Clavio vs Vanna AI

Clavio is a web-based AI data analysis platform that turns plain-English questions about business data into analysis, charts, explanations, and reports. Its analysis tools include profiling, statistical tests, regression, clustering, anomaly detection, causal methods, forecasting, sentiment analysis, and multi-step agent investigations. Users can inspect source fields, transformations, assumptions, diagnostics, and generated code associated with results. Listed data sources include PostgreSQL, MySQL, BigQuery, Snowflake, Redshift, SQL Server, SQLite, MongoDB, ClickHouse, and Supabase, as well as APIs, cloud storage, spreadsheets, files, and selected public datasets. Database queries are limited to SELECT, WITH, or EXPLAIN, with default results capped at 10,000 rows and 5 MiB. CSV and Excel uploads are parsed in the browser; Clavio says file contents do not touch its server. It also says AI providers receive schema, column statistics, and the question, not data rows. Sign-in uses passwordless email, with optional TOTP two-factor authentication. Owners and admins can review and export an organization-scoped append-only audit log. Free access is available; Pro costs $19 a month and Team costs $49 per user per month.

Vanna AI is an open-source, user-aware agent framework that connects language models to databases. Agents can run SQL queries, generate charts, and call custom functionality through tools. Tool Memory records successful interactions and searches earlier queries and tool-use patterns when handling similar questions. Listed language-model options include Anthropic, OpenAI, Azure OpenAI, Gemini, and Ollama. Database integrations include SQLite, PostgreSQL, MySQL, MS SQL, Snowflake, and BigQuery; memory options include demo in-memory storage, ChromaDB, and Pinecone. Vanna can run through Vanna Cloud or by self-hosting, with FastAPI and Flask server choices. Documentation describes user-specific access controls and tool access groups. Explorer costs $50 a month for 20 questions per day, while Team costs $500 a month for 300. Enterprise pricing is custom, with unlimited questions and listed enterprise features. The security FAQ describes the premium backend as in development/demo stage and lists current limitations.
