## Caption.IM

Caption.IM is a desktop captioning app built around a simple idea: whatever audio is playing on your machine, you should be able to read it and understand it in your language. It captures system audio directly from your device's output, so it works at the operating-system level with Zoom, Google Meet, Microsoft Teams, Webex, Slack Huddles, Discord and any other app that produces sound. There is no browser extension to install and no per-app configuration.

The app combines two capabilities. First, real-time transcription, which renders speech as on-screen text with high reported accuracy. Second, instant translation into dozens of languages, which makes it useful for international meetings, foreign-language lectures and cross-border calls. Caption.IM states that all audio processing runs locally using optimized AI models, so audio never leaves the device, and it also functions offline.

Beyond live use, Caption.IM works as a voice input method, letting you dictate text into any application through the same engine. Captions can be exported as TXT, SRT or VTT for subtitles, meeting notes or archives, and speaker detection labels who said what. Global hotkeys start and stop captioning instantly.

**Pricing & Plans:** Free tier at EUR 0/month with real-time captions, 3 supported languages and 5 hours per month. Pro at EUR 9.9/month adds 50+ languages, unlimited hours, real-time translation, SRT/VTT export and priority support free trial available. Enterprise is custom-priced with team management, SSO/SAML, custom integrations and an SLA.

- **Real-time captions from any app:** Captures system audio output so captions appear over meetings, calls, videos, podcasts and lectures without per-app setup.
- **Instant translation:** Translate live captions into dozens of languages to follow international meetings and foreign-language content in real time.
- **On-device privacy:** All audio processing runs locally with optimized AI models, so your audio is never uploaded to the cloud.
- **Voice input and dictation:** Use the same engine as a voice input method to dictate text directly into any desktop application.
- **Transcript export and speaker labels:** Save captions as TXT, SRT or VTT and identify different speakers automatically for cleaner records.

**Strengths:** Works at the system level with virtually any desktop app and audio source; Local processing keeps audio private and allows offline use; Combines live captions with 50+ language translation in one tool; Practical export formats (TXT, SRT, VTT) for subtitles and notes

**Limitations:** Free plan caps languages and monthly captioning hours; Desktop-only, so it is not a mobile or browser solution; Live translation and unlimited hours sit behind the paid Pro tier

## SyncWords

SyncWords is language infrastructure for live media. A broadcaster or event producer sends one audio or video feed, and SyncWords returns the same content in the form each audience needs: same-language captions for accessibility, translated subtitles for audiences who read another language, and AI voice dubbing for viewers who would rather listen than read. The company positions itself as a layer that sits alongside the streaming stack you already run, rather than a replacement for it.

The product line maps to how media is actually delivered. SyncWords Live handles broadcast and streaming captioning and can put captions directly into a live stream from the cloud without re-encoding video or installing caption hardware — around half a second to the video and under two seconds to the captions. Events targets meetings and conferences with a branded caption URL and QR code produced in under a minute, so attendees read captions on their own phones while house displays and confidence monitors show the same page. VOD Express automates captions, subtitles and dubbing for recorded files.

Pricing is usage-based. The site lists pay-as-you-go live AI captioning at around $30 per hour, with effective rates dropping as annual committed volume grows — from $27/hour at 60 hours a year down to $9/hour at 9,000 hours. Usage is counted in hours per language and per output, which matters when one programme needs several subtitle tracks. Standard support is included, and Broadcast and Enterprise agreements add uptime SLAs, 24/7 monitoring and a dedicated success manager.

**Pricing & Plans:** Usage-based paid pricing. Live AI captioning is listed at $30 per hour pay-as-you-go; pre-paid annual packages drop the effective rate from $27/hour (60 hours/year) to $9/hour (9,000 hours/year, most popular). Usage is charged per language and per output. Custom quotes available for enterprise volumes; trial sessions available on request.

- **Live captions from the cloud:** Send your existing SRT/MPEG-TS, CMAF or RTMP stream and get captions back in under two seconds without re-encoding video or adding caption hardware.
- **Custom dictionaries and ASR accuracy:** Human-verified accuracy keeps live captions fast and correct, with custom dictionaries for presenter names, players, places and specialist terms.
- **Multi-language subtitles and translation:** Deliver same-language captions, translated subtitles and AI dubbing from one feed, so a single broadcast reaches every market in its own language.
- **Vocalics AI voice dubbing:** Vocalics AI voice dubbing recreates the speaker's tone and pacing in another language, suitable for live news, sports, events and live shopping.
- **Integrations and Live API:** Works with AWS Elemental, Brightcove, Dacast, LinkedIn Live, Vimeo, YouTube, PheedLoop and other platforms, with a Live API for custom pipelines.
- **Events with QR code and embed:** Events users can start a session and get a branded URL and QR code in under a minute, with captions on attendee phones and confidence monitors.

**Strengths:** Delivers captions, translated subtitles and AI dubbing from one pipeline; Can insert live captions without re-encoding video or adding hardware; Transparent published hourly rates that drop with committed volume; Strong integration story across AWS Elemental, Brightcove, Vimeo and YouTube

**Limitations:** Commitment-based annual pricing puts the best rates out of reach for small teams; Custom quotes are required before you know your real cost; Atmospheric preservation in AI dubbing is good but not studio-perfect for every accent; Charges are per language and per output, so multilingual runs add up quickly
