The record

Purpose: OpenMailBot describes itself as an open-source AI layer for email tools that analyzes email threads across Gmail, Outlook, and Slack.
Inbox chat: Its chatbot can answer questions using emails, drafts, attachments, PDFs, and documents.
Summaries and drafts: It summarizes email threads and drafts replies that can retrieve information from attachments.
Writing and labels: It learns writing tone from past sent emails and automatically labels incoming messages with personalized categories.
Email access: The site says users connect an inbox with Google or Microsoft OAuth.
AI and storage options: The site lists OpenAI, Anthropic, Gemini, Mistral, Cohere, Ollama, ChromaDB, Pinecone, and Qdrant as options to mix and match.
Self-hosting: OpenMailBot says it can run on a user's servers, VPC, or Kubernetes, and describes a zero-config mode using ChromaDB and Ollama.
Privacy claims: The maker says emails stay on the user's server and that the service does not see them; the page presents these as product privacy claims.
Tenant isolation: The site describes vector namespaces per tenant and user, and a Neo4j contact graph with GDPR Article 17 delete.
Integrations: The site lists Slack ingestion and says ongoing integrations include Teams, Notion, Jira, and Linear.
Setup requirements: The quick setup documentation lists Node.js 18+, Python 3.8+, Git, and Bash on Linux or macOS, or Git Bash on Windows.
Setup process: The setup script installs dependencies, sets up MongoDB, configures environment files, starts backend, agent, and frontend services, and can open a browser to localhost:5173.
Support: The Community plan includes community support on GitHub; Enterprise lists a solution architect on-call.
Intended users: The site describes the product as built for self-hosters and enterprise teams and highlights lawyers, accountants, businesses, privacy-conscious people, and developers or DevOps.
