Type your question in the box at the bottom and press Enter or the arrow button. To start a new line without sending, press Shift and Enter together. The box tells you who you are talking to: Ask the case file… with a case file open, Ask about this matter… with a matter in front of you.
Ask as you would ask a colleague who has read the case file: “What did the insurer offer and why did it reject the claim?”, “When was the judgment served?”, “Who signed the expert report?”. You can also ask about what JUDLEX already has on record: “Who are the parties?”, “What is still outstanding in this matter?”.
When you open a case file
If guidance is switched on, when you open a case file the panel tells you where things stand (how many exhibits it has, how many facts and parties are still to be confirmed, whether anything does not add up) and suggests questions to start with, such as Sum up where the matter stands or Who is who here?. Click one and it is sent. This costs nothing: it comes from what JUDLEX already knows, without asking the artificial intelligence.
You switch guidance off in the panel options: Panel options.
Before you ask: the literal search
With a case file open, once you have typed a few letters, the number of literal matches in the case file's pages appears above the box, labelled local search, no cost. Click it to expand them, each with its exhibit, its folio, its page and the snippet of text where it appears.
It lets you find a word, a name or a figure without spending anything, and see whether a question is worth asking.
The answer
An answer can hold up to three kinds of text, and each one looks different:
Plain text, with no frame: what JUDLEX has found in the papers, set out clearly. Each part answers for its own citations: it is only shown if at least one of them has been checked on its page, and any date it mentions has to be on those pages.
In blue, labelled “Recorded in JUDLEX”: what comes not from a page but from what the application has on record (a confirmed party, a deadline in the diary, a paper on the list). Underneath it carries the reference of each record. JUDLEX checks that those records exist and that the dates it mentions are in them. If it contains a date that could not be checked, the label adds dates not verified.
In amber, labelled “From the model · not checked against the case file”: anything that comes from neither a paper nor a record. It is professional guidance from the artificial intelligence; it can be wrong and you should check it.
Below the text:
Where this comes from: one card per citation, with the exhibit, the folio, the page, the document title and the exact sentence. For a matter with no case file, the card gives the paper and the page. Clicking the card opens the document at that page.
How many citations have been checked against their page. JUDLEX looks for each quoted sentence on the page it names; if it is not there, the citation is discarded.
What was removed, if anything fell away: a folded line saying how many items were removed because they could not be verified. Click it to see each one, with its snippet of text and the reason. If part of the answer is removed, a sentence saying so takes its place; if nothing is left standing, the answer says it is not in the case file.
If some pages of the case file have not been read yet, the answer warns that it only covers what has been read: Read pages and find dates.
While it answers
While it prepares the answer, the panel says Reading the case file… or Reading the matter's papers…, and the text appears as it arrives. If you switch to another window in the meantime, JUDLEX tells you when the answer is ready, according to what you have chosen in Notifications.
Sometimes, before answering, JUDLEX asks you a question with options: Before I answer. Pick one, or type your answer in your own words and press Enter.
When it does not find it at first
JUDLEX does not settle for its first answer if it does not fully answer. Before showing it, it checks that what it says about the papers is really on their pages and whether something is missing; if so, it tries another way —searching with other words, going through the index, reading the whole paper— and the panel says so with a step («Not settling for «not found»: trying another way»). It does this a few times at most, with a spending cap per question.
If in the end it does not find it, it tells you what the papers do say and what is missing, and below, folded, What I looked at: the ways it tried.
Searching the web
Some things no paper can say: whether a rule is still in force, how a procedure is done or what general deadline the law sets. With Search the web when the papers are not enough on (in the chat menu, next to Automatic steps), JUDLEX can look it up on the web with your AI provider's own tool (Anthropic or OpenAI). With other providers, including any you add yourself, it is not available.
Only the search goes out, never your papers or the conversation, and before it goes JUDLEX removes anything with names, case or policy numbers, plates, ID numbers or any data from your papers. If it cannot be cleaned, it is not sent and you are told.
The panel announces it first («Searching the web: «…» · this goes out to the internet») and afterwards says what the search engine actually searched.
What comes from the web is shown apart, marked From the web, with its sources, which open in the browser. If it quotes a page that did not come back from the search, or gives a figure that is not in it, it is removed.
Each search is charged to your key and shows in spending as Buscar en internet desde el chat.
With it off, JUDLEX answers only with your papers, what is recorded and what it knows.
A long conversation
JUDLEX sends what has already been said with every question, so that “and the second one?” makes sense. How much fits depends on the model you use: when the conversation reaches about three quarters of what it accepts, JUDLEX summarises the oldest part until it is down to half. While it does so, the panel says Summarising the earlier conversation so it fits, and then marks it with an amber line: Everything above travels summarised. Click it to read the full summary.
The summary keeps the figures, dates and names that were mentioned, each one marked unverified. It is written by the artificial intelligence, so it is not a source: in a matter or a case file, anything JUDLEX states still needs its citation in a paper.
Documents you have brought into the conversation are also summarised once they no longer fit, starting with the oldest; the last one you brought and any draft you have open always go in full. Their card says summarised. If you ask about one of them, JUDLEX reads it in full again.
Each summary is one more call and is paid for like the others. If it cannot be made, the panel says so and tries again with the next question.
Start again
The pencil button in the panel header opens a blank conversation. The previous one is not lost: it stays in the history. See The history.
The buttons on each message
Under each message there are a few small buttons:
Copy, on your messages and on the answers: it copies the text as you see it.
Edit, on your questions: correct the text and press Send (or Enter). If it is the last question, it is asked again in place. If it is an earlier one, the chat carries on in a new conversation from there, and the current one stays in the history with everything said afterwards.
Good answer and Bad answer, on the answers: they are noted in the conversation, on your computer. They are not sent to your AI provider, which has nowhere to receive them.
Regenerate, on the last answer: it asks the same question again, with what had been said up to then, and the new answer replaces the old one. It is another call and is paid like the rest.
Continue in a new thread from here, on the answers: it opens a new conversation with what was said up to that message, the same papers and the same model. The current one stays in the history.
While JUDLEX is answering or working, the buttons that change the conversation wait for it to finish.
