## AIPex

AIPex targets the friction that comes with the current crop of AI-native browsers: to get AI automation you normally have to abandon your current browser, re-import your bookmarks, and rebuild your extension stack. AIPex refuses that trade-off. It is a Chrome extension that attaches an AI agent to the browser you already run, so setup is a matter of seconds and nothing you have configured is lost. The free core is open source, and the project has built a visible community around it, with thousands of GitHub stars and tens of thousands of active users reported on the site.

The assistant covers day-to-day browsing chores and deeper automation alike. It groups and organizes tabs by topic or project, lets you converse with your open tabs to summarize or extract information, runs multi-source research, and can drive pages through natural-language commands instead of brittle scripts. A separate but related capability turns observation into output: AIPex can watch a session and produce step-by-step user manuals, product demos, bug reports, or customer-support articles from what it saw, which makes it useful well beyond lightweight browsing.

Pricing follows a credits model. There is a free open-source tier, and paid plans — Basic at $20/month, Pro at $60/month, and Business at $100/month — convert the fee into monthly credits that can be spent across the supported AI models, with unlimited @tabs usage and, on higher tiers, advanced agent features and team collaboration. Because it is a third-party extension rather than a vendor-operated AI browser, users should treat it as an independent product with its own privacy and data policies.

**Pricing & Plans:** Free and open source at the core. Paid plans are credit-based: Basic $20/month, Pro $60/month, and Business $100/month, each granting an equivalent amount of monthly AI credits, unlimited @tabs, and tier-dependent extras such as advanced agent features and team collaboration.

- **Zero-migration browser automation:** Works as an extension inside your existing Chrome browser, so your bookmarks, extensions, logins, and settings stay exactly where they are.
- **Natural-language control:** Ask the assistant to organize tabs, summarize pages, fill forms, or run multi-step tasks without writing scripts or automation code.
- **Chat with your tabs:** Interact with open tabs conversationally to ask questions across pages, pull out details, or synthesize information from several sources at once.
- **Observation-to-documentation:** Turns recorded browsing and screen sessions into step-by-step guides, product demos, bug reports, and support knowledge-base articles.
- **Privacy-first and open source:** The core extension is open source and designed to keep automation running locally in your own browser session rather than through a forced vendor browser.

**Strengths:** No browser migration: it augments Chrome rather than replacing it; Free and open-source core with a public GitHub repository; Broad capability set spanning tab management, scraping, and documentation generation; Transparent credit-based pricing that scales from individual to team use

**Limitations:** Paid plans are credit-metered, so heavy AI usage costs can add up; Limited to Chromium-based browsers rather than being cross-browser; Advanced agent features sit behind the higher-priced tiers

## 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
