Octree

Octree positions itself as the 'modern Overleaf alternative,' and for good reason: it's open-source, AI-native, and surprisingly cheap. The free trial gives you three days of unlimited edits, and the Pro plan runs at $2.49/week—far less than Overleaf's $15/month for premium features. If you're a researcher who writes LaTeX daily, that math is hard to ignore. We'd reach for Octree when we need to quickly generate a conference paper from a prompt, or when we're stuck on a complex TikZ diagram and want an AI to suggest the code. The template library, with 71+ options including NeurIPS 2026, saves setup time. The conversion tools (Math to LaTeX, Excel to LaTeX) are niche but useful. Where it bites: PDF preview and real-time collaboration are still marked 'coming soon.' That means no live preview while editing, and no multi-author editing without sharing the whole doc. For teams or those who need instant visual feedback, Overleaf remains the safer bet. Compared to Overleaf, Octree is faster for AI-assisted writing but slower for collaborative editing. If you're a solo researcher who values AI suggestions and open-source transparency, Octree is worth the switch. If you're collaborating heavily or need offline access, Overleaf or a traditional TeX distribution may serve you better. In practice, Octree's strongest use case is for individual researchers preparing submissions to top-tier conferences. The AI autocompletion and TikZ generation are genuinely helpful, and the price is right. For larger teams or those requiring a stable, mature workflow, wait until the collaborative features arrive.
