Show HN: Revise – An AI Editor for Documents (revise.io)
35 points by artursapek 6 hours ago
I started building this 10 months ago, largely using agentic coding tools. I've stayed very involved in the code base and architecture, and have never moved faster in my life as a dev.
The word processor engine and rendering layer are all built from scratch - the only 3rd party library I used was the excellent Y.js for the CRDT stack.
Would love some feedback!

This looks really nice! Congratulations on building something awesome, especially in a space that's "crowded" with the big players.
I want to give kudos to two things:
1. It took you 10 months to build this. This is focused product development and craftsmanship which is very different from Vibe coding something. So let this be a reminder to all the "I can vibe code this or that in a weekend". Good products / experiences take time.
2. You've pursued building something in a space that anyone would normally dismiss right away: "Why would anyone use this? Google Docs/ Word etc already does this" or "MSFT / GOOG will destroy you". Good on you for picking something that is hard and building it well. I actually had this idea and almost built it but dismissed it myself for the same reasons as above. So reminder again for the builders in the back: Doesn't matter if there is a 800lb gorilla building this, if you can execute it better go for it.
Kudos!

Thanks, that's nice. Yeah it's been 10 months, and 7 of them completely full time... living off savings. I think there's plenty of room for innovation with word processors now that we have LLMs and the big players are unlikely to go far outside the box.

Subsciption and Online means not for me

I'm building a similar project, and I may open-source it. I'm using OnlyOffice and a coding agent that modifies the files with Python libraries in a sandbox (e.g. python-pptx for PowerPoint files).
Have you also considered using a solution like OnlyOffice for your product? Or a "Notion-like" lib such as Tiptap or PlateJS?
artursapek 23 minutes ago
I definitely looked at TipTap and ended up building off their Y.js backend, which is great: https://tiptap.dev/docs/hocuspocus/getting-started/overview
I wanted to build something canvas-based, so that eliminated most of these options. I also just wanted full control of that part of my stack... it's the core product after all. There are several TipTap/ProseMirror wrappers out there already.
You should share yours though, would be interested to see

Thanks for the feedback. It seems my post got flag-bombed at some point. I can't reply to takahitoyoneda anvevoice techpulse_x or Remi_Etien. feel free to email me [email protected]

Er, is right click disabled on this page? Certainly seems to be in any browser I pick. If so, why?

Anecdote from a frustrated typer. There are no good word processors. MS office and Libre/open-whatever-they-call-it-now-office are bloated mess. I did a deep dive on this a few months ago, and there are 0 light/good options. There are a few that show up in google searches, but they are all disappointing in one way or another.
So, thoughts on a non-AI lightweight word processor.

I am not a defender of Word (2024) but it starts in 1-2 seconds in my laptop.
Actually the speed is a problem when you have hundreds of pages with track changes and comments.
Maybe you should check Wordperfect or WordStar ;)

What features would you expect from a good word processor? What features should it leave out, i.e. features make MS Office / OpenOffice / LibreOffice a bloated mess?
the__alchemist 4 hours ago
Start fast (maybe <100ms), respond instantly, good UX.

Ty. I looked at that, and unfortunately cannot recall why I rejected it.

What exactly would the perfect tool look like?
the__alchemist 4 hours ago
Perfect isn't the goal. But something on the tier of KiCad, Blender, Zed, Sublime, etc.

Revise is that, actually. It's a free, lightweight, fast word processor at its core. It also has real-time collaboration, also free. You don't need to use the AI features.
It even supports code blocks, LaTeX, and Mermaid diagrams.
Also, the passive spelling/grammar checking in the editor is powered by LLMs and completely free. It will catch mistakes that other word processors won't, such as malapropisms.
the__alchemist 4 hours ago
Ty; will check it out. That wasn't one of the one I looked at.
Edit: Ah I see, from the OP. Unfortunately, I think Subscription-based, web-app, and vibe-coded would individually be deal breakers. Combined indicates it's not the sort of tool I seek.

How do you make sure the LLM catches and reports all grammar mistakes if I ask for it?
artursapek 4 hours ago
I've built an agent loop that has a self-review step, and it's pretty good at catching mistakes. It's able to scan the document in chunks and use tools to surgically change small parts.

This looks wonderful!
I do a decent amount of writing on my blog and for work so I was thinking, "why doesn't this product appeal to me?"
I think I'm hesitant to spent yet another monthly subscription on something. I get decent mileage just copying and pasting sections into Claude so it's hard to justify another $8 a month on another tool.
I also do a decent amount of my editing in raw markdown files and apply styling almost as a post-process. Part of the problem is that I'm always pasting documents into corporate portals (Confluence, Wiki's, Google Docs) and they don't always copy formatting in the way I'd expect. So I just write raw text and format it after paste.

Thanks for the feedback. The pitch with Revise is it's a fully integrated agent inside a word processor. The "copy and paste between ChatGPT and docs" is the workflow I set out to improve on a la PG's "find something people are doing and figure out a way to do it that doesn't suck." I think you'd find it's a much better user experience, especially when you're iterating a lot on something.
I get that subscriptions turn some people off, and I'm open to other ideas of how to make a project like this financially sustainable. I don't want to do ads :)

Can this be integrated inside of something like Google Docs or Microsoft Word? Or is that more of an aspiration at this point? The vibe I got from the landing page was that it's a standalone app.

This would really work well for teams. Are there any limits into how many people can collaborate on Revise?
artursapek 5 hours ago
No enforced limits right now, but HN might find the performance bounds of my backend today. I am planning to add team/org accounts soon!

Looks nice, very nice.
Why don't you use your local open source llm, without the interaction of big models? I mean, more work, but you don't need to pay your cut to them. Just asking.
artursapek 4 hours ago
Yes, an eventual goal is to let Revise use a local LLM.
