AI Summarizer

Summarize articles, documents, and notes with Claude Haiku 4.5. Short, medium, or detailed bullets. Free, no signup.

AI Summarizer turns long articles, research papers, meeting transcripts, or technical docs into a digestible summary. Paste your text, pick the length, get an answer in 2-5 seconds. Powered by Anthropic's Claude Haiku 4.5 — the same model used by businesses for production AI workflows.

Pickrack's summarizer is task-focused, not chat-style: there's no prompt to design, no "please summarize" nudge, no upselling to Pro. You paste text, you get a summary that matches the length you asked for. Output preserves the language of the input — Vietnamese in, Vietnamese out.

Free with a generous daily quota (10 requests per IP per day). For higher-volume use, run Claude API directly with your own key — Pickrack uses no proprietary tricks.

Key features

• Three length modes — Short (2-3 sentences for tweet-length sharing), Medium (4-6 sentences for an exec brief), Long (8-12 bullet points for note-taking).
• Multilingual — Auto-detects language and summarizes in the same language. Tested with English, Vietnamese, Spanish, French, German, Chinese, Japanese.
• Privacy-respecting — Your text is sent to Anthropic's API, processed, and the response is returned. Anthropic does not use API inputs for training. Pickrack stores nothing.
• Fact-preserving — Haiku 4.5 with temperature=0.2 keeps the summary factual to the source. No fabricated numbers, no opinions added.
• No signup, no watermark — Just paste and click. Daily quota of 10/IP — sustainable for casual use without API key setup.
