One tool instead of five

Stop paying for a stack of tools

Translating, dubbing, subtitling, scheduling and answering comments usually means five logins and five bills. Here it is one workflow and one credit balance.

  • Replaces A translation tool

    The script and the caption are translated for every language you pick.

  • Replaces A voice dubbing tool

    Dubbed in a clone of your own voice, with optional lip sync.

  • Replaces A subtitle editor

    Translated subtitles burned in, in one of six styles.

  • Replaces A scheduling tool

    Nine networks in one calendar, with best-time testing built in.

  • Replaces A comment-reply tool

    A keyword in a comment sends your DM automatically.

Dub

Your voice, in 16 languages

Your voice is cloned from the video itself, so every language sounds like you. No studio session, no stock voice.

  • Dubbed in a clone of your own voice, with your timing and energy.
  • Optional lip sync re-times your mouth to each language. A paid add-on, only when you turn it on.
  • Translated subtitles burned in: Pop, Bold box, Karaoke, Clean, Minimal or Classic.

Publish

Every network. The right account.

Set a language on each account once. The Spanish version goes to your Spanish account, the Japanese one to your Japanese account.

  • Instagram
  • TikTok
  • YouTube
  • LinkedIn
  • X
  • Facebook
  • Threads
  • Pinterest
  • Bluesky
  • Schedule or post now, and see every post in a calendar, a grid or a list.
  • Team workspaces, each with its own accounts, posts and credits.

Best time

Tested on your own account

Not a generic chart of when people scroll. Fifty Eight tries different posting times on your account, measures the results and keeps the times that work.

  • Only the time moves. Never the day, the caption or the video.
  • Between 08:00 and 23:00 in the account’s time zone, at least 2 hours ahead.
  • Mark a post “Keep this exact time” and it stays put.

A comment in. A DM out.

Pick a keyword and write the message. When someone comments the keyword, they get your DM, with a link button, without you opening the app.

  • DMs with a link button on Instagram and Facebook.
  • A public reply under the comment on TikTok, YouTube, LinkedIn and Threads.
  • Each person is answered once per automation. Every plan includes a monthly number of auto-DMs.
