AI Text Summarizer
Summarize long English articles, reports and emails with the DistilBART AI model running privately in your browser. Short, medium or long summaries — no upload, no sign-up.
🔒 Runs entirely in your browser — nothing is uploadedAbstractive summaries generated on your device
This summarizer uses DistilBART CNN 6-6, a compact version of the BART sequence-to-sequence model that was fine-tuned to write news-style summaries. It is an abstractive model: instead of simply picking important sentences, it reads the whole passage and writes new, shorter sentences that capture the main points. The model runs with WebAssembly in a background Web Worker, so the page stays responsive, and your text is never sent to a server. The weights are downloaded from Hugging Face once and then kept in your browser cache for future visits.
That makes it safe for internal reports, research drafts, meeting notes and other documents you would not want to paste into an online AI service. There is no account, no daily limit and nothing is stored.
How long documents are handled
Transformer models can only read a limited number of tokens at once — about 1,024 for BART, roughly 600 to 700 English words. For longer input, the tool splits your text at sentence boundaries into sections of about 600 words and summarises each one. The section summaries are merged, duplicate sentences are removed and, for short and medium summaries, the merged text is summarised once more to produce a compact result. Long summaries keep one paragraph per section, which works well for reports with several topics.
Tips for better summaries
The model performs best on well-structured prose such as news articles, blog posts and reports. Remove navigation text, tables and reference lists before pasting. Choose short for a one- or two-sentence gist, medium for a paragraph and long when you need more detail. Like every AI summarizer, it can occasionally drop a key point or misstate a number, so check important facts against the original.
