## Merlin AI

Merlin AI lowers the friction of using large language models by putting them where you already are: in the browser sidebar, over the page you are reading. A one-click shortcut summarizes articles, answers questions about a long PDF or YouTube video, drafts a reply in Gmail or LinkedIn, or explains a selection of code, so you avoid copying text into a separate chat window.

Underneath the interface, Merlin routes your prompts across a catalogue of leading models from different vendors instead of locking you into a single provider. Alongside chat, it offers Projects for reusable knowledge bases, Crafts for turning prompts into diagrams and infographics, custom bots with your own instructions, and image generation across many model choices. History, prompts and bots sync across the extension, web app and mobile apps.

The company markets one subscription as a cheaper alternative to buying several model subscriptions separately, with a free tier and a paid Pro plan, and states GDPR, ISO 27001 and SOC 2 compliance. It is a strong fit for people who work mostly inside the browser and want model choice without managing many accounts.

**Pricing & Plans:** Freemium. A free tier covers everyday chats and core extension features; Merlin Pro is advertised at $19 per month billed annually (with periodic promotional pricing such as $2/month offers). Exact limits and current promotions change, so check the pricing page.

- **In-page browser assistant:** A Chrome extension that summarizes, searches and writes directly over the page you are on, without switching tabs.
- **Multiple frontier models:** Access to leading models from several vendors in one place, so you can pick the best fit for each task.
- **Projects and custom bots:** Build reusable knowledge bases from your own documents and code, then query them repeatedly for tailored answers.
- **Crafts visual output:** Turn a prompt into flowcharts, mindmaps, charts and other diagram types for reports and presentations.
- **Sync across devices:** Chat history, saved prompts and custom bots carry over between the Chrome extension, web app, iOS and Android.

**Strengths:** Works inside the browser, so everyday tasks need no tab switching; Several vendor models available under one subscription; Projects, bots and prompt libraries make repeat work efficient; Available in regions where some AI services are restricted

**Limitations:** Free tier is limited, and useful features sit behind Pro; Model availability and tool set change frequently, so behavior can shift; Browser-first design is less convenient for people who prefer a desktop chat client

## Scouter - Language Learning

Scouter - Language Learning is a browser extension built around a simple idea: language acquisition works best when you meet words in real context rather than in isolated vocabulary drills. Instead of copying sentences into a separate study app, you keep reading, watching and browsing, and Scouter breaks down what is in front of you, explains how words behave in that specific sentence, and offers images or dictionary lookups that make the meaning stick.

The extension summarizes webpage content, works with YouTube videos, and accepts custom prompts so you can shape how explanations are produced. Vocabulary you decide to keep goes into Anki in one step, complete with pronunciation, phrase and example sentence, so the bridge between passive exposure and spaced-repetition review stays short. A multilingual interface and one-on-one customer support via its Discord community round out the experience.

Scouter supports a range of model backends, including GPT-4, Claude and locally run Ollama models, alongside free online dictionaries, which lets privacy-conscious users or anyone with an existing API key keep their setup affordable. It is distributed through the Chrome Web Store as a free extension with optional paid capability, and it sits in the language-learning category alongside tools like Lingoku and LiveLang.

**Pricing & Plans:** Listed as freemium on the Chrome Web Store: the extension can be installed at no cost, and paid options unlock expanded usage. Check the extension listing for current tiers.

- **Contextual word explanations:** Understand how a word is used in a specific sentence from the page or video you are reading, rather than relying on a generic dictionary definition.
- **One-click Anki export:** Send words, pronunciations, phrases and full example sentences to Anki without leaving your reading flow.
- **Learn from YouTube:** Watch videos in your target language and pull vocabulary directly from the subtitles and content on screen.
- **Multi-model support:** Choose between GPT-4, Claude, local Ollama models and free online dictionaries, so you can match cost, privacy and quality to your needs.
- **Custom prompts:** Define your own instructions for how explanations and summaries are generated, tailoring the study method to your level and goals.

**Strengths:** Fits into reading and video watching instead of adding a separate study session; Direct Anki integration with pronunciation and example sentences; Choice of GPT-4, Claude, Ollama or free dictionaries; Actively maintained extension with a public update history

**Limitations:** Requires Anki for the full spaced-repetition workflow; Advanced usage depends on bringing your own model access; Available only in Chrome, so Safari and Firefox users are left out
