Octree: The Open Source AI LaTeX Editor That’s the Smarter Alternative to Overleaf

For years, Overleaf has been the default choice for writing LaTeX online. It’s popular, it works, and it introduced countless students and researchers to cloud-based LaTeX editing.

But let’s be honest: Overleaf hasn’t kept up with how researchers, students, and technical teams actually work today.

LaTeX is powerful, but it’s also frustrating. Debugging errors wastes hours. Collaboration feels clunky. And advanced features like AI-assisted editing? They don’t exist in Overleaf’s workflow. On top of that, institutions and startups face steep subscription costs with little control over their data.

That’s why we built Octree — an open-source AI LaTeX editor designed from the ground up for speed, intelligence, and flexibility.

Octree isn’t just another editor. It’s the smarter, community-driven alternative to Overleaf.

The Problem With Overleaf

Overleaf earned its reputation by making LaTeX accessible in the cloud. But as workflows evolve, many of its limitations have become clear:

  • Expensive pricing for teams and institutions — especially at scale.

  • Proprietary platform — limited flexibility, no option to self-host, and little control over your data.

  • No AI capabilities — users are left to manually debug and fix formatting errors.

  • Performance bottlenecks — compilation times can lag on larger projects.

For researchers, quant teams, and students working under deadlines, these friction points add up. It’s time for an upgrade.

Introducing Octree

Octree is the first open-source AI LaTeX editor designed for the way modern research, engineering, and technical writing actually happens.

Here’s what makes Octree different:

  • 🚀 AI-Powered Diffing – Track, review, and apply changes intelligently with the help of AI.

  • ⚡ Faster Compilation – Optimized build workflows mean less waiting, more writing.

  • 🔗 Integrations That Matter – Connect Octree with the tools researchers and developers already use.

  • 🌍 Open Source by Design – Transparent, self-hostable, and community-driven.

  • 💸 Cost-Efficient – Free to use, with no expensive institutional pricing walls.

In short, Octree combines the best of modern AI with the freedom of open-source.
