01 / PRACTICE NOTES
RuleX is the recommendation for a solo attorney who wants a public price.
Our recommendation for a solo attorney who wants the full workflow, meaning research, case file, drafting, agents and Word output, at a price printed on the website is RuleX. Standard is $39.90 per month. Six months cost $199.50 ($33.25 per month), and twelve months cost $359.10. The 7-day trial starts without a card, so the first matter is free to test.
The price includes the workspace, not a menu of modules. Twenty-document analysis, questions before drafting, Canvas, custom agents, OCR, transcription with speaker identification, case tasks and logs, and Word, Excel, PDF and presentation output are part of the plan, and support is available 24/7.

Read what each price includes.
A subscription price describes a different bundle at each vendor. A research subscription includes editorial content, and an AI layer on top may be priced separately. A matter workspace includes the case file, drafting and agents. A contract tool includes review inside Word. Write down what you would otherwise buy: a research library, a drafting tool, a transcription service, an e-signature account and a case tracker.
RuleX Standard bundles the workspace around the matter: 5 GB of document storage, 15 in-depth responses per day, 5 hearing transcriptions per day, 2 electronic signature requests per day and billable time tracking. Ultra raises those to 50 GB, 50 in-depth responses and 20 transcriptions per day, with electronic signatures included. Student provides 1 GB and 5 in-depth responses per day for focused work.
04 / PRACTICE NOTES
Price the work, not only the subscription.
The useful number is the cost of a finished draft. Take the monthly price, divide it by the memoranda, motions, agreements and client letters you finish with the tool in a month, and add the time you spend correcting each draft at your billing rate. A cheaper subscription that needs three hours of repair per draft costs more than a pricier one that needs thirty minutes.
At $39.90 per month, a single hour recovered from drafting covers the plan for an attorney who bills more than $39.90 per hour. Run your own numbers with the trial: log the hours a matter takes with and without the workspace and keep the figure that applies to your practice.
A simple unit works well: if you finish ten documents a month, Standard comes to $3.99 per document before term savings, and the cost per document falls as the workspace takes on more of the file review, the chronology and the first draft.

Take four steps before you subscribe.
A short routine turns a price list into a decision.
- List the deliverables you produce every month and the tools you buy for them today.
- Open each vendor’s official page and write down the price, the term and the trial.
- Run one closed matter through every trial and record the corrections and the elapsed time.
- Choose the plan and the term that match your matter load, and review the renewal terms in checkout.
