## 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

## Rev

Rev began as a way to turn audio and video into accurate text fast, and it still does that: upload a recording and get a transcript, add captions or subtitles to video, or hand the job to human transcriptionists when accuracy has to be guaranteed. What has changed is where the product now points. Rev has repositioned around an investigative intelligence and legal platform, aimed at prosecutors, defence teams, law enforcement, civil litigators and court-reporting agencies.

The core of that platform is a case workspace. Teams bring body cam footage, jail calls, interrogations, depositions, reports, Word documents, PDFs and photos into one secure place; Rev transcribes every recording, then lets users ask questions across all of that material at once. Every answer cites the file and passage it came from, which matters when a finding has to stand up in court. Image analysis flags inconsistencies across case photos, and the document editor turns a finding into a memo, outline or motion that exports to Word or PDF.

Alongside the AI platform, Rev retains its long-standing human-verified services — human transcription at 99%+ accuracy, human captions in English and Spanish, legal rough draft and premium transcripts, court reporting and global subtitles in 17 languages — and its rev.ai speech-to-text API for developers. Data handling is a stated priority, with SOC 2 Type II auditing and a commitment that customer data is not used to train third-party large language models.

**Pricing & Plans:** Contact for pricing. Rev offers a free trial with no credit card required, self-service AI transcription and captioning at published per-minute rates, and a public pricing calculator that estimates human and AI transcript, caption and subtitle costs. Legal and investigative platform plans are enterprise-oriented and quoted per organisation, while human transcription is priced by turnaround speed and audio length.

- **Multi-file evidence analysis:** Upload recordings, reports, PDFs and photos into a single case, ask questions across every file and get answers cited back to the source.
- **Document editor and drafting:** Turn findings into memos, outlines or motions inside Rev, edit inline and export straight to Word or PDF.
- **Image analysis:** Flag inconsistencies across case photos automatically, with every finding linked to the exact image it came from.
- **AI and human transcription:** Clean, searchable transcripts for body cam, calls and interviews, generated by AI in minutes or by humans at 99%+ accuracy, with inline editing and clipping.
- **Captions, subtitles and developer API:** Captions and subtitles for video distribution and accessibility, plus a speech-to-text API for developers who want to build Rev's engine into their own products.

**Strengths:** Rare combination of AI speed and human-verified accuracy at 99%+ in one platform; Purpose-built legal and investigative workflow that cites every answer back to the source file; Broad format support: audio, video, Word, PDF and images handled in the same case workspace; Established trust with 2,000+ law firms and agencies, with SOC 2 Type II auditing

**Limitations:** Human transcription and captions cost considerably more than pure DIY AI tools; The product has shifted heavily toward legal and investigative teams, so general creators may find the current framing intimidating; Very long files and specialised legal formats can still need manual review; Enterprise legal features and human services are quote-based, so pricing requires contacting sales
