DISCOVERCreate an international law firm app
International tax firm app: an assistant that answers your clients in their own language
Expats, non-residents, families and companies spread across several countries ask their questions in their own language; the assistant answers from your analyses, then the client books an appointment.
Build your firm's native iOS and Android app without writing code: the Chatbot answers in the language of the question from your content, appointments are booked in each lawyer's calendar, and your analyses arrive as notifications.

Bookable appointments, wherever the client is
First consultation, follow-up on a cross-border case: clients book a slot that is actually free
Your clients open Appointment booking, pick the section that matches the lawyer and the type of appointment, then confirm a free slot, synced with the lawyer's Google Calendar. Slots are shown in the firm's local time: state its time zone in the name of each section. With every booking, you and your client receive a confirmation email.
An assistant that answers in the client's language
It relies on your analyses, even when they are published in a single language
“Où dois-je payer l’impôt sur mes revenus locatifs ?” The Chatbot searches the articles, events and map points published in your app, then answers in the language of the question: your analyses written in English also serve the French-speaking client. Advice on a situation remains yours.
The details of a multi-country case, before the meeting
A form with a file field for residence, income and assets
Country of residence, country of income, type of assets, attached documents: build the Form section you need. You get an email for each submission, and the consultation starts with the facts in hand.
Your analyses, in the app and as notifications
Tax treaties, reforms, case law: your clients are alerted wherever they are
Publish your analyses in the app and alert your readers with a push for each new publication, whatever their country. With User groups, keep some memos for clients under contract.
Opening the app to international clients: what you configure, in practice

International tax firm app: frequently asked questions
Does the assistant answer in the client's language?
Yes: the Chatbot answers in the language of the question, from the content published in your app. A French-speaking client gets an answer in French drawn from your analyses, even if you wrote them in English.
Which content does the assistant rely on?
On the articles, events and map points you choose, section by section, including external feeds connected to the app. Its knowledge base is refreshed whenever content is added or updated.
Can the assistant give an opinion on a case?
It answers from what you have published; it does not replace a consultation. For a specific situation, the client books an appointment in the same app.
Can clients abroad book an appointment?
Yes, in the chosen lawyer's section, synced with their Google Calendar. Slots are shown in the firm's local time: state the time zone in the section's name.
Do I need to translate all the app's content?
Not for the assistant, which answers in the language of the question from your content. Your articles stay in the language you publish them in.
How much does the Chatbot cost?
It is added to your plan at its own price, shown in your currency on the pricing page. A native iOS and Android app starts with the Premium plan; developer accounts are paid directly to Apple and Google.
