## InterSub

InterSub takes the idea of immersion learning and puts it inside the shows you already watch. It is a browser extension for Chrome, Edge, and Firefox that layers two subtitle tracks over the video player: one in the language you are learning and one in your native language. Instead of switching between a video and a dictionary tab, the explanation appears exactly where the problem is.

Hovering over any subtitle word pauses the video and opens a pop-up with an AI-generated definition and a context translation of the words around it. Every lookup is saved to a personal Wordbook together with the sentence it came from, so vocabulary review is built from real scenes rather than generic word lists. The extension also includes an AI Language Buddy tutor that can explain meaning, grammar, and cultural references, and AI subtitle translation for episodes that have no subtitles in your language.

InterSub works across Netflix, YouTube, Prime Video, HBO Max, Crunchyroll, TED, Coursera, Udemy, LinkedIn Learning, Bilibili.tv, and several other platforms, with dozens of language pairs. It also handles study mechanics: a pause-only subtitle mode trains listening, shadowing mode stops after each line so you can repeat it aloud, and a Telegram bot runs spaced-repetition drills on your saved words with Anki sync as an alternative. Dual subtitles themselves are free, with lookups limited each month on the free plan.

**Pricing & Plans:** Free to start with dual subtitles included. The free plan allows a limited number of word lookups each month; Pay-as-you-go and Premium plans add more lookups and unlock AI subtitle translation. Exact prices are listed on the site's plans page.

- **Dual subtitles in your two languages:** Watch with the subtitle of the language you are learning and your native language stacked, one line above the other, directly inside the video player.
- **Hover pop-up dictionary:** Hover any subtitle word and the video pauses while a pop-up shows an AI-generated definition plus a translation of the surrounding context.
- **Self-filling vocabulary builder:** Every word you look up lands in your Wordbook with its original context, so you build a personal list from scenes you actually watched.
- **AI subtitle translation:** If an episode has no subtitles in your language, InterSub translates them on the fly with AI and shows the translation as the second line.
- **AI Language Buddy tutor:** Ask a ChatGPT-powered tutor what a word means in this scene, why the grammar works that way, or what a cultural reference is about.

**Strengths:** Dual subtitles and hover lookups happen inside the player, so you never leave the episode; Vocabulary is captured automatically with the sentence it came from; Supports dozens of language pairs across streaming, learning, and anime platforms; Extra study tools like pause-only subtitles, shadowing mode, a Telegram bot, and Anki sync

**Limitations:** Desktop browser extension only, with no full mobile app; Word lookups are capped each month on the free plan; Requires an internet connection for translations and subtitle synchronization

## Notta

Notta is built around one goal: making sure nothing important said in a meeting gets lost. It can join online calls as a bot, record locally on your device without a bot, capture screen and camera, or simply accept uploaded audio, video and YouTube links. Speech is converted to text in real time or after the fact, with bilingual transcription and on-device options for privacy-sensitive situations.

On top of transcripts, Notta layers AI features that do the downstream work: summaries with action items, cross-meeting Q&A through Notta Brain, bilingual real-time translation, shareable infographics, generated presentations, document creation for PDF, Word and Excel, and follow-up email drafts. It also exposes an MCP server and CLI so AI agents can pull meeting context directly.

Integration and compliance are treated seriously — native connections with Zoom, Google Meet, Microsoft Teams, Webex, Slack, Notion, Salesforce and Google Drive, plus SOC 2 Type II, ISO 27001, GDPR and HIPAA alignment. A generous free tier and modest paid plans make it accessible for individual professionals before scaling to teams.

**Pricing & Plans:** Free plan with 120 transcription minutes per month and full transcription features. Paid Pro plans start around $8.17 per month when billed annually, with higher tiers and enterprise options; a contact-based plan is available for organizations.

- **Flexible recording and import:** Record online meetings with a bot, record bot-free on desktop or mobile, capture screen and camera, or upload audio, video and YouTube links.
- **58-language transcription:** Transcribe and translate in 58 languages, with real-time, bilingual and on-device transcription modes.
- **AI notes and summaries:** Generate summaries, action items and key decisions automatically, then ask questions across all your meetings.
- **Visual and document output:** Turn discussions into infographics, presentations, PDF, Word and Excel documents, and ready-to-send follow-up emails.
- **Integrations and compliance:** Connect Zoom, Meet, Teams, Webex, Slack, Notion and Salesforce, with SOC 2 Type II, ISO 27001, GDPR and HIPAA alignment.

**Strengths:** Reliable transcription with very broad language coverage; Strong privacy and compliance posture including on-device mode; Deliverables go beyond text into slides, infographics and documents; Wide list of native integrations with common business tools

**Limitations:** Free minutes are limited and can run out quickly with heavy meeting loads; AI summary quality depends on audio clarity and speaker separation; Advanced visual and document features are tied to paid tiers
