About

PostLint is a fun experiment that uses AI to score LinkedIn posts on authenticity and substance. It's opinionated, sometimes harsh, and not meant to be taken too seriously.

How it works

You paste a post, we run it through our scoring system—a detailed rubric that checks for authenticity, substance, hook quality, readability, and AI-sounding patterns. Claude does the analysis, but the judgment criteria are ours. We don't store your posts or track you.

What we check

• Authenticity — Does this sound like a real person with real experience?
• Hook — Does the opening earn the reader's attention honestly?
• Substance — Is there actual insight, or just vibes?
• Readability — Is it clear and well-structured?
• Human Score — Does it avoid AI-sounding phrases and LinkedIn clichés?

Privacy

• Your posts are sent to Anthropic's Claude API for scoring, then discarded
• Nothing is saved on our servers
• No accounts, no cookies, no analytics
• LocalStorage (browser-only) holds your post temporarily during analysis

Posts are processed through Anthropic's Claude API, which has its own privacy policy. We don't store anything, but Anthropic's terms apply to API requests.
