Murfy AI Review (2026): Pricing, Features & Honest Verdict

TLDR

Murfy AI is an AI-native online LaTeX editor and Overleaf alternative for research teams. It offers real-time collaboration with unlimited co-authors, compiles about twice as fast as Overleaf, and adds AI paper review and error fixing. Best for: academics who want speed and cheap collaboration. Price: free Starter, Pro about $20/mo. Rating: 7.4/10.

What is Murfy AI?

Murfy AI is a browser-based LaTeX editor built to replace Overleaf for people who write research papers. At its core it is the familiar split-screen setup: LaTeX source on one side, a live rendered preview on the other. What Murfy adds is speed, real-time collaboration with unlimited co-authors, and AI woven into the writing process. It fixes compile errors, autocompletes code, and can run an AI paper review that simulates feedback from several reviewers before you submit. It ships with a template library for common conferences, journals, and theses so you are not starting a manuscript from a blank file.

The product is made by Murple Inc., a South Korean company based in Seongnam-si, and the team says it serves more than 180,000 researchers across 120-plus countries. We dug into it because Overleaf has become the default for collaborative LaTeX, and defaults get complacent. Murfy’s whole reason to exist is that Overleaf can feel slow on big documents, gates collaboration behind per-seat pricing, and only recently added meaningful AI. Murfy attacks all three at once, and in 2026 it has picked up momentum as researchers look for a faster, cheaper home for their papers.

What Are Murfy AI’s Key Features?

Faster compilation

Speed is Murfy’s headline claim: up to 2x faster compilation than Overleaf. On a short document you will not notice, but on a long thesis or a paper heavy with figures and references, shaving seconds off every recompile adds up over a writing session. The free Starter plan caps compiles at a 30-second timeout, while Pro extends that to 5 minutes and unlocks the fastest compile speed, which matters if your document is genuinely large.

Real-time collaboration with unlimited co-authors

This is the feature that will convert Overleaf users. Murfy allows unlimited collaborators on every plan, including the free one, with no per-seat charge. That is a direct shot at Overleaf, where sharing a project with more collaborators pushes you up the pricing tiers. You get comments, track changes, and live co-editing, so a whole lab can work in one project without anyone doing the math on seat counts.

AI paper review and error fixing

Murfy’s AI does two useful things. First, when a compile fails, it suggests corrections presented as diffs, so you can see exactly what it wants to change and accept or reject it rather than blindly pasting a fix. LaTeX errors are famously cryptic, and this alone saves time. Second, the AI paper review simulates peer feedback from multiple reviewers, giving research-tailored language suggestions that go beyond a generic grammar checker. Both run on AI credits. The paper review is the more interesting of the two, because it targets the exact anxiety every researcher has before submitting: will a reviewer tear this apart for something I could have caught myself. Getting a rough simulation of that feedback in the editor, framed as research-tailored language suggestions rather than red squiggles, is a real step up from pasting your abstract into a general chatbot and hoping for the best.

Templates and version history

The template library covers conferences, journals, and theses, so you can match a target venue’s formatting without hunting for a class file. Version history is included, though the free plan only keeps 24 hours of it; Pro unlocks full history, which you will want if you are working on a manuscript over weeks or months and need to roll back a bad edit from last Tuesday.

How Much Does Murfy AI Cost?

Murfy AI starts free and stays free if your needs are modest. The Starter plan costs nothing forever and includes 1,000 AI credits per month, unlimited projects, unlimited collaborators, 24-hour version history, and a 30-second compile timeout. For a student writing the occasional paper, that is a complete, usable product without spending a cent.

Pro costs about $20 per month, billed around ₩29,000, and drops to roughly ₩21,750 per month if you pay yearly, a 25 percent discount. Pro raises AI credits to 20,000 per month, unlocks the fastest compile speed and a 5-minute timeout, gives you full version history, and adds priority support. Enterprise is custom-priced and layers on organization admin, a dedicated account manager, and custom onboarding for universities and larger labs.

The value story is strong when you compare against Overleaf. Overleaf raised its Standard plan to about $21 per month in 2026, and Professional runs about $42 per month, both priced per user. Murfy comes in slightly cheaper than Overleaf Standard while giving you unlimited collaborators instead of charging per seat. If you write with co-authors, Murfy’s per-team economics can be dramatically cheaper. The one caveat is credits: heavy AI users will burn through the free 1,000 quickly, which is really the nudge toward Pro. Worth doing the arithmetic before you commit. A three-author paper on Overleaf Standard is three seats at about $21 each, so roughly $63 a month, while the same team on Murfy Pro is one $20 subscription with everyone else invited for free. For a lab running several concurrent projects, that gap compounds fast and is the single most persuasive reason to switch.

Who is Murfy AI Best For?

Use Murfy AI if you are an academic, graduate student, or small research lab that collaborates on papers and is tired of Overleaf’s compile timeouts or per-seat pricing. It is a particularly easy win if your main frustrations are speed and the cost of adding co-authors, because Murfy fixes exactly those two things. If AI writing help and error fixing are appealing rather than threatening, that is a bonus on top.

Skip Murfy AI if you are a LaTeX power user who leans on Overleaf’s deeper, more mature tooling, integrations, or niche features, because Murfy’s interface is deliberately simple and the feature set is thinner. Skip it too if you cannot tolerate the occasional rough edge that comes with an earlier-stage product, or if you would rather not touch the cloud at all, in which case a local editor is the better home.

Best Murfy AI Alternatives

Overleaf

Overleaf is the incumbent and the most feature-complete collaborative LaTeX editor, with a huge template library, mature integrations, and the widest institutional adoption. Standard costs about $21 per month and Professional about $42, both per user. It is the safer choice if you need depth, reliability, and features Murfy has not built yet. The trade-offs are slower compiles on big documents and per-seat pricing that gets expensive for teams. If money and speed are no object, Overleaf is still the default.

Papeeria

Papeeria is a lower-cost online LaTeX editor with a free tier and cheap paid plans, plus built-in plot and diagram tools and Git integration. It is less polished and less AI-focused than Murfy, but it is a solid budget pick for individuals who want collaboration without a big subscription. If your priority is the lowest possible cost and you do not care about AI paper review, Papeeria is worth a look before you pay for anything.

TeXstudio

TeXstudio is a free, open-source, offline LaTeX editor you install on your own machine. There is no cloud, no subscription, and no credits, just a fast, powerful editor with excellent autocompletion and error highlighting. The catch is that real-time collaboration is not built in, so you handle sharing through Git or Dropbox yourself. For a solo researcher who values privacy, control, and zero cost over live collaboration, TeXstudio is the classic choice.

Final Verdict: Is Murfy AI Worth It?

Murfy AI does exactly what a good challenger should: it picks the incumbent’s weak spots and hammers them. Compiles are genuinely faster, collaboration is unlimited and free of per-seat tax, and the AI error fixing and paper review are practical rather than gimmicky. For a lab or a student paying for co-authors on Overleaf, the math often favors Murfy, and the free Starter plan means you can test the whole thing without risk. We came away impressed by how much you get for about $20 a month, or nothing at all.

The 7.4 rating reflects a product that wins clearly on speed, collaboration economics, and value, but has not yet matched Overleaf on breadth or maturity. Power users will notice the missing advanced features, and the early-stage rough edges are real. If your workflow is standard academic writing and your pain points are speed, cost, and collaboration, Murfy AI is an easy recommendation and quite possibly a straight upgrade. If you depend on Overleaf’s deeper toolset, keep it, but keep an eye on Murfy, because it is closing the gap fast.
