## Merlin AI

Merlin is built around a simple idea: instead of opening a separate chat tab for every task, you summon one assistant with a click while staying inside whatever you are reading or working on. The extension injects a sidebar on any web page, so it can read the article, the PDF, the YouTube transcript or the Gmail thread you currently have open and respond with that context already loaded. That makes summarization, rewriting, replying and research feel like part of the page rather than a separate tool.

Under the hood Merlin routes requests across a broad set of models — OpenAI's GPT family, Anthropic's Claude, Google's Gemini, DeepSeek, Mistral, Meta's Llama and others — so you can pick the model that suits a task without holding separate subscriptions for each. Beyond chat there is an image generator with multiple models and aspect ratios, a search mode that answers questions from live web results, document and video summarization, and a library of saved prompts. Newer additions like Projects (reusable knowledge bases) and Crafts (generated diagrams, mind maps and charts) push it toward light research and prototyping work.

Merlin is available as a Chrome extension, a web app, an iOS app and an Android app with synced history, custom prompts and custom bots across devices. The vendor highlights GDPR, ISO 27001 and SOC 2 alignment for data handling, and positions itself as accessible in 200+ countries where some other assistants are restricted. It is squarely a productivity assistant rather than a developer platform.

**Pricing & Plans:** Freemium. A free tier covers everyday use, and Merlin Pro is promoted at $2/month as a special offer, with the standard plan advertised around $19/month billed annually and described as replacing roughly $130/month of separate AI subscriptions. Paid tiers add higher limits, more capable models and advanced features.

- **Multi-model access in one place:** Switch between GPT, Claude, Gemini, DeepSeek, Mistral and Llama class models from a single interface instead of juggling separate subscriptions.
- **Universal page summarization:** Summarize articles, YouTube videos, PDFs and documents in place, then ask follow-up questions grounded in that content.
- **Writing and social drafts:** Draft and reply to emails in Gmail, compose posts and comments for X and LinkedIn, and repurpose web pages or videos into blogs and articles.
- **Image generation:** Generate images from prompts using more than 20 image models and multiple aspect ratios for web and social output.
- **Projects, Crafts and custom bots:** Build reusable knowledge bases, generate diagrams and charts from a prompt, and assemble custom chatbots from your own instructions and context.

**Strengths:** Replaces several separate AI subscriptions with one interface and one bill; Works inline on any page, so context is captured without copy-pasting; Covers a wide range of tasks: chat, summarization, writing, images, search and light research; Syncs across browser, web, iOS and Android with custom prompts and bots preserved

**Limitations:** The free tier is limited, and heavy use pushes you toward the paid plan; Covering so many features means individual tools may be less deep than dedicated apps; Requires trusting a third party with the pages and documents you send it, even with the stated compliance certifications

## PixieBrix

PixieBrix began as a low-code way to customise web applications in the browser and has grown into an enterprise security and productivity platform. Its core product is the VIA Extension, a managed browser extension that brings Secure Enterprise Browser controls to Chrome, Edge, Island, Prisma and other Chromium browsers — without asking the workforce to migrate to a new browser.

The value proposition is workflow-level visibility and control. Network-based tools see traffic, while system logs record what happened around an action; PixieBrix focuses on the action itself inside the browser. That includes click and field-edit context, cross-tab interaction matching for dynamic authorisation, and the ability to monitor or block the same actions whether a human or an AI agent performs them.

The platform is particularly strong in contact centres and other high-volume front-line environments, where it targets revenue leakage from off-policy refunds and discounts, account abuse, fraud patterns such as reused shipping addresses and loyalty-point theft, and last-mile data loss through copy, paste and typing. It deploys in days rather than months, works on any OS including Chromebooks, and integrates with more than 3000 APIs.

**Pricing & Plans:** PixieBrix uses per-user subscription pricing with monthly or annual billing. Starter is aimed at small teams, Business adds AI/low-code custom controls, 3000+ API integrations, an MCP investigation server and SIEM integration, and Enterprise adds SSO, audio capture, white-labelling and support SLAs at custom pricing. Enterprise customers can request a free sandbox to evaluate technical controls.

- **Secure Enterprise Browser via extension:** PixieBrix deploys as a managed extension to monitor human and AI actions in any web app — including third-party sites — with full browser context that network controls miss.
- **Real-time policy enforcement:** Configure group policies in minutes to monitor, warn, soft-block or block actions, with built-in contact-centre and anti-fraud controls plus AI-code and low-code custom controls.
- **Revenue protection and audit:** Cover refund and discount integrity, shipping and loyalty fraud, payment-card masking, and flag snooping, bulk exports and after-hours activity.
- **Audit logs and investigations:** Every browser action is logged with on-screen context, backed by user risk scoring and an MCP investigation server for correlating data sets.
- **3000+ API integrations:** Connect to over 3000 APIs — chat, spreadsheets, project management, CRM — or define your own integration with any REST API.

**Strengths:** Protects where work actually happens, in the browser, without a new browser deployment; Covers both human and AI agent actions across third-party web apps; Fast deployment in days on any OS, including Chromebooks; Built-in contact-centre and anti-fraud controls plus custom low-code authoring

**Limitations:** Pricing is per-user and oriented to teams, so solo users are not the target; Starter plan excludes the no-code custom controls and 3000+ API integrations; Deployment requires browser extension management across the organisation; Enterprise pricing is quote-only
