The same share flow, one click on a laptop

ChromeComing to the Chrome Web StoreFree

Overview

Long videos get watched on a laptop, so the share flow has a desktop version. Prysm for Chrome is coming to the Chrome Web Store. Setting it up takes a minute: install it, click the Prysm icon in the toolbar, and sign in with the email of your Prysm account. Prysm emails you a 6-digit code; there is no password, and the extension never creates an account, so get the app first. Then open a video about a game. A Save to Prysm button sits in the bottom-right corner. Click it and a small panel shows the game it found, large, with Add to my backlog underneath. If the guess is wrong, Not it? opens the other candidates and a search box. On any other site, the toolbar button does the same for the page you are on, and Alt+Shift+P opens it from the keyboard.

How it works

  1. 1

    The extension is a second client for the same two backend functions as the phone's share sheet. The panel sends the page's address to the resolve step, shows what comes back, and calls the confirm step only when you pick a game. The saved link is the clean video address, without tracking parameters, and it shows on the game page in the app as the Saved from card does.

  2. 2

    The extension can read the page, which the backend cannot. When you click Save, it reads the title, caption and hashtags you can see, and on YouTube the game named in the Games card. It sends them as hints. This matters most on Instagram, whose captions the backend cannot fetch: on a laptop, the extension reads the caption for it. Nothing is read or sent until you click.

  3. 3

    Your sign-in lives only in the extension's background worker. The button on the video page asks the worker to act and never sees a token, and the code is typed only into the extension's own page, never into a website.

  4. 4

    The panel sits in a closed shadow root. Keys typed into its search box are stopped before the video site sees them, so typing a “k” or an “f” does not pause the video or make it full screen.

  5. 5

    The free limit applies here too. If your free library is full, the panel says so and points to Prysm Pro in the app, and the link is still saved.

Key decisions

Reuse the share flow, add nothing new

The extension has no matching logic of its own. The backend that names the game for a TikTok on your phone names it for the same TikTok in Chrome, so an improvement to one improves both. The only backend change was accepting the page hints.

Always confirm, as on the phone

The same rule as the share sheet: nothing goes into your library without a click, and a confident guess only means the game is shown large.

A small permission list

The extension asks for storage and for access to the current tab when you click its icon, and runs on the three video sites to show the button. It needs no access to other sites and does not read your history.
