The premise
Below a certain prompt count and team size, a versioned file beats a SaaS. Above it, you need a real platform.
What AI does well here
- Track prompt versions and authorship
- Run A/B tests on prompts
- Surface drift in outputs over time
What AI cannot do
- Decide what 'better' means for you
- Replace human review of bad outputs
- Eliminate the work of curating eval sets
