## HelloDexter (formerly Cerebria)

HelloDexter is a Chrome extension built for sales teams, recruiters and founders who work out of LinkedIn all day. Instead of juggling separate prospecting tabs, it layers contact details directly on top of the LinkedIn interface: when you open a profile you can surface a verified email address, a phone number and social handles, then save the person into your own lead list in the HelloDexter dashboard.

The extension also handles volume work. With a single click it can scrape multiple profiles from a search results or people page and push them into your pipeline, which is useful when you are building a list of a hundred prospects rather than five. An AI writing layer then generates personalized opening messages and follow-ups based on the profile context, so outreach goes out while you are still inside the same tab.

The tool was previously distributed under the name Cerebria, and the Chrome Web Store listing now serves the HelloDexter brand. It stores personally identifiable and authentication information, which the developer states is not sold to third parties. Because it is an independent third-party extension rather than an official LinkedIn product, you should check current data policies and account-safety guidance before scaling any automation.

**Pricing & Plans:** Pricing is not published on the extension listing. The original directory entry listed it as contact-for-pricing, so the practical route is to install the extension or reach the vendor through its sales channel for current plan details. No specific price should be assumed.

- **Inline contact enrichment:** Surface email addresses, phone numbers and social profiles for the LinkedIn contacts you are already viewing, without switching tools or tabs.
- **One-click multi-lead extraction:** Pull multiple profiles from a people or search results page in a single action and push them straight into your saved lead list.
- **AI-personalized outreach:** Generate tailored opening messages and follow-ups from profile context so first-touch emails feel researched rather than templated.
- **LinkedIn-native workflow:** Everything runs inside the LinkedIn interface, keeping prospecting, enrichment and messaging in one continuous flow.
- **Central lead storage:** Valuable contacts are saved to your HelloDexter account so lists survive across sessions and devices.

**Strengths:** Enrichment, extraction and AI messaging live in a single LinkedIn-side extension; Multi-profile extraction saves significant time on list building; AI-assisted personalization keeps outreach from feeling copy-pasted; Lightweight footprint with a small, focused feature set

**Limitations:** Pricing is not published, so cost must be confirmed with the vendor; Small user base and modest review volume, so social proof is limited; As a third-party LinkedIn automation tool, usage carries account-safety considerations

## TinyFish

TinyFish describes itself as the web stack for AI agents: a serverless platform that lets agents search, extract, browse and act on the live web. Rather than a single point tool, it groups several products under one API key and one wallet — TinySearch for fresh, browser-rendered web search returned as structured JSON, TinyFetch for turning any URL into clean Markdown, JSON or HTML, TinyBrowser for real cloud browser sessions driven with Playwright, Puppeteer or CDP, TinyAgent for plain-English multi-step automation, and TinyMonitor for alerts when a page or topic changes.

The platform is aimed at production workloads rather than demos. It emphasises reliability and structure, real browser rendering instead of thin cached results, persistent session state, and the ability to handle authenticated flows. Supporting pieces include TinyVault for connecting 1Password or Bitwarden so credentials stay hidden from the model, TinyProfiles for saving signed-in sessions, and step-by-step run recordings so you can audit exactly what an agent did on a site.

TinyFish is designed to slot into existing developer stacks. It is promoted for use alongside Claude, ChatGPT, Cursor and other agent runtimes, offers an MCP connection, Python SDK and CLI, and is positioned for workloads such as price monitoring, record enrichment, deep research and supplier-portal automation. Entry-level search and fetch calls are free, while agent steps, browser minutes and monitoring checks are metered on a pay-as-you-go wallet basis, with an enterprise track for larger deployments.

**Pricing & Plans:** Freemium and usage-based. Search and basic fetch are free with no search fee, while TinyAgent is billed per step, TinyBrowser per minute and TinyMonitor per check from a prepaid wallet; new users can claim a small free credit. Enterprise plans are custom — confirm current rates on the pricing page.

- **TinySearch:** Real browser-rendered search that returns structured JSON with fresh, uncached results from the live web, with no search fee.
- **TinyFetch:** Convert any URL into token-efficient Markdown, JSON or HTML, stripping navigation bars, cookie banners and ads before they reach your model.
- **TinyBrowser:** Full cloud browser sessions with persistent state that you drive with Playwright, Puppeteer or the Chrome DevTools Protocol.
- **TinyAgent and TinyMonitor:** Give an agent a goal in plain English and it navigates, fills forms and returns structured results; monitoring fires alerts when a tracked page or topic changes.
- **One API key, one wallet:** Search, fetch, browser and agent products share single authentication and billing, plus an MCP connection, Python SDK and CLI.

**Strengths:** Consolidates search, fetch, browsing, agent automation and monitoring behind one API key and wallet; Browser-rendered, uncached results rather than thin cached snippets; Free search and fetch tiers lower the cost per task compared to several paid search APIs; Strong developer ergonomics: MCP, Python SDK, CLI and integrations with popular agent runtimes

**Limitations:** Agent steps, browser minutes and monitoring checks are metered, so heavy automation volumes add up; More complex auth flows still carry the usual fragility of driving third-party sites; It is infrastructure for builders — not aimed at non-technical end users
