Motionly vs Synthesia
Synthesia and Motionly solve different problems. Here is what each actually delivers, what it costs, and who should pick which — no marketing fog.

Pick Motionly if
…you need a product ad that shows your actual app with motion, voiceover and music, ready to post.

- Strong for training, onboarding and internal comms

Where a SaaS founder making a product ad hits friction
- The video is a person talking, not your product moving — a SaaS ad needs the UI on screen.
- You write the script, pick scenes and lay out slides yourself.
- Avatar-led ads read as corporate on social feeds where founders advertise.
What Motionly is
Motionly is an AI ad service for SaaS and app founders: paste your product URL and it delivers a finished, brand-accurate motion video ad — real UI, voiceover, music — in about two minutes, from $20/month.
- Input is a product URL or a short brief — no footage, no script, no designer needed.
- Output is a real motion ad built from your actual product UI (not stock clips, not an avatar reading a script).
- Brand DNA is read from your site: logo, colors, fonts and tone stay consistent across every ad.
- Every ad ships with voiceover and music; text on screen is synced to the spoken words.
- Edits are made in plain-English chat inside the Studio; you keep full control.
- Delivered as 1080p MP4 in landscape, square and vertical for LinkedIn, X, YouTube, Instagram, TikTok and paid social.
- Built for people who launched an app with Lovable, Base44, Replit, Bolt, v0, Bubble or by hand and have zero marketing assets.
- First ad on the free plan, no credit card. Paid plans start at $20/month.
Pricing
Motionly: Free plan with 50 credits (about 3 videos). Paid plans from $20/month for about 10 videos; a founding offer of 50% off for life is running while seats last.
Synthesia: see their pricing page — plans and limits change often, so we don't quote numbers we can't keep current.
