## 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

## Lyto (Argos)

Lyto has evolved into a product branded as Argos: a Chrome extension and AI assistant that operates inside the browser rather than in a separate chat window. You type an instruction in ordinary language — "fill this form", "pull this table into a spreadsheet", "compare prices across these pages" — and the assistant performs the steps on the live page, requesting data access only for the actions you explicitly ask it to carry out.

Beyond simple page interaction, the tool aims at genuine workflow automation. It can turn on-screen tables into spreadsheet data, loop through research across several websites, and connect with services such as Google Docs, Gmail and Google Sheets so the results land where your work already lives.

A distinctive angle is continuity: tasks can keep running in the cloud, on your own computer, or via a Telegram handoff after you close the tab. That makes it useful for long research jobs you don't want to babysit, while keeping the primary experience anchored in the browser you are already using.

Because the product has changed names and positioning, the exact feature set and paid tiers can shift; check the official site for the current plans before committing.

**Pricing & Plans:** The site presents the assistant with a free entry point and paid tiers; specific pricing was not confirmed during this check, so verify current plans on the official website.

- **Plain-language browser control:** Describe a task in normal words and the assistant performs it on the page you are currently viewing.
- **Form filling and page actions:** Automatically completes forms and carries out repetitive interactions without manual clicking.
- **Table-to-spreadsheet conversion:** Extracts tabular data from web pages and turns it into usable spreadsheet content.
- **Multi-site research:** Gathers answers across several websites in one workflow rather than one tab at a time.
- **App integrations and handoff:** Connects Google Docs, Gmail and Sheets, and can continue running in the cloud, locally, or via Telegram after the tab closes.

**Strengths:** Works inside the browser you already use instead of another separate chat app; Handles concrete page actions such as form filling and table extraction, not just answers; Native integrations with Google Docs, Gmail and Google Sheets; Tasks can keep running after you close the tab via cloud, local, or Telegram handoff

**Limitations:** The product has rebranded, so older Lyto documentation and references may be outdated; Requires granting the extension access to your browsing data to perform actions; Heavier automation tasks depend on stable connections to the services involved
