What’s inside
Everything you reach for between the fridge and the bench
Built by a lab scientist for the jobs that eat your day: making up solutions, following a method you’ve done once before, and checking you’ve understood a technique before you waste reagents on it.
Protocols that run with you
37 ready-to-run templates, from Western blots to CRISPR knockouts, with tick-off steps, built-in timers and the right calculator at each step.
- Write your own or import from Word
- Export to Markdown, CSV or JSON
Technique videos
Twenty short, clear walk-throughs of the methods you’ll meet in a life-science lab, from gel electrophoresis to flow cytometry.
- Gel electrophoresis and UV-Vis are free
- Linked to the matching protocol
Learn & Check
Twenty-four technique modules: the principle, its history, strengths and limits, a worked example, then a 10-question quiz drawn from 50.
- Score 8 out of 10 to earn the badge
- Badges move you up five levels
Statistical Support
Answer a few plain questions about your data and get the right test, what to check first, how to report it, and ready-to-run code.
- Code for R, SPSS, Stata, SAS and jamovi
- Simple or technical wording
Ask Mark
Mark finds the right tool, works through a calculation, explains a method or helps you read a result. He replies in your language.
- 5 questions a month free
- 300 a month on Pro
Paper to protocol
Turn a methods section into steps you can tick off
Find the paper
Paste a DOI or PubMed ID, search Europe PMC, or upload the PDF.
Pick a method
Mark lists the methods it describes, with the reagents and equipment it names.
Run it
Save it as a protocol with timers and calculators in place, then tweak it for your lab.
Meet Mark
A lab tech who doesn’t mind being asked twice
Mark sticks to science and lab work. He won’t help with anything unsafe, and he’ll point you to your supervisor or biosafety officer when that’s the right call.
How do I make 500 mL of 1× PBS from a 10× stock?
MARKAdd 50 mL of 10× PBS to 450 mL of purified water and mix. Check the pH is 7.4 before you use it. Want me to open the dilution calculator so you can scale it?
Always double-check Mark’s answers before you rely on them at the bench.

Questions
Good to know
Where is my data kept?
Your protocols, saved results and progress are stored on your own device. If you make an account, your name and email are used to sign you in and to restore your plan. Export a backup at any time from Privacy and data in your profile.
Is Mark an AI?
Yes. Mark uses an AI model to answer questions and read papers. He’s told to stick to science and lab work, to refuse anything unsafe, and to keep units and chemical names in standard form. He can still be wrong, so check his answers before you rely on them.
How do I get the student price?
Verify a university email address (ending .ac.uk, .edu and similar) in your account and BenchMark Pro is £29.99 a year. We may ask you to confirm it again when your plan renews.
Can I use it without an internet connection?
Calculators, your protocols and timers work offline once the app has loaded. Mark, paper search, videos and new languages need a connection.
Can my department or company buy it?
Yes. Lab covers up to 10 people and is invoiced once a year. Campus covers up to 150 users with teaching tools and usage reports. Both are available as a free pilot first. Use the form below and we’ll reply with a quote.
How do I cancel?
Cancel in Plan and billing in your profile, or through the store you subscribed in. You keep your plan until the end of the period you’ve paid for.
