TrendRadar – AI auto-commenter to grow on X

Hacker News

Hello Hacker News, I’m a solo indie hacker building in public. Over the last few days I built *TrendRadar*, an AI tool that automatically finds trending posts on X (Twitter) within topics you care about and writes comments in your voice. You choose the tone and sentiment, and the system handles the rest – even controversial angles. Some highlights: - *Single‑click authentication:* Connect your X account via the official API. No scraping or grey‑area methods – TrendRadar uses an approved X/Twitter application and is fully compliant with their terms of service (FAQ on the site explains this). - *Personalised auto‑comments:* You can tweak the level of controversy, review/edit comments before posting, and set custom prompts so the comments match your brand or personality. - *Real‑time trend detection:* The tool monitors your chosen topics and jumps on trending conversations 24/7 so you don’t miss out. - *Analytics dashboard:* See impressions, follower growth, engagement rate and more in a single panel. I launched it on my own account three days ago and saw impressions jump to ~40k and my follower count increase by ~50%. There’s a free Starter plan (3 auto‑comments per day) and an Early‑Bird Pro plan for early adopters. I’d love feedback from the HN community. You can try it here: * https://trendradar.app** . (If you do sign up, the promo code `EARLYBIRD` will apply a discount to the paid plan – there are 100 codes available.) Thanks for checking it out!
