When using Voiceflow’s web chat widget, you control chat persistence (how conversations are remembered) directly within the JavaScript snippet - not through the Voiceflow UI. This allows for more flexibility based on how you want your users' conversations to persist across sessions and browser tabs. ## What is chat persistence? Chat persistence determines whether users will return to an ongoing conversation or start fresh when they reload a page, open a new tab, or come back later. You can choose between different persistence strategies to match your desired user experience. ## How to configure persistence To set your preferred persistence behavior, add the persistence property inside the assistant object in your webchat snippet: JavaScript ``` window.voiceflow.chat.load({ verify: { projectID: 'your-project-id' }, url: 'your-runtime-url', versionID: 'production', assistant: { persistence: 'localStorage' // Set your preferred persistence option here } }); ``` Voiceflow supports three persistence options: `localStorage`, `sessionStorage`, and `memory`. | Option | Behavior | | --- | --- | | `'localStorage'` | **Default.** Conversations persist across page reloads and browser sessions. Useful for returning users. | | `'sessionStorage'` | Conversations persist across page reloads within a single browser session, but reset when all tabs are closed. | | `'memory'` | Conversations reset on every page reload or new tab. Best for ephemeral or private sessions. | Updated 6 months ago --- [Setting the version and runtime URL](/docs/custom-configurations)[Passing custom variables into web chat](/docs/customization-configuration) Ask AI * [Table of Contents](#) * + [What is chat persistence?](#what-is-chat-persistence) + [How to configure persistence](#how-to-configure-persistence)
