No research,
no med school.

Admissions committees reject most applicants with no research experience. Marrow finds the professors whose work fits yours, writes cold emails that actually get replies, and gets you into a lab, before the spots fill.

Why research decides your application

Your GPA and MCAT won't set you apart. Research will.

At competitive programs, almost every applicant has the grades. The thing committees actually use to separate them is research: a lab, a poster, a publication, a professor who'll vouch for you. The students who get in didn't wait. They emailed early, got into a lab early, and had something real to show by application season.

The ones who didn't? They sent a handful of generic emails, heard nothing, told themselves they'd try again next term, and ran out of cycles. Don't be that applicant.

Why not just use ChatGPT?

A chatbot guesses. Marrow verifies.

ChatGPT can write one draft. It can’t confirm who’s currently at which lab, can’t cite real papers reliably, and can’t send, track, or follow up.

Invents professor names; can't confirm current affiliation
Real professors from a live index, current affiliation confirmed
Citations are often fabricated or out of date
Every claim links to a real paper and faculty page
Reads as AI; can't send or track anything
Drafts in your voice, approval-gated send, tracked pipeline
How it works
01
Find the right labs
Upload your resume or paste interests. Marrow ranks faculty by genuine research overlap, not keyword matching.
02
Drafts in your voice
Each email cites the paper that earned the match. Edit inline; Marrow learns your tone over time.
03
You approve every send
Nothing leaves Gmail without an explicit click. Track replies in one queue.

Every term you wait, the spots get fewer.

Professors take students in waves and fill up fast. The students who reach out first get the labs, and the rest spend another cycle wishing they had. Your three free matches take five minutes.

Move fast without losing control of your inbox.

Speed doesn't mean spam. We use Google's restricted Gmail scope. Marrow can only send drafts you click "Approve" on, never autonomously. Resumes are encrypted and deleted on request.

Pre-meds who didn't wait
Marrow drafted 23 emails in a weekend; I sent the ones I loved and got 6 lab interviews in two weeks. Two PIs said it was the most specific cold email they'd ever received.

I'd been meaning to email professors for a year and never did. With Marrow I was in a lab eleven days later. I genuinely think I'd have run out of time otherwise.

Everyone in my class was applying to the same three labs. Marrow surfaced one I'd never have found, whose last paper matched my thesis perfectly. That's the lab I joined.

FAQ

Common questions from pre-meds.

What is Marrow?+

Marrow is a research outreach copilot for pre-medical students. It finds professors across Canada and the US whose published work overlaps with your background, drafts personalized cold emails that cite the matched papers, and waits for you to approve every send.

Why does research matter so much for med school?+

Research is one of the highest-weighted experiences on a med-school application. The majority of successful applicants to competitive programs have hands-on research, and many have a publication or poster. With grades and MCAT scores clustered at the top, research is one of the few things that actually separates applicants. The students who start early get the letters, the posters, and the stories that committees remember.

Why is timing so urgent?+

Labs fill positions on a rolling basis, term by term. A professor who has space in September has none by October. Every week you spend staring at a blank email is a week other students are already in the lab. The earlier you reach out, the more open spots you're competing for, and the more time you have to actually produce something before applications are due.

Does Marrow send emails automatically?+

No. Every email requires an explicit click to send. Marrow uses Google's restricted Gmail scope and can never send autonomously. This is a core product rule, not a setting.

Who is Marrow for?+

Undergraduate pre-medical students (years 1–4) across Canada and the US actively applying to research labs. We index Canadian and US faculty.

How does Marrow match professors to me?+

You upload your resume or paste your interests. Marrow searches faculty pages across Canada and the US, parses recent papers, and ranks labs by genuine research overlap with your background, not keyword matching.

Is my data private?+

Yes. Resumes are encrypted at rest and can be deleted on request within 24 hours. Marrow uses a read-only Gmail scope and never reads your other mail. All traffic is TLS 1.3 and we never sell or share your data with third parties for marketing.

How much does Marrow cost?+

Marrow is free to start. Every account gets 3 searches and 3 drafts, no card required. There's no subscription. When you need more, you buy a one-time credit pack: Starter is $4.99 (10 searches, 25 drafts), Explorer is $11.99 (30 searches, 75 drafts), and Pro is $24.99 (75 searches, 200 drafts, plus Pro extras like voice fine-tuning and auto follow-ups). Credits never expire and there are no recurring charges.

What's the difference between a search and a draft?+

A search scans faculty pages and ranks labs by how well their research overlaps with yours. A draft is a personalized email Marrow writes for one of those professors, citing the paper that earned the match. You spend one credit per search and one per draft, so you only pay for what you actually use, and credits never expire.
