When the stack builder picks it
The builder reads each job's rules from the top and takes the first step whose conditions hold and whose plan fits the money left. Gemini is named in these steps:
- Copywriting, step 2 of 3, when less than $20 is left for it: the free plan; the step also names ChatGPT and Claude, and the best score takes it.
- Copywriting, step 3 of 3, otherwise: Google AI Pro ($19.99/mo); the step also names ChatGPT, Claude, Copy.ai and Jasper, and the best score takes it.
- Writing polish, step 3 of 3, otherwise: Google AI Pro ($19.99/mo); the step also names Grammarly, ChatGPT, Claude and QuillBot, and the best score takes it.
- Documents, step 2 of 3, when less than $20 is left for it: the free plan; the step also names ChatGPT and Claude, and the best score takes it.
- Documents, step 3 of 3, otherwise: Google AI Pro ($19.99/mo); the step also names Claude and ChatGPT, and the best score takes it.
The rules are public in stack-rules.json, and how the stack builder scores explains the tie-break.
