Zooniverse: help real researchers with citizen science projects
Zooniverse lets anyone help real researchers by classifying images, records and videos. Its pages ask for no background and show no price, though they never say "free" outright.

What it is
Zooniverse is a website where anyone can help real researchers by looking at their data. Its About page calls it "the world's largest and most popular platform for people-powered research". Projects ask you to do things like study images of faraway galaxies, read historical records and diaries, or watch videos of animals in their natural habitats. It is not an AI tool. We included it as a way to learn science by taking part. The platform is run by a collaboration of institutions in the UK and US, per its FAQ.
Is it free?
No official page we read uses the word "free" or lists a price. Zooniverse describes its contributors as volunteers and says you can do "as much or as little as you'd like", with no minimum time. The pages we read list no participation fee or paid plan. We did not create an account or test the registration process. The FAQ also points to a donation page, which is optional. So the plain answer is that taking part looks free, but Zooniverse does not state it in those words.
What you can do with it
- Classify data in a project. Pick a project on the Projects page and follow its steps. The About page says you do not need any specialized background, training or expertise.
- Track your effort. Registered volunteers get personal stats and can generate a volunteer certificate, per the Volunteer page and FAQ. The FAQ says the certificate can be used for service learning requirements.
- Join the discussion. Registered users can post on Talk boards and ask questions of researchers.
How to get started
- Open the official Zooniverse website and register for an account. Under-16s need a parent or guardian to sign off.
- Visit Projects and choose a subject that interests you.
- Read the project instructions, Help and Field Guide before submitting classifications.
- Start with a few items. There is no minimum time requirement.
- Use your personal stats to track your work. For a volunteer certificate, log in, open More Stats and choose Generate Volunteer Certificate.
What to watch out for
- Account and age. The Volunteer page says to register for an account. For those under 16, a parent or guardian needs to sign off on the registration.
- Your answers cannot be edited. The FAQ says that once you submit a classification you cannot go back and edit it.
- Projects vary. Each project is run by its own research team and has its own tasks and help. We did not try any project.
Privacy and data
- The FAQ says your classifications are stored in the Zooniverse database, and project research teams download their project's classification data.
- It points to the Zooniverse User Agreement and Privacy Policy page for data ownership. That page did not load as readable text for us, so we did not read it. Read it before you sign up.
India
- We found no India-specific limit on the pages we read. We did not check whether a given project is available in your region.
