Put the workspace to work.
Start with the matter in front of you.
Practical guides and free tools for researching authority, reviewing citations and turning your matter into legal work product.
Tomorrow’s brief starts with today’s file.
The chronology is in the emails. The clause is in the agreement. The fact you need is buried in an exhibit. RuleX brings those documents into the assignment so the research and the draft start from the record.
Ask for the next concrete deliverable: a motion outline, a supported memorandum, a contract risk table or a client letter. The useful result is work product you can open, review and edit.
The matter stays connected from intake to delivery.
01
Create the matter
Record the client, governing state, forum, relevant dates and objective. Add the documents and keep tasks and notes alongside the file.
02
Research the precise issue
Ask for primary authority for the selected jurisdiction. Review the statute or opinion through its source link and connect it to the record facts.
03
Answer the drafting questions
RuleX asks for facts that change the document: the relief, disputed issues, procedural posture and missing evidence. Supply the answers before writing the final version.
04
Open the work product
Draft in the workspace, revise the reasoning and download Word or another requested format. Keep the supporting documents attached to the matter for the next assignment.
Read the file. Ask the right questions. Write the document.
A case file with memory
Upload PDFs, Word documents, spreadsheets, images and scanned records. OCR and document analysis help turn the material into facts, chronology and questions for counsel.
Drafting with the record in view
Work on the memorandum, complaint, response or agreement in the drafting workspace. Use your own instructions and source material to shape the structure and argument.
Agents you can use again
Build your own workflow for recurring review, chronology or due diligence. Set the instructions once and apply them to the next matter.
Hearings and meetings become usable text
Transcribe the recording, organize the speakers and connect the transcript to the matter. Reuse it for the chronology, notes or the next draft.
The deliverable is a file you can work with.
| Assignment | Work product | Use it for |
|---|---|---|
| Research a jurisdiction-specific issue | Word memorandum with source links | Reviewing the argument and preparing client advice |
| Compare an agreement and a proposed revision | Risk matrix or comparison table | Negotiating language and tracking open issues |
| Reconstruct the record | Chronology and document references | Preparing a deposition or a hearing |
| Present the matter | PDF or slides | Sharing a reviewed position with your team |
The state, the forum and the authority matter.
A California contract dispute and a federal motion in New York call for different questions. Tell RuleX where the matter belongs. Its U.S. legal method distinguishes governing substantive law, procedural rules, local rules and the force of precedent.
Research starts with primary sources: official legislation, regulations, court opinions and competent agencies. Citations link the argument to the authority you can open. Your assignment supplies the jurisdiction and facts; the draft connects them.
