The Sent2X playbook
How the product fits, how to grow, and what each plan can do
First the growth loop and the operating points, then the quota rulebook and plan capacity. Opening this page spends nothing.
Architecture & growth
Chapter 1
How Sent2X fits together
One loop, not six separate apps. Connect X, keep a voice, find rising posts, reply in that voice, publish on a cadence, and read Home to see what pulled followers.
| # | Piece | What it does |
|---|---|---|
| 1 | X connect + extension | Sign in with X so posting is authorized. The browser extension docks a panel beside x.com and puts a blue pen in every reply box. The panel is an iframe of /embed; full pages like this one open in a new tab so they are not blocked by X's frame rules. |
| 2 | Voice & experiences | We seed a voice profile and an experiences document when you join (on us). Re-learn / Generate is once per local day, also on us. Replies, Remix, and Planner read these so drafts sound like you. Your own edits are kept. |
| 3 | AI Discovery | Topic channels for your niche. A search counts only when new posts are actually fetched into a channel — opening cards already on screen is free. Neighbour prefetch is on us. Each counted search tops a channel toward 15 cards; ranking usually keeps about 20 usable. |
| 4 | AI replies + Remix | Blue-pen on x.com or on a Discover card, custom quick-replies that call the model, extension Translate, Remix drafts, and Planner-plan translation share one pool. Let's connect templates do not count. Type your own angle on a real thread — that is the growth move. |
| 5 | Replies inbox | Mentions land in one place with an AI draft waiting. This is inbound: people already talked to you. Turning those into real replies compounds more than spraying more cold comments. |
| 6 | Planner, queue, agents | Each Planner message you send counts as one, including follow-ups in the same chat. Import lands in the queue. Remix agents (Pro 3 / Max 10) draft overnight in your voice and wait for approval. A post slot is spent only when it actually publishes to X. |
Home (the dashboard, or the panel's Home tab) is the pulse: followers, impressions, engagement, next queue slots. Analytics warm up after X is connected — give it a couple of days.
Chapter 2
How to grow fast on X
Five points, not a 20-item list. They match how Sent2X actually meters and how X ranks early, substantive replies. The billing floor assumes you do this every day.
01
Show up every day
The Usage & billing floor is a daily loop, not a weekend binge. Founder cadence was about four posts a day plus Discovery and replies — including days with no new posts, the account still moved because replies kept running. Skip days and you are below the floor on purpose.
02
Reply early, on threads you would actually join
X pays for early, useful replies on rising posts. Open Discovery daily, prefer posts that are still warming up, hit View (Semi View will open the composer for you). Spend the reply pool on threads in your niche — not on every card the channel can show. 150 replies/day is a ceiling, not a target.
03
Write in your voice, not the template pool
Type a half-formed thought before you hit the blue pen. Connect-post templates are free because they do not call the model — they also do not grow an account. Voice and experiences are on us; keep them current so drafts do not drift into generic AI.
04
Do not burn Discovery on empty refreshes
Opening a channel that already has cards does not count. Warming neighbouring channels is on us. A search is spent when the pool is empty and we actually fetch. Skip or post to free a slot; wait until a channel is below 15 active cards before you force a refill.
05
Close the loop: inbox + a posting cadence
Answer mentions from the Replies inbox — a reply that earns a reply back is worth more than another cold comment. Keep the queue fed with Planner or Remix so Home is not empty. Quotas buy volume of this loop; they do not replace showing up.
Numbers and meters: see Usage & billing. Recorded walkthroughs of each engine: How to Use.
Usage & billing
Chapter 1
How quotas are counted
Each meter has its own window. The table is the product rule — not a guess.
| Quota | What increments it | Window | What does not count |
|---|---|---|---|
| Posts published to X | One slot when a post actually goes out: scheduled fire, Publish now, or post immediately. Remix-agent posts and hand-written posts share this ceiling. A failed publish is refunded. | Free: calendar month in your timezone. Pro / Max: your Stripe billing period (the weekday you subscribed), not the calendar month. No daily post cap. | Drafts. Queued or scheduled posts that have not published yet. Deleting a draft. Opening this page. |
| AI replies + Remix | Each time the model writes or translates: the blue-pen button (when it actually calls the model), a custom quick-reply that calls the model, Translate in the extension, a Remix draft (manual or agent), and translating a Planner post plan. Remix and replies share one pool. | Your timezone, not UTC. Free: 5 per day and 30 per month. Pro: 150 per day. Max: 400 per day. Paid plans have no monthly reply cap. | Let's connect templates (no model call). Blue-pen on a connect post when you have not typed your own angle — that is also the template pool. Type thoughts on a connect post and the model writes it, which does count. |
| AI Discovery searches | Counted only when Sent2X actually fetches new posts from X and new cards are added to a channel. Each counted search tops a channel toward 15 cards on screen; ranking usually keeps about 20 usable posts — you see 15 first, then the rest as you skip or reply. | Free: 30 searches per calendar month in your timezone. Pro: 20 per local day. Max: 30 per local day. | Opening a channel that already has cards. Warming neighbouring channels (we pay). Skipping, viewing, or posting a card. Cards themselves are not a separate meter — the search is. |
| AI Planner messages | Each message you send in Planner counts as one — a new chat's first message and follow-ups in the same chat. Counted when the model actually runs. | Calendar month in your timezone. Free: 30. Pro: 150. Max: 400. | Translating a finished plan — that spends an AI reply, not a Planner turn. A send that fails before a reply starts. |
| Remix agents | How many agents you may keep: Free 0, Pro 3, Max 10. Each generation spends one AI reply + Remix slot; each post that actually publishes spends one post slot. | Agent count is a standing cap, not monthly. Generations use the reply/Remix window above; publishes use the post window. | An idle agent. Creating or editing an agent. Manual Remix still works on Free (it spends the reply + Remix pool, not an agent slot). |
| Voice profile & experiences | We build both once when you join (on us). After that, Re-learn or Generate once per local day — also on us. Each run merges new facts; your own edits are kept. | Manual rebuild: once per local day. Not a paid meter. | Does not spend replies, Discovery, Planner, or posts. |
Limits above match the live product caps. Discovery 20/day ≈ 300 cards on screen / 400 usable if you work through that day; 30/day ≈ 450 / 600. Those are Discovery cards (skip, blue-pen, Remix), not your monthly post allowance (Free 10, Pro 500, Max 750). A blue-pen, translate, or Remix on a card still spends an AI reply.
Chapter 2
What each plan can do in a month — and the floor if you persist
Capacity is the hard ceiling. The return numbers are a floor: the least you should expect if you persist every day, not a maybe-range. They are rounded for clarity, not a guarantee. Niche and account age still matter. Skipping days is what drops you below the floor.
The floor is scaled from the founder account's published two-week run on this tool (0 → 100 followers, 50.8K impressions, 149 replies received) at about four posts a day plus daily Discovery and replies, then stretched to a month of that same daily cadence. Pro already covers that pace with headroom. Max is scaled for extra Discovery/reply volume (~1.5×), not 3× just because the reply cap is higher.
Monthly capacity
| What you can do | Free | Pro · $39/mo | Max · $59/mo |
|---|---|---|---|
| Posts published | 10 / month | 500 / month | 750 / month |
| AI replies + Remix | 5 / day, 30 / month | 150 / day, no monthly cap | 400 / day, no monthly cap |
| Discovery searches | 30 / month | 20 / day | 30 / day |
| Cards if you work through searches | ~450–600 / month | ~300–400 per full day | ~450–600 per full day |
| Planner messages | 30 / month | 150 / month | 400 / month |
| Remix agents | None (manual Remix only) | 3 | 10 |
