# Social radar > Ask Radar what is happening now across the web, X and Reddit within a time window, and get a chat briefing that cites a source for every claim. Source: https://endless.okinawa/docs/radar **Social radar** searches the web, X and Reddit within a time window you choose and answers in a chat, with a link behind every claim. It saves nothing: no watchlists, charts or history. The conversation it starts is kept in [chat history](/docs/chat/history). ## Ask Radar something 1. Type a question, or select a trending topic under the composer to fill in a prompt you can edit. 2. Set the window in **"Real-time recency"**: **"Last 30 minutes"**, **"Last hour"**, **"Last 8 hours"**, **"Last 24 hours"** (default), **"Last 7 days"** or **"Last 30 days"**. 3. Optionally, under **"Sources"** in the same menu, turn off **Web**, **X** or **Reddit**. At least one stays on. 4. Send. A new chat opens with the briefing. Choosing **"Off"** in the recency menu turns it into an ordinary chat prompt. ## The briefing * Newest and most significant developments first, grouped by theme. * Every claim links to its source; unconfirmed claims are flagged. * If little happened in the window, it says so and doesn't widen the window. Ask for a longer one if you want. You can keep chatting from there, as in any [chat](/docs/chat). ## Trending topics Up to four topics, for the region your request comes from (there's no region picker). When there are no live trends, Radar shows suggested topics with a dashed outline. If trends failed to load, each says *"An error occurred while loading live trends - suggested topic, not live"*. ## Radar inside a chat Type `@radar` in any chat composer to add the same recency control. After you send, every later message in that chat searches the same window until you pick **"Off"**. This is remembered per chat in this browser only. See [mentions](/docs/chat/mentions). ## Other details * The Radar composer supports [dictation](/docs/transcripts/dictation) and dropping files to attach. * A half-written prompt is kept if you leave and come back. * A question asked on Endless's public trends pages before sign-up appears in the composer, not sent, because running it spends credits. * Radar is priced like any chat: the reply has its cost and each search is a paid step. A wide window across all sources costs more. See [credits and spending](/docs/concepts/credits-and-spending). * Radar can be turned off for a workspace, a team or one person. Then it's missing from the sidebar and its link opens the workspace home. See [feature availability](/docs/governance/feature-flags). ## Related * [Chat](/docs/chat) * [Social research](/docs/chat/social) * [Scheduled tasks](/docs/automate/scheduled-tasks): run the same briefing on a schedule.
