Noiz vs Reduz: Free Web Tools or Extension-First Summaries

Noiz is a free web-tool directory covering YouTube, PDF, article, webpage, book, document, and research-paper summarization. It leans into transparent retention copy ("files are deleted after summarizing") and works without an extension install. Reduz is a focused Chrome extension that summarizes the source you already have open — no upload step, no separate web tool per source type. Reduz adds BYOK across five providers, 100 monthly hosted credits, and local storage history. Pick by whether you want a no-install web utility or a daily-use extension workflow.

Privacy and architecture

Task-specific web tools vs active-tab extension with BYOK

Noiz makes transparent retention a marketing point ("files are deleted after summarizing"), which is a real privacy improvement over upload-and-keep services like ChatPDF or Adobe AI. The trade is workflow ergonomics: each source type is a separate web page, the file has to be uploaded or the URL pasted every time, and there's no persistent history of past summaries to revisit. Reduz keeps the source at the center: the extension reads PDFs, articles, and YouTube transcripts from the Chrome tab where they already live without uploading anything. When you bring your own AI key, source text goes direct from your browser to the AI provider you chose with your own API key — no Reduz server in the middle. Hosted Free uses the Reduz relay (100 monthly credits, installation identifier for quota only, no card). Summary history is stored in on your device, optional zero-knowledge encrypted cloud backup is on-device encrypted before upload. click-only permission, no analytics, no telemetry.

Frequently asked questions

Is Noiz broader than Reduz?

Noiz publishes more individual AI tools across more content types (YouTube, PDF, article, webpage, book, document, research paper, image, text). Reduz is narrower by design — one extension covering YouTube, PDFs, articles, webpages, transcripts, and selected text from the Chrome tab where the source lives.

Why use Reduz instead of a free web tool?

Three reasons: (1) no upload step — the extension reads sources from the Chrome tab; (2) BYOK across five providers so source text goes direct from your browser to your chosen provider; (3) local storage history so summaries survive sessions and can be searched and exported later. If those don't matter, Noiz's free web tools work fine.

Does Reduz handle PDFs without uploading like Noiz claims to delete uploads?

Reduz reads the PDF from the Chrome tab where you have it open — the file is never uploaded to Reduz. Noiz uploads the file and then deletes it after the summary is generated. Both are real privacy improvements over services that retain uploads; Reduz skips the upload step entirely.

Can I bring my own AI key with Reduz?

Yes — Reduz bring your own AI key supports OpenAI, Anthropic Claude, Google Gemini, DeepSeek, and xAI Grok with your own API key. The key stays in Chrome extension storage on your device and requests go direct from your browser to the provider. Noiz is hosted-only with no BYOK option.

Is Reduz free?

Yes. Reduz includes 100 free credits a month. Using your own AI key removes the credit limit.

Do I need an account?

Not when you use your own AI key. An account is only needed for free credits, paid plans, or cloud backup.

Where is my data stored?

Summary history is stored in your browser. Cloud backup is opt-in and encrypted on your device before upload.

Which AI providers does Reduz support?

Reduz supports OpenAI, Anthropic Claude, Google Gemini, DeepSeek, and xAI Grok. You can also use free credits without setting up an AI account.
