## Astro (PwC)

Astro is an AI assistant built by PwC for its own people. Rather than a general-purpose chatbot, it acts as an executive concierge embedded in a professional-services environment: it links into the firm's internal systems and answers work-specific questions or performs routine tasks on request.

Interaction is deliberately frictionless. You can type or speak a natural-language request — on desktop or phone — and Astro responds. Typical prompts cover scheduling, time entry, benefits lookups, goal progress and client-relationship intelligence, all using the same conversational interface.

The extension is distributed through the Chrome Web Store and lists more than 200,000 users, which reflects widescale internal deployment at the firm. It is intended for PwC personnel, so its usefulness outside that organization is limited; broader availability of the underlying technology is not advertised.

**Pricing & Plans:** Not publicly priced. Astro is an internal PwC tool distributed to the firm's personnel, so no consumer or per-seat pricing is published on the Chrome Web Store listing.

- **Voice and text requests:** Ask questions or give instructions in plain language by typing or speaking, on desktop or mobile.
- **Firm system integration:** Connects to internal PwC systems so answers and actions reflect real employee data.
- **Day and calendar management:** Check upcoming meetings and stay on top of your schedule with a single question.
- **Time, benefits and goals:** Enter time, look up vacation balances and review progress against revenue goals.
- **Client relationship insights:** Surface who inside the firm has the strongest relationship with a given client.

**Strengths:** Conversational voice and text interface reduces clicks for routine admin tasks; Tight integration with firm systems means answers are grounded in real internal data; Works across desktop and mobile for on-the-go access; Widely deployed, with more than 200,000 users on the Chrome Web Store

**Limitations:** Restricted to PwC personnel, so it is not a general public product; No public pricing or self-serve sign-up for outsiders; Only available in English and limited to the firm's own data sources

## 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
