Comparison
ShipPost vs RedactAI for LinkedIn posts
RedactAI clones your existing LinkedIn voice. ShipPost generates posts from your development work. Two fundamentally different approaches to the same problem.
The honest take
RedactAI takes an interesting approach: it analyses your past LinkedIn posts to learn your writing style, then generates new posts that match it. If you've been posting on LinkedIn for a while and have a distinctive voice, that's genuinely clever. The model learns your patterns, your sentence structure, your vocabulary — and produces output that sounds like you.
The catch? You need to already be active on LinkedIn for it to work well. If you're a developer who's posted maybe twice in the last year (or never), RedactAI has nothing to learn from. It's solving a problem you don't have yet — voice consistency — when your actual problem is "I have no idea what to post about."
ShipPost approaches it differently. Instead of learning your voice from past posts, it generates posts from your actual work — merged PRs, URLs you want to share. The voice comes from hand-tuned prompts you can edit, not from training on your history. It's designed for developers who are starting from zero or who want their content to reflect what they're actually building.

The scenario
A developer who rarely posts wants to share a recent PR about implementing rate limiting
RedactAI output (limited history)
Implementing rate limiting in our API was an important step. It's crucial to protect your services from abuse. Here are three things I learned from the process. Rate limiting is more than just blocking requests — it's about building resilient systems.
ShipPost output
Shipped rate limiting for our public API yesterday. Went with a
sliding window counter in Redis — 100 requests per minute per
API key, with a 429 response that includes a Retry-After
header.
The implementation was straightforward, but the interesting
decision was where to put the limiter. We considered middleware,
API gateway, and application-level. Went with application-level
because we needed per-endpoint limits, not just per-key.
Total diff: +180 lines, -0. Sometimes new code is the right
answer.

FAQ
Common questions
Does RedactAI work with GitHub? +
No. RedactAI focuses on learning your LinkedIn writing style from your past posts. It doesn't integrate with GitHub, read PRs, or understand code context. If your content strategy revolves around sharing what you're building, ShipPost is the better fit.
Which is cheaper, RedactAI or ShipPost? +
ShipPost is free — you pay only for Anthropic API usage (a few cents per post). RedactAI has a limited free tier and paid plans that start at around $20/month. For occasional posting, ShipPost costs essentially nothing.
Can I use RedactAI if I've never posted on LinkedIn before? +
Technically yes, but you won't get its main benefit. RedactAI's strength is learning your voice from past posts. With no history, it falls back to generic output. ShipPost doesn't need any posting history — it generates from your PRs and URLs.
What AI model does RedactAI use? +
RedactAI uses a proprietary AI system. ShipPost uses Claude by Anthropic with hand-tuned system prompts that you can view and edit directly.
