What our research says

Profound

Profound is the enterprise end of AI-visibility measurement: it covers more answer engines than most rivals, adds crawler analytics and ChatGPT Shopping that the cheaper trackers lack, and has the funding and customer list to still exist next year. The price is the reason to hesitate - there is no published figure, the free trial is seven days of fifty prompts, and the self-serve agency plan exists only as a line in the FAQ. Mid-market teams will get most of the signal from a tracker with a public price; brands with real budget and a procurement team are the audience here.

Pros

  • Tracks up to nine answer engines, including AI Overviews, Copilot and DeepSeek, not just ChatGPT
  • Agent Analytics shows which AI crawlers visit and cite the site, a layer most trackers skip
  • Prompt Volumes estimates real user questions rather than relying on your own prompt list
  • SOC 2 Type II, SSO and an API, so it passes enterprise review

Cons

  • No published price; the only listed plans are a free trial and a custom Enterprise contract
  • Trial is 7 days, 50 prompts and three engines, with no exports or history
  • No legal entity, address or terms page found on the site
  • The agency plan is named in the FAQ but not in the plan table

Writesonic

This is not the AI copywriter the catalogs still describe — it is a GEO tracking suite priced like one, and at $79 to start you are paying enterprise-monitoring money for a three-engine view of your own brand.

Pros

  • Daily prompt and answer tracking is the core of the product, not a bolt-on dashboard
  • Site audits, content generation and publishing sit in the same tool as the monitoring
  • A genuine free tier still exists, with no card required

Cons

  • Starter watches three engines out of ten; the interesting ones are all Enterprise
  • Month-to-month costs about 25% more than the advertised annual rate
  • The old writing-tool positioning is gone, so most third-party reviews describe a different product
  • Prompt and article caps are daily and monthly, so a burst of work stalls until the counter resets

Which one fits

Choose Profound if you need

  • Enterprise marketing teams that need AI-answer share of voice across many engines with exports and an API
  • Retail brands that want SKU-level visibility inside ChatGPT Shopping
  • Agencies managing several clients who can negotiate the workspace-based plan

Choose Writesonic if you need

  • Brands that already know they are losing citations inside ChatGPT and want it measured
  • Agencies reporting AI-answer share of voice to clients month over month
  • Teams that want prompt tracking and article production billed on one invoice
