Free AI summarizer vs ChatGPT

Our free summarizer does one job: paste an article URL or upload a document and get the key points in seconds — no account, no prompt. ChatGPT is a general-purpose assistant that can summarize too, plus almost everything else. Here's an honest look at when the one-job tool is enough — and when it isn't.

What you actually get

A one-shot summary box, or a do-everything assistant.

The free Sidenote summarizer

Paste an article URL or upload a PDF, Word, PowerPoint, text, Markdown or RTF file (up to 4 MB) and get the key points in seconds. No account, no card, nothing stored. Being free, it's rate-limited by IP with a small daily cap, and very long documents are summarized from their first portion.

ChatGPT

A general-purpose assistant: writing, brainstorming, coding, image generation, voice and live web browsing, with native mobile and desktop apps. To summarize a document you paste the text in or upload the file to a chat, then ask — and you can keep asking follow-ups. Free tier, paid plans above it.

The short answer

When to use which.

Use the free summarizer when…

You have one article or document and just want the key points, fast. No account to make, no prompt to phrase, nothing stored afterwards. It's deliberately one-shot: paste, read, done.

Use ChatGPT when…

You want to interrogate the text, ask follow-ups, rewrite the summary in a different tone, or carry on into writing, brainstorming and coding. For anything past a quick summary, ChatGPT is the stronger tool — ours is a single-purpose box on purpose.

Want summaries with receipts? The Sidenote extension reads the page you already have open and cites the exact passage behind every answer — see Sidenote vs ChatGPT or head back to the free AI summarizer.

A web article or any public page by URL, or an uploaded PDF, Word (DOCX), PowerPoint (PPTX), plain text, Markdown or RTF file up to 4 MB. Scanned PDFs have no text layer, so they need OCR first — the free tool can't do that, but Sidenote can once you sign up.
