User Reviews

Most users praise Speed Booster for significantly cutting memory usage and lag in long ChatGPT chats, restoring usability and responsiveness. The extension is loved by many and considered essential, with some willing to pay for Pro. Common criticisms focus on paywall concerns, privacy and data-sharing worries, occasional inconsistency in effectiveness, and specific issues like forgetting context in non-rendered parts or input lag on long conversations. A few report intrusive permissions prompts.

Pros

Significant memory usage reduction and smoother performance on long chats.
Makes long conversations usable again by reducing lag and freezes.
Widely positive user sentiment; many call it essential, with some willing to pay for Pro.
Easy to enable and configure with sensible defaults.
Valued by heavy users and complex projects as a must-have tool for long chats.

Cons

Paywall / Pro licensing criticisms; free version seen as limited or the product behind a paywall.
Privacy concerns about data collection or sending data to external servers and licensing checks.
Inconsistent effectiveness; not always an improvement and some reports of little or no gain.
Specific reliability issues: it can forget context from non-rendered chats and introduce input lag on very long chats.
Intrusive permission prompts or warnings tied to updates or licenses; perceived as spammy or suspicious.

Recent reviews

It's actually really good, but it constantly alerts you to upgrade to pro when it activates, which can get quite annoying after a while.
