About DeeLexy

What DeeLexy is, who it is for, and how it helps with legal questions.

DeeLexy is a legal AI workspace for legal questions that arise at work, in business, and in everyday life. It helps you understand legal requirements, review documents, identify risks, and draft legal text.

DeeLexy brings together legal research, your documents, and the context of your specific question or matter. When an answer draws on sources, you can review them alongside the response.

Legal AIPlatform

The name DeeLexy combines deep analysis and lex, the Latin word for law: AI that works through legal questions in depth.

PlatformBrand

Anyone dealing with legal questions: legal professionals and in-house teams, business owners, developers, marketers, designers, freelancers, and individuals. You don't need a law degree to get started.

A developer might need website terms or guidance on software rights; a marketer might need to understand advertising rules; a designer might want to review intellectual property clauses; and a lawyer might need to examine case law and competing arguments. What matters is the legal question, not your job title.

Who it's forBusiness

General-purpose AI assistants can help with legal questions too. DeeLexy's distinction is its dedicated legal workspace: legal research, document analysis, separate contexts for chats and matters, and sources you can return to when checking a conclusion.

DeeLexy can examine relevant laws and case law, consider dates and applicable versions, connect legal sources with your own materials, and continue work on the same matter. The aim is more than a plausible-sounding answer: it is an answer whose legal basis you can examine.

Why DeeLexySources

No. DeeLexy can help research questions, explain documents, identify risks, draft materials, and test arguments. It does not act as your legal representative or make legally significant decisions on your behalf.

For litigation, high-value transactions, strict filing deadlines, or other high-stakes matters, have an appropriately qualified professional review the key conclusions and documents before you act.

LimitationsLegal professionals

What you can do

Contracts, website terms, advertising, intellectual property, and legal drafting.

Ask about a legal issue, understand a notice or demand, review transaction terms, research laws and case law, assess possible risks, or prepare a document draft.

DeeLexy is useful beyond traditional legal practice: launching a website, advertising a product, working with clients, using third-party content, hiring, or dealing with an everyday dispute. Describe your situation in your own words; you don't need to know the legal terminology or write an elaborate prompt.

Use casesLegal questions

Yes. Upload a contract, schedules, correspondence, invoices, or other relevant files and ask DeeLexy to look for unclear terms, deadlines, obligations, risks, inconsistencies, or changes between drafts.

DeeLexy can relate these documents to the facts of your matter and, where necessary, to legal sources. Tell it what you care about most—for example, termination rights, liability, payment terms, or ownership of intellectual property.

ContractsDocuments

Yes. DeeLexy can help prepare drafts of terms of service, customer terms, payment and refund terms, privacy notices, and other legal text for websites, apps, and digital products.

Describe your product, users, payment flows, data practices, and relevant jurisdiction. Before publishing, check that the documents meet applicable requirements and accurately reflect how your business operates.

Terms of serviceWebsites

Yes. You can explore advertising disclosures and restrictions, permissions to use images or music, content licences, rights in design or software, and how work product is assigned or licensed to a client.

DeeLexy helps identify the legal issues, research applicable rules, and prepare recommendations or draft clauses. The right answer depends on the jurisdiction, relevant facts, contracts, and current requirements.

AdvertisingIntellectual property

Yes. Based on your account and supporting files, DeeLexy can help draft a letter before claim, complaint, response, application, or other legal document, then revise it with you.

Before sending or filing anything, verify the facts, supporting evidence, names and details, deadlines, jurisdiction, and procedural rules. Drafting a document in DeeLexy does not mean it has been filed or sent automatically.

Legal draftingDocuments

Yes. Upload an example and explain what to preserve, such as its structure, tone, format, or sections. DeeLexy can create a new draft for your situation or revise an existing one.

You can also ask it to explain legal language in plain English, make a letter more formal, shorten a document, or adapt the wording for a client, executive, or counterparty while preserving its key meaning.

TemplatesEditing

Yes. DeeLexy can help examine legal arguments, competing positions, exceptions, case law, proposed legislation, and regulatory changes. You can use the findings to prepare an explanation, research memo, or draft legal analysis.

The most recent publication is not always the applicable authority: dates, previous versions of the law, and the circumstances of your matter can all be decisive. Where the available materials do not support a clear conclusion, the response should say so.

Legal researchRegulation

Answers and sources

Legal sources, web research, case law, and checking the basis of an answer.

You can review the documents and legal sources used alongside the answer. Linked materials help you move from a conclusion to a statute, judicial decision, other authority, or your uploaded file and examine it for yourself.

Sources still need interpretation in context: a citation alone does not make a legal conclusion correct. For important decisions, check dates, applicability, and the underlying facts as well.

Verifiable answersSources

DeeLexy helps find and compare laws, guidance and judicial decisions relevant to your question. It can draw on the legal knowledge base, web research and your documents, prioritising official legal sources.

For something that happened in the past, the applicable law may be an earlier version rather than the one in force today. Give the date of the events so DeeLexy takes the right period into account, and check the version through the source link before relying on it.

Our Methodology explains how sources are found and answers are written.

LegislationCase law

Yes. Web search is one of DeeLexy's research tools. It can be used to find current information, official publications, additional legal materials, or facts that need checking.

Search is used when the task calls for external information. DeeLexy compares what it finds with other sources and your materials.

Web searchUp-to-date information

DeeLexy can compare competing positions, investigate which facts and time periods they concern, and explain the roles of general rules, specific exceptions, or differences in case law.

If the available evidence does not reliably resolve the conflict, the answer should identify the uncertainty and material alternatives rather than presenting a disputed issue as settled.

Conflicting sourcesLegal reasoning

Yes. Generative AI can misinterpret a rule, overlook a fact, work from incomplete context, or apply an authority incorrectly. Source visibility helps you spot problems, but it cannot guarantee that every conclusion is correct.

For consequential decisions, clarify the facts, verify important sources, and seek qualified legal advice where appropriate. DeeLexy supports legal analysis; it does not replace professional judgment or responsibility.

AccuracyLimitations

Chats, matters, and documents

Chats, matters, documents, and continuing work in the right context.

A chat is useful for asking a quick question, reviewing text, or starting a discussion without setting up a formal workspace. A matter is a dedicated space for longer-running work on one situation, with related documents, conversations, and a continuing history.

You can start in a regular chat. If the issue grows or you need to keep track of more materials, organising the work as a matter may be more convenient.

ChatsMatters

Yes. You can add contracts, correspondence, invoices, claims, and other files, ask questions about them, and compare related provisions. Documents associated with a matter remain available within that matter's context.

DeeLexy uses materials relevant to the task. This does not mean every stored file is sent in full to the AI for every answer.

FilesDocument analysis

You can include relevant files in the active context and exclude those you don't want influencing subsequent answers—for example, keep an older contract draft on file while analysing only the current version.

Excluding a document from analysis is not the same as deleting it. The file can remain in your chat or matter until you choose to remove it separately.

Context controlsDocuments

Yes. Chats retain their conversation history and related materials, while matters help maintain context across longer projects, including documents, facts, and previous results.

You can return to add new information or files, revisit an earlier conclusion, test another interpretation, or draft the next document without starting the conversation from scratch.

HistoryOngoing work

Privacy and data

Separate work contexts, data protection, and deleting your materials.

No. Chats and matters have separate working contexts. Materials from one situation are not used to analyse another, even when both belong to the same account.

DeeLexy works with information relevant to the current task and lets you control which documents participate in the analysis, reducing the risk of mixing up facts from different matters.

PrivacyData separation

No. Your documents, questions and DeeLexy's answers are not used to train, fine-tune or improve AI models — by us or by our partners. They are processed only to carry out your tasks.

See the Privacy Policy for details.

Your dataAI training

DeeLexy uses separate working contexts, access controls, secure data transmission, and encryption at rest. You can manage your files and remove materials you no longer need.

You can delete a single document without deleting its chat or matter. Deleting a matter affects the workspace and its associated conversations and materials; the interface asks for confirmation before that action.

Reasoning depth

Reasoning depth: Quick, Balanced, and Thorough.

It is the Depth control under the message box: you choose what matters more — a faster answer or a more thorough look at the question. The options are Quick, Balanced and Thorough; Balanced is the default.

You can change the depth before each question. It does not set the length of the answer and does not switch off work with sources.

Reasoning depthSettings

Quick is for relatively clear questions when speed matters. Balanced suits most everyday tasks. Thorough is for questions that benefit from closer examination of complex arguments, exceptions, and alternative interpretations.

These are not three standards of legal correctness. All options retain the same requirements for accuracy and verifiability, and none promises a fixed number of searches, sources, or research steps.

QuickThorough

More extensive work may take longer and use more of your allowance, but consumption reflects the work actually performed—not a fixed charge for selecting a particular depth. A simple question at Thorough depth may not cost much more than the same question at Balanced depth.

All three options are available on every plan. If you're unsure, start with Balanced; choose Quick for a straightforward question or Thorough for a complex or uncertain issue.

Plans and AI usage

Free, Start, Pro, AI usage, and top-ups valid for 12 months.

Only the amount of AI usage. Both plans include everything DeeLexy does — legal sources, documents, chats and matters, and every reasoning depth. Pro includes 4× the monthly AI usage of Start.

Start suits regular work; Pro suits heavy use, when you work through legal questions, review documents and research case law every day.

StartPro

Any AI work uses your allowance: simple tasks use less, complex research and work with documents use more. You are charged for the work actually done, not a fixed price per question or per reasoning depth.

Settings shows what is left as a percentage and as an approximate number of answers. The Terms of Service call this allowance AI Usage.

AI usage

They are estimates from measuring typical tasks, not message limits. How many answers you actually get depends on your questions and documents.

The three numbers — for Quick, Balanced and Thorough depth — describe one shared allowance and don't add up: if you only use Balanced depth, use the Balanced estimate as your guide.

Estimates

Running out of usage does not cut off an answer already in progress. You can ask new questions again when your allowance renews at the start of the next billing period, after you buy a top-up, or after you upgrade from Start to Pro. On Free, choose Start or Pro to keep working.

If a service error stops an answer from being delivered, it doesn't use your allowance.

AllowanceTop-ups

No. Start and Pro usage renews at the start of each paid billing period, and anything unused does not carry over.

Top-up usage is tracked separately: it remains available until used up, for up to 12 months from purchase, and is used after your plan's allowance.

Billing period

Any unused balance stays available after the paid plan ends, until used up or for up to 12 months from purchase.

Top-ups are bought on an active Start or Pro plan and are used after your plan's allowance, soonest-expiring first. A top-up doesn't change your plan or what it includes.

Top-ups12 months

No. The trial allowance is granted once, when you sign up, so you can try DeeLexy on a real task. It doesn't renew and isn't restored.

When you choose Start or Pro, the plan's allowance replaces the trial. Top-ups aren't available on Free.

FreeTrial

Moving from Start to Pro charges the difference and adds the extra allowance prorated for the rest of the paid period; you see the terms before you confirm. Moving to a lower plan or to Free takes effect at the end of the current period.

Top-up usage you bought earlier keeps its own expiry date.
