What's New in Cloister Ink
1.0.5
August 13, 2026
- Draft, Format and Revise are three settings, not three stages. The pass menu now says it outright, the help page's section on the passes leads with it, and there is a new question in the FAQ about it. There is no order you have to follow and nothing to finish. If you would rather have spell check on from the first word, start in Revise and stay there for the whole document. - Every place that asks for an Anthropic key now opens a walkthrough: where a key comes from, that there is no approval step to wait on, and a place to paste it without being sent anywhere else. - Help and the FAQ now explain Anthropic's newly announced invisible watermark on AI-generated text, and what it means for passages you bring from Ask into your manuscript.
