Purifai
Cleans up the stray asterisks, curly quotes, and hidden formatting that ChatGPT or Claude leave behind, right before you paste text into Slack, Notion, or an email.

Description
Copy text out of ChatGPT or Claude and paste it into Slack or a Word document, and you'll often get leftover Markdown asterisks, smart quotes, long dashes, or invisible formatting that looks wrong or breaks the target app's own formatting. Purifai is a small Mac utility that sits between copy and paste and strips all of that out automatically, so the text lands clean.
It runs entirely on-device with no cloud transmission — nothing you copy ever leaves your Mac. It removes Markdown leftovers and hidden formatting, converts smart quotes and em dashes to plain punctuation, and integrates with common destinations like Mail, Slack, Notion, Google Docs, Word, Teams, and Notes. There's no account or tracking required, cleanup defaults are configurable, and it can launch at login to run in the background continuously. Pricing is a one-time purchase, though the exact price isn't published on the site.
💬 Our review
The short version: if you paste AI-generated text into other apps multiple times a day and are tired of manually deleting stray asterisks and smart quotes, this is a genuinely small, well-scoped fix for a real annoyance — but it's a narrow utility, not a writing or productivity suite, so don't expect more than what it advertises.
The local-only processing is the strongest selling point here: because it never sends your clipboard to a server, it's safe to use even with sensitive or confidential text, which is not something you can always assume about clipboard-adjacent utilities. Against a manual workaround (paste into a plain-text editor first, then re-copy), Purifai saves the extra step and does it automatically across every app you use. There isn't a well-known direct competitor doing exactly this on Mac, which makes it hard to judge value for money without a published price — worth checking the actual cost against how often you'd realistically use it before buying.
