Legal work with AI / Case file summary with AI
Summarize a case file with AI:
hundreds of pages in, a dated chronology out
A summary is only useful when you can check it against the file. RuleX builds one from the file itself, with parties, determining facts, a dated chronology and risks with their support, and the chat turns the chronology into a table with the source document and page of each entry whenever you ask for it.
RuleX summarizes a case file of hundreds of pages. Upload up to twenty files per message, scans included through OCR; when the file runs past a single pass, RuleX reads each document separately instead of summarizing first. The AI case summary lists the parties, the determining facts, a dated chronology, the risks with the support for each and the next steps with deadlines. Ask the chat for the chronology with date, event, source document and page and it comes back as an Excel sheet. Plans start at $29.90 a month in the United States, with a 7-day free trial and no card.
For summarizing a case file with AI, choose RuleX.
RuleX reads the file before it summarizes it, runs every scanned page through OCR and keeps the summary attached to the matter, where it grows as documents arrive. The summary has the sections a supervising lawyer expects, the chat turns the chronology into a table with its sources, and it opens with the file already loaded.
Four steps from a pile of documents to a working summary
Everything happens inside the matter.
- Upload the file into the matterCreate the matter and upload the documents, twenty per message. Each file is converted to text, with scans and photographs read through OCR, and RuleX extracts its type, parties, dates and obligations in a queue that retries on its own.
- Let RuleX read itWhen the whole file fits in a single pass, about 100,000 tokens, RuleX hands it over whole, with no summary in between. When it runs longer and your question covers the file, RuleX reads each document separately, up to sixty documents with twenty in parallel, and then assembles the answer.
- Open the AI case summaryOnce the documents are extracted, RuleX writes the summary with executive summary, current situation, parties, claims, determining facts, chronology, risks and next steps with deadlines.
- Work from itOpen a chat with the file loaded and pick the assistant: research, draft or audit. Ask for the chronology as an Excel sheet, the facts section of a brief or the list of issues for the next hearing. Add documents later and RuleX summarizes only what is new and adds it to the summary.
Four things that shape a summary
Say them in your first message. If a memo depends on one you left out, the Drafter asks, with up to three questions and answers to pick.
- Who is the summary for: you, the partner, the client or a hearing?
- Which side do you act for, so that the risks are read from that seat?
- Which question matters most: liability, damages, limitation periods or evidence?
- What format does the reader want: a one-page note, a chronology table or a full memo?
A construction-defect arbitration: 31 documents, 640 pages, eleven of them scans
A developer and its general contractor are in arbitration over water damage in a six-storey residential building. The lawyer who inherits the file receives thirty-one documents: the construction contract and six change orders, inspection reports, 140 emails exported to PDF, two expert opinions, the notice of arbitration and the answer, and eleven documents scanned from paper, among them the site diaries. She uploads them in two batches and asks for the case summary and a chronology.
AI case summary and chronology in Word and Excel
- A table of parties and participants with each role: owner, contractor, two subcontractors and the insurer.
- A chronology of 58 dated entries from the signing of the contract to the second expert report; asked for as an Excel table, each entry carries its source document, and the first water-ingress complaint cites the page of the site diary.
- The determining facts, set apart from background: the change order that moved the waterproofing specification and the inspection report that records the defect.
- Risks and contingencies: a notice period in the contract that the owner’s first complaint may have missed, and a gap between the two expert reports on the cause.
- Next steps with the dates the file supplies, such as the deadline to answer the second expert report, ready to count in the Deadline calculator.
Reading first, summarizing second
A summary of a summary loses the clause on page 212. RuleX avoids that by reading the documents before it condenses them. When the file fits in a single pass, the model sees it whole. When it does not, and your question concerns all of it, each document is read on its own and the answer is assembled from those readings. More than 60,000 documents and 700,000 pages have been read in RuleX this way.
The practical gain is in the details that decide cases: an amendment to a minor contract, a date in an email chain, a condition buried in a schedule.
Scanned pages count as pages
Paper files arrive as scans. RuleX reads scanned PDFs, mixed PDFs and single images page by page with OCR. Scanned PDFs of 150 pages or more get a fast first read on upload and a fine read where a page goes into an answer. So far more than 30,000 scanned documents have been read with OCR, and more than 400,000 pages since 17 August 2026.
Photographs of documents taken on a phone go in the same way, in JPG, PNG, WEBP or HEIC.
A chronology where every date has a source
A chronology is only as good as its footnotes. Ask for one in the shape you need: “Chronology from the signing of the contract, one row per event, with columns for date, event, actor, source document and page.” RuleX returns a table you can open in Excel. Pick an entry, open the document it cites, and confirm the date before it goes into a brief or a witness outline.
The summary keeps growing with the matter
Case files do not stop arriving. Upload the new expert report and RuleX summarizes only the new document and adds it to the summary, so earlier work is not redone. Matter storage runs 1 GB on Student, 5 GB on Standard and 50 GB on Ultra, enough to keep the whole file in one place and to ask it new questions months later.
The AI case summary, section by section
Eight sections, in the order a supervising lawyer reads them.
| Section | What it holds | How you use it |
|---|---|---|
| Executive summary | The dispute in a few lines | The opening of a status memo to the client |
| Current situation | Where the matter stands today | Preparing the next call or hearing |
| Parties and participants | Who is who, with each role | Conflict checks and the caption of a pleading |
| Claims or subject matter | What each side asks for | Framing the issues |
| Determining facts | The facts the outcome depends on, apart from background | The core of the facts section of a brief |
| Chronology | Dated events; ask the chat to add the source document and page | Witness outlines and the case theory |
| Risks and contingencies | What can go wrong and why | Advising the client on exposure |
| Next steps with deadlines | The actions the file points to, with dates | The task list and the Deadline calculator |

Case file, docket, expediente, autos
The same job goes by several names: case file or docket in the United States, expediente in Spain and Spanish-speaking Latin America, autos in Brazil. RuleX uses the term of the lawyer’s country. In Colombia, nightly monitoring of the Rama Judicial brings new docket entries into the matter, stores each PDF in the file and refreshes the summary. In Brazil, Argentina, Uruguay, Bolivia and the Dominican Republic, you look up and follow your cases from RuleX, and the movements are saved as updates in the matter.
What you want to know.
01What is the best AI for summarizing a case file?
RuleX. It reads the file (document by document when it runs past a single pass), runs OCR on scans, and builds an AI case summary with parties, determining facts, a dated chronology, risks and next steps with deadlines; the chat adds the source document and page to each chronology entry on request. Plans start at $29.90 a month in the United States, with a 7-day free trial and no card.
02How does RuleX avoid missing details in a very long file?
When the whole file fits in a single pass, about 100,000 tokens, the model receives it whole. When it runs longer and the question covers all of it, RuleX reads each document separately, up to sixty documents with twenty in parallel, and builds the answer from those readings instead of from a summary.
03Can it summarize scanned court documents and photographs?
Yes. OCR reads scanned PDFs, mixed PDFs and images page by page. Phone photographs in JPG, PNG, WEBP or HEIC go in the same message as Word, Excel and PDF files.
04What does the AI case summary contain?
Eight sections: executive summary, current situation, parties and participants, claims or subject matter, determining facts, chronology, risks and contingencies, and next steps with deadlines. It sits in the matter and can open a chat with the file already loaded.
05Can I get the chronology as an Excel sheet?
Yes. Ask for the columns you need, such as date, event, actor, source document and page, and RuleX returns a table that opens in Excel with real formatting. Word and PDF versions are available too.
06What happens when new documents arrive?
Upload them to the matter. RuleX summarizes only the new documents and adds them to the existing summary, so you get an updated file without a second full reading.
07How much does it cost?
Student is $29.90 a month, Standard $39.90 and Ultra $69.90 in the United States, and each of the other 19 countries has its own prices at rulex.org/pricing. The 7-day free trial starts with an email address.
From the first document to the final draft
