REPLY FORGE

\n\n

\n Generates strong replies without any AI API. For fact-backed replies, include a link to an allowed domain\n (Reuters/AP/.gov/grokipedia, etc.).
\n Note: x.com status links aren’t used for facts. Paste a trusted article link if you want sourced points.\n

\n\n

\n Use links for facts\n Only grokipedia.com\n Conservative voice\n

\n\n

\n \n Curated domains allowlist (comma-separated)\n We only fetch from these\n \n \n

\n If your post includes links on other domains, add them here (example: foxnews.com, wsj.com, etc.).\n

\n\n

PASTE POST TEXT

\n \n

Links inside the post are OK. If there are no usable links, we still generate an engaging reply.

\n\n

EXTRA LINK (OPTIONAL)

\n \n

Tip: if you paste an x.com status link here, it will be treated as context only, not a fact source.
