GoLinks
By GoLinks
GoLinks helps teams find, access, and share workplace knowledge faster by turning long URLs into secure, human-readable go links. With the GoLinks app for Claude, employees can search their company’s GoLinks library, find important resources, and get details about go links without leaving Claude. Ask Claude to look up a go link, search by keyword, summarize what a link is for, review ownership and usage details, or create a new go link for quick access to a resource. GoLinks makes it easier for teams to navigate the apps, documents, dashboards, and information they use every day. Instead of remembering long URLs or searching through multiple tools, employees can simply ask Claude for the go link they need. Go links created by your organization are only accessible based on your workspace permissions, helping keep company resources secure while making knowledge easier to discover. Use GoLinks in Claude to reduce context switching, improve productivity, and give your team a faster way to access trusted workplace resources.

Wordy- Highlight+Annotate Text
By Widget
Read and write anything with AI highlighting that explains difficult words, ideas, arguments, and writing techniques as you go. Paste any passage into the chat and get a clean, readable version with highlights that open simple explanations beside the text. Instead of jumping between search results, dictionaries, and websites, you stay focused on what you are reading. Tap a highlighted phrase to see why it matters, what it means, or how it fits into the bigger picture. The app is built for curiosity. Read literature, history, science, news, speeches, legal writing, essays, research papers, blog posts, and your own drafts. Each annotation is created for the specific passage, so the explanations match the surrounding context instead of giving a one-size-fits-all definition. Highlights can explain: • Vocabulary and unfamiliar phrases • Literary devices and writing techniques • Themes, symbols, and motifs • Historical and cultural references • Character development and motivation • Arguments, evidence, and reasoning • Tone, mood, and style • Grammar and sentence structure • Rhetorical strategies • Important facts and key ideas The reading experience stays simple. The original text remains front and center while annotations appear only where they are useful. Open one note at a time to avoid clutter, or move through every annotation in order. Whether you want a quick answer or a deeper explanation, the information is always close to the text that inspired it. Students can use the app to prepare for class, review assigned readings, or understand challenging passages before discussions and exams. Teachers can use it to explore different ways of explaining the same text. Lifelong learners can finally tackle books and articles that once felt too difficult. Writers and editors can also benefit. Paste your own work into the app to see explanations of structure, language, and rhetorical choices. Use the annotations to spot places where readers may need more context or where a sentence could be clearer. Every passage is different. A line from Shakespeare needs different notes than a scientific article or a court opinion. The app adapts its explanations to the text instead of forcing every document into the same template. Designed with a clean interface, the app keeps reading comfortable on phones and tablets. Text is easy to scan, annotations are easy to open, and the layout keeps your place while you explore each note. Whether you are studying for school, preparing for work, learning a new subject, or reading for fun, the app helps you spend less time searching for explanations and more time understanding what you read. Paste a passage, explore the highlights, and discover more in every paragraph. You decide how much detail you want. Read straight through without interruptions, or pause on any highlight when something catches your attention. Short notes give fast answers. Longer notes connect ideas across the passage and explain why a sentence, quote, or example matters. This makes it easier to build understanding one step at a time instead of feeling overwhelmed. The app works well for homework, book clubs, workplace training, language practice, and personal reading goals. If you enjoy asking questions while you read, this app brings those answers directly into the page. It can help you recognize patterns, follow complex arguments, remember important details, and appreciate strong writing. Features include: • Paste almost any text • AI-generated contextual annotations • Clear highlighted passages • Simple side-by-side explanations • Easy navigation between notes • Clean, distraction-free reading experience • Fast exploration of complex material Understanding starts with context. Instead of reading around confusing parts, read through them with guidance that appears exactly where you need it. Read confidently, stay curious, and turn difficult passages into clear learning every day. today.
