Grow on X. On autopilot.
Every day, AI finds the high-signal threads worth replying to, drafts your replies, and plans next week's posts — so growing on X becomes a loop that runs itself, not a daily grind.

Shipped my first paid feature today. The dopamine hit of that first Stripe notification is unreal.
Congrats! That first Stripe ping is core memory material. What was the feature?

Daily impressions across those two weeks — straight from the X dashboard.
On two of those days I posted nothing at all and the account still grew. That's what "a loop that runs itself" is supposed to mean.
Discovery isn't a popularity contest
Most tools hand you whatever is trending. A post with 500 replies is worthless to you — yours will never be seen. We rank by the expected value of replying.
Competition, not just reach
Every reply already on a post pushes yours further down. A thread with 2 replies beats one with 200, even if the big one has more likes.
The 90-minute golden window
A 20-minute-old post that's climbing is where a reply converts to profile visits. Freshness decays exponentially, so stale threads drop off on their own.
Likes per minute is the earliest signal a post is taking off. We catch posts on the way up instead of after they've peaked.
Topic fit, judged per post
Keyword search can't tell a SaaS post from a stock post that mentions SaaS. An LLM scores every candidate, and anything off-topic scores zero regardless of how hot it is.
Posting cadence that doesn't look like a bot
Built-in slots default to 4 posts a day, spaced 4–6 hours apart across morning, afternoon, evening, and late night — so your timeline reads like a person, not a scheduler dumping a queue.
This exact cadence runs on my own account — 0 → 100 followers in two weeks. See it live:

What we're building next
The discovery engine already finds what's working. The next step is turning that into your own content — on a cadence that looks human.
Learn the pattern, not the post
When Discovery finds a post that's taking off, AI breaks down why it worked — the hook, the structure, the tension — and turns it into a reusable template you fill with your own story. You get the growth pattern without copying anyone's words.
Spacing that's actually enforced
Pick 3–4 posts a day and the scheduler guarantees at least 4 hours between any two, spread across the hours your audience is actually awake. No more accidental bursts that make a timeline read like a bot.
From draft pile to full queue
Review a batch of drafts, keep the ones you like, and drop the whole set into your calendar in one action — automatically slotted into the next open times that respect your spacing rules.

Frequently Asked Questions
What exactly does Sent2X do?
Sent2X is an AI growth engine for X. It runs the full growth loop for you: AI Discovery finds high-signal threads in your niche every day, the Replies inbox drafts responses to your mentions with AI, AI Planner writes a week of posts in your voice, and live analytics show which posts are actually pulling followers. Scheduling is one piece of the loop, not the whole product.
Why does Sent2X grow accounts faster than a normal scheduler?
Schedulers only handle the posting step. Sent2X handles finding what to reply to, 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.
How does AI Discovery help me find posts to reply to?
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 10 trial uses; Pro and Max are unlimited.
What's in the Replies inbox?
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 quota: 5/day on Free, 150/day on Pro, unlimited on Max.
Can AI agents like Claude Code drive Sent2X?
Yes. Generate an API key in Settings and Claude Code, ChatGPT, or any agent can schedule posts, batch-import content plans, and query your queue from the CLI. Buffer and Typefully have no equivalent.
How much does Sent2X cost?
Free ($0, 10 posts a month, 30 AI replies/month, trial access to the AI engines, manual Remix). Pro ($39/month, 900 posts, 150 AI replies/day, unlimited Discovery and Planner, 3 remix agents). Max ($59/month, 1,500 posts, unlimited AI replies, 10 remix agents). Cancel anytime, no long-term commitment.
