A schedule the front desk gets on day one
Day and week views, recurring appointments, lunch and holiday blocks, a waitlist and an arrival queue with priority. One tap calls the patient on the waiting-room TV.
The medical record that keeps working when the internet doesn't.
Scheduling, charts, prescriptions, insurance billing and WhatsApp in one place — working even offline. Set it up yourself in minutes. 14-day free trial, no card needed.

Internet down? The visit goes on.
Celsor saves to your device first, encrypted, and sends it to the cloud right after. The schedule, today's patient charts, prescriptions and forms stay open when the connection drops — and everything uploads on its own when it's back.
Systems that live 100% in the cloud stop when the connection drops. In Celsor, the cloud keeps the copy — the visit happens on your device.
Don't type a thing. The chart fills itself in.
Tap “Record visit” and talk to your patient as usual. Laennec, Celsor's clinical scribe, transcribes the conversation, fixes medical terms, drugs and tests from context, and puts each detail in the right chart field. You just review and insert.
- Record the visitWith the patient's consent recorded on file. Speak normally — no dictation.
- Laennec organizes itComplaint, history, medications, exam and plan, each in its own field, in chart language.
- You review and insertNothing enters the chart without your tap. The audio isn't kept — only the text.
Named after René Laennec, the physician who invented the stethoscope — and the art of listening to the patient.
Compare before you decide
Scores from 0 to 5. Celsor against the three most common kinds of practice software.
 Celsor | Competitor A | Competitor B | Competitor C | |
|---|---|---|---|---|
| Offline use | ★★★★★ | ★★★★★ | ★★★★★ | ★★★★★ |
| AI power | ★★★★★ | ★★★★★ | ★★★★★ | ★★★★★ |
| Auto-filled chart (no typing) | ★★★★★ | ★★★★★ | ★★★★★ | ★★★★★ |
| AI reports in seconds | ★★★★★ | ★★★★★ | ★★★★★ | ★★★★★ |
| AI prescriptions in seconds | ★★★★★ | ★★★★★ | ★★★★★ | ★★★★★ |
| Value for money | ★★★★★ | ★★★★★ | ★★★★★ | ★★★★★ |
A, B and C are kinds of software, not brands: A = cloud record without AI; B = cloud record plus a separate AI app (copy and paste); C = software installed on one computer, without AI. Scores follow those definitions. Installed software works offline, but only on that one computer.
The three reasons doctors switch systems
“The internet went down and the visit stopped.”
In Celsor, the visit keeps going offline and syncs later. Nobody waits for the Wi‑Fi.
“Switching systems is scary.”
You upload your old system's export. Celsor shows what it understood, flags duplicate patients and saves nothing until you confirm.
“I don't have time for training.”
Celsor teaches itself: a getting-started guide, help on every screen and an assistant that answers right away.
Everything your practice uses, in one place
Each feature below is a real Celsor screen with made-up data.
A chart that fits your specialty
Templates for 34 specialties, blocks you switch on and off, text shortcuts (type /ret and the text appears) and each field's history one tap away. Calculators like PREVENT, CHA₂DS₂‑VASc, HAS‑BLED, RCRI and Glasgow inside the visit — and for eye care, refraction, pachymetry-corrected IOP and a glasses prescription in one click.
Prescriptions and forms without retyping
In Brazil: search the CMED/Anvisa drug database, with antibiotics and controlled drugs detected automatically and printed in 2 copies. Plus glasses prescriptions, medical certificates, reports with images and your signature on paper.
Insurance claims checked before they go out
In Brazil, TISS consultation and SP/SADT claim forms with the TUSS code table, required fields checked before sending, XML batches, payer responses and denial tracking. Celsor also flags insured visits that still have no claim.
Billing and payouts without a side spreadsheet
Payments by Pix, card, cash or transfer, accounts and cash box, per-professional payout rules, and production, visit and financial reports in CSV or PDF.
Made for the whole day
Light or dark theme, crisp type and everything in view without scrolling: each block folds into a one-line summary, and Celsor remembers how you like to see it.

- Patient portalPatients download reports and documents from a portal with their own login.
- Waiting-room TVThe front-desk TV calls patients by name and room. Pairs with a code.

AI suggests. You decide.
Everything the AI writes arrives as a draft labeled “AI suggestion”. Nothing goes into the chart or a prescription until you review and save it.
- Dictation and visit transcription straight into chart fields — recording only with the patient's consent on file.
- Assisted reports from the findings you enter, including the exam image.
- Prescription suggestions from your plan, checked against the patient's allergies, age and weight.
- An assistant that knows Celsor and answers how-to questions on the spot.

Bringing your data over is the easy part
Upload whatever your current system exports: spreadsheets (CSV and Excel), dBase/FoxPro databases, SQL dumps, JSON or one ZIP with everything. Celsor recognizes formats from well-known systems, shows what it understood before saving and checks for duplicate patients.
- Nothing is saved until you confirm.
- Duplicate patients are flagged for you to decide.
- Your data is yours: export everything whenever you want, in one file.
Health-data security, no fine print
- Encrypted on the device
What's kept for offline use is encrypted (AES‑256) in the browser itself.
- PIN and shared computers
Lock the device with a PIN. In shared-computer mode, nothing is kept.
- Every clinic isolated
Data is separated by clinic; a user only reaches the clinic they were added to.
- Audit log
Sign-ins, prints and exports are logged.
- Patient consent
Visit recording only with consent recorded on the patient's file. The clinic confirms it informs patients about AI use.
- Plain terms
Read the Terms of use and the Privacy policy (in Portuguese).
Open pricing. No lock-in.
You pay per healthcare professional, with no fixed clinic fee. Front-desk staff are free. Each additional professional costs less.

Built by someone who sees patients.
I see patients every day, and I got tired of watching visits stop because the internet went down or the system was too hard to use. I built Celsor to work the way a practice works: fast, independent of the connection, and with no need to call support.

Frequently asked questions
Does it really work offline?
Yes. Everything you save goes to your device first, encrypted, and uploads to the cloud as soon as there's a connection. The schedule and today's patient charts are kept on the device, so you see patients and print prescriptions and forms with no internet. Signing in on a new device for the first time, or using AI and WhatsApp, needs a connection.
Where is my data stored?
In Google's cloud (Firebase / Google Cloud), separated by clinic, plus an encrypted copy on the device for offline use. Details are in the Privacy policy (in Portuguese).
Do I need to install anything?
No. Celsor runs in the browser. If you like, install it as an app on your computer, tablet or phone straight from the browser, no app store.
Does it work on phones and tablets?
Yes. Screens are built for small displays too: scheduling, front desk and charts work on a phone with the navigation bar at the bottom.
Can I bring data from my current system?
Yes. Upload your old system's export (spreadsheets, dBase/FoxPro databases, SQL dumps, JSON or ZIP). Celsor shows what it understood, flags duplicate patients and saves nothing until you confirm.
How does the free trial work?
You get 14 days with everything in Max, no credit card. When it ends, pick Pro or Max and add payment only if you want to continue.
How do I cancel? Is there a contract?
No contract. Cancel whenever you want, on your own, in Settings › Subscription. Access continues until the end of the period you've paid for, and you can download all your data.
Do front-desk staff pay?
No. Pricing is per healthcare professional. Front-desk staff are included at no cost.
Does it handle insurance claims?
In Brazil, yes: TISS consultation and SP/SADT claim forms, the TUSS code table, required-field checks, XML batches, payer responses and denial tracking.
Will it work for my specialty?
Celsor includes chart templates for 34 specialties — from internal medicine and pediatrics to psychology, physical therapy, dentistry and occupational health — and you can build your own from any blocks you like. Eye care has dedicated tools such as refraction and glasses prescriptions.
Does the AI decide anything on its own?
No. The AI only suggests: the text arrives labeled “AI suggestion” and nothing is saved until you review it. Recording a visit requires the patient's consent on file.
