FAQ

Frequently asked questions.

Is Synapse free to use?
Yes. During the Beta period, Synapse is completely free with unlimited usage. We may introduce a Pro tier in the future for advanced features, but the core experience will remain free.
Does Synapse work on all websites?
Synapse works on virtually any website — news articles, documentation, dashboards, dApps, and more. Some sites with strict Content Security Policies may limit certain features, but the core summarization and context analysis always works.
Is this safe to use on banking and crypto sites?
Absolutely. Synapse runs entirely in your browser and doesn't transmit your data to any external server. It reads page context locally to provide you with insights. Your sessions, cookies, and tokens never leave your browser.
Why a bookmarklet instead of an extension?
Bookmarklets are lighter, safer, and more transparent than browser extensions. Extensions require persistent permissions and run in the background. Synapse only activates when you explicitly click it — giving you full control.
What data does Synapse read?
Synapse reads the page's DOM structure, text content, local/session storage metadata, and network request patterns. This is necessary to understand the page context and provide accurate summaries. All processing is done locally in your browser.
Do I need an OpenAI API key?
No. Synapse uses its own backend AI infrastructure during the Beta. You don't need to provide any API keys or sign up for anything.
