What is Exploding Topics?
Exploding Topics uses machine learning to surface emerging trends, products and markets months before they peak. It is a trend-spotting database with a weekly newsletter and a Trends API, ideal for early market research. The catch: it shows topic-level trends — not the actual viral posts on each social network — and has no engagement tracking or team tools.
- Genuinely early trend detection (12-month forecasts)
- Affordable entry plan
- Trends API for automation
- Topic-level only — not per-network viral posts
- No engagement tracking or team workflow
- API is a costly add-on
Pricing: from ~$39/mo
What is Semrush?
Semrush is an all-in-one SEO and digital-marketing suite: keyword research, competitor analysis, rank tracking, site audits, plus content and (via add-ons) social tools. It is a powerhouse for search marketing and is sometimes compared to BuzzSumo for topic research. But its core is SEO and paid search, not discovering the viral posts trending across social networks, and the social features are add-ons rather than a real-time cross-network radar.
- Enormous keyword and competitor database
- Full SEO + content + PPC toolkit
- Topic research and content templates
- SEO-centric — social viral discovery is an add-on
- No editorial board or team workflow for content
- Add-ons push the price up fast
Pricing: from ~$139/mo
What is ViralHunt?
ViralHunt is a viral-content discovery platform that tracks the top-performing posts across 8+ networks — TikTok, Instagram, Facebook, Pinterest, Reddit, X, RSS, Quora and Tumblr — in real time. Beyond discovery, it turns trends into a team workflow with an editorial Kanban board, an AI content studio and built-in team chat — and now schedules and auto-publishes finished posts to 8 social networks, with separate brand/client projects. So a whole team can find, create and publish content in one place instead of stacking a discovery tool, a workflow tool and a scheduler.
- Tracks viral posts across 8+ networks in one dashboard
- Editorial board, AI studio and team chat built in — no extra tools
- Schedules & auto-publishes to 8 networks, with multi-brand projects
- Affordable, a free trial, plus a REST API for AI agents
- Not a dedicated enterprise listening/analytics suite
- Younger brand than the incumbents
Pricing: from $29/mo

- Exploding Topics — best for spotting rising topics and market trends early.
- Semrush — best for SEO and SEM teams doing keyword, competitor and content research.
- ViralHunt — best if you want to discover viral content across 8+ networks and turn it into content as a team.
