Revise: The AI Editor Born to Challenge Google Docs and Microsoft Word

While Google Docs and Microsoft Word bolt AI features onto bloated legacy codebases, one solo developer spent 10 months building Revise from scratch — a lightweight, canvas-based editor where AI isn't an add-on, it's the whole point.

Revise just launched on Hacker News, and the response couldn't come at a better time.

As the document editing market faces a perfect storm — users tired of paying $129/year for "AI features" that feel like stickers on a Word processor, companies demanding better AI integration without bloated suites, and hackers demanding open alternatives — Revise answers with a completely new approach. And it's built by an indie hacker, not a Fortune 500 engineering organization.

This is your indie developer story. How one person took on giants with superior UX, open architecture, and AI that actually earns its keep.

The Indie vs. Giant Battle Plan

Revise's developer, who spent 7 months working full-time (and 3 additional weekend months) to build the product, has an unorthodox vision.

Canvas-based rendering beats contenteditable divs.

Most web editors use "contenteditable" divs for document editing — essentially giving the browser's editable div as a document editor, the same approach used by Google Docs and Facebook's Notes feature. This approach creates memory leaks, performance issues, and editing limitations as documents grow long.

Revise instead uses a canvas-based rendering engine. Instead of manipulating DOM elements, the editor renders documents as a canvas layer, then uses Y.js CRDT for real-time collaboration. This is the same architecture used by Figma and Miro, products Revise competes with.

Ai integration from day one.

AI isn't an afterthought. Revise has three AI models integrated from the start: OpenAI, Anthropic, and xAI models. Each has its own settings panel where you can adjust temperature, top_p, presence penalty, and frequency penalty. You can even toggle models off and use plain vanilla text editing for quick notes.

The developer chose this path deliberately:

This architectural choice matters. TipTap and ProseMirror are great for notes and chat interfaces. But for serious document editing with AI assistance, Revise's custom engine delivers the performance and UX that established players don't prioritize.

AI That Actually Helps You Write

Revise's AI assistant doesn't float in your sidebar as a chat interface. It lives inline with your document, reviewing changes in real-time as you edit.

Proofreading That Feels Human

When you save a document, Revise's AI proofreader:

What's brilliant: the AI doesn't just correct errors. It displays each change inline, letting you see the rationale behind every suggestion. Hover over a change and you'll see the AI's reasoning, whether it's checking grammar, tone, or clarity.

Malapropism detector.

Revise's AI spots malapropisms — using the wrong word that sounds right. For example, mistaking "aforementioned" for "forementioned". The AI flags these with context-aware suggestions, explaining why the replacement fits better.

PDF Extraction via Multimodal LLMs

Upload a PDF, and Revise's multimodal AI extracts content intelligently. It doesn't just OCR text. It:

This is how Revise treats documents: as living, breathing objects, not just text dumps.

Prompt Library for Power Users

Revise lets you save and reuse your favorite AI prompts:

You can create workflows for different use cases. Need to draft a marketing email? Save that prompt. Preparing an academic paper? Another prompt set. The product learns from your workflow.

A Free Tool That Competes With Paid Giants

Revise's core product is free. No subscription required, no paywall for basic features.

What you get for free:

The free tier is generous. But Revise explores premium tiers that offer unlimited exports, advanced prompts, priority processing, and team collaboration features. Early adopters on Hacker News expressed concern about the subscription model. This tension — free core product vs. paid premium features — is the eternal indie developer dilemma.

What Happened When Indie Hackers Showed Up

Hacker News response was positive: over 42 comments from users who appreciate the open architecture, canvas-based engine, and AI integration.

What users loved:

What users worried about:

These concerns are valid. But Revise proves something: indie developers can build serious tools that compete with giants, provided they focus on UX and specific workflows.

The Product Philosophy

Revise's philosophy is simple: AI belongs in editors, not as an afterthought.

Instead of adding ChatGPT buttons to existing interfaces, Revise built AI from the ground up. The editor and the AI assistant coexist in the same interface side-by-side. You can:

This is how AI should work in productivity tools: integrated, not tacked on.

Why This Matters for Indie Developers

Revise's story teaches lessons for indie developers entering AI-powered markets:

1. Focus on UX, not features

Revise didn't compete on features first. It competed on UX. Canvas-based rendering delivers smooth performance even with long documents. AI proofreading doesn't interrupt your flow. This user-first approach matters when competing with products loaded with features users don't use.

2. Choose your architecture deliberately

TipTap and ProseMirror are great for notes and chat interfaces. But for serious document editing, Revise's custom engine delivers the performance and UX that established players don't prioritize. Don't use default stacks when you can build something better.

3. AI from day one

Revise integrated AI models during development, not as a post-hoc addition. This enabled AI to shape the editor's design and UX. When you build AI-first, the AI becomes part of the product, not a feature to bolt on.

4. Open architecture builds trust

Revise's open source approach (Y.js CRDT, canvas rendering) builds trust with users. They can see how the editor works, not just magic buttons. Transparency matters when you're challenging incumbents.

The Road Ahead

Revise's journey is ongoing. The developer is iterating based on feedback. Early adopters are suggesting improvements for code highlighting, diagram editing, and AI model choices.

What's next:

But Revise has already achieved its goal: proving that indie developers can build serious AI tools that compete with giants.

Google Docs and Microsoft Word may have the resources, but they're shackled by legacy code and feature bloat. Revise is built for the AI era, from the ground up.

As more indie developers follow Revise's playbook, we can expect a wave of AI-powered alternatives that solve real problems — not just marketing fluff.

The future of document editing isn't AI bolted onto existing products. It's AI-native tools built from scratch. Revise is proving that this future is now.

FAQ

Can Revise work offline?

Currently, Revise is web-only and requires an internet connection for AI features. The developer plans to release a desktop app in the future that may offer offline capabilities with local AI model integration.

Which AI models does Revise support?

Revise integrates three major AI models: OpenAI, Anthropic, and xAI (Grok). Users can choose between them and adjust settings like temperature and top_p. The developer plans to add more models based on community feedback.

Is Revise free to use?

Revise's core product is free. You can proofread, edit, and collaborate without paying. Premium tiers offer advanced features like unlimited exports, priority processing, and team collaboration. The developer is exploring sustainable monetization while keeping the core functionality accessible.

Does Revise export to common formats?

Yes, Revise exports to PDF, DOCX, and plain text. The developer is working on more export options, including EPUB and Markdown for developer-facing audiences. PDF exports maintain high resolution and formatting integrity.
