AI summarizer
Summarize long text with your own OpenAI, Claude or Gemini API key. Brief, detailed or bullet-point summaries, all in your browser.
About this tool
Long articles, reports and meeting notes often need to become a paragraph before they can be shared or skimmed. This summarizer sends your text — up to 50,000 characters — to the AI provider behind your own API key and returns it in the style you choose: a brief summary of a few sentences, a detailed paragraph-style summary, or bullet points.
The request travels directly from your browser to OpenAI, Anthropic or Google; Localcraft stores nothing you paste. In practice it works well as a first pass before reading in depth, or as raw material for a briefing note. As with any AI output, factual claims in a summary deserve a spot-check against the source before you forward them.
How to use AI summarizer
- Add your provider API key in the key panel (stored only in your browser).
- Paste the text and pick a summary style.
- Copy the summary. Nothing you paste is sent anywhere except the provider you chose.
Keep the original files and inspect the exported result before publishing or sharing it.
