Hashtag Expert vs Keyword Tool

Hashtag Expert uses algorithms and AI to suggest personalized hashtag groups from a database of millions of hashtags. Users enter a base hashtag, choose a generation algorithm, and can browse 35 categories, including Art, Yoga, and Small Businesses. Favorite hashtags can be saved in collections, and copy settings let users adjust formatting and separators. A tutorial says each group can contain up to 30 hashtags; bulk generation is not available. The site lists daily trending hashtags for Instagram, TikTok, Facebook, Twitter, Pinterest, YouTube, and LinkedIn. Its App Store description also lists AI captions, suggested posting times, curated event hashtags, analytics, and a members-only community. Facebook or Instagram linking is optional and is described as a way to get more personalized suggestions and insights. The service is available as an extension, iOS and macOS apps, and a web app that works in desktop and phone browsers. Premium Yearly costs $89.99 a year, with a 3-day free trial.

Keyword Tool generates long-tail keyword suggestions from autocomplete when given a seed term. It supports keyword and competitor research across 16 platforms, including Google, YouTube, Bing, Amazon, TikTok, Reddit, Pinterest and Google Trends. The free tool works without an account and can return 750+ Google autocomplete keywords. Paid plans add search volume, cost per click, competition scores, device breakdown and historical trends; they also support search-volume enrichment for up to 1,000 keywords per request, with daily capacity depending on the plan. Access includes the web interface, API and MCP, and Claude, Cursor and ChatGPT are named as compatible assistants. Google coverage includes 190+ countries, 68,000+ locations and 50+ languages. The site says Google and Bing metrics come from planner ecosystems, while volumes for other platforms are modeled estimates based on clickstream signals. Web, API and MCP share a daily request pool, and available MCP tools can vary by endpoint, plan and rollout status. Paid plans start at $68 a month. There is no free trial; the pricing FAQ lists a 30-day money-back guarantee for paid plans.
