## About Humanize AI Writer

Humanize AI Writer is a web app for editing AI-generated drafts so they read more naturally. You paste text from a tool such as ChatGPT, Claude or Gemini, then run it through the providers the app supports: GPT Human, Undetectable AI, StealthWriter and Ryne AI. Each provider returns its own rewrite, so you can compare the outputs side by side with your original and choose the version that fits your voice.

The site stresses checking the result before using it. Its guidance covers reviewing facts, names, numbers, quotes and citations, and checking that an email still has a clear request or that an article keeps its structure and examples. Results are saved to a private history, and you can copy or download the versions you keep. Paid plans set a monthly word allowance, and the site notes that each provider output uses the submitted word count from that balance.

The product is aimed at people who write everyday content with AI help, including bloggers, people writing client emails, sellers writing product descriptions and anyone posting short social updates. It does not guarantee any AI detector score.

## About NotesIQ

NotesIQ is a Chrome extension for Substack writers who want to understand how their Substack Notes perform. It reads your Notes through your existing Substack session and shows them in a dashboard ranked by engagement, with likes, restacks, comments and content type tracked for each Note. A Viral Alert flags a Note that takes off compared with your own baseline, and the tool keeps a longer history than Substack's own dashboard, which the site says shows only the last 90 days.

The extension also helps with timing and posting. A 7-day by 6-time-slot Best Time heatmap is built from your own posting history, alongside your current posting streak. You can compose a single Note or load a week of Notes into a queue, and NotesIQ uses Substack's own scheduler to publish them at the times you set. A Media Kit feature turns your subscriber count, top Notes and engagement into a one-page sponsor summary that can be exported from the panel.

NotesIQ is aimed at Substack creators who post Notes regularly and want to decide what to write and when based on their own numbers. The site says your Notes, profile and subscriber stats stay in your browser's storage, with no NotesIQ server receiving them, and that the product is a one-time $4.99 lifetime purchase with no subscription.
