Wren AI

What it is for

Wren AI is a GenBI desk on your warehouse: you model business meaning, then ask a question and it writes the SQL, runs it, and charts the answer. Use it when the job is natural-language analytics with a context layer you can edit, not when you need a $20 chat seat.

What makes it unique: the cover is the official Canner/WrenAI GitHub file list — wren-ui/, docs/, examples/jaffle, About “governed text-to-SQL” — not a pricing card.

Key features

• Home Ask — type a business question; Wren retrieves context, writes SQL, and returns a table plus chart (docs; official Cloud walkthrough). One ask. Agentic vs Classic, and follow-up turns, are modes of this, not five products.
• Modeling / MDL — the ER canvas names tables, columns, relationships, and calculations so the model sees business meaning, not raw schema (Introduction). Authoring, not a question.
• Knowledge pins — glossary, instructions, metrics, and SQL pairs you pin so a later ask reuses the same definition (official “Context Layer” walkthrough). A rule, not a one-off prompt.
• Embedded API + MCP — /api/v1/ask, generate-SQL, and an MCP server so an agent calls the same engine without the Home composer (API; pricing). A programmatic door, not the UI.
• OSS local stack — Docker / CLI GenBI on your machine with no Cloud credit meter (OSS). A deploy, not a Cloud seat. Enterprise Plus (air-gap, concurrent sessions) is the paid SKU of this.

Spreadsheets, dashboards, and GenBI Apps are outputs of Ask (they burn extra credits). gpt-5.6-luna / terra / sol are SKU. The Python/JS clients are install.

Who it's for

Best fit: data teams who will spend the 7-day Cloud trial, then pay Essential Cloud at $179/month billed annually (13,200 credits/year) instead of buying a per-seat BI copilot.

Pricing

Verified 2026-10-22 (Asia/Shanghai) from getwren.ai/pricing and Billing & Credits. Cloud is credits. Extra credits are $0.10 each. There is no named-user seat.

• Cloud trial — 7 days. Card required on the public page; cancel before it ends.
• Essential Cloud — $179/month, billed annually. 13,200 annual credits (about 3,000 questions/month on gpt-5.6-luna at their example profile). Unlimited members and projects. Embedded API + MCP. Basic RBAC.
• Enterprise Cloud — $559/month, billed annually. 24,000 annual credits. RLS/CLS, audit, LDAP/AD/OIDC, evaluation + thread tracing, priority support.
• Overage — unused Cloud credits roll over up to 2× the monthly allowance on monthly billing; annual credits reset each cycle. Extra credits $0.10. 20 free monthly credits expire at month-end and do not roll.
• Enterprise Plus (self-host) — quoted. Licensed by concurrent sessions (about 5 active users per session), not credits. Air-gap / on-prem. SSO + SCIM.
• OSS — $0 license for the public GenBI stack. You bring the model key and the warehouse.

Web credits are per 1,000,000 tokens (example: gpt-5.6-luna short input 2.8 credits / cached 0.28 / output 16.8). Failed actions are free. Confirm checkout; taxes follow your location.

Limitations / costs

• $179 is billed annually on the public card. Confirm the monthly toggle at checkout before you treat it as a month-to-month seat.
• Most tokens are context Wren sends, not your question. A “cheap” ask can still be 257K tokens.
• OSS is not Enterprise Plus. Air-gap, SCIM, and session licensing are the paid self-host SKU.
• A warehouse copilot, not a spreadsheet seat. For a notebook that talks to files see Julius. For a spreadsheet with AI see Rows.

Alternatives

• Julius — a hosted data notebook when the source is a file, not a modeled warehouse.
• Rows — an AI spreadsheet when you want cells, not a semantic layer.
• Quadratic — a Python/SQL grid when you will write the query yourself.
