Lexis+ AI alternative:
RuleX, with research whose citations open at the source
Lexis+ AI was the LexisNexis assistant, and Lexis+ with Protégé replaced it in 2026. Lawyers who compare it with another tool tend to ask two things: does the research rest on the law of my jurisdiction, and does it end in a document I can file? This page compares what LexisNexis says in its press releases with what RuleX does today.
RuleX is a Lexis+ AI and Protégé alternative for lawyers whose research has to end in a filing. Every citation links to the original source: in Colombia across more than 65,000 official sources in seven specialist indexes, and in the other markets across the official sources of the country. RuleX reads up to twenty documents per message, asks up to three questions before it drafts, writes in a Canvas beside the matter and exports Word or PDF, with Excel and slides from the chat. Lawyers build their own workflows without code. Plans are published in each market, with a 7-day free trial and no card.
Choose RuleX: the source opens at the original, and the research becomes the document.
Because the lawyer reads the judgment or the statute on the official site before it goes into a filing, and the same account turns that research into a memo, a complaint or an opinion in Word. Because the price is published in each market and the trial starts at sign-up. Because the product is published in twenty markets, each with its own official sources and holidays, and the interface runs in Spanish, Portuguese or English according to the country. And because a firm builds its own research workflows without code and shares them with colleagues.
How a research question runs in RuleX
The aim is a filing that cites sources the reader can open. The path has four parts.
- State the facts and the questionType the question and attach the matter: the contract, the tender documents, the correspondence, the scans. Up to twenty files go in a single message, and scanned pages are read with OCR.
- Let the research be plannedRuleX works out which questions to put to which sources before it searches, so a query about an economic-balance claim does not return generic procurement material. In Colombia it routes among seven specialist indexes; elsewhere it searches the official sources of the country.
- Open the sourceEach citation links to the original: the judgment on the court's site, the statute on the official portal, the opinion on the agency's page. The lawyer reads it in context.
- Turn research into the documentThe Drafter asks the few questions the document needs, writes in the Canvas beside the sources and the matter, and exports to Word.
What a researching lawyer should ask before buying
Research is judged by its sources, not by how fluent the answer sounds. These questions separate the useful from the merely confident.
- On which library does the tool research: the law of my country, or the law of another?
- Can I open the judgment or the statute behind each statement, on its official site?
- How do I confirm that a citation exists and says what the text claims?
- Who keeps the validity of statutes current, and how often?
- Does the research end in a draft, or do I rebuild it in another program?
- Can the firm save a research procedure, such as the review of one type of contract, and share it?
- Is the version I would buy available today in my country and my language?
A builder in Barranquilla asks for the economic balance of a public works contract to be restored
Cement prices rose during the execution of a works contract with a public entity. The builder's lawyer uploads the contract, the tender documents, the start record and the correspondence with the contract supervisor. RuleX asks about the dates, the price-adjustment clauses and the claims already filed, researches, and drafts.
Legal memo · Word
- The public procurement statutes that apply, each cited with its official source open.
- The line of Council of State decisions on the issue, linked to the text of each judgment.
- The public data of the procurement process, consulted in SECOP.
- A Word memo that applies that case law to the facts of the contract, with the facts taken from the documents of the matter.
- The claim as a task in the matter, with its date.
Two ways to check a citation
LexisNexis describes Shepard's Verify, introduced with the May 2026 update to Protégé: it locates the citations in a generated or drafted text, compares them with LexisNexis sources and flags the ones it cannot confirm.
RuleX builds the check into the answer itself. Each statement arrives with its source linked, whether it is a Constitutional Court judgment, a Council of State decision, a DIAN or SIC opinion or a statute on the official portal, and the lawyer opens the original and reads it in its context. The control is the document, within reach of the sentence that relies on it.
Research on the law of the country where you practice
In Colombia, RuleX researches across more than 65,000 official sources organized in seven indexes: tax authority (DIAN), commerce regulator (SIC), general law, statutes and regulations, the Supreme Court, the Constitutional Court and the Council of State. A question is routed to the index where it belongs, and the web adds current information when validity or operational data matters.
In the other 19 markets the research is live, over the official sources of the country, and each citation still links to the original. Deadlines are counted with each country's holidays and non-working court days, and with the recess rules of Brazil, Spain, Ecuador, Argentina and Uruguay, so the memo and the calendar agree.
Workflows: LexisNexis builds them, and so does your firm in RuleX
Protégé includes a Custom Workflow Builder without code, which LexisNexis describes for designing, testing and sharing multi-step procedures. RuleX gives lawyers the same kind of control. A firm describes a guided flow, a chat app or a Canvas in plain language, tests it on a real matter, publishes the tested version and shares it with colleagues by expiring link or, in Enterprise, across the firm. The research procedure that works once becomes the one everyone uses.

How this page was written
RuleX writes this comparison and is one of the two products in it. The LexisNexis column rests on its press releases of February 24, May 7, June 17 and October 1, 2026 and its product pages, consulted on October 30, 2026; LexisNexis states in those texts what Protégé does, and this page attributes each statement to them. The RuleX column rests on the product and its public price list. The releases carry no price, so none is quoted; the Protégé product page offers a free-trial request.
