Explainer videos have become one of the most effective ways for businesses to simplify complex ideas, introduce products, and guide customers through decisions. An explainer video is a short, structured piece of content that clearly communicates what something is, how it works, and why it matters, making it a go-to asset for marketing, sales, customer experience, and even learning teams.
But the way organizations create explainer videos has changed dramatically. In 2026, teams don’t have the time, budget, or production resources required for traditional video methods. They need content that’s fast to produce, easy to update, and consistent across every audience and channel.
That’s why the best 2026 explainer videos are built using three essential components: AI avatars, video templates, and AI voices. These elements dramatically reduce production time while ensuring clarity, brand consistency, and relevance, no matter who’s creating the content.
This post breaks down each must-have, why they matter, and how modern teams can combine them into a scalable explainer video workflow.
What’s trending in 2026 explainer videos
Across the marketing, sales, and customer experience landscape, a few trends are reshaping how teams think about explainer content:
- Demand for clarity: Audiences want short, digestible explanations, not long-form text or dense decks.
- Rise of self-service: CX teams are increasingly relying on video to reduce repetitive inquiries.
- Sales acceleration: Reps now use video throughout the sales cycle—prospecting, demo recaps, proposals, QBR summaries.
- Faster content cycles: L&D and internal comms need onboarding and policy videos that can be updated instantly.
- Brand consistency pressure: Distributed teams are creating more content than ever, making governance essential.
These requirements point to one clear direction: AI-assisted explainer videos built on a repeatable foundation.
Must-have #1: AI avatars
AI avatars have become mainstream in 2026 because they remove one of the biggest bottlenecks of video creation: the need to film content.
Why AI avatars matter
AI avatars enable:
- On-camera delivery without cameras
- Professional, consistent video talent
- Instant updates without reshoots
- Localization across dozens of languages
- Scalable internal and external communication
For global organizations, especially in financial services, healthcare, insurance, and technology, this consistency is invaluable.
The rise of Custom AI Avatars
Custom AI Avatars take this capability even further. Instead of relying solely on stock or generic avatars, organizations can now create a lifelike AI version of a real employee—an executive, a product expert, a trainer, or a sales leader—without requiring them to record new footage every time.
This is especially powerful for explainer videos, where trust, familiarity, and clarity matter. A Custom AI Avatar lets teams:
- Deliver content through a recognizable company voice or face
- Scale executive communication without scheduling real filming
- Update messaging instantly while retaining authenticity
- Support multilingual communication using the same familiar spokesperson
- Create explainer videos that feel personal, credible, and connected to the brand
For example, a product leader can “host” every product walkthrough, or a CX leader can appear in onboarding and support explainers without ever needing to record a new video.
This blends the best of brand consistency with true human presence, making Custom AI Avatars an ideal choice for high-volume explainer content across marketing, CX, and sales.
Where AI avatars excel
- Product explainers: feature walk-throughs, updates, release notes
- Onboarding videos: for customers or new employees
- Support content: troubleshooting, step-by-step guidance
- Sales follow-ups: demo recaps, proposal walkthroughs
For teams producing high volumes of repeatable content, avatars ensure professionalism without slowing production.
Must-have #2: Video templates
Video templates are pre-created video content for a specific use case, fully branded and controlled via brand governance, with personalization inputs that allow team members to quickly and easily personalize specific parts of the video to their audience.
Video templates are the backbone of efficient video creation in 2026. They give teams a clear, repeatable structure for telling stories, explaining products, or breaking down concepts without requiring a designer, editor, or a fresh production cycle for every new asset.
Why video templates matter in 2026
Explainer videos often follow the same narrative pattern: setup, problem, solution, next step. This makes templates a natural fit. They ensure every video is:
- Fast to produce
- On-brand and compliant
- Customizable and shareable in minutes
- Replicable across teams, products, and campaigns
This repeatability is what organizations need as video volumes increase across marketing, sales, and customer experience functions.
Video templates as a powerful enabler for sales, marketing & CX
For customer-facing teams, video templates are especially valuable because they remove friction. Sales reps, CSMs, and CX leaders aren’t able to storyboard a new video every time a prospect asks a question or a customer needs clarity—they need something structured and ready to personalize; without it, they don’t have video as part of their strategy.
Behind that friction are four very real challenges that most revenue and CX teams run into when trying to use video consistently:
- It’s too hard to create. Reps rarely have the time—or the creative skill set—to produce polished videos from scratch.
- It’s too slow to adopt. If a tool feels clunky, teams simply won’t use it.
- It’s too off-brand. When everyone creates videos differently, quality and consistency start to slip.
- It’s too generic. One-size-fits-all videos don’t resonate with modern buyers or customers.
Video templates directly address these challenges by giving teams a repeatable, on-brand starting point for any explainer. Instead of reinventing the wheel, reps and CX leaders can pull from a foundation that’s already been built for them. With the right template workflow, they can:
- Easily create pro-level videos without needing creative expertise
- Adopt quickly, because templates slot naturally into existing workflows
- Stay on-brand, thanks to guardrails around visuals, messaging, and structure
- Truly customize videos with specifics relevant to a deal, customer, or situation
This balance of speed, consistency, and personalization is what makes video templates such a powerful tool for explainers, especially in high-volume environments.
SundaySky’s Amplify solution is one example of how enterprises are operationalizing video templates, giving revenue and CX teams access to ready-to-go, on-brand explainer videos pre-built by team leaders that they can customize quickly while still following brand guidelines. It’s not about flashy promotion, but about making video creation part of everyday workflows without slowing teams down.
Must-have #3: AI voices
A clear, well-paced voiceover is the backbone of every strong explainer video. AI voices have advanced significantly by 2026, allowing teams to achieve studio-level narration without hiring voice actors.
Why AI voices matter
AI voices offer:
- Natural, human-like tone
- Instant script updates
- Multilingual support
- Emotion, pacing, and emphasis for clarity
- Consistent delivery across dozens—or thousands—of videos
Pairing AI voices with a script template streamlines creation even more. With AI narration, you can revise messaging on the fly, which is ideal for product changes, regulatory updates, or evolving employee training.
The strategic power of Custom AI Voices
While standard AI voices are incredibly useful for speed and scale, Custom AI Voices have emerged as the preferred choice for explainer videos in 2026, especially across sales, marketing, CX, and product education.
A Custom AI Voice lets teams create a fully cloned, lifelike version of a real person’s voice, whether that’s a manager, a product expert, a CX leader, or an executive who regularly communicates with customers.
Because explainer videos rely on clarity and trust, using a familiar, authoritative voice can dramatically improve comprehension and engagement. Custom AI Voices enable teams to:
- Bring a recognizable company voice to every video, without requiring someone to record voiceovers
- Maintain continuity across product explainers, onboarding content, policy updates, or follow-ups
- Update scripts instantly using the same trusted voice—critical for regulated or high-velocity environments
- Localize content while retaining speaker identity, using the cloned voice across multiple languages
- Achieve a more human, connected feel that’s hard to replicate with generic or stock AI narration
For example, a CX director can “narrate” every onboarding and support video without stepping into a recording booth. A sales leader can deliver every prospecting, demo recap, or proposal walkthrough message with a consistent tone and clarity. And a product manager can guide users through every new release, even while traveling or offline.
Custom AI Voices turn explainer videos into something more personal, credible, and scalable, delivered in a voice your audience already knows and trusts.
Make an explainer video: Step-by-step
A modern 2026 explainer workflow looks like this:
1. Select or create a Custom Avatar
Pick a brand-appropriate persona to deliver the message.
2. Make an explainer video template

This entire process can take under 10 minutes while staying on brand, consistent, and scalable across teams.
Choosing the best explainer video maker
With dozens of AI video tools available, organizations often face a choice: use a point solution that focuses on one part of the workflow, or adopt a more holistic creation and governance platform.
The right 2026 explainer video maker should:
- Offer video templates, avatars, and AI voices in one place
- Support brand control and governance
- Enable team-wide collaboration
- Handle multilingual and global content
- Scale across marketing, sales, CX, and L&D teams
- Simplify work, not complicate it
