## Dex by Thirdlayer

Dex is built around the idea that agents fail when they only retrieve facts. Instead of a shallow search layer, Dex assembles two linked memory systems: an Operational Graph that records entities, relationships, timelines and dependencies across your operations, and a Knowledge Manual that holds the judgment layer — priorities, open loops, relationship context, SOPs and operating principles. The manual is explicitly editable and automatically maintained, so you stay in control of what the AI treats as true.

On top of that context, Dex runs autonomous agents that orchestrate across Gmail, Slack, CRM systems and 20+ other tools, triggered by events or schedules. Because it lives in the browser, it can also act directly in the page: navigating tabs, filling forms and completing work where the context already exists. Your operational context is portable too — an SDK and MCP support let you bring it into other agents and workflows.

Dex also improves with use. It learns from your corrections, approvals and repeated patterns. A Dreamer Agent reasons around the clock over new data to spot emerging patterns and keep your knowledge base current, while a Skill Builder Agent proposes custom automations each week based on the workflows you repeat. Typical wins include meeting prep with full history, follow-ups drafted from call notes, task triage that reflects your priorities, and CRM updates without manual data entry. Dex is available on Chrome (with iMessage, Slack and desktop clients listed as coming soon), offers 256-bit encryption, and supports private cloud deployment for teams that need data isolation.

**Pricing & Plans:** Freemium with an onboarding-based entry point. The site invites users to install Dex and then book an onboarding call; the vendor also mentions talking to them about private cloud, which is typically an enterprise conversation. No public price list is published, so check the site for current plan details.

- **Operational Graph:** A living organisational record that organises every message, meeting, deal update and workflow event into entities, relationships, timelines and dependencies.
- **Knowledge Manual:** An editable, automatically maintained layer for priorities, open loops, SOPs and operating principles — the judgment side of your assistant.
- **Autonomous agents:** Agents that orchestrate across Gmail, Slack, CRM and 20+ tools, triggered by events or on a schedule.
- **Browser control:** Dex can navigate tabs, fill forms and complete tasks directly in your browser, cutting context switching.
- **Dreamer and Skill Builder agents:** One reasons 24/7 over new data to keep context current; the other proposes custom automations weekly from your repeated workflows.
- **SDK and MCP access:** Bring your operational context into any other agent, tool or workflow you already use.

**Strengths:** Differentiated memory model that separates factual retrieval from judgment-based reasoning; Browser-first design means it works where your context already lives; Acts as well as answers: agents execute tasks across Gmail, Slack, CRM and more; Context is portable via SDK and MCP rather than locked inside one chat window

**Limitations:** Onboarding is currently invite/call-based rather than fully self-serve; Requires connecting several tools and some ramp-up before the context compounding pays off; No public price list, so budgeting requires contacting the vendor; Some clients (iMessage, Slack, desktop) are still listed as coming soon

## 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
