Fresh AI angles for X posts and replies, in your voice.

Only text you highlight when you use ✦ Engage, plus the visible post or reply around that selection. We do not scroll timelines, study accounts, run server-side scrapers, or store your X password.

Signals you save via ✦ Engage → Save to Signals, stored locally on your device. Create can turn them into posts so your drafts trace back to real reading, not blank AI output.

Cloud ($12/mo or $69/yr) includes 300 hosted AI credits per month, no API key setup. You can also add your own API keys in Settings anytime: as fallback when credits run out, or as your preferred path. During the trial, use 30 Cloud credits or your own key for unlimited drafts.

Add your API key in Settings to keep drafting (BYOK fallback), buy a +100 credit top-up in Account & plan, or wait for credits to reset at the next billing month.

Same Cloud features and 300 credits per month either way. Yearly is $69 (about 52% less than twelve monthly payments).

No. GrowthX drafts replies and posts. You review, edit, then Copy or tap Fill to insert into an open composer. You send or publish yourself. Human-in-the-loop is non-negotiable.

AI slop is generic text pasted without reading the post. GrowthX is meant to work the other way: read first, add your take and what your work can offer, then use AI for reply angles. Blind copy-paste skips the part that matters.

Open Account and plan in the extension side panel → Manage subscription (Stripe customer portal). Cancel anytime; access continues until the end of the billing period.

During the 7-day trial you can cancel with no charge. After a paid period starts, we do not offer refunds, but you can cancel so the next period does not renew. See our terms for details.

Signals, brand kit, drafts, and workspace settings stay in chrome.storage.local on your device. Account email and subscription status are stored in our billing backend (Supabase + Stripe).
