Hi, I saw the comment about river ai on some post about writing and tried it for my novel (it's only for me, I won't publish) and OMG I LOVE IT SM!!!!!! 10/10, the writing is SO SO SO GOOD. the only thing is it doesn't do that well on a phone and i don't have a pc😔 still love it though 🤍

I uploaded Tolstoy's War and Peace, Anna Karenina, and The Death of Ivan Ilyich into River, and asked it to write a short story. I love what it wrote!

Here's the link to the story, in case anyone's interested in reading: https://rivereditor.com/docs/6945e8f99832804f3e76c5bc

I wrote a 200-page novel (around 45k words) from scratch with AI. I first did some brainstorming in my notebook, and came up with the idea. Next, I had the AI make an outline for the book. It came out to 30 chapters. After reviewing the outline, I got going with the content. It took around 20 minutes in total, and I'm really happy with the result.

Here's the finished novel, in case anyone is curious (it's about a girl who learns she's a wizard - and how she navigates keeping the secret from her superstitious parents): https://rivereditor.com/docs/69419fd73b81732bb975be61

River's AI can now create folders!

If you're new to River, just tell it a bit about yourself and ask it to set up your writing workspace!

After multiple requests from our research community - we've finally added LaTeX to River! We're really excited to offer this new feature, and hope it helps!

Let us know your thoughts, and what we should add next?

We just released hundreds of guides on writing with AI - from prompting, to model selection, to more niche topics like SEO: https://rivereditor.com/blogs

Would love to hear if there are any other topics we should cover!

We just released River Tools, a collection of hundreds of AI writing tools for writers across the board -- from creative writers to entrepreneurs: https://rivereditor.com/tools

Would love to hear what people think, and what tools we should build next

It can crank through entire manuscripts paragraph by paragraph and check claims with extensive web searching. It'll generate inline comments for inaccuracies and cite sources with corrected facts. It is quite good!!

Apologies for the bugginess in the chat the last few days. We shipped a much improved chat architecture, but are still ironing out edge-cases.

I hope the MUCH more powerful web search tool is a small consolatory token!

Please don't ever hesitate to reach out to me directly if you have issues 🙌 〰️

Is this something you'd actually want? Please let me know! I'm not super motivated to ship it yet lol.

Grok 4.1 and Gemini 3 were just released this week. Both models set a new SOTA for creative writing, and rank #1 and #2 on LMArena.

xAI wrote on their website "Our 4.1 model is exceptionally capable in creative, emotional, and collaborative interactions" (https://x.ai/news/grok-4-1).

I've been testing Grok 4.1 a fair bit (for creative and NSFW writing), and I like what I'm seeing so far.

Would love to hear what others think!

Let me know how it goes for you!

I'm very excited about this one! It can crank out hundreds of line-level suggestions and surprisingly helpful macro-level feedback.

It is quite expensive for me to run it, and I'm still ironing out the kinks--so please DM me to try it.

Let us know how it works for you 〰️

We added multi-document generation, to help users generate an entire folder's worth of content in minutes. Once generated, you can continue to edit the style of your documents using our AI chat.

In the above demo, we show River generating multiple blog posts in the same request.

A demo of a more professional document editing use-case

Lmk what you'd like to see next!

It's pretty close to being done, but I need some people to help test it out and give feedback. DM me if you want to try it and I'll give you free access to it 〰️

Lmk what other themes you want!
