ChartLite is a free, open-source EMR that turns spoken consultations into structured medical records. No server. No internet. No cost. Built for the clinics that need it most.
The world has plenty of electronic medical records systems. OpenMRS needs a server room. Epic needs a budget. DHIS2 needs constant internet. ChartLite needs a phone and a voice.
Servers, licenses, IT staff, multi-year contracts, vendor lock-in
Open source, runs on a $100 phone, no server, no license, no lock-in
Cloud-dependent, breaks during outages, slow on 2G/3G networks
SQLCipher encrypted on-device. Syncs via SMS or BT when available
Forms, dropdowns, checkboxes. Adds 15 min per patient encounter
On-device AI extracts diagnoses, meds, vitals, plan. One tap to save
Complex interfaces designed for IT departments, not clinicians
Speak like you already do. PIN to login. That's the whole interface
A complete EMR platform designed for primary healthcare in resource-constrained settings.
Speak naturally during the consultation. On-device AI extracts diagnoses, medications, vitals, and treatment plans in real-time using a 3-tier pipeline.
SQLCipher AES-256-GCM encryption with EncryptedSharedPreferences. FHIR R4-native schema. Full functionality without any internet connection.
PIN-based authentication with 6 roles (Admin, Doctor, Nurse, Pharmacist, CHW, Clerk). Full audit trail. PBKDF2-HMAC-SHA256 hashing.
50-test clinical catalog covering hematology, chemistry, infectious diseases, and urinalysis. Order, collect, and result with reference ranges and abnormal flagging.
Track drug inventory with atomic dispense/receive operations. Low-stock alerts, batch tracking, expiry warnings. Integrated with country formularies.
Real-time drug-drug interaction checking, dosage validation, allergy alerts, and vital sign monitoring. Protects patients at the point of care.
12 WHO-based treatment protocols for malaria, HIV, TB, diabetes, hypertension, and IMCI. Step-by-step guidance with red flags and medication dosing.
Automated multi-language reminders in English, Zulu, Xhosa, Afrikaans, and Amharic. Reduce no-shows for follow-up, chronic care, and immunization visits.
Offline searchable directory of health facilities with GPS coordinates and Haversine distance calculation. Find the nearest referral hospital instantly.
WHO Expanded Programme on Immunization schedule. Track doses administered, compute next due dates, flag overdue vaccinations.
Comprehensive patient view with sparkline vital sign trends (BP, HR, Temp, SpO2), active medications, allergies, conditions, and recent encounters.
Export aggregate data directly to DHIS2 for national health information systems. Built-in mapping from clinical encounters to DHIS2 data elements.
Designed for clinicians who don't have time to type. Speak naturally and let the AI handle the rest.
The clinician speaks naturally during the consultation. No special vocabulary or commands needed.
On-device AI processes the audio and extracts structured clinical data: diagnoses, meds, vitals, and plan.
A structured SOAP note is generated for the clinician to review and approve with a single tap.
The record is encrypted and saved. Safety alerts fire. Insurance claims are auto-generated. Follow-ups scheduled.
ChartLite isn't a prototype. It's production-grade clinical software with real engineering depth.
Cascading fallback: Gemini Nano (on-device LLM) → Qwen/Claude API → Regex+Fuzzy matching. Always extracts structured data, even without internet.
