What’s New

Version 7.0.6

This update fixes a few small bugs. It includes all the great features in iA Writer 7:

How can you tell if a text was written by a person... or by a robot? Sometimes, you can’t. But at other times, something just seems… off. Using ChatGPT, we often don’t even remember ourselves what we borrowed and what we typed.

Artificial intelligence is a great assistant. But if we blindly allow it to replace our own thoughts and words, we become the mouthpiece of a machine. We need to make sure that we know what we say. And that we say what we mean.

The new iA Writer shows you which words you typed, and which you pasted from ChatGPT or from a friend. It highlights the text you craft yourself and it keeps track of contributors, artificial and natural, so that your voice is what comes through on the page.

For over a decade, iA Writer has helped millions of authors find their voice. With iA Writer 7, we’re making sure you keep it.

# Authorship

- Edits made by AI and other artificial tools are dimmed
- Hand-typed text is always shown in full contrast, making it stand out clearly from dimmed, AI-edited text
- Edits made by other humans are underlined
- Paste menu detects conversations copied from ChatGPT, and offers to automatically mark authorship for your questions and ChatGPT’s answers
- Mark As menu makes it easy to mark authorship of selected text
- Paste As menu pastes text and marks authorship at the same time
- Paste Edits From menu automatically detects changes between the selected text and the pasted text, and attributes the changes to the author you choose
- Authorship annotations are saved at the end of files. Hidden when editing in iA Writer, and visible in other apps

色々なテキストファイルを開くことが可能で素晴らしいですし 試しに…と書いてみましたが集中して書けます。

ただアプリの紹介の画像の最後ですがmacOSでも使えるように誤認してしまう可能性を感じます。 実際自分もあわよくばMacでも使えるとむしろこの価格はお得なのでは?と思っていましたが帰宅してApp Storeを開いてみるとMac用はあらためて購入し直す必要があるようです。 よく見ればわかることですが分かりにくいのでご注意ください。

The writing app I’ve been looking for

I just recently switched to iA Writer and it’s exactly what I was hoping it would be. I had been using another markdown-based app for writing and it was good, but missing some features in a way that just persistently annoyed me. iA Writer fixes all of those things and adds a lot of powerful features I didn’t have access to before. It’ll take me a little while to learn how to use all the features of the app, but it’s already my new favorite app to use for writing, and will be great for keeping track of research notes using a Zettelkasten method. Almost never do I bother to write 5-star reviews, because I don’t think most products really deserve a full 5 stars, but this one definitely does.
