We shipped the first two LeanVox free tools for creators and builders: one for choosing a voice before you commit, and one for turning audio or WebM recordings into usable captions.
Both tools are intentionally small and honest. They are capped, free to try, and scoped to what is deployed today.
#1. Voice A/B Tester
Voice A/B Tester helps you compare two AI voices on your own short script.
Paste text, generate two anonymous Standard voice samples, listen side by side, vote, then reveal which voice you preferred.
Current free limits
- 300 characters per comparison
- 3 anonymous comparisons per IP per day
- Curated Standard voices
- Blind reveal after vote
This is useful when a generic demo line is not enough. Try a podcast intro, video narration line, audiobook sample, app onboarding sentence, or product voiceover before you generate more audio.
#2. Subtitle/Caption Generator
Subtitle/Caption Generator turns uploaded audio files and WebM recordings into timestamped captions.
Upload a supported file, preview readable subtitle cues, then download SRT or VTT.
Current free limits
- Upload-only audio and WebM MVP
- 2 files per IP per day for anonymous use
- 100 MB max upload
- Sync-safe short files for anonymous users
- SRT and VTT output only
- No URL import or broad MP4/MOV support in this MVP
Create a free account when you need longer files, background processing, dashboard history, or API use.

#Why these tools are capped
The goal is not to hide limits. The goal is to make the workflow easy to test without overpromising what the MVP supports.
Voice A/B Tester is built for quick voice-fit decisions. Subtitle/Caption Generator is built for short upload-to-caption runs. If either workflow fits your project, LeanVox gives you a path into the dashboard, API, and larger authenticated jobs.
