Browser Extension

Alerts, ratings, and a timer for your Prolific studies

The extension sits next to Prolific in a sidebar or popup. It sends a desktop alert when a new study appears, and optionally a Telegram message to your phone. It shows each researcher's community rating for the studies on your screen, and it has a study timer. It is read-only. It never changes the Prolific page, and never signs in for you, and nothing personal leaves your browser.

You don't need the extension to use Prolific Tea.

The website works on its own. You can search researchers, read and write reviews, and see ratings and pay data at prolifictea.com without installing anything.

What the extension does and does not do

The extension watches the study lists and submission history that Prolific's own site already loads in your browser. It does not request study data from Prolific on its own, and it does not click, type, or change what Prolific's pages show. The "Reload Prolific" button in the popup reloads your Prolific tab, only when you click it.

Captured studies are uploaded only when you press Share on one study. Sharing never runs on a timer or in the background. Rating lookups and Telegram alerts, described below, are the only other times the extension contacts prolifictea.com. When you share, the extension asks, for each name on that study, whether it is the name of a person. A name you mark as a person is removed before anything is sent.

A rating is looked up only when you click a study's rating line or its arrow, or after you share a study whose rating you had already opened. The lookup sends the researcher's Prolific ID or name to prolifictea.com.

If you link Telegram, alerts go to your linked chat through prolifictea.com. An alert can show the researcher's name, as Prolific shows it. The site does not store that name.

Permissions in Chrome and Edge

  • storage: keeps your settings and captured studies on your device.
  • sidePanel: shows Prolific Tea in Chrome's sidebar.
  • notifications: shows desktop alerts.
  • offscreen: plays the alert sound.
  • Access to app.prolific.com: lets the extension read the study data Prolific's site loads from there.
  • Access to prolifictea.com: connects to the Prolific Tea site.

Permissions in Firefox

The Firefox build asks for storage and notifications (same use as above), access to app.prolific.com and prolifictea.com, and the following:

  • webRequest, webRequestBlocking, webRequestFilterResponse: let the background script read the study responses Prolific's site loads. No code runs on Prolific's pages.
  • Access to internal-api.prolific.com: one of the addresses those responses come from.

You can check an installed extension's permissions on your browser's extensions page. The extension does not read your cookies or sign-in details. Questions go to hello@prolifictea.com.

Add to ChromeAdd to FirefoxThe Chrome version also works on Edge, Brave, and other Chrome-based browsers.

Get alerted to new studies

Turn on study alerts and you get a desktop notification, with an optional sound, when a new study appears. Studies that come back after being gone also trigger an alert, after a cooldown you choose.

Filter by minimum reward, pay per hour, available places, and keywords, so you only hear about studies worth taking. The extension never accepts or completes studies for you.

Alerts on your phone (Telegram)

Connect Telegram by scanning a QR code in the extension. The same filtered alerts then reach your phone while Chrome and a Prolific tab are running. Setup takes about a minute, and you can disconnect anytime.

Alerts come from your computer, so none arrive while it is asleep. Telegram is optional and linked only to your Prolific Tea account. We never see your Prolific ID, name, or password.

What it does

The extension reads the study lists your browser already loads. It shows the matching Prolific Tea rating in its panel, so you can check a researcher before you start. Open a study to go to that researcher's Prolific Tea profile.

It never changes the Prolific page, never logs in to Prolific, and makes no requests to Prolific on its own.

Sidebar or popup, your choice

Use the sidebar to keep Prolific Tea in view. Use the popup when a study needs the full browser width, because it floats over the page instead of shrinking it. The sidebar is the default; open Settings and choose Popup if you prefer it.

On current Chrome and Edge versions, a button in every view switches modes at once, and the timer keeps running. Older versions save your choice and ask you to close and reopen once. Browsers without a sidebar stay popup-only.

Time your studies

Prolific locks you in once you accept a study, so it helps to track how long it takes. Start, pause, and resume the timer with one tap. A small dot on the toolbar icon shows it is running, even when the panel is closed.

When you stop, it shows the minutes you spent, ready to copy into your review. The timer runs only on your device and sends nothing anywhere.

Sharing is manual, one study at a time

Sharing is never automatic. Captured studies are uploaded only when you press Share on a specific study.

When you do, it asks about each name on that study: is this the name of a person? Answer Yes, a person and that name is removed before the request leaves your browser. Answer No, an organisation or lab and the name is sent. Nothing is pre-selected, and Share stays disabled until every name is answered. The study title, reward and timing, country, Prolific account IDs, and the institution's name, logo, and link are sent, and a domain name shown as a name is sent too. Expand See exactly what is sent to read the data first.

Sharing is per study and per name, because one study list can mix universities, companies, labs, and people. Answer for the study in front of you, or share nothing. Ratings, alerts, and the timer work either way.

Sharing is switched off right now. Prolific Tea is not accepting shared studies, and the extension says so rather than pretending to send. Everything else works.

What it reads locally

It reads only the Prolific study data your browser already loads: your available study list and your submission history.

It keeps only the title, researcher and study IDs, reward, estimated and actual time, and outcome. It discards the study description and every other field. It stays on your device unless you share a study or a Telegram alert sends a study's details.

What it never collects

  • Your name, email, or any personal identifier.
  • Your Prolific participant ID: it is never read, stored, or transmitted.
  • Your Prolific password or session: the extension never signs in for you.
  • Anything from pages outside Prolific.

Questions and answers

Which browsers does it support?

Chrome, Edge, Brave, and other Chrome-based browsers use the Chrome Web Store version. Firefox has its own version on Mozilla's add-ons site, with a sidebar and a popup. The first time you open it, press Allow once to turn on ratings and alerts.

Is the extension free?

Yes. Prolific Tea runs on donations, not ads. The extension shows no ads and asks for no payment.
