RuleX is legal AI software for U.S. attorneys, law students and legal teams. Research federal and state law with primary sources, analyze matter documents, draft in Word, build reusable agents and produce Word, PDF, Excel and presentations. Includes matter management, document storage, hearing transcription and electronic signatures, with USD subscriptions and a seven-day trial.

**Electronic signatures.** Electronic signatures and records receive legal effect under E-SIGN, subject to the transaction’s statutory requirements. RuleX supports document signing with email verification and document sealing. Applicable legislation: E-SIGN Act, 15 U.S.C. § 7001 ([source](https://www.govinfo.gov/content/pkg/USCODE-2024-title15/html/USCODE-2024-title15-chap96-subchapI-sec7001.htm)).

## 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.

## A clear price. A complete workspace.

Choose the capacity that fits your practice. All three plans include the same legal AI workspace. Pay monthly, every six months or annually in U.S. dollars through Paddle. Review the applicable taxes and renewal total in checkout.

## Example: build a federal motion research package.

1. **Bring the record.** Add the complaint, relevant agreement, correspondence and court order. State the district, claims, procedural posture and requested motion.

2. **Find the legal elements.** Ask RuleX to identify the issues, relevant procedural rule and controlling authorities. Open the primary sources and examine how their facts relate to yours.

3. **Develop the argument.** Answer the follow-up questions, distinguish contested facts and ask for a memorandum with the strongest counterargument addressed.

4. **Deliver and continue.** Review and export Word. Save the chronology and a deadline task in the matter so the next revision starts with the same context.
