Yes. To protect your privacy and uptime, I, Librarian does not include a remote deactivation feature (kill-switch). Once a license is issued, the software is fully autonomous on your hardware. Because we cannot remotely revoke access, all sales are final. We strongly encourage you to run our software in evaluation mode and try online demo before purchasing.

Absolutely. You can scale your license as your team grows. Please contact support for a quote to add more users to your existing installation.

Maintenance and security updates (e.g., version 6.0.X) are always included. Major feature upgrades (e.g., version 6.1, 6.2) may require an upgrade fee, though existing license holders receive a significant discount.

Technical support is not included in the base license price. However, online documentation is available. For organizations that require direct assistance, dedicated email support is available as an annual subscription. The cost is a $6 per user (minimum $18), per year.

Yes. Your databases, documents, and user data never leave your server. We do not collect any telemetry or software usage data. The only information we log is your server's IP address to verify license compliance. This process does not track what you are reading or storing.

All core features, like storing, organizing, and searching your personal library work 100% offline and no library data ever leaves your server.

A yearly license requires a periodic internet connection to verify a valid expiration date. For users who require a strictly offline or air-gapped environment, we offer a perpetual license which has no internet requirement for validation.

There are also optional integrations with third-party APIs (PubMed, Gemini AI, Google OCR, etc.). If you choose to use these features, only the specific data required for that request (e.g., a search query or a document for OCR) is transmitted to the provider. These features are strictly opt-in; if they are not used, no document data is ever transmitted.

Yes, you can create unlimited number of libraries.

Each license is for a single production server. However, we allow additional installations for temporary testing, staging, or development environments to ensure your library remains stable during server migrations or updates.

Your license will expire and the software will revert to "Evaluation Mode." To maintain full access to your user accounts and features, you should renew your license annually or upgrade to a Perpetual License.

Your library remains yours. The I, Librarian core is a self-sufficient, statically-compiled Linux 64-bit Go binary. It makes use of standard system utilities (Poppler, LibreOffice) to process your files. Because these are the industry-standard tools for document handling, your installation is not tied to a proprietary cloud service. As long as you have a server that can run these common utilities, I, Librarian will continue to function exactly as it does today, regardless of our company's status. There is no "phone home" requirement to keep the software running.

We provide a streamlined Docker-based pipeline. This eliminates the need for you to manually install and configure dependencies like LibreOffice or Poppler on your host OS. If you have Docker installed on a 64-bit Linux server, you can have I, Librarian up and running in minutes.

Currently, we provide a native Linux 64-bit binary. While you can run Docker on Windows or macOS (via Docker Desktop), we officially support and recommend Linux-based server environments for production use. We suggest testing your specific environment using our Evaluation Mode before purchasing.

Yes. We believe in zero vendor lock-in. Your metadata are stored in a single SQLite database, and your PDFs are stored in a standard file structure on your server.

I, Librarian is highly optimized, but requirements depend on your library size and user activity. Here are our recommended guidelines:
