FAQ
How does the LinkedIn Bio Optimizer work?
Paste your existing LinkedIn profile text or resume, enter your target role (e.g. 'Senior Product Manager') and industry (e.g. 'SaaS'), pick a tone (leadership, IC, creative, minimal, technical), and choose a CTA (e.g. 'Open to work', 'Let's connect'). The tool composes 10+ headline variants within the 220-character limit and several About variants within the 2,600-character limit, then scores each on keyword density, clarity, and impact so you can pick the best one.
How are the 220-character headline and 2,600-character About limits handled?
Every generated headline is scored against LinkedIn's 220-character limit and every About against the 2,600-character limit. Variants that exceed the limit are auto-trimmed on word boundaries and flagged with a warning. The character meter shows current/limit so you can edit before publishing. Line breaks are counted as one character each, matching LinkedIn's UI.
How is the profile scored?
Each section (headline and About) is scored on three dimensions: keyword density (does it include role + industry keywords recruiters search?), clarity (active voice, concrete numbers, no jargon pile-up), and impact (action verbs, quantified achievements, differentiation). The headline is out of 100 (40 keyword / 30 clarity / 30 impact); the About is out of 100 with the same weighting. The overall profile score is the average of headline + About.
Can I use my own LLM API key for more nuanced optimization?
Yes. The tool builds an optimal prompt (current profile + target role + industry + tone + CTA + character limits) and calls OpenAI or Anthropic with a key you paste — stored only in localStorage on this device. Without a key, the on-device template engine produces solid baseline headlines and About sections fully offline. Nothing is uploaded unless you opt in.
