Hey Product Hunt š
I built ReplyForgeAI because I was tired of switching between X and multiple AI tabs just to write better replies.
Most AI writing tools lock users into subscriptions and store everything on their servers.
So I built a different approach:
ā Bring your own API key ā Use your favorite AI provider ā Everything runs client-side ā No accounts required ā No monthly subscription
ReplyForgeAI works directly inside X and helps you:
Generate smarter replies
Improve tweet drafts
Write faster with AI
Keep full control over your workflow
It currently supports OpenAI, Anthropic, Gemini, Grok, Perplexity, OpenRouter, Mistral, Groq, and DeepSeek.
Would love your feedback, feature ideas, and honest thoughts š
