Changelog

Providing Style Examples already helps make sure that you get prose you love from Muse. Based on your feedback, we've added a Style Examples field to the Excellent Prose Mode as well.

The Style Examples field is a powerful (but optional) influence, and it appears in the Prose Mode selector when you choose your preferred Prose Mode or AI model. Paste in examples that show Sudowrite how you want your prose to sound—up to 1,000 words—and Excellent will now take that into consideration as it generates your chapter prose.

A couple of quick notes here:

• Style Examples do not appear in the Prose Mode selector under Write Settings—they’re exclusively available in the Draft tool for longer-form prose generation.

• Since Excellent uses Claude 3.7 Sonnet as a base model, we've made this Style Examples field available to 3.7 Sonnet (under Advanced) as well!

That’s it for Style Examples, but while we’ve got you… Here are a couple of other fixes we’ve shipped that you should know about:

• Rewrite Outline Fix - Clicking Rewrite inside of an Outline’s chapter summary was not properly opening the input field. We fixed that, and you can rewrite those summaries as expected.

• Improved Save Frequency - We’re still making improvements to how frequently Sudowrite saves your work. Now when you click History for various Story Bible sections a fresh snapshot will be taken and stored to your History.

• Error Message Presentation - We improved the styling of error messages that appear in your History section when an AI function fails. They look great now, and we hope you never get to see them.

As of today, all newly-created projects in Sudowrite use Scenes. That means all new projects will get the perks of the updated Draft tool—including access to Muse 1.5—by default.

What does this mean for you?

If you’ve joined Sudowrite since March 5, 2025, nothing changes!

If you used Sudowrite before we introduced Scenes, it’s no longer necessary to choose “Update Now” in every project the first time you want to generate chapter prose. Projects are now created with the updated Draft tool by default, and use Scenes (rather than Beats) as the groundwork for chapter prose.

What about your current projects that use beats?

No problem! Those projects will continue to work exactly as before. However, as we mentioned in our previous update, all Sudowrite projects still using Beats will be automatically converted to use Scenes on July 7th. This update will make sure that everyone on Sudowrite has access to the latest features and improvements.

(Need “one more” project that uses Beats for some reason, before then? Reach out to Sudowrite’s support team at the email address below and we can set you up.)

Setting the Scene for Future Improvements

The vast majority of our community has already made the switch to Scenes. This final transition ensures that everyone—regardless of when they joined Sudowrite—gets access to the same powerful, up-to-date tools (and all of the improvements to come).

As always, if you have any questions or concerns about the transition, our support team is here to help. Drop us a note at hi@sudowrite.com.

We’ve been hard at work on some fresh fixes and updates for you!

Large Document History - It was previously possible for some documents to get too big to be saved in the document’s history section. We made some improvements that mean even the largest documents will now retain their version history.

Scene History Update - We improved the logic around how Sudowrite saves your Scenes. Scenes save more frequently now, and if Sudowrite proposes a Quick Fix that you decide to apply, your original (un-"fixed") Scenes are preserved in your Scenes History.

Outline Menu Fix - The + Add menu in the Outline section of Story Bible was not closing when you clicked outside of it, as it should. We fixed that!!

Continue Prose Toggle - After generating prose, your Draft tool dropdown includes a "Continue where the text in document leaves off" toggle. That toggle was not toggle-able for some people—it was stuck either on or off—but we've fixed it, and restored the choice!

Trial Prose Generation - We fixed a bug that was occasionally preventing users trialing Sudowrite from generating prose from their scenes.

Improved Login Links - Some users were having issues using the login links in our emails. We made a change that will make logging in from those links more reliable for all.

Visualize Max Words - It was possible to use Visualize with too many words, which would cause it to unexpectedly error. We fixed that, and Visualize now tells you when you’ve selected more than 100 words so that you can adjust your selection.

Plugin Variable Update - Plugins that were created before the chapter_scenes and chapter_scenes_extra_instructions variables were added did not have access to those variables. We've fixed the issue and all plugins can now access those variables.

Optimized Search Performance - Using Find and Replace in really large documents could previously cause a browser to hang. We’ve made some performance improvements to the tool that will prevent that from happening.

That’s all for now—thanks as always for bringing these issues to our attention!

Yesterday we launched a new version of Muse that makes it better than ever. It’s smarter, 20% more credit efficient, and writes up to 40% longer.

We love it, and we think that everyone should give it a spin—so for Wednesday June 4th, we’ve made Muse 1.5 totally free to use for Sudowrite subscribers. That means that as long as you have an active Sudowrite account today, you can select Muse in your Write Settings or in the Draft tool to generate prose to your heart’s content. 💖

Wondering how to make the most of this? Just choose Muse! It’s still called Muse in the Prose Mode selector, but you’ll notice that the Base Model now says Muse 1.5 . It works in Write (Auto or Guided) and Draft.

A couple of notes:

• Generating Scenes (or Rewriting Scenes) in the Draft tool is handled by a different model—so that will still use credits! You can use existing Scenes or even write your own if you want to keep the entire Draft experience credits-free.

• The credits estimator in the Draft tool will still show a credits estimate—but zero credits will actually be used when generating prose, as reflected in your Recent Activity. Credits would be used

You can use Muse for free today, Wednesday June 4th, until 12:59 a.m. EDT.

Muse has already been called "the best model I’ve ever seen for creative writing." We just made it even better.

Introducing Muse 1.5, the premier AI model for fiction.

• 40% longer scenes - Muse 1.5 can write much longer, and it does so with more detail than ever.

• Better instruction following - Muse is now much more disciplined, and will stay on track even during lengthy generations.

• 20% more credit-efficient - Longer, more cohesive prose for fewer credits!!

• 2x preferred to Claude 3.7 Sonnet - In blind tests in the Draft tool, Muse 1.5 generations were liked twice as frequently as Claude 3.7 Sonnet.

This update to Muse improves it by almost every metric—quality, consistency, detail, and value. Try it now in the Write button and Draft tool.

P.S. We think everyone will prefer Muse 1.5 by a large margin, but you can still find Muse 1 in the Retired Models section (under Advanced) in your Prose Mode selector!

Anthropic just released their latest, greatest models yet: Claude 4 Sonnet and Claude 4 Opus. We’ve made both available in Sudowrite. The team has done limited testing—the models remain in the Experimental section of the Write & Draft selector—but it seems like there's a lot to be excited about!

🧠 Sharper story logic - Both models tout record-breaking benchmarks on reasoning tests. This should translate to more logical and coherent prose generation that sticks to your Story Bible details.

📖 Manuscript-sized Memory – Both models are capable of reading a full manuscript—or at least, thanks to a large context window, taking full advantage of your chapter continuity settings.

🖋️ Very capable continuations – The team's testing suggests that Sonnet at least is super capable of continuing in your Style—like eerily good. Try it for yourself in Write.

Claude 4 Sonnet and Claude 4 Opus are now available in the Write button, Draft, and Plugins.

And here are a few features and fixes we got out the door this week!

Bulk Delete Characters & Worldbuilding - We’ve added bulk deletion to the Story Bible’s Characters and Worldbuilding sections. Just click on a single Character or Worldbuilding card (specifically the non-text area) to select it. Once it’s purple, hold Shift to select multiple consecutive cards, or hold Command (Mac) or Ctrl (Windows) to select multiple non-consecutive cards. Then just click the three dot ••• menu on any selected card to choose Delete and remove all selected cards at once.

Broken Plugin Fix - Certain plugins weren’t working because their original model was deprecated. We updated the model to a current, working equivalent, and those plugins now work as expected.

Quick Chat Selection - Quick Chat had a bad habit of perusing an entire document rather than focusing on the selected text. We’ve fixed that, and it should now prioritize responding in regards to the selection.

Preserve Paragraph Formatting - Certain Story Bible fields with imported content would lose paragraph breaks upon making edits. We fixed that so that imported formatting is now preserved.

Muse Scene Continuation - We fixed an issue with Muse that was causing it to write one scene at a time (rather than continuing) when used in the Draft tool. It will now write all of your scenes at once as expected.

We just added a new Max words option to the Write button's Length of cards selector.

This setting tells the AI to cut loose and write as much as it can (while still staying on task)—that's typically up to ~2,000 words! It works best with the latest AI models and Prose Modes. Given that the credit use of a Write button click is mostly input context, this option should deliver an even better Write button value than before.

The Max words option is now available in your Write Settings.

P.S. We also just fixed a visibility issue with the three dot ••• menu options in dark themes, like Charcoal and Cauldron. So if you couldn’t easily see where options like Import Worldbuilding lived, now you can.

In response to your feedback, we’ve added the ability to import and export Worldbuilding elements!

Worldbuilding import works just like the Characters import, in that you can either upload a file—your worldbuilding notes, a chapter, or even a full work-in-progress—or paste in some text, and then get help from the AI detecting and importing those elements. If you’d prefer to bring your Worldbuilding elements into your Story Bible exactly as-is (without any help from the AI) you can download and complete a template CSV file that will preserve your structure. Meanwhile, exporting will generate a CSV file with all of your existing Worldbuilding elements as rows and their traits as columns.

In other news, we’ve also made the {{ previous_document_text }} variable available in Advanced Plugin creation. This variable uses a Plugin user’s Chapter Continuity settings, reading back through up to 25 linked previous documents and a maximum number of words as defined by the Plugin creator.

These options are available now—though you may have to refresh Sudowrite to see them!
