Show HN: Plainspeak, make AI agents write like a human

Make AI agents write like a person, not a bot.

You know the voice. Every reply opens with "Certainly!" or "Let's dive in". Em dashes land in every other line. Plainspeak turns that off. What should be simple stays simple.

Without plainspeak

Let me walk you through a robust, comprehensive solution that leverages cutting-edge technology to seamlessly streamline your workflow.

With plainspeak

Here is a simple way to save time.

What it does #

01

Bans the AI words

delve, leverage, robust, seamless, utilize, moreover, and more.

02

Bans the filler phrases

No "Let's dive in", no "It's important to note", no "I hope this helps".

03

Bans em dashes

Split the sentence with a period or a comma. Or write two sentences.
