Retool AI

Retool is a platform for building internal business applications — admin panels, data dashboards, customer support tools, and operational workflows — by connecting directly to databases and APIs.

Retool has rebuilt its app builder from the ground up to be AI-native: instead of starting with a blank canvas, users describe the app they need and Retool generates a working version. The previous drag-and-drop builder still exists and is now called the classic app builder, and apps built with it continue to work. In October 2026 Retool also introduced an agent harness that aims to give every employee a governed agent inside Slack, Microsoft Teams, and Google Chat, with a company-controlled gateway enforcing limits on tools, data, and models. This agent harness is in early access only, gated behind a waitlist, and Retool has not published pricing for it.

Beyond the new builder, Retool AI lets teams embed LLM-powered components into apps: AI form completion, AI data summarization, AI chatbots within internal dashboards, and agentic workflows that chain multiple AI steps with human-in-the-loop approval gates. The platform connects to data sources including Postgres, MySQL, Snowflake, MongoDB, REST APIs, and GraphQL, and supports JavaScript and Python for custom logic, along with audit logs and role-based access control.

Retool's Free plan covers up to 5 users with unlimited web and mobile apps but is metered: 500 workflow runs per month, 5GB database capacity, 5GB file storage, 250 AI credits per month, and up to 20 agent hours per month. Paid plans split Builder seats (people who build apps) from cheaper Internal User seats (people who only use them). Team Builder seats cost $10 per user per month billed annually or $12 billed monthly, with 1,000 AI credits per month (750 base plus 250 bonus) and 5,000 workflow runs; Team Internal User seats cost $5 per user per month annually or $7 monthly. Business Builder seats cost $50 per user per month annually or $65 monthly, with 3,000 AI credits per month (1,500 base plus 1,500 bonus); Business Internal User seats cost $15 per user per month annually or $18 monthly, and external users are free up to 50, then tiered from $8-$10 per user. Enterprise pricing is custom, including 1,000 AI credits per builder plus 4,000 pooled credits. Retool Agents are billed separately by the hour at rates that vary by model, with a free allowance of up to 20 agent hours per month included across all tiers; agent execution pauses when those free hours run out until the account is upgraded.

Retool is optimized for internal tools — it is not suitable for building customer-facing production apps. Agent usage is billed hourly on top of per-seat costs, which can make total spend harder to predict for teams that use agents heavily, and the new agent harness is not yet generally available. The builder, even in its AI-native form, benefits from familiarity with data concepts (queries, transformations) for anything beyond the generated starting point.

Best suited for operations, product, and engineering teams at startups and enterprises who need to build custom internal tools on top of their existing data sources — particularly those adding AI-assisted workflows or company-wide agents to existing business operations.
