Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
Template-driven AI writing and image generation for marketers who need drafts fast
Roughly 38 ready-made use-case templates for blogs, email writing, Google ad copy, video scripts, landing page copy, business strategies and social media marketing. Custom use cases can be created and saved.
Turn a short brief or keyword list into a reviewable draft, then edit and update it in place. Higher tiers add an AI Article Writer, bulk processing and a Google Docs-style Sonic Editor.
Convert text prompts into royalty-free images with no watermark, with resolution limits set by plan (up to 1024x1024 on the Platinum tier).
The Platinum tier bundles a ChatGPT-like assistant named Artifism Bot, plus chatbots, voice cloning minutes, video and page generation modules inside the same account.
