Octree
AI LaTeX editor: write research docs, generate TikZ, export PDF
Octree is a solid, cost-effective choice for solo researchers and students who want AI-powered LaTeX writing. The TikZ generation and natural-language drafting are genuinely useful, and the free trial makes it risk-free. Just don't expect it to replace Overleaf yet—real-time collaboration and live PDF preview are still coming soon.

AI document generation is only available on the paid Pro plan, so the free trial gives you the editor but not the core AI drafting feature.

About Octree
Octree is a browser-based AI LaTeX editor that helps you write research documents without wrestling raw LaTeX. You describe what you need in plain English, and the AI drafts text, generates TikZ diagrams, structures sections, and offers intelligent autocompletions as you type. It's built for researchers, students, and teams who want a modern, free alternative to Overleaf—no setup, no syntax hurdles. Octree's standout features include AI-powered document generation, image-to-TikZ and math-to-LaTeX conversion tools, and a citation generator that keeps your workflow in one place. You can import existing .tex files, convert from Math, Excel, or Markdown, and choose from 71+ templates covering research papers, theses, CVs, and conference formats like NeurIPS 2026 and ICML 2026. A built-in PDF preview and real-time collaboration are listed as coming soon, while exports to PDF and sharing are already available. The entire codebase is open source, with an active community on Reddit and Discord, and transparent pricing that includes a free 3-day trial. For individual researchers and academics who want AI assistance without the learning curve, Octree positions itself as a practical, community-driven alternative to proprietary suites like Overleaf, with a focus on AI-native writing and diagram generation. One caveat: PDF preview and real-time collaboration are still on the horizon, so if you need those today, you'll be waiting. But for solo writers and students, the current feature set covers the essentials—write, generate diagrams, and export.
Behind the Verdict
Octree aims to be the 'modern Overleaf alternative' and largely succeeds for individual researchers and students. Its core strength is the AI-assisted writing flow: you can describe a document in plain English, and it drafts LaTeX, suggests edits, and generates TikZ diagrams from text. The conversion tools (image to TikZ, math to LaTeX, Excel to LaTeX, Markdown to LaTeX, MathML to LaTeX) are genuinely useful for converting existing content. The 71+ templates cover common academic formats, including NeurIPS 2026 and ICML 2026, which is a nice touch for conference submissions. Being open source is a differentiator, and the community on Reddit and Discord is active. However, there are notable gaps: PDF preview is 'coming soon', so you can't see your compiled output live—a significant workflow friction for LaTeX users. Real-time collaboration is also pending, which limits team usage. The pricing is simple and affordable, but the Pro tier is billed weekly at $2.49, which might feel odd for some. Enterprise offers private hosting and 10+ integrations, but no specific integrations are listed on the site. For solo academics and students, Octree is a practical choice, but if you need collaboration or offline editing, you'll be waiting.
