From first search to finished draft.
One place for the whole research project: find papers, keep your evidence straight, check your references, analyse, write and submit. Made for medical students, residents, clinician-researchers and grad students in any field.
We're opening Lattice to a small group first. Join the waitlist and we'll email you when it's ready.
Built by medical students, for people who write research.
Medical students and residents
Write your first papers without juggling PubMed, Zotero, Word, the IRB and the journal's rules.
Clinician-researchers
Evidence tables, IRB drafts, CONSORT and STROBE checks, reviewer replies and data from de-identified case notes, in one project.
PhD students
Keep a growing library under control, ask it questions, and draft chapters from what you have actually read.
Master's students
Plan your thesis, check your references, find the right statistical test and proofread as you go.
Qualitative researchers
Code interview transcripts, group codes into themes, and export your excerpts.
Everything a research project needs, in one place.
One search for everything.
Search PubMed, OpenAlex, arXiv and more at once. Add papers by DOI, upload your own PDFs, or import your Zotero and EndNote files.
- An AI assistant to ask about your topic

Sample data
See the whole evidence at a glance.
Tag every paper as supporting, contradicting or not relevant, and keep every paper in one table you can download as Excel.
- Details that matter for your medical specialty pulled from each paper
- Notes attached to the exact passage
Sleep duration and working memory
Shorter sleep linked to lower scores
Late school start and grades
Small improvement after the change
Evening screen time trial
No effect on memory tests

Sample data
Answers that show their sources.
Ask a question about the papers you've saved and get an answer that points to where it came from, including the full text of PDFs you uploaded.
- Says so when your papers can't answer it
- 1. School start times and academic performance
- 2. Late school start and grades
Sample data
Your own columns, filled for you.
Name what you need, like sample size or main method, and Lattice reads each paper and fills the table. Then download it.
- "Not reported" when a paper doesn't say

| Paper | Sample size | Design |
|---|---|---|
| Sleep and memory | 412 | Cohort |
| School start times | 1,840 | Quasi-experimental |
| Screen use trial | 96 | RCT |
Sample data
Know when the evidence changes.
Your search keeps running after you close the tab, and flags new papers, including ones that contradict what you've found.
- New evidence and contradictions, kept apart
New trial finds no link between screen time and memory
Conflicts with 2 papers in your evidence table.
Large cohort extends earlier sleep findings to age 16
Found by your standing search, 2 days ago.
2 unread. Your search keeps running after you close the tab.
Sample data
First drafts, in your own structure.
Draft a thesis, a journal paper, a literature review or a research proposal from your evidence, with real citations in seven styles.
- Your methods and results stay as placeholders
- Never invents data or sources
Chapter 3: Methodology
This study uses a cross-sectional survey design, following approaches reported in earlier work on adolescent sleep (Okafor, 2021; Lindqvist and Haas, 2019).
[Describe your sample here: who took part and how they were recruited]
Seven citation styles. Your own methods and results stay as placeholders, never invented.
Sample data
Proofread, and catch copied text.
Get grammar and clarity fixes, and see passages that match your saved sources word for word, so you can quote or rephrase them.
- Not a full plagiarism checker: it compares with your own library
Students who less worse on memory tests.
Click a wavy word to accept the fix.
Matches a saved source
“…associated with reduced working memory performance and increased risk of…” (17 words) from Sleep duration and working memory.
Proofreading plus a copied-text check against your own library.
Sample data
Citations in Word, in any style.
Insert citations from your Lattice library into a Word document, then switch between APA, Vancouver, AMA, Nature, the Lancet and thousands more. The citations and the reference list reformat together.
- Works with Word on Windows, Mac and the web
- Your BibTeX and RIS files still import and export

Pick a style and the citations and list reformat. This runs the real citation engine.
Sample data
Does your paper say what journals expect?
Pick CONSORT for a trial, PRISMA for a review, ARRIVE for animal studies, or STROBE, CARE or COREQ, and see which points your draft covers and which are missing, with the sentence it found.
- Draws the CONSORT flow diagram for randomized trials
- Checks what the paper says, not how good the study is
- Reported1aThe title says it is a randomized trial.
- Reported7aExplains how the sample size was decided.
- Reported8aSays how the random allocation sequence was generated.
- Missing9Describes how the sequence was kept hidden until participants were assigned (allocation concealment).
- Unclear11aSays who was blinded after assignment (participants, carers, assessors) and how.
- Reported13aGives, for each group, the numbers randomised, who received the intended treatment, and who was analysed for the primary outcome.
- Missing19Reports all important harms or unintended effects in each group.
- Reported23Gives the trial registration number and the name of the registry.
5 of 8 shown are reported
Click a checklist. Each point shows the sentence it found in your draft. Trials also get a flow diagram builder.
Sample data
Check every reference.
Find references that don't exist, point to the wrong paper, or have been retracted, before a reviewer does.
- Free, and it needs no AI
- Works on your library or any list you paste
Sample data
The right test, and enough people.
Pick the right statistical test for your design, work out your sample size, and get your results explained in plain language.
- Doesn't run your analysis; use R, SPSS, Python or Excel
Suggested test
Welch's t-test (independent samples)
Runs the real test chooser and sample-size calculator. Plus plain-language help reading your output.
Sample data
Qualitative coding, by hand.
Add anonymised interview or focus-group transcripts, tag passages with codes, group them into themes and export your coded excerpts.

Sample data
Write with your co-authors, live.
Everyone edits the same draft at the same time. Drag evidence in as you write, then send it to Word or Google Docs.
