AI text summarizer — long text to key points

Paste an article, report or transcript and get a faithful summary in one sentence, a few bullets or a short paragraph. This is a bring-your-own-key AI tool: it works with your Anthropic (Claude) or OpenAI (GPT) API key, which is stored only in this browser and never sent to us to keep. Your text goes to your chosen provider through our server, which never logs or stores your key or your text. It is free — you pay the provider directly for what you use.

How to use it

  1. Add your Anthropic or OpenAI API key in the key bar (it is saved only in this browser).
  2. Paste your text and pick any options.
  3. Press the button — the result comes back from your chosen AI. Copy or Download it.

FAQ

How do I summarise text with AI?

Paste the text, choose a length, add your key and press Summarise. The AI returns a summary that keeps the key points and the original meaning — it is told not to add facts that are not in your text.

Is my text kept private?

Your API key lives only in this browser's local storage. Each request sends your text and key to your chosen AI provider through our server, which never logs or stores either. We keep no copy.

Can it summarise very long documents?

It handles up to about 20,000 characters per request. For a whole book, summarise it in sections and then summarise the summaries.

Where do I get an API key?

From your provider: Anthropic (console.anthropic.com) for Claude, or OpenAI (platform.openai.com) for GPT. Paste it into the key bar once and it is remembered on this device until you clear it.

Does it cost anything?

The tool is free. You pay your AI provider directly for the tokens each request uses — usually a fraction of a cent for short text.

Limits

Summaries reflect what your text says; the AI is instructed not to invent facts, but always sanity-check important figures against the source. Unlike our offline tools, this one calls a cloud AI, so it needs a connection and your own key.
