AI document summarisation has become genuinely useful. Not the early-generation kind that would produce a vague paragraph that could have been written about anything — the kind that actually reads the structure of your document and pulls out the specific claims, decisions, and numbers that matter.
Filero's summarise tool is built on Groq's Llama 3.3 70B model, which is fast and accurate enough to handle real-world documents: contracts, research papers, meeting notes, financial reports, policy documents. You upload the file, and within seconds you have a focused summary of what it actually says.
How to summarise a document for free
Open Filero's free AI summarise tool and follow these steps:
- Upload your document (PDF, Word .docx, or plain text) or paste the text directly into the input field.
- Click Summarise.
- The AI reads the full document and returns a concise, structured summary.
- Copy the result or keep reading for the parts you want to explore further.
No account, no sign-up, and no file is stored after processing. The tool works on any device.
What kinds of documents does it work on?
Reports and whitepapers. Industry reports are often 30 to 80 pages of context surrounding five or six actual findings. AI summarisation pulls out those findings directly, along with the key figures and recommendations.
Contracts and legal documents.Legal language is dense by design. A summary will not replace a lawyer's review for high-stakes decisions, but it will tell you what the document covers, what the main obligations are, and where the unusual clauses sit — so you can focus your attention on the right sections.
Research papers. Academic papers follow a predictable structure: abstract, introduction, methods, results, discussion. AI summarisation is particularly good at scientific content because it can identify the research question, the methodology, and the conclusions without needing to read every line of the methods section.
Meeting notes and transcripts. Paste in a long set of meeting notes or a transcript and get back a list of decisions made, action items assigned, and key points raised.
Long emails and threads. Paste in a long email thread and get a clear summary of where the conversation landed and what was agreed.
How accurate is AI summarisation?
For factual documents with clear structure — reports, papers, legal agreements — accuracy is high. The model identifies the main claims and key figures without distorting them.
Where AI summarisation is weaker: documents that rely heavily on tables and charts (the numbers are there, but the visual context is not), documents where tone and nuance matter (literary analysis, sensitive HR correspondence), and documents in languages other than English (accuracy drops, though it still works reasonably well).
A good rule of thumb: use the summary to orient yourself, then read the sections that matter in full. The value is in getting to the right sections faster — not in replacing reading entirely.
Other AI tools on Filero
If you need to do more than summarise, Filero has three other AI-powered tools:
- Grammar Check — reviews and corrects grammar, spelling, and punctuation.
- Rewrite Text — changes the tone of any text to professional, casual, formal, or persuasive.
- Translate Text — translates content into more than 20 languages.
Frequently asked questions
Is my document kept private?
Your document is sent to the AI model for processing, but it is not stored by Filero after the summary is returned. Filero does not index, train on, or share your uploaded content.
How long can the document be?
The tool handles documents up to 8,000 characters of extracted text. For very long documents, you can paste in the most relevant sections or use the tool on individual chapters.
Can it summarise a scanned PDF?
Scanned PDFs are images, so the tool cannot read the text directly from them. Convert a scanned PDF to searchable text first using the PDF to Word tool (which runs OCR automatically), then paste the extracted text into the summarise tool.
Does it work in languages other than English?
Yes, the underlying model supports many languages, though its accuracy is strongest in English. For non-English documents, the summary will generally capture the main points but may miss subtleties in phrasing.
