## Manus

Manus positions itself as an "action engine" rather than a chatbot. You describe an outcome, and the agent breaks it into steps, decides which tools to use, browses the web when it needs current information, and assembles the final deliverable in a cloud sandbox. Typical outputs include presentation decks, working websites and small games, generated images and video, and long-form research reports assembled through its Wide Research workflow.

The product ships as a mobile app (iOS and Android), a desktop app, and a browser extension, plus a web console with an API for programmatic use. A Slack integration lets teams dispatch tasks from chat, and workspace features such as team plans and SSO make it viable inside organizations rather than only for individuals. Because the agent runs asynchronously, a common pattern is to queue a task, walk away, and review the result later.

Pricing combines a free trial-style entry point with paid subscription tiers and a business plan; exact credit allowances and seats change over time, so confirm current terms on the official pricing page. The obvious trade-off is control: autonomous agents can misread intent or burn credits on the wrong approach, so clear briefs and intermediate review matter.

**Pricing & Plans:** Free trial available, with paid subscription tiers and a business plan for teams and higher usage. Credit allowances and seat details change, so check the official pricing page.

- **Autonomous task execution:** Give the agent a goal and it plans the steps, chooses tools, and works through the task in a cloud environment without constant supervision.
- **Deliverable generation:** Produces finished artifacts such as slide decks, functional websites, small games, and formatted documents rather than raw text.
- **Wide Research:** Runs broad, multi-source investigations and compiles the findings into a structured report.
- **Media creation:** Generates images, video, and music as part of a larger task or as standalone outputs.
- **Integrations and API:** Connects to Slack for task dispatch, offers mobile and desktop apps, and exposes an API for embedding agent work in your own stack.

**Strengths:** Delivers finished artifacts instead of only conversational answers; Works across web, mobile, desktop, Slack, and API surfaces; Wide Research handles broad multi-source investigations well; Team plans and SSO make it usable in organizational settings

**Limitations:** Autonomous runs consume credits and can pursue the wrong approach if the brief is vague; Complex tasks benefit from human review at checkpoints; Output quality varies by task type, especially outside common formats

## WebextLLM

WebextLLM was created as the first extension to embed large language models inside the browser itself. Rather than forwarding your text to a cloud endpoint, it ships the models with the extension and runs them in an isolated environment, so the only thing needed to start chatting is the browser you already have. That design removes configuration, accounts and API keys from the setup entirely.

The extension doubles as an app platform. Through the window.ai interface, websites and other extensions can request access to the locally hosted model, letting developers build AI features on top of a runtime that lives in the browser. A permission layer shows you which applications are asking for access and lets you grant or deny it, alongside a history of the prompts and responses exchanged with your model.

Because the model runs on your hardware, WebextLLM is free to use, private and effectively unlimited, and it keeps functioning without an internet connection. The developer is candid that it is an experimental proof-of-concept rather than a production tool, and warns that risks such as data loss or system issues are assumed by the user. It is best treated as a hands-on way to explore browser-native AI and the emerging window.ai ecosystem.

**Pricing & Plans:** WebextLLM is completely free. There is no subscription, no token billing and no usage cap, because inference runs on your own hardware. You only need Chrome and enough local resources to run the bundled models.

- **Browser-native local inference:** Large language models are packaged inside the extension and executed in an isolated browser sandbox, so no server, account or API key is required to get started.
- **Private and offline by default:** Every request is served from your own machine, which keeps your prompts and data off third-party servers and lets the tool keep working when you are offline.
- **window.ai app ecosystem:** Websites and extensions can request access to your model through the window.ai interface, turning the browser into a shared AI runtime for web apps.
- **Granular permission control:** You decide which applications are allowed to talk to your model, and you can review the history of prompts and responses made across different apps.
- **No quotas or token fees:** Own the model outright and run as many requests as your hardware allows, with no quotas, throttling or content limits imposed by a provider.

**Strengths:** Completely free with no subscription, tokens or quotas; Runs entirely on-device, so conversations stay private and work offline; Zero configuration, accounts or API keys required; Open window.ai interface lets web apps tap into a browser-native LLM

**Limitations:** Marked as an experimental proof-of-concept and explicitly not recommended for production use; Last updated in October 2023, so it may lag behind current browser AI standards; Limited to a small catalog of bundled models and requires decent local hardware; Small user base, so community support and documentation are thin
