What if your AI assistant didn’t just help you brainstorm who to sell to, but could actually help you find the right prospects, research them, and turn that research into personalized outreach?
That is the idea behind the Seamless.AI apps for ChatGPT and Claude.
Seamless.AI has expanded its AI ecosystem so that sellers, business owners, marketers, and go-to-market teams can bring Seamless sales intelligence into the AI platforms people already use.
Instead of jumping between an AI assistant, a prospecting platform, spreadsheets, and outreach tools, users can write a prompt inside ChatGPT or Claude and use Seamless.AI data to move from an idea to actionable sales intelligence.
In this article, we’ll share more about the new Seamless ChatGPT and Claude apps, as well as our MCP (Model Context Protocol) server, and how you can get started driving Seamless leads in your favorite chatbot.
Seamless originally launched its MCP server back in July so you can access the platform’s sales intelligence from the AI tools they’re already using and prospect smarter.
MCP is an open standard designed to connect AI applications with external tools and data. And for our engineering team, this innovation opened an important door.
Instead of having to run every AI workflow inside a traditional sales platform, Seamless and all its features could be accessible wherever a seller preferred to work, including ChatGPT, Claude, and other MCP-compatible clients.
But MCP was just the beginning.
The next evolution is making those connections significantly easier for everyday users to enable.
That is where the Seamless.AI ChatGPT and Claude apps come in.
Rather than thinking about endpoints, servers, API keys, or technical configuration, users can bring Seamless’ data and automation into an app they already use and get their prospecting done with a prompt.
For sales teams spending more and more of their workday inside ChatGPT or Claude, that eliminates an enormous amount of context switching.
With Seamless.AI’s B2B sales intelligence available right inside ChatGPT, a typical workflow might look like this:
A salesperson describes exactly who they want to reach.
For example:
“Find 500 CFOs at technology companies in San Francisco with 100 to 1,000 employees that raised a Series B greater than $50 million, then create a personalized seven-day, three-email campaign.”
Instead of running a contact search in app, manually selecting several individual filters, conducting research, locating contact info, and then writing outreach one prospect at a time, Seamless ChatGPT will do all that work for you in a single prompt.
With Seamless ChatGPT, users can:
Just describe the outcome you want, and Seamless ChatGPT will make it happen.
The Seamless ChatGPT app is fantastic for anyone who lives on the chatbot…
A founder working through a go-to-market strategy can move directly from defining an ICP to researching prospects.
An SDR can ask for decision-makers matching specific criteria.
A RevOps or marketing professional can use more sophisticated prompts to explore a total addressable market, segment accounts, or build campaign audiences.
The prompt you write and the conversation you have are the starting points, while Seamless provides the sales intelligence to execute real prospecting.
In addition to ChatGPT, Seamless is also live in Claude's public directory. This means Claude users can discover and add Seamless without configuring a custom connector or manually entering an MCP server URL.
That turns what began as an infrastructure-level MCP connection into a much more accessible workflow for the average Claude user.
Similarly to ChatGPT, when Claude users connect Seamless, you can:
With Seamless ChatGPT and Claude, the biggest advantage is the time these connections eliminate between thinking about a sales task and executing the sales task.
Consider a traditional prospecting workflow where a rep might:
Each of these tasks traditionally takes time and runs the risk of information getting lost between tools. But with Seamless inside ChatGPT and Claude, you can hit these steps in a single prompt.
Now that you can get the world’s ChatGPT and Claude, which one do you choose? Well, it depends on where you’ve already built your daily workflow.
Some execute their prospecting with ChatGPT. Others might come up with GTM plays using Claude and several other apps.
Because the Seamless ecosystem is built around interoperable AI connections, users have more freedom to work from the app that fits them best.
That same philosophy of choosing what works best for your team also extends to AI Fields. Users can select Claude models like Claude Opus or Claude Sonnet, along with GPT models, when configuring supported AI Fields.
So instead of forcing every AI-powered task through one model, the Seamless ecosystem allows you to take a more flexible approach to sales intelligence.
Over the years, we’ve seen the release of several apps, and we’ve seen the average seller’s tech stack grow to unmanageable sizes.
But AI creates an opportunity to eliminate some of that fragmentation.
If a rep is already using ChatGPT to prepare for meetings or think through territory strategy, they shouldn't necessarily have to abandon that workflow when it's time to find the actual people they want to contact.
Likewise, someone who works primarily in Claude shouldn't have to move into an entirely separate workflow simply because their research has turned into prospecting.
Connecting Seamless directly to those apps solves this problem and makes the data accessible at the moment it is needed. That means fewer tabs, fewer disconnected workflows, and a much shorter distance between an idea and a customer.
The Seamless MCP server established the foundation for connecting sales intelligence with the rapidly expanding AI ecosystem.
Now the Seamless.AI apps for ChatGPT and Claude make that vision much easier to use.
The AI assistant where you research a market, develop an ICP, plan a campaign, or prepare for a sales call can also connect with the sales intelligence needed to put those ideas into action.
For sellers and marketers already working natively in ChatGPT or Claude, that changes what an AI conversation can become.
Don't just ask AI who to sell to. Use Seamless to start finding them.
If you’re a Claude user, add Seamless from the Claude directory and connect your account to begin using Seamless in your Claude workflows.
And if ChatGPT is more your speed, connect Seamless to ChatGPT and use natural-language prompts to begin building prospecting workflows.
