Writes Instagram bios under the 150-character hard cap. Pick a persona (entrepreneur, creator, artist, coach, brand, personal, fitness, food/travel), set emoji density (0-5), choose a layout (stacked lines / single line / bulleted), optionally add a city + link-in-bio CTA + branded hashtag. Outputs 3 distinct bios with live char counts. Each variant takes a different angle (credentials-led, outcome-led, personality-led) so you can A/B test which voice resonates.
Instagram's bio field is hard-capped at 150 chars. Anything past it gets cut off. Emojis count as 1-3 chars each depending on Unicode codepoints — our generator counts UTF-16 code units so the displayed count matches what Instagram counts.
Notion AI ($10/user/month) is generic writing — no IG-bio-specific char-cap awareness. Copy.ai ($49+/month) and Jasper ($49-125/user/month) have Instagram bio templates buried inside larger writing tools. SocialBu offers an IG bio generator on its $19+/month plan. Free.ai's tool is purpose-built for IG (cap enforcement, layout variations, persona pills) and totally free.
Yes — Qwen 2.5 7B on our GPUs, ~250 tokens for 3 bios. Free signup gets 10,000 tokens — enough for ~40 bio runs. Premium models (Claude, GPT-5) produce tighter, more memorable copy at higher cost.
Eight personas, each with its own system prompt: Entrepreneur / founder, Creator / influencer, Artist / designer, Coach / educator, Brand / business, Personal page, Fitness / health, Food / travel. The model adjusts vocabulary, emoji choices, and tone per persona.
Set emoji density to 5 and the bio leans heavily on emojis as line-leaders for visual rhythm. We don't recommend pure-emoji bios — Instagram search and accessibility readers struggle with them. The default of 2 produces the highest-engagement bios per 2024 IG study data.
Yes, marginally — eye-tracking studies on Instagram profile pages show the down-arrow or pointing-down emoji on the line above "link in bio" increases link clicks by ~15% on creator profiles. Enabled by default if you toggle the link-in-bio CTA.
No — first run free. Sign up for 10K tokens, generation history, premium models.
Yes — type your description in Portuguese, Japanese, Hindi, Arabic, etc., and the bio comes back in the same language.
Variant A is credentials-led ('10 yrs in fintech | helping 200 founders'). Variant B is outcome-led ('Helping you 2x your runway in 30 days'). Variant C is personality-led ('Coffee snob, runway hacker, dog mom'). Pick whichever matches your audience.
No — system prompt explicitly bans all-caps spam, more than 1 hashtag, URLs in the bio (use the link-in-bio CTA instead), and corny phrases ('changing the world', 'passionate about', 'dream big').
Yes — POST to /v1/chat/ with the IG-bio system prompt (inspect template source). Useful for influencer agencies bulk-generating bios for managed creators. Bearer auth, monthly limits. Docs at /api/.
