The best product feedback usually arrives as a half-finished sentence. Your job is to hear the problem hiding inside it.
A focused Chrome extension for X
XReplyGen
Turn the post in front of you into a short, relevant reply that still sounds like you. Pick a draft, edit it, and send only when it feels right.
Appears in the composer. Disappears after insertion. Never presses Post for you.
Replying to @mayabuilds
Post your reply
Exactly. The phrasing is messy, but the friction is usually very specific.
Workflow
From blank reply box to something worth saying.
Every step stays with you: read, draft, edit, send.
Open a reply or quote
XReplyGen reads the visible post only after you enter the composer. It stays out of the timeline while you browse.
Generate, or ask for another
Choose a voice, generate a concise draft, and use Another one when the first angle is not yours.
Make it yours
The selected draft goes into X and the panel closes. Edit freely; the final wording and Post button stay yours.

Reply quality
Useful beats polished.
XReplyGen is tuned for concrete details, casual rhythm, and a point of view. The goal is a reply you can own after one small edit, not an AI-written mini essay.
Pro · Contextual product mention
Mention your product only when it belongs in the conversation.
Turn it on when you want XReplyGen to consider your product as part of a useful reply. A relevance gate checks the post first; when the fit is weak or the subject is sensitive, the draft stays product-free.
Normal reply
That half-finished sentence is usually the useful part. The exact friction is hiding in the wording.
Relevant product mention
I’m building XReplyGen around this exact gap: keeping the context before polishing the sentence.
This is a guardrail, not a ban-proof guarantee. You review every draft and remain responsible for any commercial disclosure required in your region.

Questions
Before you add it to Chrome.
Does XReplyGen post automatically?+−
No. It only inserts a draft into the X composer. You review, edit, and press Post yourself.
Do I need my own API key?+−
Free accepts any HTTPS OpenAI-compatible chat API key, not only a Volcengine key. Your key stays in Chrome extension storage and is sent only to the provider you select. Pro uses XReplyGen managed generation instead, so no model key is required in the extension.
Which model is fastest?+−
For Free, speed depends on the provider and model you bring; a fast non-thinking chat model usually feels best. Pro uses the managed XReplyGen path, tuned to keep X reply generation fast and context-aware without provider configuration.
What does Pro unlock?+−
No-key managed generation, two candidates, a path tuned for faster and more on-topic X drafts, personal style instructions, past-reply samples, and optional contextual product mentions for one connected account.
Does product mention mode keep my account safe?+−
It reduces obvious spam patterns by requiring direct relevance, transparent ownership wording, manual review, and no automatic posting. It cannot guarantee account safety: repeated unsolicited replies, irrelevant promotion, or missing commercial disclosure can still violate X rules or local law.
