of brief-writing time goes to the facts, not the law
Drafting the statement of facts absorbs most of the work — leaving less time and energy for the legal argument, where a lawyer actually earns their fee.

Source management & document intelligence
Half the document work.
Full command of every file.
Run multiple matters in parallel without losing the thread.Briefs, exhibits, timelines and sources live in one workspace — with an AI that supports your reasoning, not one that replaces it. It works from your documents, brings order to complex material, and answers only from the sources you give it.
Built around how lawyers actually work — not another generic chatbot.
Probatio Vincit is being shaped with practising lawyers whose matters run heavy on evidence: court filings, exhibit bundles, and the same sources cited case after case.
Employment cases tend to look alike — but every client has their own facts, their own dates, their own paper trail. I used to keep it all straight from memory, with twenty folders open at once.
With Probatio, I reuse what's meant to be reused and instantly check what's specific to each case — without ever mixing up two matters.

Employment lawyer, Studio Legale Palliccia
We take on hundreds of cases a year. The hard part isn't writing the brief — it's keeping the thread as you move from one file to the next.
With Probatio I can see the facts, exhibits and deadlines of every matter at a glance. Clients get answers faster, and we work with a clearer head.

The problem, in numbers
The invisible work that eats your time and focus.
Before you ever get to the law, the day disappears into sorting files, hunting for exhibits and double-checking AI output. Here's what it costs.

hours in a lawyer's day are actually billable
The rest disappears into admin, formatting and file-wrangling — work no client pays for.

court cases caught filing AI hallucinations since 2023
Courts have found significant AI-produced hallucinations in 736 cases since April 2023, more than two-thirds of them in the US. The lawyer, not the tool, answers for them.

legal AI use year over year
Active use of generative AI among legal professionals rose from 14% in 2024 to 26% in 2025. AI has arrived — the difference is how you use it.
Thomson Reuters, 2025 Generative AI in Professional Services Report
One workspace for the four pillars of your practice.
Work slows down when facts, exhibits, sources and drafts drift apart. Probatio keeps them connected — so you can get back to lawyering.
Documents
Write the brief. Skip the formatting.
Draft and restructure freely — layout, export and court-filing compliance are Probatio's problem, not yours.
Exhibits
Naming, numbering and tying each file to the fact it proves takes seconds, not an afternoon.
The file keeps itself in order — even at two hundred exhibits.
Intelligentia
Every person, date and reference on one map.
Reopen a file after six months and find the case exactly as clear as the day you closed it.
Sources
The rulings, statutes and references you've collected over the years are your professional capital.
Here, they become a personal library: organised, annotated, always ready to cite.
Probatio AI
An AI that knows its place.
You won't ask it to invent an appeal or to unearth the argument that wins the case — that's your craft. Probatio AI simply knows the file better than anyone, and handles the work that drains your day: it finds the right passage, cross-checks dates against exhibits, and verifies that every citation holds up. Every answer comes with its source. And when it doesn't know, it says so.
It's useful precisely because it doesn't pretend to be a lawyer.
Features that earn their keep.
No grand promises — just fixes for the least rewarding hours of legal work.

Built for lawyers who want control — not another black box.
Question How is this different from AI tools that generate filings?
Answer
They answer different questions. Generation tools produce a draft from your premises: the output arrives immediately, but checking references, facts and logic remains entirely on you. Probatio is the space where the filing is built — facts, exhibits, sources, drafting and filing in one place — with AI that works only on the case-file material and cites the exact point it answers from. And the two worlds can coexist: you can bring into Probatio a draft generated elsewhere, connect it to the exhibits, and bring it under control.
Question Will it fit the way I already work?
Answer
Yes. Probatio is built around the work you already do — Word and PDF export, exhibit bundles, source archives, filing preparation. Early access starts from your habits; it doesn't overturn them.
Question Can I trust the AI?
Answer
You shouldn't take Probatio on faith — that's the point. Its value lies in letting you work on controlled material: linked exhibits, reusable sources, verifiable facts. Responsibility for review stays with you; the system just makes that review simpler and easier to trace.
Question Do I need to learn prompt-writing?
Answer
No. Probatio guides you step by step: select a paragraph, a fact, a source or an exhibit, and choose a specific action.
Question Is there a long setup process?
Answer
Quite the opposite. Probatio removes the friction up front — it renames files, orders sources, extracts facts, builds timelines and prepares exhibit lists for you.
Question Is it trying to replace the lawyer's judgement?
Answer
No. Probatio exists to support your reasoning by making facts, questions, documents and sources easier to examine. The goal isn't automated legal reasoning. The goal is a case prepared under your control.
Question Is this secure enough for legal work?
Answer
Security, data handling and deployment options are settled before you ever touch a live matter: clear installation boundaries, demos on sample data, and a review of your workflow.
Prepare every filing with the evidence always at hand.
Probatio Vincit is for legal professionals who want drafting, exhibits, sources and AI assistance in a single, orderly space — built around professional review, not around the machine.
