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.
AI agents that run your email and document work
Agents read email threads, pull attachments, run lookups, apply your policies, and write replies automatically, covering tasks from routine answers to multi-step document chasing.
Serif requests paperwork, reads what comes back, checks it against what you actually need, and keeps following up until the file is complete — ideal for closings, claims, and intake packets.
When an agent is unsure how to proceed, it routes the job to the right person for review, so automation handles volume while judgment stays with your team.
Manage addresses like info@, support@, billing@, and closing@ from a shared inbox, with email management, autoresponders, and customer service agents built in.
