## Immersive Translate

Immersive Translate is an AI translation tool designed around reading and watching, not just pasting text. Its best-known feature is bilingual website translation: it shows the original and the translation side by side in a vertical layout, which makes it easier to compare meaning and learn a language as you read. It runs as a browser extension on Chrome, Edge, Firefox and Safari, and also as mobile apps for iOS and Android.

Beyond web pages, the tool covers documents, video and images. It translates PDF, ePub, HTML, TXT, DOCX, Markdown and subtitle files while preserving the original layout, and can OCR scanned PDFs so they become searchable and translatable. For video, it generates real-time bilingual subtitles on more than 100 platforms, including YouTube, Netflix and Prime Video, and can even translate videos that have no original subtitles. It also handles image and comic translation and adds live translation to online meetings on Zoom, Google Meet and Microsoft Teams.

Under the hood, Immersive Translate integrates more than 20 translation engines, among them ChatGPT (OpenAI), DeepL, DeepSeek and Gemini, and supports over 100 language pairs. Context-aware AI terminology libraries and customizable glossaries help keep names, technical terms and jargon consistent, which matters for academic papers, contracts and technical documentation. According to the project, the extension is used by more than 30 million people.

**Pricing & Plans:** Immersive Translate is freemium: the core bilingual translation features are free, and you can also use your own API keys for third-party engines. A Pro subscription unlocks higher limits and advanced features such as full PDF and ePub translation, with free trials available.

- **Bilingual website translation:** Displays the original text alongside the translation in a side-by-side layout, so you can read in two languages without losing the source.
- **Layout-preserving document translation:** Translates PDF, ePub, DOCX, Markdown and other files while keeping the original formatting, with OCR for scanned documents.
- **Video subtitle translation:** Generates real-time bilingual subtitles on 100+ video platforms and can translate videos that have no original subtitles.
- **Image, comic and meeting translation:** Translates images and comics with OCR and inpainting, and adds live translation to Zoom, Google Meet and Microsoft Teams.
- **20+ engines and 100+ languages:** Choose from engines like ChatGPT, DeepL, DeepSeek and Gemini, covering more than 100 language pairs using AI terminology libraries.

**Strengths:** Side-by-side bilingual display is excellent for reading and language learning; Covers web pages, PDFs, ebooks, videos, images and meetings in one tool; Integrates 20+ engines so you can choose the best one per task; Preserves original document layouts and supports OCR for scanned files

**Limitations:** Best results on some features require a paid Pro plan; Free usage with hosted engines is subject to rate limits; Bringing your own API key means managing separate engine costs

## Whisper (OpenAI)

Whisper was introduced by OpenAI as a general-purpose speech recognition model trained on a very large, diverse dataset of web audio. Instead of stacking separate acoustic, language and punctuation modules, it treats every speech task as a token prediction problem: transcription, translation, language identification and voice activity detection all share one Transformer encoder-decoder and are distinguished by special task tokens. That single-model design is why a straightforward `pip install` is enough to get multilingual transcription running on a laptop, and why Whisper has become a de facto baseline for open speech-to-text work.

The repository ships six model sizes — tiny, base, small, medium, large and a faster turbo variant — trading accuracy for memory and speed. Each size also has an English-only `.en` counterpart that tends to score better on English audio, while the multilingual checkpoints are the ones to use when translating non-English speech into English. Practical VRAM needs range from roughly 1 GB for tiny up to about 10 GB for large, so the smaller checkpoints run comfortably on consumer hardware or even CPU, while large models are usually paired with a GPU.

Because Whisper is a model and a Python package rather than a hosted product, there is no dashboard, account or quota. You install it, point the command line at audio files, and write your own integration on top. It supports many audio formats through ffmpeg, and its per-language accuracy varies widely — strong for high-resource languages, weaker for low-resource ones — which is worth knowing before adopting it for production transcription.

**Pricing & Plans:** 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.

**Strengths:** 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

**Limitations:** 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
