What it does

Create a custom AI agent tailored to assist with developing plots and characters for a specific book series.

What it does

The user creates a specialized chatbot configured with detailed instructions about their fictional universe, including themes like dark sci-fi romance. They upload existing books as a knowledge base so the assistant can recall specific details and provide consistent creative suggestions for plotlines and character development.

Example output

Understood. I have locked in the core lore, character profiles, and tonal benchmarks for your Neo-Kyoto series.

Here is my confirmation of the foundational elements:

  • Theme: Love as a dangerous glitch; emotions as taxable contraband.
  • Setting: Neo-Kyoto, a dystopian neural network where the State AI monitors and taxes emotional output.

https://news.ycombinator.com/item?id=38772923 (user_report)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.
