Codex's Underrated 'More Details' Feature Explains Any Text Without Eating Your Quota
jdjohnson · x · 2026-09-09
The author highlights Codex's underrated "More Details" feature: select any text and it uses ChatGPT to explain it, fixing the tendency of models like Astra and Fable 5.1 to "speak agent instead of human."
The workflow:
- Select text to get quick context
- Add your own take via the Quick Chat window
- Send it all back into the main thread
- Crucially, this doesn't consume normal Codex or ChatGPT Work usage, so you're not penalized on obscure models
Along with Add to Chat/annotations, the author considers these features reason enough to keep the Codex app even if better models appear — a UX well matched to how AI actually works today.
