Glasp YouTube Summary is a popular YouTube-only summarizer. Its meaningful strength is the no-signup default for the basic flow. Many readers come looking for an alternative when their workflow includes PDFs, articles, or selected text alongside YouTube. Reduz preserves the no-signup ease and extends to PDFs, articles, webpages, transcripts, and selected text in one extension. It adds local history that survives reinstalls, your AI requests going directly from your browser when you bring your own AI key (OpenAI, Anthropic, Google Gemini, DeepSeek, xAI), and 100 free hosted credits without a card.
Where Reduz fits
Use Reduz when no-signup convenience matters but your workflow also includes PDFs, articles, or selected text, and when you want your AI requests going directly from your browser to your provider.
Reduz is a privacy-leaning alternative for readers who want their summary history on their own device, the option to use their own AI provider key, and the same in-tab workflow on YouTube videos, PDFs, articles, and webpages — not just one source type.

The case for Reduz over Glasp YouTube Summary
Reduz is the right fit when your reading workflow spans multiple source types and you want the data path to be predictable. It runs from the active Chrome tab with click-only permission — the extension can read a page only when you click it. When you bring your own AI key, source text goes directly from your browser to your selected AI provider, with no Reduz server in between. Summary history stays on your device, with optional encrypted backup if you want a copy off-device.
