Output fit
Anya scans a 40-minute product walkthrough on YouTube, then needs to digest the linked PDF spec sheet and a cited industry article. Same reading session, three source types.
What Reduz produces
- YouTube transcript summary with clickable timestamps that jump the player back to source moments.
- PDF spec sheet summarized from the open Chrome tab without uploading the file anywhere.
- Industry article summarized inline using the same extension and the same provider key.
- All three summaries saved to local storage history, searchable later, exportable to Markdown or DOCX.
- Hosted Free covers the session (3 credits used) or BYOK keeps it direct from your browser to Claude or GPT.
What Eightify produces
- YouTube transcript summary with timestamps — polished, fast.
- No PDF support: Anya needs a second tool for the spec sheet.
- No article support: a third tool or a copy-paste into ChatGPT.
- Summary exists in Eightify's account but not as a portable Markdown or DOCX export.
- Free tier hits a daily cap quickly; paid hosted plan is the workaround.
Privacy and architecture
Vendor-hosted YouTube relay vs direct from your browser multi-source
Eightify routes the YouTube transcript through its own backend on ChatGPT and Claude — the vendor sees the prompt and the source text, and the summary is stored in the Eightify account. Reduz separates the data paths explicitly: when you bring your own AI key, source text goes direct from your browser from your tab to OpenAI, Anthropic, Google Gemini, DeepSeek, or xAI Grok using your own API key, with no Reduz server in the middle and no Reduz account required. In Hosted Free mode, source text goes to the Reduz relay (100 monthly credits, installation identifier for quota only) and then to a hosted AI model. Summary history is stored in a your device on your device; optional encrypted cloud backup is on-device encrypted before upload. Reduz uses click-only permission instead of permission to read every page and ships no analytics or telemetry.
