Lunchbreak AI vs StealthGPT

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

• −Detector-beating claims can't be independently verified and detectors change over time
• −The $10 headline is the annual rate; month-to-month Pro is $19.99
• −The 3-day trial needs a card up front

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
