Question 1

How does the LinkedIn Bio Optimizer work?

Accepted Answer

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.

Question 2

How are the 220-character headline and 2,600-character About limits handled?

Accepted Answer

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.

Question 3

How is the profile scored?

Accepted Answer

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.

Question 4

Can I use my own LLM API key for more nuanced optimization?

Accepted Answer

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.
