Captions AI built a strong product around one big idea: clone yourself into an AI Twin and ship UGC-style videos without filming. If that's your exact workflow it's hard to beat. But for creators who want a broader engine — text-to-video, MP3-to-video, clipping, AI video models — Captions AI starts to feel narrow. Vexub is a six-mode video engine priced at €1 per finished video.
This comparison is for creators choosing between an avatar-first UGC tool (Captions AI) and a general-purpose video engine (Vexub).

Where Captions AI falls short in 2026
Captions AI is excellent for one job: creating UGC-style talking-head shorts with a cloned avatar. Where it loses ground is everywhere else.
Narrow scope. No YouTube clipping, no MP3 or MP4 to vertical workflow, no integration of frontier AI video models (VEO 3, Kling, Grok). The product is built around the avatar.
Tier gating. Dynamic captions with advanced animation are Pro and Business only. Full AI Twin customization is Business only. The Starter plan can feel underpowered.
Credit math. Plans are priced in credits — Pro $9.99 for 200 credits, Max $24.99 for 500. Each AI action burns credits at different rates, and overages run at $0.25-$0.35 per minute.
Uncanny valley risk. AI Twin clones are improving fast but a small percentage of viewers still spot the artifice. For some channels this hurts trust and retention.
What Vexub does differently
Vexub does not chase the avatar play. Instead it gives you a video engine that handles six different input modes, so you can pick the format that fits each video instead of forcing everything through a talking head.
Six creation modes in one tool
Text-to-Video. Prompt to vertical video with AI voice and animated subtitles.
MP3-to-Video. Upload a voiceover or podcast, get a vertical short.
MP4-to-Video. Re-edit horizontal footage into vertical with B-roll.
SMS Video. Recreate viral SMS conversation videos.
AI Video (VEO 3, Kling, Grok). Cinematic AI shots from a prompt.
YouTube Clipping. Vertical clips from any YouTube URL with active speaker detection.
13 subtitle presets, ElevenLabs v3 voices
Vexub ships 13 animated subtitle presets (word-by-word karaoke, dynamic emojis, bold typography) included on every paid plan. Voices come from ElevenLabs v3 in 80+ languages — no separate add-on, no credit ladder per voice clone.
Predictable price per finished video
Vexub plans are priced in finished videos. €30 entry plan = 30 finished videos = €1 per video, regardless of which mode you used. Yearly billing applies a 60% discount.

When to pick Captions AI
Captions AI is the better choice if your entire content strategy is talking-head UGC.
You want to clone yourself into an AI Twin and ship UGC ads at volume.
Your channel format is consistently a single avatar talking to camera.
You don't need clipping, AI video models or text-to-video from prompt.
When to pick Vexub
Vexub fits better when you want a video engine that adapts to any format.
You produce a mix of faceless shorts, repurposed clips and AI video shots.
You clip YouTube videos AND generate new ones from prompts.
You want predictable pricing (€1 per finished video) instead of credit math.
You want VEO 3, Kling or Grok video integrated into the same dashboard.
Bottom line
Captions AI is the avatar-first UGC tool. Vexub is the video engine that fits every other format. If you are stacking Captions AI ($9.99) with a clipper ($15) and a text-to-video tool ($25), you are paying around $50 a month for partial coverage. Vexub gives you all of it for €30.
