Mac app for X · Apple Silicon

Miso runs your X engagement in the hours you choose.

TweetAgent finds tweets worth answering, likes them and writes replies that add one specific thing. It also posts, takes and follows. It runs on a schedule inside your hours, or when you press Run.

Version 3.0.17 · signed and notarized · updates itself · uses your own AI key

What Miso does

Six jobs, one cat.

  • Replies that add one thing

    Finds tweets, likes them and replies with one specific point. No "great point" replies.

  • Posts and takes

    Writes and posts a new tweet, or a short opinion on your topic.

  • Its own browser

    X runs in a separate protected browser that stays signed in, so X does not keep asking you to log in.

  • Your AI key

    OpenAI, Anthropic or OpenRouter, billed to your own account. Your app AI key is encrypted by the macOS keychain.

  • Your hours

    Runs on a schedule inside your hours, or on demand with Run now.

  • Stops when unsure

    If it cannot tell whether something posted, it pauses that account for your check.

OptionalLearn from my recent posts. Miso reads your recent posts and drafts a persona (topics, voice, examples). You review it before it is saved.
Safety

When Miso is not sure, Miso stops.

  • Never re-sendsA post that matches one this account already published is skipped.
  • Unsure means pausedAn uncertain outcome pauses the account until you check it.
  • Daily AI spending limitYou set the limit. AI work stops when the estimate reaches it.
  • One browser per accountOne account's browser never acts as another account.
  • Your internet, or a fixed proxyEach account can use one fixed proxy. If not, it uses your home internet.
  • Keys in the keychainYour app AI key is encrypted by the macOS keychain.
