Faster Chat, Better Rewrite & Printing

We’ve made some big updates to Chat very recently, improving both its speed and performance.

Chat responses are now twice as fast - We moved Chat to faster infrastructure this week, cutting response time in half in the process. You should definitely notice it on bigger tasks.

Chat makes fewer mistakes - We've been working hard to improve Chat’s performance where it’s most likely to stumble. Our most recent fixes have reduced error rates by 30%, meaning it’s now far less likely to drop context, misplace an edit, or give up. We’re not done yet, though, and there are more Chat improvements to come.

Rewrite now runs on our in-house model - Rewrite had been using Anthropic’s Claude Sonnet for a while. We just moved it to Ballad, and the results speak for themselves: authors are now 20% more likely to actually use the resulting Rewrite. If you haven’t tried Rewrite in a while, it’s worth another spin.

Actually print your documents - Hitting Ctrl + P or Command + P while viewing the Sudowrite editor used to pop up a blank page and a message about needing a wider browser. Well, good news, folks: it will now print a clean version of whatever document you're viewing.

Improved Draft Estimates, Plus a Bunch of Fixes

The team has been hard at work on fixes and key improvements this week. Here’s what’s new.

Draft won’t charge you more than its estimate - We improved the Draft tool’s estimates recently, and in doing so made that estimated range into a promise. You’ll no longer see credit charges in excess of the estimate’s ceiling in the Draft planning step. Hooray!

One note: While making this update earlier this week, we briefly broke the retired My Voice model options in Draft. My Voice users hit a credit-estimation error and couldn’t generate. The issue lasted about a day, but it’s fully fixed now. Sorry about that!

Chat Improvements

Chat reads and inserts more reliably - We fixed a batch of issues that made it difficult for Chat to read your document or insert its edits. Reading and inserting are more reliable now.

Failed plans shouldn’t use your credits - It was possible for a complex multi-step plan like a complete manuscript review to fail and still charge you credits. We fixed that, and you won’t be charged in those cases.

Reduced internal jargon in your messages - Chat’s own reasoning sometimes includes noisy jargon—document IDs, “tool” references, etc. We tweaked it so it would stop referencing that in conversation.

Other Improvements & Fixes

Write now completes the sentence - The Write button previously prioritized your word count preference over completeness of thought—meaning it could stop mid-sentence. It now runs to the nearest complete sentence, even if that means a few extra words.

Custom Rewrite instructions stick around - The Rewrite button’s “Customize” instructions had quietly become single-use. We made it work like it used to, so they stay put for repeated rewrites.

The highlight toolbar waits to appear - When you select text, the pop-up toolbar now appears after you release the mouse button instead of mid-drag—so it stops obscuring the lines around your selection.

Find and Replace now handles doc switching - We changed Find and Replace so that if you have a term entered when switching documents, it re-runs automatically in the new doc.

New titles stay put - Typing a title too quickly in a brand-new project could sometimes snap the title back to “Untitled.” Your title now sticks.

A cleaner document list - We improved the document list in your left bar—giving a bit more space, improving contrast for accessibility purposes, and making (•••) menus and toggles only show up when you need them.

Undo no longer undoes more than it should - We fixed a bug with undo where it could reverse the past few edits rather than just your most recent edit. Meanwhile, the editor’s Undo button now works on the first click after you insert text from a card. (Did you know there’s an Undo button in the editor toolbar? I didn’t, and I write these!)

It’s also worth calling out a noteworthy fix on the Sudowrite mobile app this week:

We fixed the cursor jump in Story Bible - On mobile, the cursor was jumping to the end of certain Story Bible fields after each character, making them frustratingly difficult to edit. We fixed that!

ImprovementFix

Cheaper GPT-5.6 Models, Plus a Batch of Chat Fixes

Some fresh improvements to report: a nice price drop on a couple of our OpenAI models, and another round of Chat improvements based on your feedback.

💸 GPT‑5.6 models just got cheaper

OpenAI recently lowered its prices on some of its models, and we're passing the savings on to you. GPT‑5.6 Luna now uses 70% fewer credits on Sudowrite, while GPT‑5.6 Terra uses 10% fewer. We tweaked GPT‑5.5 while we were at it, and it now uses about 12% fewer credits. You don’t have to change anything to benefit from this—if you write with any of these AI models in Write, Draft, or Plugins, your credits will just go further now.

💬 Chat fixes & improvements

We remain hard at work, making Chat behave the way you expect:

  • See Chat's thought process in Chat Only — The “working” box now shows up in Chat Only mode, just like in Allow Edits.

  • Narrow questions stay narrow — Asking about one specific thing no longer kicks off a full Feedback sweep across every review type, so you won't burn credits you didn't mean to spend.

  • Resend actually resends — If a response stalled, hitting Resend could sometimes throw an error instead of retrying. It now consistently retries.

  • More accurate document edits — We made it so when Chat inserts changes into your manuscript, it places them more precisely.

  • Fewer false "stuck in a loop" messages — Chat would occasionally claim it was stuck in a loop even after finishing the task. We've cut those way down.

  • Story Bible shortcuts in your current chat — Hitting a generate button in Story Bible no longer creates a brand-new chat thread. We made it so the prompt box now pops into your current chat.

🛠️ Other improvements & fixes

  • Generate Scenes costs less on long projects — We’ve optimized the Generate Scenes feature. It now pulls less redundant context, which reduces the cost of scene generation on longer projects.

  • Clearer Draft limit warning — We reworded the Draft input‑limit warning—occasionally triggered in super large projects—so it's less alarming and easier to address.

  • Resizable comment column — We changed the comment column so that it’s fully resizable. Just drag it to your preferred width and it’ll stay that way.

Keep the feedback coming folks! 🫡
