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 When2Meet 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.

  • How to Have a Successful College Experience (tailored to freshmen but all are welcome to read!)
    · Know how to handle group projects. Whenever you can, work with 1-2 people you trust, as coordinating meetings with fewer people is easier and it's less likely you'll have to deal with a terrible group member. Make a group chat with all members soon after the project is assigned to plan responsibilities and a list of deadlines. Even if you don't get to work yet, having these expectations upfront will help later... Source: about 4 years ago

    This is a unique situation, this group will be perfect for you if your schedule changes weekly due to work. Every Saturday I will put up a calendar from when2meet.com (here's an example of what one would look like: https://www.when2meet.com/?13707207-P379a). Source: almost 5 years ago
  • If any of you schedule games like this, you are the sole reason I want to rip my hair out every time I prep for sessions. I'm red (DM) player is black. You have no idea how bad these guys are at keeping a schedule straight.
    If you want to try to set it up online, I highly recommend when2meet.com, can set up good times by date or day and get real specific. Source: about 5 years ago
  • Project Question
    I'm looking to create a clone of the website when2meet.com for a project. Can anyone help me with where to start and how I should go about doing this? Thank you in advance. Source: over 5 years ago
  • Is it wrong of me to expect communication from my players?
    Personally I have not used meetme.com before, but I do use when2meet.com quite often. It lets you select the days you want to look at (maybe giving them a 2 week range) and you each fill out what times on those days you are available. Then give them a deadline to have their info input, maybe 3 days as it shouldn't take more than 5 minutes. Source: over 5 years ago
