AI and WhatsApp for Mexican notary offices, with case tracking

More cases started and fewer “how is my case going?” calls, with the same team.

FILTRA answers your office’s WhatsApp at any hour, tells clients which documents each case needs, hands the chat to the right case manager and answers “how is my case going?” with the note they left. Your notarial software stays as it is.

A Mexican notario público is not a US notary public: it is a lawyer appointed by the state who drafts and certifies property sales, wills, estates and powers of attorney. FILTRA is built for their offices.

Please bring your INE voter ID, your tax status certificate, the prior deed, this year’s property tax receipt and Infonavit’s instruction letter. Shall I pass your details to Daniela, who handles mortgage releases?9:40 pm
Yes, please9:41 pm
Done. Daniela will write to you here first thing tomorrow.9:41 pm
Sample conversation

From the first question to delivery

Answering is only the start. What moves the office’s revenue is everything that happens to the case afterwards. Add-on modules are priced separately.

  1. 1The first message
    Included
    Answers in seconds, at night and on Sundays too, and understands the case even when the client describes it in their own words.
    Nobody goes to another office that same afternoon
  2. 2The requirements
    Included
    Says which documents the case needs, exactly as your office reviewed them, and whether it calls for a consultation.
    Clients arrive with what is needed
  3. 3The case manager
    Included
    Hands the chat to whoever handles that type of case, with everything the person said, and to the one with the lightest load.
    The front desk stops being the bottleneck
  4. 4The consultation
    Included
    Explains that the attorney gives the price at the consultation and tells the client what to bring, without quoting figures.
    Nobody shows up with “I was told another price”
  5. 5The documents
    Add-on module
    Receives documents over WhatsApp, logs the day each one was requested and the day the client promised it, and reminds them.
    Cases stop waiting on a missing document
  6. 6The data in each document
    Add-on module
    In one click it reads the ID, tax certificate, civil records or deed the client sent and leaves the data ready to copy into your system. It flags what is uncertain; it never makes it up.
    Nobody retypes a deed again
  7. 7“How is my case going?”
    Included
    Answers with the stage and the note the case manager left. It never makes up a status.
    Fewer calls interrupting the team
  8. 8The update
    Included
    When the case manager moves the stage, the client gets a message with their file number and what comes next.
    Clients find out without calling
  9. 9Delivery
    Add-on module
    Lets the client know it is ready to pick up, and invites happy clients to leave a Google review.

What your office loses today without seeing it

RevenueConsultations that leave to think it overMore than half walk out without leaving a deposit, and almost nobody writes to them again.
CostsThe “how is my case going?” that interruptsOne case manager can get ten calls a day asking the same thing, more when the case is running late.
ReputationThe “they never answer” reviewsPeople who get no answer on WhatsApp or by phone write to another office and, sometimes, leave one star.
RiskThe case that rolls into next yearIf it is not signed before December, it needs new documents and a new quote: it starts over.

Which questions are still unanswered?

What FILTRA does not know, it asks the case manager. Every open question stays in view, with who has it and since when, and if it goes cold, FILTRA flags it.

Where do cases stall, and waiting on whom?

The days in each stage and whose turn it was: the client, the office or the Registry. Every bottleneck comes with its cause and what can be done about it.

What it deliberately does not do

In a notary office, what the assistant does not say matters as much as what it does.

It does not quote pricesThe attorney gives the price at the consultation. FILTRA says so and never quotes figures, so nobody shows up saying they were told another price.
It does not pass one client’s file to another“It was filed at the Registry on Tuesday” belongs to one person and nobody else. What the case manager answers about a case stays with that case.
It does not ask for documents twiceClients whose case is already open are not asked again for deeds or ID. If something else is needed, their case manager asks for it.
Your office at the center

It works with your team, not instead of it

Your case managers know every case and every client. What they log in one click, FILTRA turns into answers for the client and into the attorney’s report. The more it is used, the more work it takes off their plate.

One click and a noteThe only thing anyone logs is the stage and a short note when something moves. FILTRA picks up the date of each document from the chat.
What they log comes back to themEach note answers that client’s “how is it going?” on its own. Fewer calls to the case manager, and the attorney sees the week without asking.
The overview shows casesWhere each file is stuck and what it is missing: from the client, the office or a government office.
Your team decidesAny case manager can take over a conversation when needed, and the assistant pauses in one click. What it is taught once, it knows the next time.

Frequently asked questions

Is this for notaries public in the US?

No. A Mexican notario público is a lawyer appointed by the state to draft and certify property sales, wills, estates, powers of attorney and company deeds; a US notary public only witnesses signatures. FILTRA is built for notary offices in Mexico and the way their cases move.

What does an AI agent do in a notary office, and what not?

It answers at any hour: it identifies the case even when the client describes it in their own words, says which documents it needs, hands the chat to the right case manager and answers “how is my case going?” with the note they left. When the case moves to another stage, it lets the client know.

Does it replace our notarial software?

No. The protocol, the deeds and the indexes stay in your notarial software. FILTRA handles the conversation with the client and the tracking of each file: which documents are missing, what stage it is in and who has it.

How does case tracking work?

Each case has its own file, with every document and its dates: requested, promised, delivered. The case manager moves the stage in one click and leaves a short note; with that, FILTRA answers the client and lets them know. It is the Case tracking module, priced separately.

Does the assistant quote fees?

No. The attorney gives the fees at the consultation; the assistant says so and tells the client what to bring, so nobody shows up saying they were quoted a different price.

How much does it cost?

From US$159 a month before tax for WhatsApp service. The Full office bundle, with tracking for every case and the notary’s reports, is US$489 a month. No contract; the details are in the pricing on this page.

Will my clients be talking to a robot?

It answers only with what your office entered. What it does not know, it asks the case manager, and it tells the client they will get an answer right there. Your team sees everything live and can take over the chat whenever they want.

Does this change how we work?

No. Case managers keep running their cases in your notarial software. What is new is moving the stage in one click and leaving a short note; with that, FILTRA answers, sends updates and builds the attorney’s report. If a note is missing, FILTRA tells the client their case manager will confirm: it never makes anything up.
