The ten best connectors, skills and plugins for your AI and your job, with setup steps. 382 tools reviewed, all from official directories.

How we choose. Every tool here is listed in its platform's official directory or published by the AI company itself, and has a public signal behind it: install counts, GitHub stars, ratings or verified status. We rank by quality first, then by how closely it fits your search. Directories change weekly, so check permissions before you connect anything to company data. Last reviewed November 2026.
The AI Tool Finder picks the ten best add-ons for the AI you already use. Choose Claude, ChatGPT or Perplexity, then type your job, what you want to make, or both. It ranks 382 connectors, skills, plugins, MCP servers, GPTs and Spaces from official directories by quality and fit, and shows how to set each one up.
Every AI assistant now has an app store of sorts. Claude has connectors, skills and plugins. ChatGPT has plugins, apps and custom GPTs. Perplexity has connectors, Spaces and skills. Between them that's hundreds of add-ons, and the official directories sort them alphabetically or by popularity, not by the job you actually do. The finder sorts them by your job instead.
382 tools across the three assistants most UK businesses use, all listed in an official directory or published by the AI company itself.
178 tools, the largest set, led by third-party connectors.
108 tools, mostly plugins from OpenAI's Plugin directory.
96 tools, with connectors for Perplexity Computer plus Spaces.
It matches against 25 jobs, from accountants, solicitors and estate agents to teachers, tradespeople and charities, and 33 things you might want to make, from presentations and spreadsheets to grant bids, brand guidelines and online shops. Anything else you type is matched on your own words.
Link your AI to another app, such as Google Drive, Outlook, Slack, Xero or HubSpot, so it can search, read or act on your data there.
Packaged instructions and files that teach the AI one job, such as producing a proper Word document, Excel model or slide deck.
Bundles of skills, connectors and commands built for a role or workflow, like finance, legal, sales or marketing.
The Model Context Protocol is the open standard most connectors are built on. An MCP server exposes a tool or data source to the AI.
Versions of ChatGPT set up with their own instructions and knowledge for one task, shared through the GPT Store.
Perplexity's project folders: a shared set of files, instructions and searches that keep research on one topic in one place.
Every tool is listed in its platform's official directory or published by Anthropic, OpenAI or Perplexity, and has a public signal behind it: install counts, GitHub stars, ratings or verified status.
Each tool has a quality score from one to five. The finder ranks by quality first, then by how closely the tool fits your job and your output. A tool that matches both gets a big boost, and no single type can take more than six of the ten places, so you see a useful mix.
Some jobs only have a handful of purpose-built tools on a given platform. When that happens, the finder fills the list with built-in features that work for almost any job, marks them General pick, and suggests comparing another AI in step 1.
The question I get asked most in training sessions isn't "which AI should we use?" any more. It's "what should we plug into it?" People open a connector directory, scroll past a few hundred logos and close it again. Or they install everything and use nothing.
So I built the list I wish I could hand people: the tools worth trying first, sorted by the job you do, with the setup steps written out. It's deliberately short. Ten good tools that you'll actually use beat a hundred that sit there with access to your inbox.

A free tool from The Oxford AI School that recommends the ten best connectors, skills, plugins, MCP servers, GPTs and Spaces for Claude, ChatGPT or Perplexity. You choose your AI, then add your job, what you want to make, or both, and it ranks 382 tools from official directories by quality and fit, with setup steps for each.
Yes. There's no sign-up and no email wall, and nothing you type leaves your browser, because the matching runs on your device. Some of the tools it recommends are free and some need a paid plan on Claude, ChatGPT, Perplexity or the connected app.
A connector links your AI to another app, such as Google Drive, Slack or Xero, so it can read or act on your data there. A skill is a packaged set of instructions and files that teaches the AI to do one job well, like building a PowerPoint deck. A plugin bundles several skills, connectors and commands for a role or workflow.
MCP stands for Model Context Protocol, an open standard for connecting AI assistants to tools and data. An MCP server is the piece that exposes a tool, such as a database or a design app, to the AI. Most people meet MCP through ready-made connectors rather than setting up servers themselves.
Of the 382 tools in the finder, 178 are for Claude, 108 for ChatGPT and 96 for Perplexity. Claude has the most third-party connectors, ChatGPT leans on plugins and custom GPTs, and Perplexity mixes connectors with Spaces and skills. The best choice is the AI your team already uses well.
It can be, if you check first. Look at what permissions the connector asks for, whether your plan keeps your data out of model training, who in the business approved it, and whether the tool is from the official directory or a verified publisher. Start with read-only access and one low-risk workflow.
The directories behind it change weekly, so the list is reviewed regularly. It was last reviewed in November 2026. If a link has moved or a tool has gone, the platform's official directory is always the source to trust.
