Insight Update: September 29, 2026

We have plenty of new tools and features to try in this release! Here’s what’s new in Insight:


Translation: Even Better Than Before

We have refined translations in Insight to read even more naturally and to keep terms and names consistent across the full book.

Insight first reads the book and builds a list of terms, character names, and other elements, which it uses to maintain consistency across the translation.

Insight also follows updated guidelines for more natural-sounding idioms, cultural references, and correct punctuation.

Try it: Open a document and go to Actions > Document Tools > Translate.


Proofreading: Generate a Ruleset from Your Style Guide

The Generate a ruleset with AI dialog, showing the Paste a style guide and Upload a document options

You can now upload your own style guide document into the proofreading tool. Insight will convert your document into a custom proofreading ruleset for you.

Visual Search in Chat: Find Images Inside Your Documents

AI Chat answering a request for social media images from a travel guide, with the Document Vision skill activated and a gallery of pages from the book

AI Chat can now look at the pages and images in a document, not just read its text. Ask it to find images in a book or a document, and it shows you a gallery of images it found.

When you find an image you want to use, AI Chat can crop it, add a headline, or turn it into a new graphic. Your original document is never changed.

Try it: Open a document in AI Chat and ask, for example:


Better Images with GPT Image 2.5 Sunburst

We’ve added OpenAI’s new image model, GPT Image 2.5 Sunburst, to Insight. In AI Chat, this model lets you make more precise image edits, and you can also ask for transparent backgrounds.

In the Create Artwork tool, Nano Banana (Google) remains the default. You can switch to GPT Image 2.5 in the Advanced Options section of the tool.

Try it: Open a document and go to Actions > Image Tools > Create Artwork, or enter an image prompt in AI Chat.


AI Chat: GPT 6 and Claude Sonnet 5.5

GPT 6 is now our default model in AI Chat, and Insight uses this model for more backend processes as well. We’ve also upgraded Claude in AI Chat to Anthropic’s new model, Claude Sonnet 5.5.

Try it: In AI Chat, choose GPT 6 or Claude from the model selector.

Audio: Narration Styles and Languages

The Generate Audiobook dialog with Narration Style set to Literary, Language and accent set to French (Canada), and editable sample text

We’ve added new options to our audiobook tool. Choose a Narration Style and set the Language and accent, such as English (UK) or French (Canada).

Listen to a sample: You can listen to and edit the sample text, or choose a passage from the book itself. If you need a longer sample, try Actions > Audio Tools > Generate Sample.

Try it: Open a document and go to Actions > Audio Tools > Generate Audiobook.
