## Rev

Rev is a speech-to-text and investigative intelligence platform that combines fast AI transcription, captions and subtitles with human-verified services and legal-grade tooling. Legal, law-enforcement and media teams upload recordings, documents and photos into a secure case workspace where Rev transcribes everything, answers questions across all files with citations, drafts documents and exports polished transcripts for court or publication.

**Preços e planos:** 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.

**Pontos fortes:** 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

**Limitações:** 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

## Whisper (OpenAI)

Whisper is OpenAI's open-source, general-purpose automatic speech recognition (ASR) model. Released as a Transformer sequence-to-sequence system trained on large-scale weakly supervised audio, it handles multilingual transcription, speech translation into English, and spoken language identification from a single set of weights. The code, model weights and command-line tools are published on GitHub under the MIT license, so anyone can run local transcription without paying per minute.

**Preços e planos:** Free and open source. The code and weights are published on GitHub under the MIT license with no usage fees or per-minute charges, though you pay for whatever compute you run it on and any OpenAI API usage if you pair it with their hosted services.

- **Multitask single model:** One Transformer handles transcription, speech translation into English, language identification and voice activity detection, selected through special task tokens.
- **Multiple model sizes:** Choose from tiny, base, small, medium, large and turbo checkpoints, with English-only .en variants, to balance accuracy against VRAM and speed.
- **Broad language coverage:** Multilingual checkpoints transcribe and translate dozens of languages, with automatic language detection on mixed-language audio.
- **Command-line and Python API:** Install via pip with openai-whisper and transcribe files from the terminal or from your own Python code, with ffmpeg handling audio decoding.
- **Permissive MIT license:** Freely embed, modify and redistribute the code and weights in commercial and personal projects without licensing fees.

**Pontos fortes:** Completely free and open source under a permissive MIT license; Strong multilingual accuracy across many languages with automatic detection; Runs locally, so audio never has to leave your hardware; Several model sizes let you match accuracy to available compute

**Limitações:** No hosted UI, account or support — you must install and operate it yourself; Large models need substantial VRAM and a GPU for reasonable speed; Accuracy drops noticeably on low-resource languages and noisy audio; Setup requires Python, PyTorch and ffmpeg, which can be fiddly for non-developers
