A local-first AI desk with reusable agents, documents, memory, and workflows; less campaign theatre, more settings.
licenseMIT
runsyour machine or their cloud
installDesktop installer for macOS/Windows/Linux, or Docker for a self-hosted web instance
enginesLocal llama.cpp models plus Ollama, LM Studio, LocalAI and many cloud APIs including OpenAI, Anthropic, Gemini, Bedrock, Azure, OpenRouter and Mistral
dataDesktop data stays in the app's local storage; self-hosted data is stored in the mounted server storage and chosen vector database (LanceDB by default), while prompts sent to cloud models leave the machine
the catch vs JasperIt can hold brand documents and reusable agents, but it lacks Jasper's managed brand governance, campaign workflows, approvals, and marketing-team controls.
setupThe installer is easy, but useful results still require downloading a local model or supplying a model-provider API key

A desktop ChatGPT-shaped box with local models and reusable assistants; excellent at prompts, blissfully unaware of your marketing calendar.
licenseApache-2.0

installDownload the macOS, Windows or Linux desktop installer
enginesBuilt-in local inference via llama.cpp/llama-server plus OpenAI-compatible APIs and connectors such as OpenAI, Anthropic, Gemini, Groq, Mistral and OpenRouter
dataThreads, assistants, settings and downloaded model files live in Jan's local data folder; only requests sent to configured cloud providers leave the machine
the catch vs JasperIt is a general assistant with saved instructions, not Jasper's coordinated campaign workspace with brand controls and team operations.
setupLocal use requires downloading a multi-gigabyte model and enough RAM; cloud use requires an API key
