On X
FounderReply drafts X posts and replies and holds them for approval before anything sends from your connected account. X is Pro-only and bring-your-own-credentials: you register your own X developer app, so the API tier, the rate limits and the spend stay yours rather than being pooled across customers.
On X
X work is a habit, not a campaign. You read the timeline, you find the two posts worth a real answer, you write something specific under them, and you come back and do it again tomorrow.
Scrolling for the threads where your experience is the answer: the launch post, the “what are you using for this?” question, the founder describing the problem you solved last year. A handful of them are worth your time.
A reply that earns a click has a number, a decision or a scar in it. That takes a few minutes of thinking per post, and the good version reads like you typed it between two meetings.
X pays attention to accounts that keep turning up. Five replies a day for a month builds a name in your niche; five replies in one afternoon and then silence builds nothing. The work is the frequency.
X, as it looks
The thread, the reply and the message — drawn as X draws them, with the agent's draft arriving in each one. What you see here is what lands in your approval queue.
In the thread
A thread is a room that is already full. Your reply joins it in sequence, under the post and the replies it answers, so it reads as part of the conversation rather than an interruption.
Under someone else’s post
The post being answered stays on screen while the draft is written into the composer. You read both together, press Post, and the reply count moves.
In the DMs
When a conversation moves to DMs, the reply is drafted there too, in the same thread and the same voice, and goes out once you say so.
The case
X is the open room where operators, investors and press read in public. A founder who posts there is findable by people who reach you through a thread instead of an inbox, and the conversation about your category is running there today.
Where your buyers read
Operators, investors and journalists keep X open during the working day. A post that lands in the right replies gets read by the person who signs the contract and by the person who writes about you, in the same hour.
Replies out-reach posts
Your own post reaches the people who follow you. A reply under a post with traction reaches everyone reading that post, which on X is the fastest route from zero followers to a room full of your exact buyers.
Earned, not bought
X distribution is compounding attention: the same handle showing up under the same kind of thread, week after week, until people recognise the name. That is a schedule problem rather than a budget problem, which is why a small company can win it.
Your category is there
Open the search for your category and you will find the competitors, the build-in-public threads and the buying questions, all timestamped this week. Being in those conversations is table stakes for a founder-led company, and the seat is free.
Getting connected
Four steps, and the second one is the only place you do anything. The credential below is the literal artefact the connect flow uses — not a marketing paraphrase of it.
FounderReply acts on the account you sign in with, under a connection you authorise yourself and can withdraw again from X whenever you like. It never makes an account of its own.
Authorisation happens against your own X app with PKCE, and the offline.access scope is what supplies a refresh token so the connection survives without you re-authorising.
tweet.read tweet.write users.read dm.read dm.write like.write offline.accessDiscovery runs on that connection: it finds the X threads where you are a genuine answer and pulls the parent in with the draft, so you are approving a reply in context rather than a sentence with no thread attached. Reading is never gated.
Each action on X has its own level, and you can move any of them — including past where X’s own rules sit, once FounderReply has named the rule you are crossing and the account risk. Your setting is the one that applies, and every change is logged as yours.
Out of the box
One setting decides whether an action happens by itself: your own level for it, per network. Every action ships at what X's own rules allow, and you can move any of it — including past that line, once you have been told which rule it crosses. Read from the connector's capability flags and lib/autonomy.ts at render time.

X’s Automation Rules permit automated posting of your own content but prohibit bulk automated replies and unsolicited automated DMs. Own-content posting and replies on your own posts therefore start unattended; DMs and comments on other people’s posts start held for a human.
The room
X is where product launches, build-in-public threads and "what are you using for X?" questions happen in the open, and where a good reply is more visible than a post. The people you want are already in someone else’s replies. That makes X the platform where drafting speed matters most and where a badly judged automated reply is punished fastest.
X’s spam policy is written around patterns rather than intent: identical replies at volume, unsolicited DMs, and reply-guy behaviour on accounts you have no relationship with. Everything that keeps you inside the rules also happens to be what makes a reply land.
The gate
X is reached with OAuth 2.0 + PKCE, on the account you connected. The agent reads freely, drafts in your voice, and stops at your queue — and whether a given action keeps stopping is a dial you own, per action.

Ready when you are
The free plan connects one account, and nothing is published to X until you release it.
