## 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

## Scalebrowser

>Scalebrowser targets the part of agent work that usually breaks first: staying authenticated. Instead of scraping a signed-out page or re-logging in on every run, it hands each agent a browser machine that keeps a stable identity, complete with stored passwords, per-profile inboxes, two-factor codes and passkeys. The product installs as a desktop app so the GPU, screen and fingerprint values match the real machine, which reduces the chance that a profile contradicts itself.

On top of the browser layer, Scalebrowser adds an agent layer. Agents read a page once and then only what changed, which keeps token spend predictable on long runs. Captchas are handled through human-like input, keys on a page are surfaced to the agent as placeholders, and each tool call is logged as a step with a result and a screenshot. It works with MCP clients such as Claude and Cursor, Python and Node SDKs, a REST API and direct CDP for existing browser-use code.

Plans are measured by how much runs at once. The free tier covers a single browser and three profiles, while paid tiers grow concurrent browsers, machines, profiles and workflows. Workflows can be started by hand or by an agent, and higher tiers add schedules, webhooks, sync and phone approvals.

**Pricing & Plans:** Free plan with 1 concurrent browser, 1 machine and 3 profiles, no card required. Paid plans: Start at $19/month (1 browser, 25 profiles), Solo at $49/month (5 browsers, 100 profiles), Studio at $99/month (20 browsers, 3 machines, 500 profiles), and custom Enterprise pricing. Most paid plans include a 7-day free trial.

- **Persistent profile identity:** Each profile is generated from a seed so its identity, cookies and logins persist across restarts, and sites see the same returning visitor rather than a new device.
- **Isolated browser profiles:** One browser per profile means separate logins, cookies and devices that share nothing, making multi-account automation safe to run in parallel.
- **Built-in sign-in and 2FA handling:** Agents get through username and password forms, email confirmation codes, TOTP and SMS two-factor codes, passkeys and permission prompts without stalling.
- **Human-like input and captchas:** Press-and-hold, image grid, slider and rotation captchas are solved through human-like input rather than third-party solving keys.
- **Flexible agent integrations and trails:** Connect over MCP, Python or Node SDKs, REST or direct CDP, and review every action as a step with its result and screenshot.

**Strengths:** Strong focus on persistent, isolated identities so agents stay logged in across runs; Broad integration surface covering MCP, Python/Node SDKs, REST and direct CDP; Built-in handling of logins, email codes, TOTP, SMS, passkeys and captchas; Token-efficient page reading that only reports what changed between steps

**Limitations:** Requires installing a desktop app and running it on your own machine, so it is not a purely cloud-hosted service; Free tier excludes schedules, webhooks, sync and phone approvals; Paid tiers meter concurrent browsers, machines and profile counts, which can raise costs for large fleets; Advanced anti-detection features may raise compliance responsibility with target platforms
