Beginning in the Q2 2026 stable release, self-hosted instances using the multiplayer feature must set the LICENSE_KEY environment variable on the multiplayer service container. While this environment variable is not yet required, Retool recommends setting it now to avoid any service interruptions.

Assist now supports the ability to create and edit multipage apps. Previously, Assist could only work with one page at a time.

Assist can now:

• Plan and build a multipage app from scratch.
• Create, edit, and rename pages.
• Move queries and code between global and page scopes.
• Create globally-scoped frames and components, such as Navigation, to help users move between pages.
• Identify and correct page scope errors.

While Assist is generating, navigating between pages is disabled to prevent errors.

Retool now supports two modes for prompting with Assist: Ask and Build. Use Ask as a safe, read-only way to understand and debug your app without adding or changing components or logic, and Build when you’re ready for Assist to make edits.

• Ask mode: Assist replies with explanations, suggestions, or debugging help. When in Ask mode, Assist cannot modify your app.
• Build mode: Assist can create and edit components, queries, and logic in response to your prompt.

Both modes use the same understanding of your app, your data, Retool features, and documentation.

Assist defaults to using Build mode. You can switch between modes at any time.

Assist can now automatically summarize long threads. The amount of information sent to the AI provider (the context window) increases as you build. Instead of sending your full message history to the AI provider with every request, Retool now regularly compacts the thread and sends the conversation summary along with any following messages. This improvement keeps the context window within the required limits, reducing the likelihood of errors and preventing interruptions when prompting with Assist.

Thread summarization can occur either during or after app generation.

Assist can now more reliably explore large or under-documented SQL database schemas without exceeding LLM context windows. These changes enable Assist to generate higher quality SQL queries for your apps and reduce the likelihood of SQL-related errors.

Customers with simple schemas now benefit from richer context retrieved through exploratory queries, while large enterprises can rely on Assist to navigate massive data lakes.

Retool improved Assist's ability to reason about and plan layout changes for large and complex apps. This change has the following impacts:

• Improves the quality of layouts when editing medium to large apps. Assist is now better at formatting the spacing and alignment of components.
• Improves latency when making large edits to UI layout. For example, one layout change that previously took 5 minutes now takes under 1.5 minutes.
• Improves support for adding header frames.

Retool now supports Azure OpenAI for use with Assist. Admins on the Enterprise plan can configure Assist to use Azure OpenAI as the single model provider for Assist-powered interactions.

Retool designed Assist to use two AI providers by default: OpenAI and Anthropic. Using both providers enables Assist to optimize for speed and quality. However, some customers may need to consolidate AI services with a single provider. To accommodate these customers, Enterprise organizations can configure Assist to work with a single provider.

Retool now supports Amazon Bedrock for use with Assist. Admins on the Enterprise plan can configure Assist to use Amazon Bedrock as the single model provider for Assist-powered interactions.

Retool released some updates and improvements to the Assist experience:

• You can now prompt Assist to write a README for your app. When you're editing an existing app, Assist can also use information from existing READMEs to learn about the app context and improve the quality of changes.
• Assist automatically names apps. When you use Assist to create a new app from a blank canvas, Assist provides a descriptive name.

These changes are live on Retool Cloud. Refer to the edge release notes for information about what features are available to self-hosted organizations.

Retool is excited to announce Assist, your AI-powered partner for app development. Prompt Assist with natural language directly from the app IDE to generate apps, make changes to existing apps, and ask questions about Retool.

Assist can:

• Generate full-stack apps from a prompt using your live production data. Retool scaffolds apps based on your real databases and resources.
• Respect all existing org policies by default—SSO, role-based access control, and data-level permissions. Apps remain secure and access-controlled without any manual configuration.
• Edit components, queries, and styles of your existing apps.
• Answer questions about an existing app, including about the purpose of the app and how it works. Assist can also answer questions about Retool in general.
• Deploy AI-generated apps to production without leaving Retool. Hosting, versioning, and monitoring are built-in for cloud and self-hosted deployments.
