X custom timelines: What users are saying about the new feature

Source: Mashable Tech

Overview

Social media app X rolled out a new custom timeline feature earlier this week, and so far, user reactions have been positive.

Feature Details

• The new feature is reminiscent of TweetDeck, which recently rebranded as X Pro.
• Using custom timelines, X users can create feeds for specific topics.
• The feature is powered by the xAI tool Grok (details) and is currently available to Premium subscribers on iOS devices. Android support is slated to arrive soon.

“It’s powered by Grok’s understanding of every post with the algorithm’s personalization — meaning every timeline is made just for you. And it works even better when it’s a topic you already engage with. This was a huge undertaking across many months, so we’re excited for you to take it for a spin,” — Nikita Bier, head of product at X.

X also released a short video demonstrating how the feature works.

User Feedback

• Podcaster Aakash Gupta noted that the update lets users create up to 75 custom timelines powered by Grok and speculated that the feature would provide xAI with a lot of new data for AI training.
• In general, X users were excited to try the feature, though some confusion is typical with new‑feature rollouts.

Specific Requests & Responses

• A user asked about a Catholicism‑focused custom feed. Bier replied:

  “Update your app. That’s the old experimental feature. We’re working on supporting religions in the next 2 weeks. We had it earlier, but the quality/content didn’t meet our bar yet.”

• When asked if it was possible to prevent topics from appearing in a feed, Bier pointed users to the snooze topics feature, which launched alongside custom feeds and is available now for iOS and web Premium users.

• Other comments requested specific topics such as Ukraine, manufacturing, Bitcoin, and memes.

Skeptical but Willing Users

• @syssignals: “Using it since morning, tbh it’s okay. I saw overlapping between AI, Software and Tech. Also seeing same content again and again on these timelines. I am still on my For you timeline. But hope this custom timeline will be mature as time goes by.”
• @Hoxygo: “Finally a way to separate tech from sports without building a whole new account. The real test is whether the algorithm respects the timeline boundaries instead of bleeding the main feed into it.”
