An AI-native online LaTeX editor built by Murple Inc. of South Korea. Its AI, trained on 5.4 million academic papers, provides context-aware completion, grammar correction, and automatic compile-error fixes to support researchers and students writing papers. The fact that even the free plan allows real-time collaborative editing with no cap on the number of collaborators is a major difference from the industry standard, Overleaf. It also supports pre-submission review report generation and Beamer slide creation, and since it runs entirely in the browser, no installation is required.
Key Features
- AI completion and grammar correction: An AI trained on 5.4 million academic papers provides context-aware LaTeX completion, grammar correction, and academic writing support
- Automatic compile-error fixes: The AI detects and fixes LaTeX compile errors on the spot
- Unlimited collaborators: Even the free plan has no cap on collaborators, so large co-authored projects incur no additional cost
- AI paper review: Before submission, it generates a review report cross-checked across multiple models, covering 8 reviewer perspectives and 7 scoring dimensions (the AI Paper Review feature)
- Beamer slide generation: Generates presentation-ready Beamer slides from your manuscript in a short time
Pricing
There are three tiers: Starter (free), Pro, and Enterprise. Pro pricing was verifiable on the official site, but the detailed feature limits of each plan (storage capacity, AI usage quotas, and so on) are served as dynamic content and could not be confirmed for this article.

Pros and Cons
✅ Pros
- No limit on collaborators even on the free plan, so large co-authored projects incur no cost
- AI completion and grammar correction grounded in 5.4 million academic papers makes writing approachable even for those new to LaTeX
- Pre-submission AI review and Beamer slide generation support the whole path from writing to presentation prep in one place
- Runs entirely in the browser with no installation, so there is no environment setup to deal with
⚠️ Cons
- A relatively new product from a startup founded in 2022; its track record and ecosystem (template count, breadth of university partnerships) are still limited compared with Overleaf
- The detailed limits of the Pro plan (AI usage quotas and so on) are hard to confirm statically from the official site, so you will want to check individually before subscribing
- The officially confirmed interface languages are English and Korean; Japanese support is unverified

Who It’s For
- Researchers and students who want to co-write conference or journal submissions with multiple authors in real time
- Anyone unfamiliar with LaTeX syntax errors and compile errors who wants AI assistance while writing
- Anyone who wants to surface reviewer-perspective weaknesses through an AI self-review before submission
- Anyone who needs to prepare conference presentation slides quickly from a manuscript
- Anyone for whom Overleaf’s per-seat pricing is a blocker and who wants to try large-group collaborative editing for free
Conclusion
Murfy is a relatively new LaTeX editor built around AI completion and review, and its biggest differentiator is that it sets no cap on collaborators even on the free plan. Completion, grammar correction, and error fixes powered by an AI trained on 5.4 million academic papers deliver the most benefit to researchers and students who are less comfortable with LaTeX. On the other hand, the service launched in 2022 and does not yet have Overleaf’s track record, and the detailed limits of the Pro plan are hard to read from the official site — so if you are considering paying, confirm the specifics before you subscribe.
