includes 1-2 specific personal details that make you memorable (not just "coffee lover"), and ends with a CTA (link in bio, DM for X, etc.). The character limit is 150 — every word counts.
What should I put in the "3 key facts" fields?
Include facts that are specific and distinctive. Instead of "I love travel" try "Visited 40 countries." Instead of "I'm a developer" try "Built apps used by 500k users." Specific numbers and achievements make bios more compelling and memorable.
Can I use the bio generator for LinkedIn?
Yes. For LinkedIn, the tool generates a first-person, achievement-focused summary that fits the platform's professional tone. LinkedIn's About section allows up to 2600 characters but the most impactful summaries are under 300. This tool targets the first 220 characters that appear before "see more."
How do I make the bio sound more like me?
After generating, edit the bio directly in the text field. Swap out phrases that sound generic with your own words. Add an inside reference, a specific project name, or a quirky hobby detail. The AI gives you the structure; you add the authenticity.
