Can you fix the study checking time to the old. The old version checked once for 1 minute, but now it took longer and checked once for about 3 minute, that made us miss studies.

Andra Cornelia2026年3月30日

Unfortunately the sound stopped working, I see it is a common issue nowadays:(

Kandy Vien2026年3月29日

It was working fine a couple weeks ago. Then last week, I got the sound but no pop up for the study. Then a couple days ago, the sound completely stopped working. The extension is now useless to me and taking up space. Please fix this!

Shahar Dgani2026年3月29日

The sound stopped working a week ago and never returned

Rey More2026年3月29日

It was working fine then 3 days ago the sound stopped working on the extension. I've even contacted Prolific but no response yet.

Ivan Cheung2026年3月27日

What happened to the notification sounds in Google Chrome? They're just small beeps right now.

S J2026年3月26日

Imrana Jabeen2026年3月25日

AI product read

Monitors Prolific.com for new research studies and sends desktop notifications to participants when studies become available

Prolific participants miss time-sensitive study opportunities because they cannot constantly watch the Prolific website; the extension automates monitoring and alerts them immediately

Extension authenticates user via Prolific OAuth → periodically polls Prolific API for new studies → when studies are found, plays an alert sound and shows desktop notification → displays study count on the extension badge → user clicks notification or extension to go to Prolific and participate

Target users: Prolific research study participants looking to maximize their earnings by catching new studies quickly

background.js and chunks/popup-DcTuvAWh.js are heavily minified (single-line, ~79KB and ~288KB respectively), making it difficult to trace exact control flow and feature logic
Cannot fully confirm whether the OAuth flow is mandatory for basic functionality or if some features work without login due to minification
Cannot inspect the popup UI to see if there are upgrade/premium prompts hidden in the minified JS

Monetization

No paid features detected

No evidence of paid features within the extension. The 'upgrade' keyword hit is from generic React minified code, not a payment prompt. 'pro' hits are from the word 'prolific' or variable names, not a 'Pro plan'. 'license' is from Tailwind CSS MIT license comment. No subscription, payment, Stripe, billing, or premium feature gating found anywhere in the source code. The extension itself is free; Prolific as a platform has separate business models for researchers but those are unrelated to this extension's functionality.

Confidence: 90
Payment platform: --
Source: AI / Medium
Login required: Yes
Reason: The extension includes a full OIDC/OAuth client library in background.js, communicates with auth.prolific.com for authentication, uses access_token/refresh_token flows, and has the 'identity' permission. To monitor Prolific for new studies, the extension must authenticate the user against the Prolific platform to access user-specific study data via internal-api.prolific.com and api.prolific.com. Without a Prolific account session, the core workflow (fetching available studies for the logged-in participant) cannot function.
