Tessio
What it is
Tessio is an IT service desk platform with an AI teammate called Tess. Tess can triage tickets, route them to teams, draft replies, summarize conversations, find similar tickets, and search the queue in natural language. Its knowledge base supports article revisions, and Tess can answer from articles with cited sources. Core service-desk tools include ticket queues, intake forms, workflows, SLAs, email-to-ticket, asset and device inventory, dashboards, custom reports, and a brandable requester portal. Tess connects to OpenAI and compatible endpoints, including Azure OpenAI, Ollama, LM Studio, vLLM, and local gateways. Community is self-hosted, AGPL-licensed, and deployable through Docker Compose, a single container, or Kubernetes; a hosted Cloud edition is also listed. Community costs nothing and includes five admin/agent seats, while requesters are unlimited and free across editions. The maker says self-hosted data goes only to the selected LLM endpoint, Tessio has no configured telemetry or phone-home behavior, personally identifiable information is redacted at the model boundary, and AI remains off until an LLM key is provided.
