Lunchbreak AI vs StealthGPT

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors. Lunchbreak AI publishes a starting price ($10); StealthGPT does not. Only Lunchbreak AI has a free tier. Only StealthGPT ships a public API.

What our research says

Lunchbreak AI

Lunchbreak AI is built specifically around beating named AI detectors rather than generic paraphrasing, which is a narrower and more testable claim than most humanizer tools make. The obvious catch is that using it to submit AI-assisted work as your own can violate academic integrity policies regardless of whether it fools a detector.

Pros

  • Tests against six named detectors, not just one
  • Rewrites flagged passages instead of the whole document
  • Free plan lets you try it on a real essay before paying

Cons

  • No company name or location disclosed
  • Detector-beating claims can't be independently verified and detectors change over time

StealthGPT

The only thing here that competitors do not match is the developer surface — REST API, MCP server and n8n node — so this is the humanizer you pick if you are automating a content pipeline, not the one you pick to write an essay. Everything it sells is a bet on an arms race the detector vendors are also funding.

Pros

  • Genuine developer stack — documented API reference plus an MCP server, which rivals lack
  • Bundled detector lets you check before and after in one place
  • Chrome extension humanizes directly in any text field
  • Enterprise tier handles up to 20,000 words per run

Cons

  • Pricing page is behind a Vercel bot check, so prices cannot be compared without signing up
  • Daily request caps sit behind plans that market themselves as unlimited
  • Rewriting reliably flattens nuance and introduces awkward phrasing that needs an editing pass
  • Positioning around beating Turnitin invites institutional and reputational risk

Which one fits

Choose Lunchbreak AI if you need

  • Writers who draft with AI and need a natural-sounding final pass
  • Non-native English speakers smoothing AI-assisted drafts

Choose StealthGPT if you need

  • Content operations running bulk rewriting through an API or n8n workflow
  • Non-native English writers softening obviously templated LLM prose
  • Agencies that need humanizing inside an existing WordPress or Zapier stack
