JabRef is a cross-platform reference manager for BibTeX and BibLaTeX libraries. It can import records from scientific catalogs or identifiers, extract metadata from PDFs, organize collections and attachments, merge duplicates, and insert citations into external writing tools. Browser extensions help capture new references, while teams can synchronize a library through SQL; a separate JabKit command-line interface is also available.

Open Science Desktop combines exploration, literature review, experiment code, notebooks, figures, reports, runs, and paper writing in one macOS, Windows, and Linux application. Each artifact can be traced back to its inputs, code, environment, model output, and conversation, while a bundled OpenCode sidecar keeps models, skills, and MCP connectors replaceable. Workspace data stays local by default, although selected content may still be sent to the model provider configured for a task.

Saga Reader is a desktop reading application that gathers online information from user-defined interests through search and RSS. It can pass collected articles to a local or cloud LLM for summarization, translation, guidance, and an interactive reading conversation. Interest prompts, source articles, and processed content are stored on the user's computer rather than in a hosted account. Retrieval still depends on available search providers, while AI processing depends on the model backend the user configures.

PrismOS-AI is a local-first desktop assistant that uses Ollama models to work with conversations, images, and office documents while storing knowledge across sessions. Several specialized agents can debate a request before writing the result into its persistent graph, with desktop surfaces for retrieval, global access, and patterns in past interactions. It runs on Windows, macOS, and Linux, but the full experience depends on suitable hardware and locally available models.
