ChatGPT helps you write.
Thanis helps you know what to revise.
Use ChatGPT to brainstorm, draft, revise, or work through an idea. Use Thanis when you already have a draft and want to know how it holds up, what needs work, and what to tackle first.
At a glance
Brainstorm, draft, revise, ask questions, or work through ideas.

Ask for what you want through the conversation.

ChatGPT can generate or rewrite language for you.
Thanis leaves the draft alone and tells you what deserves attention.
Two different ways to get feedback.
You shape the feedback through the conversation.
Thanis organizes the review for you.
Yes, ChatGPT can review a draft.
The difference is what comes back. ChatGPT gives you feedback through a conversation. Thanis gives you an organized review you can scan: how the draft is doing, why, and what deserves attention first.
You do not have to figure out the perfect review prompt. Choose the kind of writing, give Thanis the draft, and Thanis walks through it with the right review in mind.
