Replying is how accounts grow.Finding the post is what takes the hour.
OpenTweet surfaces recent posts in your niche that are still moving, drafts a reply against the one you pick, and hands it to X’s composer. You press send, because since February 2026 that is the only way a reply can legitimately leave a self-serve account.

Why there is no auto-send
X restricted programmatic replies on self-serve access tiers on February 23, 2026. A reply sent through the API returns a 403 for everyone outside Enterprise. Tools still advertising hands-off replying are either on Enterprise pricing or driving a logged-in browser, and the second one risks the account it is meant to grow. OpenTweet automates everything up to the send and stops there.What you actually do
Four steps, and the first one happens once.
Pick your niches once
Choose up to three. They are the same niches Inspiration uses, so if you have already set them you are done. Without them nothing is searched at all, which is deliberate: a feed with no niche is a feed of noise you pay for.
Open Replies and read the feed
Recent posts in those niches, ranked by whether a reply is worth writing right now. Nothing older than 12 hours, nothing under 5 likes, and the niches interleaved so one cannot take over the top of the list.
Draft against the post you want
Pick an angle and the draft arrives in your tone and length. Edit it. The original post, its author and its traction are all in front of you while you do, which is the context a chat window never has.
Send it from X
The extension drops the text into X’s reply box on the real post. Without the extension it goes to your clipboard and the post opens in a new tab. You read it once more and press reply.
What the feed is doing while you read it
Ranked, not just recent
Every candidate is scored on whether replying is worth it now. Reply value decays in minutes, so a feed sorted by time alone sends you to threads that stopped moving an hour ago.
Reading the feed is free
Only a refresh spends a search. Mounting the page, paging with Load more, or coming back after lunch replay what you were already served, so moving around the app cannot burn your day’s quota.
Your voice, four ways in
Agree and extend, counterpoint, ask a question, share experience. The angle changes what the draft argues, not just how it sounds, which is the difference between a reply and a compliment.
Replied posts stay gone
Anything you have replied to drops out of your feed for 30 days, so you are never accidentally the person who replies twice to the same thread in a week.
Nothing sends itself
No auto-send, no bulk, no scheduled replies. Every reply leaves through X’s composer with a person behind it, which is what keeps this inside the rules rather than one policy sweep from being switched off.
No developer account, no API bill
Replies never touch the X API, so there is nothing to apply for and no per-call charge. Your existing connected account is all it needs.
Against a tool that promises autonomous replies
The difference is one row, and it is the row that decides whether your account survives the quarter.
| "Autonomous" reply bot | OpenTweet Replies | |
|---|---|---|
| Finds posts worth replying to | Yes | Yes, ranked and niche-filtered |
| Writes the reply | Yes | Yes, four angles and six tones |
| Sends without you | Yes | No, by design |
| Uses the X API for replies | Blocked since 2026-02-23 | Never |
| Drives a logged-in browser session | Usually, and that is the risk | No |
| Risk to your account | Suspension for platform manipulation | None beyond a normal reply |
| Needs an X developer account | Yes, Enterprise for replies | No |
Questions
Does OpenTweet post replies for me automatically?
No, and nothing on a self-serve plan can. X restricted programmatic replies on those access tiers on February 23, 2026, so a reply sent through the API returns a 403. OpenTweet automates finding the post and writing the reply. The send goes through X’s own composer, from you.
Then what am I actually paying for?
The two slow parts. Finding a post in your niche that is recent enough and moving enough to be worth replying to, and writing something worth reading against it. Typing was never the bottleneck. Scrolling for twenty minutes looking for a live thread was.
How does the reply get into X if the API is blocked?
Through the browser, like a person. With the OpenTweet extension installed, the draft is inserted straight into X’s reply box on the real post. Without it, the draft is copied and the post opens in a new tab. Either way you review it and press reply yourself.
How does it pick which posts to show me?
It searches up to three of your niches, drops anything older than 12 hours or under 5 likes, scores what is left on whether a reply is worth writing right now, and interleaves the niches so one cannot dominate the top. A reply decays in minutes, so nothing stale is ranked.
Does refreshing the feed cost me anything?
A refresh spends one daily search. Opening the page, paging through with Load more, leaving and coming back spend none, because those replay the set you were already served rather than searching again.
How many searches do I get?
2 a day on the trial, 5 on Pro at $11.99 a month, 20 on Advanced at $29, and 50 on Agency at $49. That budget is shared with Inspiration, because both read the same X search surface.
Can I set the voice, or is it one generic style?
Four angles: agree and extend, counterpoint, ask a question, share experience. Six tones from neutral to witty. Three lengths: one line at 120 characters, short at 180, standard at the full 280. Plus a custom instruction of up to 500 characters when none of those are you.
Will the same post keep coming back after I reply to it?
No. A post you have replied to stops appearing in your feed for 30 days.
Is there a bulk reply button?
No, and there will not be. Firing replies in bulk is the exact behaviour that gets accounts actioned, and the reply that earns you a follower is never one of fifty sent in a minute. One reply at a time is the product, not a limitation of it.
Do I need an X developer account?
No. Your X account is connected to OpenTweet the way it already is for posting, and replies never touch the API at all, so there is no developer application, no key, and no per-call bill for this feature.
