Castmint turns one typed line into a finished vertical short: AI script, voiceover, synced captions and visuals โ€” 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 โ€” 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 โ€” "5 underrated productivity apps", "why your houseplants keep dying" โ€” and Castmint assembles the whole thing:

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

Bitcut is an AI-powered video editor for iPhone that turns long-form videos into short, scroll-stopping clips ready for YouTube Shorts, Instagram Reels, and TikTok.

How it works

Drop in a long video โ€” a podcast, a lecture, a vlog, a gameplay session โ€” and Bitcut analyzes the content using AI (CLIP + Whisper). It identifies the most engaging moments, crops them to 9:16 vertical format with smart face tracking, and adds animated captions. The result: multiple short clips ready to post, in minutes instead of hours.

Key capabilities

  • Smart Crop 9:16 โ€” automatically reframes horizontal footage to vertical, keeping the speaker or subject centered
  • Beat Sync โ€” aligns cuts to the rhythm of the music using FFT audio analysis, so edits feel natural and energetic
  • Lip-Sync Trim โ€” never cuts a speaker mid-word or mid-sentence
  • Karaoke Subtitles โ€” auto-generated animated captions that highlight words in sync with speech
  • AI Scene Detection โ€” finds the most interesting, shareable moments from long recordings
  • DaVinci Resolve Export โ€” generates OpenTimelineIO XML for professional post-production

Who it's for

Content creators, podcasters, marketers, and social media managers who need to repurpose long videos into short-form content at scale โ€” without spending hours in a timeline editor.

What makes it different

Most AI clipping tools are web-based and require uploading video to a server. Bitcut runs natively on iPhone โ€” processing happens on-device, which means faster results, no upload wait, and full privacy. The beat sync and lip-sync trim features go beyond simple "find highlights" โ€” they produce clips that actually feel edited by a human.

Free to use with basic features. Available on the App Store.

Questions & Answers

As answered by people managing Castmint and Bitcut.

What makes your product unique?

Castmint's answer

Most AI video tools automate a single step โ€” voiceover, or captions, or stock clips โ€” 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.

Bitcut's answer:

Bitcut processes video entirely on-device โ€” no uploading to servers, no waiting, no privacy concerns.

Most AI clipping tools are web-based and require you to upload your footage first. Bitcut runs natively on iPhone and iPad, so a 30-minute video gets analyzed in minutes, not hours.

Key differentiators: - AI Smart Cuts โ€” generates up to 8 Shorts from one video, each with a quality score (hook, completeness, engagement) - Face Tracking โ€” auto-reframes 16:9 to 9:16 by following faces, no manual cropping - Beat sync โ€” cuts aligned to music rhythm automatically - Full timeline editor โ€” completely free, no paywall on core editing tools

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 โ€” 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.

Bitcut's answer:

  • Speed โ€” works offline on your phone, no upload wait, unlike most web-based clipping tools that require cloud processing
  • Privacy โ€” your footage never leaves your device
  • Full editor included โ€” most AI clipping tools only generate clips. Bitcut has a complete multi-track timeline editor for fine-tuning
  • Affordable โ€” $99/year, significantly less than comparable tools on the market
  • AI Subtitles โ€” 7 animation styles with word-level precision, auto-translation to 12 languages

Who are some of the biggest customers of your product?

Bitcut's answer:

  • Independent YouTubers repurposing long videos into Shorts
  • Podcast hosts creating clip highlights for social media
  • Social media managers at small agencies
  • Online course creators extracting key moments from lectures
  • Musicians creating beat-synced promo clips from concerts

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.

Bitcut's answer:

  • Solo YouTubers and podcasters without a dedicated editor
  • Social media managers maintaining posting schedules across platforms
  • Online course creators extracting key moments from lectures
  • Musicians and DJs creating beat-synced promo clips

What's the story behind your product?

Castmint's answer

Castmint started because the founder's own channel kept going quiet โ€” 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.

Bitcut's answer:

Bitcut started as InstaClip โ€” a personal tool built to solve a real problem: turning hour-long podcast recordings into engaging short clips without spending the whole evening in a timeline editor.

The early prototype just found silences and cut around them. Then came AI scene detection, automatic transcription, beat sync, face tracking, and smart reframing.

The name changed to Bitcut โ€” "every bit counts" โ€” reflecting both the digital nature (bits) and the precision of each cut. Built by an indie developer as part of a portfolio of AI-powered media tools.

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.

Bitcut's answer:

  • Swift/SwiftUI โ€” native iOS interface, optimized for iPhone and iPad
  • On-device AI โ€” scene analysis and highlight detection
  • Whisper โ€” speech transcription and subtitle generation
  • FFmpeg โ€” video processing, encoding, format conversion
  • FFT audio analysis โ€” beat detection for music-synced editing
  • Face detection โ€” tracking and auto-reframing to vertical format
