Chrome Extension FAQ

Common questions about the OpenTweet Companion extension

Is the Chrome extension really free?
Yes. The OpenTweet Companion extension is completely free. It pairs with your OpenTweet account (which has a free 7-day trial), but the extension itself costs nothing to install and use.
Does the extension collect my data?
No. The extension only reads publicly available data on X profile pages when you choose to analyze them. We do not track your browsing, sell data, or collect anything beyond what you explicitly request.
How accurate are the posting time recommendations?
The recommendations are based on actual engagement data from the profiles you analyze. The more accounts in your niche you analyze, the better the recommendations become. They reflect real patterns, not generic averages.
Does it work with the new X.com domain?
Yes. The extension works on both x.com and twitter.com. It automatically detects which domain you're on and activates accordingly.
Can I customize what counts as a viral post?
Yes. You can set custom thresholds for likes, retweets, replies, and views. This is useful because "viral" means different things in different niches — 100 likes might be viral in a niche community but normal in tech Twitter.
