brainX in action: AI reply suggestions on X

$ brainX --help

// features

--context-aware
Replies that earn attention

brainX reads the post before generating anything. The result is a reply that fits the thread and builds credibility with your audience.

--multi-reply
Scale your presence

Reply to multiple posts at once, or let brainX scan every post visible in your feed and queue suggestions to stay visible without burning hours.

--draft-mode
Post when timing is right

Save any generated reply as a draft and come back when the moment is right. Maintain a consistent distribution rhythm without rushing.

--customize
Your voice, your channel

Pick from built-in tones or write your own from scratch. Swap the underlying chat model so every reply sounds like you, not a bot.

--use-right-model
Use the latest ChatGPT model

Try different models with your persona. Use one which gives the best results

--limit-batch-size
Cap at 20 replies per run

Generating more than 20 replies at once tends to degrade quality and burns through tokens fast. Run smaller batches for tighter, more useful suggestions.

--vet-before-posting
Always review before you post

AI replies are a starting point, not a final draft. Read each suggestion, adjust the tone or wording if needed, and make sure it sounds like you before hitting Post.

--custom-tone
Build a custom tone for better replies

The more specific your tone instructions, the better the output. Describe your style, your audience, and what you want to avoid and brainX will follow it precisely.
