WebToSpark frequently asked questions
Direct answers about installation, completeness, local data and planned paid features.
Does it capture an entire thread or feed?
Only content currently present in the loaded DOM. Ordinary export does not scroll, paginate or expand replies. Virtualized content can be missing.
Do I need Node.js?
No for ordinary exports. Only the optional macOS Native Host requires Node.js 18 or newer.
Are Markdown, JSON and CSV free?
Yes. Free also includes previews, saved history and duplicate reminders, with 50 source pages per UTC calendar month and five tabs per job.
Can I purchase Pro today?
Checkout and account services are not connected. USD 4.99 per month and USD 29.99 per year are planned prices, not an active offer. Lifetime sales are deferred.
Does it download images or videos?
No. It exports media source URLs. Expiring or signed links may stop working later.
Does clearing cache reset history?
No. History and usage are stored separately. Clearing all extension data or reinstalling can reset local records.
Are research packets an AI service?
No. Pro packets assemble sources and prompts locally. The separate experimental Research Agent is off by default, requires the Native Host and remains deferred as a finished product.
Is everything network-free?
Extraction, cache and ordinary export are local. Opening a collection workspace makes normal website requests. Experimental scrolling can also trigger website requests, and optional configured AI transport can share selected content with a provider. See the privacy page.
