The short version

  • Only Slimchat has a free tier, so it costs nothing to try first.
  • Each has a real cost: Slimchat the vendor's own homepage as captured by the Internet Archive on 19 August 2018 (via Novosi, LLC) shows SlimChat was still pre-release at that date, offering an email signup for '3 months FREE' with an 'Expected release: summer 2018' notice and a $15 incentive to test a tour version; combined with the live site now serving a mismatched Squarespace certificate, this indicates the product likely never reached a stable commercial release; Superhuman high pricing compared to free alternatives like Gmail
  • They diverge on capability: Slimchat covers Live chat widget, Superhuman covers Blazing fast performance.
  • Prices and features above were last checked on 30 August 2026.
