Use a SynaBot assistant to produce the thinking, then move the output into Metaprompt for execution. Every SynaBot assistant is free to try on the Lite plan.

• Content Creator (ZARA) — drafts the copy, captions and campaign angles you'll run through Metaprompt.
• Business Planner (VIKRAM) — decides whether Metaprompt belongs in your stack and what it should replace.
• Project Manager (PACE) — turns the rollout of Metaprompt into owned, dated tasks.
