# Spellbook alternative: contract review with the whole deal behind it

*Alejandro Cárdenas · October 31, 2026*

RuleX is a Spellbook alternative for lawyers who want a contract reviewed alongside its annexes, scanned letters of intent and negotiation emails (up to twenty files per message). It flags risks clause by clause, proposes replacement wording in a Canvas and delivers Word or PDF, with Excel from the chat. The same account covers research with sources that open, litigation drafting, matters with deadlines, e-signature and hearing transcription in 20 countries. Prices are published in each country, with a 7-day free trial with no card.

Spellbook puts contract AI inside Microsoft Word: it redlines, drafts, compares against market terms and runs playbooks while you stay in the document. RuleX starts one step earlier and runs one step later. It reads the deal behind the contract, and it carries the work into the dispute when the contract breaks. This page compares the two on criteria you can check.

## For contract work that has a deal behind it, choose RuleX.

Choose RuleX because it reads the agreement together with the price annex, the letter of intent and the email thread, asks only what the review needs, proposes the replacement wording and exports it to Word. It keeps going when a contract becomes a stack of agreements to compare or a dispute to litigate. The prices are published in each country, the trial lasts 7 days without a card, and one account holds research, drafting, matters, signature and transcription.

## How a contract review runs in RuleX

Four moves, from the first upload to the Word file you send across the table.

1. **Drop the whole deal into one matter.** Upload up to twenty files in a single message: the draft in Word, the price annex in Excel, the letter of intent as a scan, the email thread as PDF. Scans are read with OCR. A file that fits is handed over whole; when the file is long, RuleX reads each document separately so no detail is lost, up to sixty documents with twenty in parallel.
2. **Answer up to three questions.** Before it drafts, RuleX asks only what is essential, with selectable answers: which party you act for, which risks the client will not carry, which terms are not negotiable. Secondary gaps stay as [BRACKETS] in the text for you to fill.
3. **Read every clause against its evidence.** Each flagged clause arrives with the reason and the document it was checked against: the annex, the letter of intent, the email. To ask the same questions of a stack of agreements, Table Review puts one contract in each row and one question in each column, up to twenty-five contracts and twenty questions per run, with the evidence inside each cell.
4. **Redraft and export.** Replacement wording is written in the Canvas, beside the case file, and exports to Word with native heading styles, lists and page numbers, or to PDF. Open points become dated tasks in the matter.

## Questions to put to any contract AI vendor

A contract tool is judged on your agreement, not on the one in the demo. These questions separate the vendors in an afternoon.

- Does the review read the annexes, the letter of intent and the emails, or only the text open on the screen?
- Can I ask the same four questions of a whole stack of agreements and see the evidence behind every answer?
- Where is the price, in my currency, and what does the trial ask of me before it starts?
- Which languages and which countries' law does the review work with, and how are the sources shown?
- Can my firm's review rules become a workflow that every lawyer runs the same way?
- When the contract is breached, do I stay in the same tool for the demand letter, the complaint and the deadlines?
- Where do the files live, who in the firm can open them, and what does the vendor publish about training?

## An exclusive distribution agreement, checked against its own history

A Colombian food exporter receives a master distribution agreement from its Mexican distributor, exclusive for Mexico, Colombia and Peru. The associate uploads five items in one message: the draft in Word, the price annex in Excel, the scanned letter of intent, the 2023 agreement it replaces and a 31-message email thread exported to PDF. RuleX asks three questions with selectable answers: which party the firm represents, which liability the client refuses to carry, and whether exclusivity is negotiable. Then it reads everything, scan included.

- A clause-by-clause risk memo: the five-year exclusivity in clause 4.2 against the three years in the letter of intent, with both passages cited.
- Replacement wording for the three clauses the client cares about, termination for convenience, the liability cap and exclusivity, written in the Canvas.
- A check that every unit price in the Excel annex matches the figures agreed in the email of April 12.
- A Table Review of the client's other eleven distribution agreements: one row per contract, one column per question, evidence in each cell, exported to Excel.
- A Word file with the redraft and a two-paragraph note to the client; open points saved as tasks with a date in the matter.

## How this comparison was made

RuleX publishes this page and competes with Spellbook, so the method is on the table. Everything said about Spellbook comes from its own site (the home page, the pricing page, the Word page and the Ask page) and from press coverage, checked on October 30, 2026, with the links listed below. Everything said about RuleX comes from the product and from rulex.org/pricing. Prices appear where the vendor publishes them.

The figures Spellbook gives for itself, more than 140 languages, more than a thousand sources from more than eighty countries and more than 5,000 legal teams, are Spellbook's own and are attributed to it wherever they appear.

## A contract rarely arrives alone

An exclusivity clause reads differently once you have the letter of intent that came before it, and a penalty is negotiated differently when the emails show who asked for it. RuleX opens every attachment as its own document and keeps the context across all of them, so the review reads the business behind the paragraph.

When the contract is breached, the work continues in the same matter. The same files feed the demand letter or the complaint, the chronology and the theory of the case. Deadlines are counted with the holidays and non-business court days of the country, and the signature closes the loop: each signer receives a link and a six-digit one-time code by email, and the sealed PDF carries a certificate with a SHA-256 fingerprint that anyone can verify on RuleX's public verification page, linked from the certificate.

## Your firm's review rules, built once and shared

A playbook is how a review applies the client's own positions. In RuleX those positions become an agent or a workflow that the firm builds by describing it in plain language, without code: the clauses that are always reviewed, the fallbacks that are acceptable and the shape of the report. You test it on a real matter, publish it, and share it with colleagues by expiring link or, in an Enterprise organization, under "Your firm", so every lawyer reviews to the same standard.

Table Review, which runs up to twenty-five documents and twenty questions at a time, is available in every country. In Colombia, nine more official Apps are built for Colombian law, including contract review, document comparison and due diligence.

## Each country's language and law

The interface runs in Spanish in 18 countries, in Portuguese in Brazil and in English in the United States. In Colombia, research runs on more than 65,000 official sources across 7 specialized indexes (tax authority DIAN, the competition and consumer authority SIC, statutes, the Supreme Court, the Constitutional Court, the Council of State and general law), with every answer linked to the original. In the other 19 countries, RuleX researches the official sources of that country and delivers each citation with its link.

A distribution or supply clause sits under different statutes in each country: the Código de Comercio in Colombia, the Código de Comercio and the state civil codes in Mexico, the Código Civil in Peru and in Brazil. RuleX reviews with the vocabulary of the country where the contract is signed and drafts the replacement wording in the register its courts expect.

## A published price in each country and a trial that starts with an email

RuleX publishes three plans in every market. In the United States: Student $29.90, Standard $39.90 and Ultra $69.90 per month. In Colombia: COP 30,000, 40,000 and 70,000 pesos per month. In Spain: EUR 24.90, EUR 32.90 and EUR 57.90. In Mexico: MXN 189, 249 and 439. The trial lasts 7 days and starts with an email address. Enterprise, with client records, team roles and billing statements, is designed with the firm.

More than 4,000 professionals already work in RuleX, and the Drafter has produced more than 4,000 documents and 8 million words.
