The record

Purpose: QardQntac is an open-source, self-hosted business-card scanner that extracts contact details from card photos using AI.
Workflow: Users can scan or upload a card image, review and correct extracted contact fields, tag contacts, and export or sync them.
AI providers: AI extraction supports locally hosted Ollama models and cloud providers OpenAI, Anthropic, and Google Gemini.
CardDAV: Contacts can sync to any standard CardDAV server, with Nextcloud, Radicale, and Baikal listed as examples.
Export: Contacts can be downloaded as standard .vcf files, and tags are exported as the vCard CATEGORIES field when syncing.
Authentication: Sign-in uses passwordless magic links sent by email when SMTP is configured; without SMTP, links appear in server logs.
Access control: Administrators can restrict sign-ins by email domain or disable new account registration.
Data handling: The project says data stays on the self-hosted server unless a cloud AI provider is selected; its Ollama option runs models locally and is described as fully private.
Languages: The interface supports English and French, configurable through an environment variable.
Deployment: The project provides Docker Compose and container deployment instructions and says it runs on a Linux server with Docker and Node.js.
Mobile camera requirement: Using the camera scanner from a phone or tablet requires serving the app over HTTPS with a valid certificate.
Database limitation: The embedded database fallback is explicitly described as not suitable for production; PostgreSQL can be configured through DATABASE_URL.
License: The repository identifies the project as MIT licensed.
Privacy: The project says data stays on the user's server unless they choose a cloud AI provider; Ollama runs models locally without internet access.
