Carl

Frequently asked questions about Carl, the all-in-one software for therapists

The questions we hear most often before people get started. If yours is not here, write to us: we reply within 24 hours.

Carl in practice

Which professions is Carl designed for?

Carl is designed for therapists and support professionals, whatever their approach: clinical psychologists, psychiatrists, psychotherapists, coaches, sophrologists, hypnotherapists, EMDR practitioners, sex therapists, and more than 110 support professions. If your practice is not explicitly listed here, Carl will very likely suit it too. See, for example, Carl for hypnotherapists or psychotherapists.

Can I use Carl on my phone?

Yes. Carl works directly in your browser on both phones and computers, with the same features on each. Many practitioners dictate from their phone between sessions and return to the report on their computer later.

Do I need to install an app?

No, there is nothing to download. We simply recommend adding a Carl shortcut to your phone’s home screen and your computer desktop. Carl then opens in one tap, just like an app. On mobile, a button on your Profile page creates this shortcut for you.

Do my clients need to create an account?

No. Your clients do not need to do anything. Carl works entirely on your side as part of your daily organization — they have no account to create, app to download, or password to remember.

Does my calendar sync with Carl?

Yes, with Google Calendar. Your appointments appear in Carl, and sessions you create in Carl are added to your calendar, so you can keep using the calendar you already know.

Does Carl diagnose or interpret sessions?

No. Carl never replaces your clinical expertise or makes judgments about your clients or sessions. Its role is limited to helping you organize and prepare your work — clinical assessment and interpretation remain entirely your responsibility.

How is Carl different from Doctolib and other software?

Carl is all-in-one software: dictated reports, client records, scheduling and online booking, video sessions, invoicing, and accounting, all in one subscription. Doctolib is mainly used to help new clients find you, while most practice-management tools cover administration but still leave you to write reports by hand. Our comparison provides the full details and sources.

Dictation and reports

Which language can I dictate in?

Any language. Dictate in the language of your choice and your report is returned in that language. If you see clients in several languages, there is nothing to change between sessions.

How long can I dictate for one session?

Up to fifteen minutes per report. That is much longer than most people need in practice: practitioners usually describe a session in two to four minutes because speaking is faster than writing.

Can I edit what Carl has written?

Yes. You can edit the report, summary, and next-session section by hand. Carl gives you an already structured text; what you keep or rephrase is entirely up to you. It is your record, not ours.

Does Carl take previous sessions into account?

Yes. To prepare a report, Carl draws on the client’s history: it can highlight a recurring topic or remind you what you planned to revisit. It still does not interpret anything; it organizes what you say in light of what you have already said.

Are report sections always the same?

No. They adapt to what you dictate and to your practice: a hypnotherapy session is not described like long-term care, and if you mention supervision, a dedicated section appears.

Is there a limit on the number of reports?

No. Your subscription includes unlimited reports, whatever the volume of your practice.

Calendar, invoicing, and accounting

Can I offer online booking to my clients?

Yes. You get a booking page in your name with your actual availability, session types, durations, and prices. Its link can go anywhere people look for you: your website, Google Business Profile, or social media. You control buffers between sessions, booking and cancellation windows, time off, and a daily session limit that accounts for every appointment that day.

Are video sessions included?

Yes. A video link is created with the appointment. Neither you nor your clients need to install anything, and there is no separate video tool to pay for.

How does invoicing work?

A PDF invoice is generated from the session in one click, with your legal details and numbering. Unpaid invoices are followed up automatically, so you no longer have to chase payment or remember to do it.

Does Carl handle mandatory electronic invoicing?

Yes, without any manual work on your side. Your invoices are converted to the required format and sent automatically through Super PDP, an approved platform registered by the French tax authority. Two dates matter: since September 1, 2026, every business must be able to receive an electronic invoice; from September 1, 2027, self-employed professionals and very small businesses must also issue them. The issuing requirement applies only to business-to-business invoices — invoices sent to your clients do not change format. Learn more about electronic invoicing.

Does Carl handle my accounts?

Yes. Your payments are recorded as sessions take place, you add expenses such as rent, supervision, training, and software, and you can read your results by month, quarter, or year.

Which statistics can I track?

You can track session numbers, active clients, new clients, revenue by period, and a chart showing how these figures evolve. This helps you understand your practice and see the effect of your communication efforts.

Your data and security

Where is the data stored?

Your data is hosted in the European Union by Scalingo, a certified Health Data Hosting provider.

What security measures do you use?

Your data is encrypted both in transit and at rest and hosted by a certified Health Data Hosting provider. Audio recordings are deleted as soon as transcription is complete, and your data is never used to train an artificial intelligence model. Read the full details of our guarantees on the Security page.

Are audio recordings kept?

No. Audio recordings are automatically deleted as soon as transcription is complete — they are never retained beyond that process.

Is my data used to train your artificial intelligence?

No. Your data and your clients’ data are never used to train our artificial intelligence models or those of our technology partners. They are used solely and strictly to make Carl work for you.

Do you share my data with third parties?

Never for commercial purposes. Your data and your clients’ data are not sold, rented, or used for marketing or advertising — by Carl or by anyone else. You remain in control of your information at all times.

How does Carl protect my data under the GDPR?

Your data is hosted in the European Union by a certified Health Data Hosting provider. It is never sold or used to train an artificial intelligence model, and you can request an export at any time. Details about processors and retention periods are available on the Security page.

Can I retrieve my data if I leave?

Yes, always. Your reports and client records belong to you. We will send them to you on request, without conditions or fees. Leaving Carl does not mean losing anything you have built up.

Getting started with Carl

Can I switch to Carl if I already use other software?

Yes, very easily. From your Carl profile, you can import existing data from an Excel, CSV, PDF, or ZIP file, and it is transferred automatically. You do not need to change everything at once: start with the features that help you most, then adopt Carl gradually at your own pace.

Do I need training to use Carl?

No. Carl was designed to be easy to use from the first few minutes, with no special training or technical support required. The tool adapts to how you work, not the other way around.

How can I reach you with a question or problem?

Use the in-app chat or email us. We reply within 24 hours at most, and usually much sooner. You will hear from the Carl team, and one of its co-founders, Quentin, is himself a psychotherapist and hypnotherapist.

The subscription

How much does Carl cost?

There is one plan, Carl Essential, at €29.90 including tax per month, with no tiers and no features reserved for a higher plan. There is no commitment, and you can cancel at any time. See everything included on the pricing page.

Can I try Carl for free?

Yes, with no strings attached. You can try Carl free for 30 days, with no payment card required and no commitment at the end of the trial. You have time to test the tool in your daily practice before deciding whether to continue.

I am starting my practice. Is there a discount?

Yes. If you started your practice less than a year ago, Carl is 50% off for the first few months. Write to us to claim the discount.

Can’t find your question?
