Radarkit vs Semrush (2026): which should you pick?

Pick Radarkit if

• Fits if you run a local business and want to see which rivals AI recommends in your city
• Works for online shops tracking their products in AI shopping answers

Look elsewhere if

• Tight if you start on Lite: 15 prompts re-scanned every 72 hours, with no extra seats
• Pricey if you need daily scans, which start at Growth for $79 a month
• Skip it if you need Claude or Grok, as neither is among its six engines
• Watch out: state and city level tracking of your other prompts, and SSO, are on the custom-priced Enterprise plan
• Watch out: content articles and outreach credits are capped each month, and there's no yearly billing

Pick Semrush if

• Fits if you want research, rank tracking and audits in one account and can pay $117.33 a month or more
• Works for agencies that need keyword data for many countries and compare client sites with competitors

Look elsewhere if

• Pricey if you're one person with one site, at $117.33 a month even yearly, and the trial checks your card with a small charge
• Tight if your team is more than just you, since every extra user is from $45 a month
• Skip it if AI answer tracking is the point, as the SEO plan leaves it out and Starter is $165.17 a month
• Watch out: the API and share of voice need the custom-priced Advanced plan, and scheduled PDF reports are $10 to $20 a month extra
• Watch out: local, content, social and ad tools are separate toolkits with their own prices, and the free plan allows 10 reports a day

Radarkit

• Lite re-scans prompts only every 72 hours; daily scans start at Growth for $79 a month.

Radarkit

Tracking through real chat interfaces

Opens ChatGPT, Copilot, Gemini, Perplexity, Google AI Mode and AI Overviews as a customer would, from 50+ locations, instead of calling their APIs.

Local Radar

Runs prompts from a residential IP in a chosen city to show which local businesses AI recommends, with rank, rating and competitors.

Shopping and Ads Radar

Captures AI shopping carousels with each product's position, price, rating and store, and shows who is buying ads on the same prompts.

AI agents

A content agent drafts articles and optimizations, outreach and Reddit agents share monthly action credits, and a chat agent answers messages.

Traffic and Search Console

Connects Google Search Console and Google Analytics to report visits referred by AI assistants.

Client portal, reports and MCP

A client portal, branded PDF reports, full history, and MCP and API access for Claude, Cursor and other tools on every plan.

Semrush

Keyword research

Look up search volume, difficulty and intent from a database Semrush puts at 29 billion keywords across 142 country databases.

Competitor and backlink analysis

See which keywords and pages bring a rival site its traffic, and inspect any domain's backlink profile.

Position Tracking

Track daily rankings for 500 to 5,000+ keywords depending on the plan; Pro+ adds tracking by location and device.

Site Audit

Crawl your sites for technical SEO problems. From the Starter plan the audit also checks how ready a site is for AI search.

AI visibility tracking

Starter and above track daily whether set prompts in AI chat tools mention your brand, with sentiment monitoring. The SEO plan has none of this.

MCP and API access

Starter and above can query Semrush data from AI assistants through MCP; the API itself comes with the Advanced plan.
