## Where each ships

### Gemini-only stacks (1)

- [Indie SaaS (Gemini long-context)](https://aistack.sh/stack/indie-saas-gemini) — Different ergonomic from the Claude-led pair: instead of pasting individual files per turn, dump the entire repo into Gemini and let it reason across the whole graph. Claude takes over for tight, surgical edits; Gemini handles 'change auth across 14 files' moves.

### Perplexity-only stacks (3)

Perplexity replaces Feedly for one-writer research scale. Total spend stays under $25/mo until you have paid subs to give back 10% of.
- [Faceless YouTube](https://aistack.sh/stack/faceless-youtube) — An end-to-end faceless channel pipeline. Topic research, scripts in your voice, AI voiceover, generative B-roll, captions, upload. Start to finish in an afternoon.
- [Live trend research](https://aistack.sh/stack/live-trend-research) — The web's lag and the chat-LLM's training cutoff make 'what's happening this week' research painful. Grok pulls live X chatter, Perplexity grounds in cited sources, Claude turns the two streams into a 5-bullet brief you can hand a colleague. 30-min weekly habit replaces 4 hours of tab-switching.
