The Best Collaborative LaTeX Editor for Research Teams & Labs
By Shihab Shahriar Antor · Updated October 2026 · 7 min read
For a research team, the best LaTeX editor is one with real-time collaboration, unlimited co-authors, and a single shared compile, so an entire lab writes one paper together instead of emailing .tex files back and forth. LetX runs in the browser, collaborators are free on every plan, keeps unpublished work private (never used to train AI), and builds every author against the same toolchain for reproducible output.
The Team plan
Team is for labs, groups and classes of 2 to 50 people: $20 per seat a month or $200 a year, on one bill. A seat gives one person Pro: unlimited compiles, longer builds, full version history, GitHub import and export, a monthly Lexi allowance and connecting Claude or ChatGPT. Everyone else in the group edits shared projects free, because collaborators are free on every plan.
- Who needs a seat: only the people who need Pro. A lab of six where two people need unlimited compiles and full history buys two seats, $400 a year.
- Running it: members, roles and an activity log, and you can move a seat to someone else at any time.
- Billing: added seats are charged for the rest of the period, fewer seats take effect at the next renewal, and you can cancel any time.
- More than 50 people: a department or a university uses an Institution plan. A course of any size can start from LaTeX for classes.
Give Pro to the people who need it, on one bill.
Start a teamTeam on LetX and group plans on Overleaf
On Overleaf, how many people can edit a project depends on its owner’s plan: 1 collaborator on Free, 10 on Standard and unlimited on Pro. Group seats cost $119 (Standard) or $239 (Pro) a year each for groups at degree-granting institutions, and $179 or $359 for other groups (Overleaf’s plans page, read on 8 October 2026). On LetX, collaborators are unlimited on every plan, including Free, so a seat ($200 a year) is only for someone who needs Pro. If your group only needs to write together, LetX costs nothing; if everyone needs paid features, an Overleaf education Standard seat costs less than a LetX Team seat.
What a research team needs from a LaTeX editor
Writing LaTeX alone is solved; writing it as a group is where most tools break down. A lab pushing a paper to a deadline has five people touching one manuscript, a supervisor reviewing drafts, and a shared bibliography that must stay consistent. The classic email-and-merge workflow produces stale drafts, version-mismatch compile errors, and lost edits at exactly the wrong moment.
- Real-time co-authoring: everyone edits one live document with shared cursors, not separate copies.
- Unlimited collaborators: collaborators are free on every plan, so cost never caps the team.
- One reproducible compile: all authors build against the same server toolchain; no local TeX drift.
- Privacy for unpublished work: documents are private by default and never used to train AI.
- Git/GitHub integration: on Pro, import and export projects with GitHub so LaTeX fits an existing research workflow.
- Institutional templates: university thesis and journal formats are ready to open.
Real-time collaboration without paying per collaborator
The hidden tax on collaborative LaTeX is per-collaborator pricing: editors that meter how many people can edit a project at once force a lab to ration seats or pay per head. LetX puts the whole team on one project in real time without that cap, a fit for groups that grow each semester and for distributed collaborations spanning several institutions.
When several people in the group need Pro (unlimited compiles, full version history, GitHub), the Team plan puts their seats on one bill: $20 per seat a month or $200 a year, for 2 to 50 people. A seat is only for someone who needs Pro; everyone else keeps editing shared projects free.
LetX vs Overleaf for research groups
| Overleaf (typical) | LetX | |
|---|---|---|
| Real-time collaborators | Capped by paid plan | Unlimited |
| Compile | Queued on free tier | A few seconds on dedicated workers |
| Unpublished-work privacy | Per policy | Private by default, never AI-trained |
| Git / GitHub | Paid plans | Import and export on Pro |
| Institutional licensing | Per-seat negotiation | Team seats for 2 to 50 people; Institution plans for more |
Privacy for unpublished research
For an unpublished paper or a thesis under embargo, where the text goes matters as much as how it compiles. On LetX, projects are private by default and your documents are never used to train AI models, the differentiator that matters most to labs and to university research groups evaluating an Overleaf alternative.
Set up your lab in minutes
A shared project takes a minute to set up and works the same for two people or a whole department. Start from real-time collaborative editing, open an institutional thesis template, and bring existing work in as a .zip, or from GitHub on Pro.
Put your whole lab on fast, private, real-time LaTeX.

How much does the Team plan cost?
Team is $20 per seat a month or $200 a year, for 2 to 50 people on one bill. Collaborators are free on every plan, so a seat is only for someone who needs Pro.
What is the best LaTeX editor for research teams?
The best LaTeX editor for a research team is one built for real-time, multi-author writing: shared live editing, unlimited collaborators, and a single reproducible compile. LetX provides all three in the browser with no install, and collaborators are free on every plan, so an entire lab co-writes one paper instead of merging emailed files.
Which LaTeX editor is best for real-time team collaboration?
LetX is built for real-time team collaboration: co-authors edit the same document live with shared cursors and compile against one server toolchain. Unlike editors that meter collaborators on paid tiers, LetX puts the whole team on a project without limits.
What's the best LaTeX editor for distributed research teams?
For distributed teams spanning several institutions, a browser-based editor with real-time sync removes the install and version-mismatch problems entirely. Everyone on LetX works in the same live project from any device and gets the same reproducible PDF, which is why it fits cross-institution collaborations.
Can multiple people edit the same LaTeX document at once?
Yes. LetX uses real-time collaborative editing, so multiple authors edit one LaTeX document simultaneously with live cursors, no copy-merge step and no overwriting each other.
Does LetX limit the number of collaborators?
No. Collaborators are free on every plan, so a research group can add the whole team to a project without per-collaborator fees capping the size of the lab. A Team seat is only for someone who needs Pro.
Is unpublished research kept private on LetX?
Yes. Projects are private by default and your documents are never used to train AI models, which is the key concern for unpublished papers and embargoed theses. For a whole group, the Team plan covers 2 to 50 people, and Institution plans cover larger groups.
