Sent2X.
Built for X growth.

Sent2X is an AI growth engine for X. Discovery finds threads in your niche, Buyers finds the people who would buy your product, the extension puts an AI pen, voice input, and translate in every x.com reply box, Open & draft opens a ready composer from a Discover card, the Replies inbox drafts answers to your mentions, Planner writes a week of posts, overnight draft agents draft overnight, and Home shows what actually pulled followers. Scheduling is one piece of that loop.

Schedulers only handle the posting step. Sent2X handles finding what to reply to, finding people who would buy, drafting the replies, planning next week's content, and telling you what's working — the actions that compound reach. Every module runs off a live cached database, so pages respond in under 6 seconds instead of the 30–60 seconds you'd wait on tools that re-fetch from X on every click.

AI reads your account, identifies 7–8 topic channels that match your niche, and surfaces roughly 30 high-engagement posts every day — the threads where an early reply gets you seen by the right people. Free plan includes 30 searches/month; Pro 20/day; Max 30/day.

Every reply to your posts, consolidated in one place, with an AI-drafted response ready to send. Passive @-mentions turn into real conversations without you refreshing X. AI reply + remix quota: 5/day on Free, 150/day on Pro, 400/day on Max.

Yes. Generate an API key in Settings. Claude Code runs sent2x create --at. Buffer shipped a GraphQL CLI in May 2026 for multi-network queues. Typefully documents a REST API (5 May 2026), not an official CLI. Sent2X's CLI is scoped to one X account plus Discovery, Buyers, and the reply box.

Free ($0, 10 posts/month, 30 AI replies + remixes/month including voice and translate, 30 Discovery/month, 30 Planner/month, 2 Buyer analyses/month, Monday weekly report). Every plan includes the x.com reply box (pen, voice → English, translate), Open & draft, and the Replies inbox. Pro ($39/month, 500 posts, 150 AI replies + remixes/day, 20 Discovery/day, 150 Planner/month, 20 Buyers/month, 1 overnight draft agent + 3 extra Run now/day, weekday morning digest + weekly). Max ($59/month, 750 posts, 400 AI replies + remixes/day, 30 Discovery/day, 400 Planner/month, 50 Buyers/month, 5 overnight draft agents + 10 extra Run now/day, weekday morning digest + weekly).

A post agent monitors your Discovery feeds every night, picks the top-performing posts from your niche, and drafts new posts in your voice based on what's working — without copying anyone's words. It borrows the structure, not the sentences, and not the author's voice. You review and approve before anything goes into your queue. Pro includes 1 agent; Max includes 5.

Three Sent2X buttons sit next to Reply: automations (saved instructions), the AI pen (tone + a draft), and voice input (speak any language, land English). Translate is a module on the automations list — it rewrites the draft already in the box. Voice and translate each spend one AI reply, same pool as the pen. Open & draft is the one-click path from a Discover card to that composer.

Yes. Sent2X is built for X growth and includes scheduling: queue posts, batch-import a week of content, and auto-publish to X. It also finds threads to reply to, finds people who look like buyers (Buyers), drafts those replies, and exposes a CLI so Claude Code can schedule posts. Free plan includes 10 scheduled posts per month.

Buyers finds people on X who look like buyers for your product. Paste a homepage — we search X, group accounts into watch lists (looking for a tool, competitor complaints, indie hackers, tech creators, side-project founders), and seed reply templates. Import the list, then open Discover to see their new posts. Each successful analysis spends one Buyers turn: Free 2/month, Pro 20/month, Max 50/month. Planner is a separate pool.

For X growth, yes. Typefully Free is 15 posts a month on one social set and stays a writing-first editor for X, LinkedIn, Threads, Bluesky, and Mastodon. Sent2X is X-only: Discovery, Buyers (Free 2 / Pro 20 / Max 50 analyses a month), a reply box on x.com, and node bin/sent2x create --at. Stay on Typefully if the editor is the product. Typefully alternative for X

For X-only growth, yes. Buffer Essentials is $5 per channel yearly or $6 monthly for a multi-network queue, and Buffer shipped a GraphQL CLI in May 2026. Sent2X is $0 / $39 / $59 for one X account plus Buyers and the reply box. Keep Buffer if Instagram or TikTok share the calendar. Buffer alternative for X growth

Install from the Chrome Web Store, sign in with X on sent2x.com, then open or refresh x.com — the panel docks on the right. Chrome updates store installs on its own; the round Reload button in chrome://extensions is only for developer (unpacked) installs.

Add an email in Settings or from Getting started. Free gets a Monday weekly growth report. Pro and Max also get a weekday morning digest. One toggle turns all report mail off. Sign-in stays X-only — the address is for reports, not a second login.
