Castmint turns one typed line into a finished vertical short: AI script, voiceover, synced captions and visuals — ready to post on TikTok, YouTube Shorts and Instagram Reels.

The problem: short-form video is the highest-leverage format on the internet, but every single short costs an evening — scripting, recording a voiceover, syncing captions, hunting for visuals, cutting it vertical. That's why most channels go quiet.

What Castmint does: type a topic — "5 underrated productivity apps", "why your houseplants keep dying" — and Castmint assembles the whole thing:

  • Script — an AI-written hook and narration matched to short-form pacing
  • Voiceover — natural AI voices (no camera, no mic, no face needed)
  • Captions — word-timed, styled, burned in
  • Visuals — matched to the script, cut into a vertical 9:16 video
  • Editor — timeline editing of text, captions, images and audio when you want control
  • Publishing — push finished videos to YouTube and TikTok directly from the app

Who it's for: faceless channels, creators who hate editing, and small brands that want to look active on TikTok, Reels and Shorts without a video team.

One input, whole pipeline: most tools automate a single step — voiceover, or captions, or stock clips. Castmint goes from a typed idea to a finished, publishable short in one pass, and still gives you a timeline editor for control.

Your first three videos are free, no card required.

Questions & Answers

As answered by people managing Tuple and Castmint.

What makes your product unique?

Castmint's answer:

Most AI video tools automate a single step — voiceover, or captions, or stock clips — and leave you to stitch the rest together yourself. Castmint goes from one typed line to a finished, publishable vertical short in a single pass: script, AI voiceover, synced captions and visuals, all in one automated flow. You still get a full timeline editor when you want to polish it by hand.

Why should a person choose your product over its competitors?

Castmint's answer:

Castmint removes the assembly work, not just one piece of it. You type an idea and get a complete short ready to post — no separate tools for scripting, voice, captions and editing. Your first three videos are free with no card required, so you can judge the output on your own topic before committing to anything.

How would you describe the primary audience of your product?

Castmint's answer:

Faceless-channel creators, solo YouTubers/TikTokers who'd rather not be on camera, and small brands that want to post consistently on TikTok, Reels and Shorts without hiring a video team or an editor.

What's the story behind your product?

Castmint's answer:

Castmint started because the founder's own channel kept going quiet — not from a lack of ideas, but because every short cost an evening of scripting, recording, captioning and cutting. Castmint automates that whole pipeline, so one typed idea becomes a finished, ready-to-post short in minutes instead of hours.

Which are the primary technologies used for building your product?

Castmint's answer:

Built on Next.js and TypeScript, with AI generation powered by OpenAI, ElevenLabs and fal.ai.

  • JetBrains is shutting down "Code With Me" in all its IDEs
    If anyone out there is looking for an alternative, you should try Tuple: https://tuple.app/ (disclaimer: I work there). When you need to actually get stuff done with other humans, we think Tuple is the best way to do that.

    And this https://tuple.app/ is tuple, previous company gave us subscriptions to use and I was a huge fan of it. - Source: Hacker News / 11 months ago
  • OpenAI Acquires Multi
    It's on the short side, but this isn't a cloud database or whatever. Nobody is using it in production because it doesn't plug into your apps. There are any number of alternatives you can switch to and there's little productivity lost. https://tuple.app/ is the most direct alternative (and excellent) but in the short term there's also VS Code live share, or screen sharing in whatever your main video chat app is. - Source: Hacker News / about 2 years ago
  • Multi – Multiplayer Collaboration for macOS
    This seems similar to Tuple https://tuple.app/. - Source: Hacker News / over 2 years ago
