FreeTTS.ai vs Live Captions by Subanana

FreeTTS.ai and Live Captions by Subanana are both audio & voice tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

FreeTTS.ai

FreeTTS.ai converts text to speech in the browser with no account required, drawing from 322 voices across 75 languages and eight style presets ranging from 'Newsreader' to 'Scary.' The anonymous free tier caps you at five generations per session — hit that ceiling and the page itself points you toward ElevenLabs. Sign up and the daily allowance rises to 50. An API is available for developers who want to pipe the service into their own tooling, though the vendor page offers little detail on rate limits or SLA. For one-shot narration needs, this clears the bar. For anything recurring, the ceiling arrives fast.

Live Captions by Subanana

The tool covers four distinct workflows under one interface: video subtitling with glossary enforcement, verbatim transcription with word-level speaker separation, meeting capture without requiring a bot to join the call, and live captioning for in-room or public-display audiences across 95+ languages. Dual ASR engines run per language pair with millisecond timecodes, and custom glossaries correct terminology before translation — each substitution logged. Export options include SRT, VTT, FCPXML, XLSX, Markdown, and burned-in video up to 4K. The free tier caps projects at 15 minutes, which surfaces the wall fast for anyone processing long-form content. No API is available, so teams that need to wire this into an existing pipeline hit a dead end and look elsewhere.

Platforms	Web browser	Web, Chrome extension
Pros	No account required to generate audio, so you can test voice quality and style fit before committing any credentials or payment information. Eight voice style presets (including Newsreader, Storyteller, and Energetic) built on top of the voice selector, which means you get distinct delivery tones without post-processing or prompt engineering. 322 voices across 75 languages, so a multilingual content team can cover narration in a non-English language without sourcing a separate tool. API access is available, so developers can wire the service into their own pipelines rather than relying entirely on the browser interface. Speed control is exposed directly in the interface, so you can produce a slower, measured narration for educational content or a faster cut for social clips without editing the audio file afterward.	Dual ASR engines run per language pair with millisecond timecodes and silence recovery, so the exported file stays frame-accurate even when audio quality dips between speakers. Glossary enforcement corrects domain-specific terms before translation and logs every substitution, which means brand names, product terms, and specialized vocabulary survive the language switch without a manual review pass. Word-level speaker diarization splits overlapping voices at word boundaries and carries named roster labels through every export format, so a two-hour interview with four speakers arrives as a quotable, attributed transcript rather than an undifferentiated wall of text. Export covers SRT, VTT, FCPXML, XLSX, Markdown, and burned-in video up to 4K, which means the same processed file hands off to a video editor, a data analyst, and a publishing workflow without conversion steps. A no-bot browser extension captures meetings without joining as a participant, so teams whose platforms block third-party bots can still get a transcript without requesting IT exceptions.
Cons	The anonymous session cap is five generations — a single round of iteration on one script exhausts it. Signed-in free accounts get 50 per day, but a team producing daily video narration burns through that before noon, at which point they are either paying for credits or switching tools. The 2,000-character input limit means a five-minute script requires manual chunking and multiple generation passes, then manual stitching of the audio segments. There is no built-in project or chapter management to handle this. No voice cloning or custom voice upload is offered. Teams building a branded audio product — a podcast with a consistent host voice, or a support bot that should sound like a specific person — find this ceiling immediately and move to ElevenLabs or a comparable service that supports cloning. No self-hosted or local option exists. All generation happens on FreeTTS.ai servers, so teams with data-handling obligations around voice input or script content have no path to keeping that data off a third-party service.	The free tier caps each project at 15 minutes, so a 90-minute interview or a two-hour event recording hits the wall on the first upload — teams processing long-form content regularly are immediately into paid territory and need to budget accordingly before starting. No API is available, which means every file requires a manual upload through the web interface. Teams that generate transcription jobs programmatically — automated ingest pipelines, post-production workflows triggered by a CI step — cannot integrate this tool and move to a competitor that exposes an endpoint. Live captioning and meeting transcription depend on a stable connection to the Subanana service with no self-hosted option, so organizations under strict data-residency requirements or operating in environments where outbound connections to third-party SaaS are restricted cannot deploy this tool.

Bottom line

Only FreeTTS.ai exposes a public API. Choose based on which difference matters most for your workflow.
