Use it for browser work, not system power management
A browser session helper is best for web apps that expect occasional activity in a supported tab. It is different from a desktop utility, a power management tool, or a physical device.

Long-running browser work needs a clear status signal. Session Activity Helper helps supported Chrome tabs stay active with visible browser-only activity, local diagnostics, and optional Pro site profiles for repeat workflows.
Browser-only activity for supported pages. Session Activity Helper does not override site, workplace, school, browser, device-management, or admin-controlled session rules.

Different sites respond differently. A low-noise pointer recipe can be enough for some pages, while others may need a pointer plus mouse recipe or a tiny scroll nudge. Pro is where repeat workflows become easier to tune and save.
The key question is not whether the extension is on. The useful question is whether this page was supported, what recipe ran, and when the last local pulse happened.
Free is the right starting point when you need one visible manual test. Pro is for repeat sites, saved profiles, advanced recipes, longer visible run windows, and exportable diagnostics.
Compare Free and ProFAQ
The honest limits matter. They reduce support load and make Pro upgrades more durable.
Dashboards, queues, CRMs, admin tools, and training portals are the strongest fits when they run in normal supported Chrome tabs.
The free tier is designed around active visible-tab use. Pro workflows are built around repeat profiles and more advanced control, while still respecting browser limits.
Reloading can destroy unsaved state, restart a video, lose filters, or interrupt admin work. Visible browser activity is a lower-friction first test on supported pages.
Next step
Add the extension, open the page that keeps timing out, run Test this page, and start a visible session. Pro is for repeat sites and longer workflows.
