## Explain Selected

Explain Selected is a lightweight Chrome extension that removes the friction from looking up unfamiliar words while you read. Instead of opening a dictionary tab and scanning through a dozen senses to find the one that fits, you highlight the word or phrase in place and a purple circle appears. One click gives you the definition, the pronunciation and a plain-language explanation written for that specific context.

The distinguishing feature is contextual disambiguation. English is full of words whose meanings have almost nothing to do with each other — the extension's own example is "pounds", which can mean a unit of weight, a verb describing hitting something, or the British currency. Rather than presenting all three blindly, Explain Selected passes the surrounding sentence to ChatGPT and asks it to infer which sense is actually in play, then retrieves the corresponding Merriam-Webster entry and audio pronunciation. It also handles text that no dictionary covers well, such as current slang and narrow technical terminology.

It is aimed at people who read a lot of English online and want to keep their flow: language learners building vocabulary, professionals working through technical documents, and anyone who keeps encountering words with multiple meanings. Useful selections can be saved to a personal list for later memorization, or shared. Two practical caveats from the listing: extensions do not run in tabs that were already open when you installed it, so refresh those tabs first, and no extension works on Chrome internal pages such as the Chrome Web Store itself.

**Pricing & Plans:** Free. The extension is offered at no cost in the Chrome Web Store, with no in-app purchases listed.

- **Context-aware definitions:** ChatGPT infers which sense of a word fits the sentence you highlighted, instead of dumping every dictionary entry at once.
- **Merriam-Webster definitions and audio:** Matching dictionary entries and audio pronunciation are pulled in so you can hear as well as read the word.
- **One-click purple circle:** Select text and click the purple circle that appears — no popup windows, no copy-pasting into a separate tab.
- **Personal saved list:** Add words you want to remember to a personal list so you can review them later.
- **Share with others:** Send individual explanations to friends when a word or phrase is worth passing on.

**Strengths:** Resolves ambiguous words by using the surrounding sentence rather than guessing; Combines AI explanations with established Merriam-Webster definitions and audio; Works inline on any web page with a single click and no context switching; Saving and sharing selections make it useful for building vocabulary over time

## Runway

Runway is an AI research company focused on generative media. Its Creative suite brings video generation, image generation, editing, and audio tools into a single cloud workspace, so individuals and teams can go from an idea to a finished clip without a traditional editing pipeline. Core generation is driven by Runway's own models, and recent generations have pushed on motion realism, prompt adherence, and visual fidelity.

Runway also operates as a platform rather than only a product. The Dev offering exposes its models and models from other labs through a unified API for building media applications at scale. App Studio lets teams assemble custom no-code creative tools inside Runway, and integrations extend the models into environments like Claude Marketplace. Enterprise plans add security, administration, and support for larger organizations.

Beyond media, Runway researches what it calls General World Models — systems that understand the visual world and its dynamics. This research underpins GWM-1 and the Robotics product line, which provides photorealistic simulation for policy inference, offline evaluation, and synthetic data generation. Runway states that more than 60 million creatives have used its tools.

**Pricing & Plans:** Freemium with free trial access plus paid individual, team, and enterprise tiers; enterprise pricing is available on request. API usage and robotics tooling are typically quoted or metered separately.

- **Text and image to video:** Type a prompt or upload a reference to produce short video clips with model options tuned for realism, motion, and prompt adherence.
- **Editing and motion control:** Motion brush, camera controls, inpainting, and frame-level tools let you direct a generation rather than accept the first result.
- **Developer API platform:** Reach Runway's models and third-party models through the Dev platform to build media products and batch pipelines.
- **No-code App Studio:** Build and share custom creative apps inside Runway without writing code, so teams standardize on repeatable workflows.
- **Robotics and world models:** GWM-1 research powers simulation and policy inference for robotics applications beyond media generation.

**Strengths:** Combines strong video models with an editing suite in one workspace; API platform gives developers access to multiple model providers; Actively advancing model quality through published research; Enterprise support, security, and administration available

**Limitations:** Heavy video generation consumes credits quickly and lowers effective output per dollar; Some advanced capabilities are gated behind higher tiers; Model capabilities and interface change frequently, so workflows may need updating
