RYPL focuses on sales-first, human-like replies for Facebook comments. It reads per-user context, keeps your brand tone, and blends LLMs with guardrails (spam/negativity filters, auto-like, escalation rules) to convert comment threads into real conversations at low latency and without sounding like a bot.

Rypl's answer:
SMBs and growth teams with active Facebook Pages e-commerce brands, local services, restaurants, creators, and agencies that need consistent, on-brand replies to capture leads from comments.
Diffyn's answer
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
Rypl's answer:
RYPL was built after seeing “lead leakage” in Facebook comments/DMs: warm buyers asked questions, no one answered in time, and sales died. The goal is a fast, on-brand AI that treats every comment like a sales touch without feeling like automation.
