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.

Questions & Answers

As answered by people managing Castmint and ClientSync.

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.

ClientSync's answer:

  • Zero-Friction Client Onboarding: Built as a native Telegram Mini App, clients can view schedules, services, and book appointments instantly without downloading separate apps or creating accounts.

  • Smart Waitlist Engine: An automated background scanner instantly invites waitlisted clients to grab newly opened time slots whenever a cancellation occurs.

  • Dynamic Multi-Service Cart: Calculates total duration and pricing for complex bookings (e.g., Removal + Manicure + Gel Coating) while dynamically finding continuous open slots.

  • Phone-Level Gatekeeper: Protects masters from chronic no-shows through normalized phone-level blacklisting that prevents ban evasion.

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.

ClientSync's answer:

  • Higher Conversion Rates: Eliminates the "app download barrier" that causes high drop-off rates on platforms like Altegio or Dikidi.
  • Zero Financial Risk: Offers a full 30-day Pro trial with complete access to premium features, requiring no credit card or automatic recurring billing.
  • Seamless Telegram Integration: Both clients and masters manage everything inside the messenger they already use daily.

  • Privacy-First Calendar Sync: Two-way iCal synchronization with Google and Apple Calendars keeps client phone numbers hidden by default.

  • Rapid 2-Minute Setup: Masters can construct their online showcase, configure services, and launch bookings in under two minutes.

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.

ClientSync's answer:

  • Beauty & Wellness Specialists: Nail technicians, lash artists, brow experts, estheticians, masseuses, and barbers.
  • Private Practitioners & Educators: Tutors, language teachers, psychologists, and personal fitness trainers.
  • Creative Freelancers: Photographers, videographers, and studio managers.
  • Solo Entrepreneurs: Independent service providers who want to automate DM inquiries and focus on their primary trade.

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.

ClientSync's answer:

  • ClientSync was born out of a real frustration shared by independent service masters in Ukraine: spending hours replying to repetitive DM messages like "What time are you free?" while losing prospective clients who couldn't wait for a reply. Existing CRM solutions were overly complex, expensive, and forced clients to install heavy standalone mobile apps. We envisioned a lightweight, friction-free alternative that lives entirely inside Telegram, giving solo entrepreneurs a powerful digital administrator that works 24/7.

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.

ClientSync's answer:

  • Backend Framework: Python (FastAPI)

  • Database & Storage: PostgreSQL with JSONB schema for historical booking snapshots

  • Task Queue & Caching: Redis with ARQ worker architecture for idempotent PUSH notifications

  • Frontend & Web App Interface: Modern JavaScript, HTML5, and CSS3 running natively inside Telegram WebApp API

  • Integrations: Telegram Bot API and iCal protocol for two-way calendar sync

Who are some of the biggest customers of your product?

ClientSync's answer:

  • Independent Beauty Salons & Solo Nail Studios
  • Private Barbering & Hair Styling Practices
  • Personal Fitness & Crossfit Trainers
  • Private Psychological & Psychotherapy Consultations
  • Independent Language Tutors & Educational Mentors
  • Commercial Photography & Creative Production Studios
