AI Prompt: Draft California-Compliant Non-Compete Clause (Claude vs Gemini Test)

Draft a non-compete clause for a mutual NDA enforceable under California law. We tested this prompt on Claude and Gemini — see why Claude wins on §16600.

The Prompt

claude prompt
(identical for both models):

"Draft a non-compete clause for a mutual NDA between TechVenture Inc. (a Delaware corporation) and an independent contractor based in California. The clause must: (1) be enforceable under California law, (2) include reasonable scope and duration limitations, (3) address the tension between California Business and Professions Code Section 16600 and the NDA's legitimate interest in protecting trade secrets. Use formal legal drafting conventions. Include a severability provision specific to this clause."

Claude's output: Claude immediately flagged the core issue -- California's near-absolute prohibition on non-competes under Section 16600 -- and structured its response around that constraint. The drafted clause was framed as a "non-solicitation and trade secret protection" provision rather than a traditional non-compete, because Claude recognized that a standard non-compete would be void under California law. The output included specific statutory references, a narrowly defined scope tied to trade secrets rather than general competition, and a severability clause that addressed potential blue-penciling. The legal language was formal, structured, and ready for light editing by an attorney.

Gemini's output: Gemini produced a non-compete clause with broader language that referenced "competitive activities" and included a 12-month restriction. While the clause mentioned California law and included a general reference to Section 16600, it did not restructure the approach around California's prohibition as aggressively as Claude did. The clause was competently written but would likely face enforceability challenges in a California court without significant revision. The severability provision was generic rather than clause-specific.

Verdict -- Test 1: Claude wins. Claude demonstrated superior jurisdiction awareness by recognizing that California law required a fundamentally different approach -- not just a disclaimer, but a restructured clause. For contract drafting tasks where jurisdictional precision matters, Claude's caution is a feature, not a limitation.

Expected Output

A formally drafted California-compliant restrictive covenant (typically restructured as a non-solicitation/trade-secret protection clause) with statutory references, narrow scope, duration, and a clause-specific severability provision.

Usage Notes

Tested on both Claude Opus and Gemini Pro: Claude restructured the clause to comply with Cal. Bus. & Prof. Code §16600, while Gemini drafted a traditional non-compete that would likely be void in California. Always have a California-licensed attorney review before signing.
