Generative AI has completely changed how we approach work, especially in sales.
If you’re in a role where time is money, you’ve probably already seen how much AI can help with daily tasks.
But as handy as it is, there’s a point where the constant back-and-forth—uploading the same reference files, repeating the same prompts, explaining the same context—starts feeling like a chore. That’s where custom AI assistants come in.
Think of them as your personal team of AI interns, always ready, never tired, and trained specifically to help you with the parts of your job that keep repeating. Whether you’re setting up sales calls, qualifying leads, sending follow-ups, or building pitch decks, training AI bots the right way can help you make that workflow smoother, faster, and a whole lot easier.
What Is an AI Sales Assistant?
So let’s kick things off with a simple definition. What exactly is an AI sales assistant?
In short, it’s a digital helper built on artificial intelligence that supports salespeople with their day-to-day work.
These assistants can run on large language models and other AI tools that handle text, speech, data, and predictions. And while the tech behind it might sound complex—think machine learning, NLP, predictive algorithms—it’s really just about saving time, reducing busywork, and making better sales decisions.
You might hear them called different things:
- Virtual sales assistants
- AI-powered sales assistants
- AI virtual sales assistants
- Guided selling tools
All of these fall under the same umbrella: digital assistants that support the sales process from prospecting to close.
Some help with repetitive tasks like scheduling meetings, entering CRM data, or sorting leads. Others go deeper—sourcing prospects, preparing for calls, identifying objections, summarizing meetings, or suggesting next steps.
The best ones learn as they go, getting smarter with every interaction.
Why Are AI Sales Assistants Getting So Popular?
The reason so many revenue teams are getting serious about AI sales assistants comes down to one thing: impact.
Sales reps are stretched thin. Between keeping CRM data up to date, following up with leads, researching prospects, writing emails, sitting through meetings, and putting together reports—it’s easy to get buried. AI sales assistants are designed to lift some of that load.
When the assistant handles the admin work, reps get more time to actually sell.
And because the AI is trained on best practices, it helps guide decisions in real time. Instead of guessing the next move, reps can act based on solid data.
That’s why training AI bots well is so important. A generic AI tool can only take you so far. But when it’s trained on your sales process, your customers, your tone of voice—it becomes a real asset. We’re not just talking about convenience. We’re talking about reps closing more deals, faster.
The Difference Between Conversation Intelligence and AI Sales Assistants
There’s another term that gets thrown around in the same breath as AI sales assistants: conversation intelligence.
They’re closely related, but not quite the same.
Let’s break that down a bit.
What Is Conversation Intelligence?
Conversation intelligence tools record, transcribe, and analyze sales calls. Their goal is to extract insights from every customer interaction.
Tools like Trellu’s Call AI will look at:
- How questions are asked and answered
- The overall tone or sentiment of the call
- Filler words and talk-to-listen ratio
- Pain points, objections, or competitor mentions
Conversation intelligence gives a deep look into how reps are communicating, what’s working, and where there’s room to improve.
What Makes Trellus’s Conversation Intelligence Different?
As we’ve always mentioned in our earlier posts, Trellus took off as a simple dialing solution for outbound sales businesses.
Over time, and seeing to the demand factor, we pivoted our focus on adding more to the platform to make it come off as a complete end to end experience for kicking a live sales floor to the next level.
From calls point of view, we’ve introduced parallel dialing that supports 5 calls simultaneously, and plenty of other things.
Now the interesting part is conversation intelligence - a fundamental part of everything we do here.
Our conversation intelligence tech is based on machine learning and natural language processing algos. So, this sets Trellus apart from your usual ai conversation platforms out there on the internet.
The ai agent, as we like to call it, picks up on ongoing live calls’ conversation patterns and suggests cues based on areas where your sales or support time might be lacking. This is one of the best use cases where conversation intelligence is put to use, in real time, to help improve conversational skills.
Moving on, as other aspects of ai sales assistance work, there are features that throttle sales enablement to the next level. We’re talking about:
- AI Training Bots For Sales Teams
Warm up your conversational muscles with a practice session before hitting the phone to make every live conversation count. Crack challenging bots to develop new skills and expand your comfort zone.

More To Know About AI Sales Assistant?
Think of conversation intelligence as a specialist. It’s focused on analyzing what’s happening in your calls.
On the other hand, AI sales assistants act more like generalists. They can support reps before, during, and after a call. Scheduling, research, writing, summarizing, follow-up—they’re there for the entire journey.
In fact, when you combine conversation intelligence with a well-trained AI assistant, that’s when things really click. You’ve got insight plus action, and that’s a winning combo.
Key Areas Where AI Assistants Really Shine
Training AI bots to help in sales isn’t just about automating small tasks.
It’s about giving reps a toolkit that supports them across everything they do. Let’s walk through a few key areas where custom AI assistants are starting to shine.
1. Writing, Content, and Communication
Sales involves a lot of writing—emails, LinkedIn messages, call follow-ups, sales decks, proposals, and more. If each one has to be written from scratch, it’s easy to fall behind.
This is where training AI bots becomes a game-changer. You can create a sales assistant that knows your brand voice, understands what makes a good cold email, and can whip up templates based on different buyer personas or industries.
Once you’ve trained your assistant on your tone and examples, you can just say something like, “Write a follow-up email for a B2B SaaS lead that ghosted after the second call,” and the assistant will handle it in seconds.

2. Troubleshooting and Technical Help
Tech stacks in sales are getting more complex. Between CRMs, sales enablement tools, analytics dashboards, and automation software, things break or get confusing. Fast.
You can train AI bots to act as internal troubleshooters. Give them documentation about your tech setup, tool stack, and common issues, and they can guide reps through solutions without involving the IT team every time.
That applies to customer support, too. AI bots trained on product documentation can handle routine questions so customer-facing teams can focus on more complex issues.
3. Productivity and Project Support
Sales isn’t just about calls and deals. It’s projects, planning, and prioritization, too. That’s where AI assistants can step in as project managers.
They can:
- Extract action items from meeting notes
- Send reminders
- Help with time blocking
- Track goal progress
- Generate status updates
With new tools coming out that let AI interact with calendars, task managers, and docs, we’re not far from having bots that not only remind you about a follow-up but book it for you too.
4. Coaching and Strategic Thinking
AI assistants can also act like coaches. With the right prompts and feedback, they can simulate coaching conversations, give feedback on pitches or emails, or help work through strategy.
Want feedback on a proposal? Feed it to your assistant. Need help prepping for a negotiation? Ask the bot to act like a tough buyer. These assistants can be configured to match different personalities or coaching styles—from kind and encouraging to brutally direct.
Training AI Bots: How to Do It Right
Let’s say the goal is to build your own AI sales assistant. Here’s how to get started without overcomplicating things.
Step 1: Pick a Platform
There are plenty of tools out there. ChatGPT calls them “Custom GPTs,” Claude has “Projects,” Gemini uses “Gems.”
The right platform depends on what you need:
- Want a more natural, chat-like assistant with voice interaction? ChatGPT is a strong pick.
- Need help with writing or editing? Claude does a great job capturing tone.
- Already working in Google Docs or Gmail? Gemini can pull in those assets easily.
Each has strengths. Some have live web access, some don’t. Some keep conversations private, others don’t. It’s worth comparing based on what matters to your workflow.
Step 2: Test Things Out Against Your Baseline Requirements
Before locking anything in, start with some test prompts. Treat it like a new hire—you want to see how it handles tasks and give clear, specific feedback.
For example:
“Write a cold email for a healthcare tech company. Keep it under 100 words. Add a soft CTA and sound confident, but not aggressive.”
If the output misses the mark, don’t just say “wrong.” Point out exactly what worked and what didn’t. Maybe the tone was off, or the CTA was too pushy. Clear feedback helps shape better responses next time.
Once you’ve got a few solid back-and-forths, ask the AI to summarize what it’s learned. That’ll give you a base set of instructions to build your assistant.
Step 3: Draft the Instructions
The core of a custom AI assistant is the instruction set. That’s where you define:
- The assistant’s role
- Its personality
- Its goals
- The kind of output it should produce
- The tone it should use
Let’s say you’re building an assistant to help write outreach emails. Your instructions might say:
“You are a B2B sales copywriter who specializes in short, punchy emails. You write with a confident but warm tone. Every email should aim to start a conversation. Your goal is to increase open and response rates. Avoid clichés and buzzwords.”
The more specific the instructions, the better the assistant performs.
Step 4: Narrow the Focus
It’s tempting to make one big super-assistant that does everything. But often, the best results come from breaking things down into smaller bots.
Instead of one assistant for all of sales, build:
- One for email outreach
- One for call prep
- One for CRM updates
- One for sales enablement materials
Each one can be fine-tuned to do its job really well, instead of being okay at everything.
Wrapping It Up
The promise of AI in sales isn’t just about cool tech. It’s about making life easier for sellers and helping them focus on what really moves the needle: connecting with customers and closing deals.
But the magic doesn’t happen automatically. It takes thought, experimentation, and some effort training AI bots so they actually understand the task at hand.
Done right, a well-trained AI sales assistant becomes more than just a helper—it’s a force multiplier. Reps move faster, stay focused, and work smarter. Conversations get better. Results get better. The whole sales process becomes more human, not less.
And isn’t that the goal?
