Key takeaways
OpenTweet (opentweet.io) is a cheap scheduler and posting layer built for AI agents, from $11.99 a month ($9.99 billed yearly). Its MCP server and API let an agent post without its own developer account.
It is no longer Twitter-only. One draft now cross-posts to Twitter, Bluesky and LinkedIn as native posts, with Threads listed as coming soon. Accounts per plan are still counted as Twitter accounts.
Three plans, with real limits: Pro (20 posts and 10 AI generations a day, one Twitter account, no link posts), Advanced at $29 (100 posts, 10 with links, three accounts, analytics), Agency at $49 (300 posts, ten accounts).
It now sends DM campaigns on paid plans, and scheduled posts publish on autopilot. That is convenient, and it sits closer to what Twitter restricts than an approve-each-post workflow.
It learns a style profile from your posts but shows no per-draft check of how closely a draft matches you.
If you want a full workspace for Twitter and LinkedIn with a check on every draft, compare it with VoiceMoat, the Personal Brand OS for LinkedIn and Twitter: $1 for 3 days, plans from $35 a month. Disclosure: VoiceMoat is our product.

What is OpenTweet?
OpenTweet is a scheduler and AI writer at opentweet.io, priced from $11.99 a month. It drafts posts and threads, schedules and publishes them, learns a style profile from your posts, and, most distinctively, gives AI agents an MCP server and API so they can post through it without their own developer account. Its page title sums up the pitch: “Post to X from AI Agents”.
That gives it a split personality. On one side it is an inexpensive scheduler with AI writing, an evergreen queue and analytics. On the other it is a developer tool that lets automations and agents post without wrestling with each network’s own API.
What changed in 2026
Cross-posting. One draft now goes out as a native post on Twitter, Bluesky and LinkedIn, with threads kept as threads where the network has them. Threads (the app) is listed as coming soon. LinkedIn posts go to your personal profile through OpenTweet’s own LinkedIn app, and the sign-in lasts 60 days before you reconnect.
Clearer limits per plan: posts a day, posts with links, AI generations, API keys and API rate limits are all spelled out.
DM campaigns. Paid plans can send DM campaigns; the trial only finds and qualifies prospects.
Annual billing: two months free, which takes Pro to $9.99 a month.
Who OpenTweet is for
There are two audiences. The first is budget-minded creators and founders who want a cheap scheduler with AI drafting and an evergreen queue, mainly for Twitter. The second, and the more distinctive fit, is developers, indie hackers and anyone running AI agents who wants those agents to post programmatically. If you are in the second group, OpenTweet’s agent layer is a genuinely useful shortcut. It is a weaker fit if you want company pages on LinkedIn, replies and engagement in the same place, or a visible read of how closely each draft matches your voice.
The distinctive angle: posting from AI agents
OpenTweet ships an MCP server, a REST API, a CLI and a desktop assistant extension, so you can connect an AI agent or an automation and have it post, publish threads, batch-schedule and fetch analytics, without the agent holding its own developer credentials. OpenTweet holds the connection; the agent calls OpenTweet’s tools. It also offers connectors that post automatically from sources like RSS feeds, code repositories, payment events and webhooks. For anyone building AI-driven content workflows, that removes real friction. The posts still go out through Twitter’s metered API, and our breakdown of X API pricing shows what each one costs.

Post on LinkedIn and Twitter in a way that reads like you
VoiceMoat is the Personal Brand OS for LinkedIn and Twitter. audenAI, the brain inside it, learns from your own posts, then helps you create, schedule and grow.
Creator plan $35 a month after the trial. Cancel anytime.
OpenTweet’s features
AI Studio: a chat interface with a choice of AI models that drafts posts and threads you save as drafts.
Voice learning: a style profile built from your posts and applied when it writes. No per-draft check.
Scheduling: a visual calendar, a best-time view on paid plans, and batch scheduling.
Evergreen queue: recycles your best posts automatically.
Long-form: threads and Twitter Articles.
Connectors: post automatically from RSS, code repositories, payment events and webhooks.
Agent layer: MCP server, REST API, CLI, plus a Chrome extension.
Posting posture. Scheduled posts publish on autopilot, connectors post from your sources, and paid plans can send DM campaigns. That is convenient, but it is a different model from a tool that asks you to approve each post, and DM campaigns sit close to what Twitter restricts as automation. If you prefer to approve everything before it ships, factor that in. Xpert takes the opposite approach on Twitter, holding every reply and DM in an approval inbox; see our Xpert review.
OpenTweet pricing (2026)
OpenTweet is cheap, which is much of its pitch. Every plan starts with a 7-day free trial; a card is required and nothing is charged until day 7. Annual billing gives two months free.
Plan | Monthly | Billed yearly | Main limits |
|---|---|---|---|
Pro | $11.99 | $9.99 a month ($119.90 a year) | 20 posts and 10 AI generations a day, 1 Twitter account, 5 connectors, no link posts listed |
Advanced | $29 | $24.17 a month ($290 a year) | 100 posts a day (10 with links), up to 3 Twitter accounts, 50 AI generations a day, analytics dashboard |
Agency | $49 | $40.83 a month ($490 a year) | 300 posts a day (20 with links), up to 10 Twitter accounts, 150 AI generations a day |
OpenTweet’s plans, checked on opentweet.io/pricing on 12 October 2026. The page shows the monthly prices next to higher crossed-out prices ($15.99, $39.99 and $79.99). The trial leaves out the evergreen queue, Twitter Articles and some analysis tools, and caps link posts.
A note on OpenTweet’s reviews
OpenTweet launched in late 2025 and is still a small, independent product. The testimonials on its pricing page are customer quotes it chose, and we found little independent review coverage. None of that makes it a bad tool for the money, but you are backing a young product, so use the trial and judge it yourself, especially before you route an automation through it.
Strengths and limitations
Where OpenTweet is strong
Price: one of the cheapest full-featured schedulers, from $11.99 a month.
The agent layer: MCP and API posting for AI agents is a genuinely distinctive wedge.
Cross-posting to Twitter, Bluesky and LinkedIn from one draft.
Evergreen queue, threads, Twitter Articles and connectors.
Where OpenTweet is thin
Pro lists no link posts and no analytics dashboard; both start on Advanced.
No per-draft voice check, so you cannot see how closely a draft matches you.
Autopilot publishing and DM campaigns, which not everyone wants on their account.
Young product with little independent validation.
OpenTweet vs VoiceMoat, and alternatives
VoiceMoat is the Personal Brand OS for LinkedIn and Twitter. audenAI, the AI inside it, learns how you write from your own posts, then helps you write, schedule, engage, analyse and grow, with Style and Stance checks on your drafts so posts read like you. Try it for $1 for 3 days. Plans from $35 a month. Disclosure: VoiceMoat is our product, so treat this section as biased but honest.
The two aim at different jobs. OpenTweet’s wedge is cheap scheduling plus letting AI agents post for you, with voice as a supporting feature. VoiceMoat is a full workspace for Twitter and LinkedIn: Studio for writing, with Style updating live on every draft and a Stance check of what a draft says; Grow, which plans toward a goal and writes posts for you to review; a calendar; Replies; Analytics; and Media Studio. Nothing posts without your hand on it. If you want the cheapest scheduler or programmatic agent posting, OpenTweet is a strong, inexpensive pick. If you want to read like yourself and check it on every draft, VoiceMoat fits better.
VoiceMoat pricing, October 2026. Annual billing gives two months free. The trial costs $1 for 3 days (Creator) or $5 (Pro and Enterprise), with a card on file, and continues on the plan unless you cancel.
Plan | Price a month | Who it is for |
|---|---|---|
Free | $0 | Looking around; voice training is on paid plans |
Creator | $35 | One to three profiles posting every day |
Pro | $69 | Threads, posting media, Write like a creator, connecting an AI assistant |
Enterprise | $150 | The Deep writing model, team seats and the most profiles |
How it posts: on Twitter, VoiceMoat posts and replies directly. On LinkedIn, posting and scheduling are native, the Chrome extension writes comments straight into LinkedIn’s comment box for you to post yourself, and analytics come through the extension too, because LinkedIn’s API rules are stricter. VoiceMoat can also connect to an AI assistant on Pro and Enterprise. For the wider field, see the best Twitter tools in 2026 and the best LinkedIn tools in 2026, or read what VoiceMoat is.
Is OpenTweet worth it?
At $11.99 a month, OpenTweet is worth trying if you want a cheap scheduler or you specifically want AI agents to post through a simple layer, and the 7-day trial is the way to test it. Weigh the caveats: Pro has no link posts and no analytics dashboard, publishing runs on autopilot, DM campaigns need care, and there is no visible read of how a draft matches your voice. If you want a full Twitter and LinkedIn workspace with a check on every draft, compare it with VoiceMoat first, and judge both on your own writing.
Frequently asked questions
What is OpenTweet (opentweet.io)?
OpenTweet is a scheduler and AI writer, from $11.99 a month, built around a posting layer for AI agents: an MCP server and API that let agents post without their own developer account. It drafts posts and threads, learns a style profile from your posts, publishes on a schedule, recycles evergreen posts, and cross-posts to Twitter, Bluesky and LinkedIn.
How much does OpenTweet cost?
Pro is $11.99 a month ($9.99 billed yearly), Advanced is $29 ($24.17 yearly) and Agency is $49 ($40.83 yearly), checked on 12 October 2026. Every plan starts with a 7-day free trial that needs a card. Pro allows 20 posts and 10 AI generations a day on one Twitter account; link posts and the analytics dashboard start on Advanced.
Is OpenTweet only for Twitter?
Not any more. One draft can cross-post to Twitter, Bluesky and LinkedIn (your personal profile), and Threads is listed as coming soon. Plans are still counted in Twitter accounts.
What makes OpenTweet different from other schedulers?
Its agent layer. OpenTweet gives AI agents and automations an MCP server, REST API and CLI to post through, without holding their own developer credentials. The scheduling and AI writing are competitive but not unique.
Does OpenTweet show how closely a draft matches my voice?
No. It builds a style profile from your posts and applies it when writing, but shows no per-draft check. VoiceMoat shows Style live on every draft and a Stance check of what a draft says.
Is OpenTweet legit?
It is a real, working product, launched in late 2025 and still small. Independent review coverage is thin, so judge it on the 7-day trial and your own results.
What is the best OpenTweet alternative?
It depends on the job. For a full Twitter and LinkedIn workspace with a check on every draft, VoiceMoat. For the cleanest writing and scheduling on six networks, Typefully. If you specifically want an AI-agent posting layer, that is OpenTweet's distinctive feature.

Every social MCP connector reaches both platforms. That is not the hard part
We were going to write that connecting one assistant to both Twitter and LinkedIn was rare. It is not. More than twenty connectors do it and several are free, so channel coverage is table stakes and every roundup ranking them by it is measuring the wrong thing. Here is what actually differs between them, and the one thing we read enumerated tool lists for six of them to confirm nobody does at all.

Why your Claude writing skill doesn't sound like you
There are dozens of free Claude skills for writing, and almost all of them do the same thing: strip out phrases that read as machine-written. That is subtraction, and it leaves you sounding like nobody in particular rather than like yourself. The handful that actually learn a voice from your own writing have a fraction of the users. Here is the difference, why a skill cannot post anything no matter what it says, and where the file actually goes on every surface.
