Why Overleaf AI Isn't Enough (Technical Breakdown)

The Problem with Bolt-On AI

Overleaf added AI features. But there's a fundamental problem: AI was retrofitted onto a system not designed for it. Here's a technical breakdown of why that matters.

Architecture Matters

Overleaf's Architecture:

• Document stored as flat text files

• Compilation happens on shared VMs

• AI has limited context window

• No awareness of multi-file projects

What this means: When Overleaf's AI tries to help, it only sees fragments. It can't understand that your \input{chapters/intro} references another file. It can't see your bibliography. It's working blind.

The Context Problem

Modern AI models are powerful, but they need context. Overleaf's AI typically sees:

• The current visible text

• Maybe 1000 lines around your cursor

• Error messages from the log

It does NOT see:

• Your custom .sty files

• Related chapters

• Previous versions

• Your full bibliography

Why This Breaks in Practice

Scenario: You have a custom command \mytheorem defined in preamble.tex

Overleaf AI: "Unknown command \mytheorem. Did you mean \theorem?"

Octree AI: Sees your preamble.tex, understands \mytheorem, offers relevant suggestions based on YOUR definitions.

The Solution: AI-First Architecture

Octree was built from the ground up with AI in mind:

1. Full project context: AI sees all your files 2. Intent understanding: We parse what you're trying to do, not just what you typed 3. Safe editing: AI proposes changes you preview before applying 4. Learning: AI understands your document's patterns

Performance Implications

Because Overleaf's AI is an add-on, it creates latency. Every AI request requires:

• Serializing document state

• Sending to separate AI service

• Waiting for response

• Deserializing back

Octree's integrated approach means AI responses feel instant because there's no translation layer.

The Bottom Line

Adding AI to a legacy system is like adding electric motors to a horse carriage. It might move, but it wasn't designed for it. Octree is the Tesla — built electric from the start.
