// FIELD NOTES · PRO TIPS
- ◆Autocomplete quality jumps when files have clear names and imports — Codeium reads context, so organized projects get better suggestions.
- ◆Use natural-language comments as prompts: write '// parse ISO date, return null on failure' and let the completion write the function.
- ◆Codeium Chat can explain unfamiliar code — highlight a gnarly function and ask 'what does this do' before refactoring legacy files.
- ◆Turn on the specific-language settings for your stack; disabling suggestions in markdown/config files cuts the noise dramatically.
- ◆In interviews for productivity: measure it for a week, and disable it when learning a new language — autocomplete short-circuits learning.

06 Frequently Asked Questions
Is Codeium really free?
Yes — individual autocomplete, chat, and search are free with unlimited usage, which is Codeium's main pitch against Copilot's subscription. Teams/enterprise tiers add security and admin features.
Codeium vs GitHub Copilot?
Quality is comparable for mainstream languages; Copilot has deeper GitHub/VS Code integration and the strongest brand, Codeium is free and supports more IDEs (including JetBrains, Vim, and web IDEs). Budget-sensitive devs start with Codeium.
Does Codeium train on my code?
Codeium states individual users' code is not used to train models and offers on-prem/self-hosted options for enterprises with strict policies. Review current terms if you work on proprietary code.
