About

PostLint is a writing tool that uses AI to score LinkedIn posts on authenticity and substance. The feedback is direct, sometimes harsh, but always constructive. 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 come from real experience or genuine expertise? Not just recycled takes.
• 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
• Rate limiting: Your IP address is used temporarily to enforce the 3/day free limit. It's held in short-term memory only and is not logged or stored in any database.
• Payments: Bitcoin payments are processed through MoneyDevKit. We don't collect your name, email, or account information. See MoneyDevKit's privacy policy for details on payment processing.

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.
