Here at CSW, we’ve been using AI tools right from the start — including in our own SEO, SEA and social media operations. Yes, feel free to take that as a bit of self-praise. But it does make us reasonably reliable judges when it comes to practical applicability.
Five tools that really deliver — for voice-overs, video generation, AI avatars, music and interactive formats. This isn’t meant to be an exhaustive list, but an honest overview. And that’s exactly what we’ll be looking at below.
1) ElevenLabs: Voices that are almost indistinguishable from the real thing
ElevenLabs has established itself as one of the most widely used platforms for AI speech synthesis. With a range of languages, adjustable emotions and natural-sounding voices, the results sound better than many expect after watching the first demo videos.
According to TechCrunch, ElevenLabs achieved US$330 million in Annual Recurring Revenue (ARR) in 2025 — the latest growth spurt from 200 to 330 million took just five months. That’s a staggering figure which shows that the market is taking the tool seriously.
Ideal for: professional voice-overs, e-learning content, advertising and audiobooks — without having to hire a studio or coordinate schedules with external voice-over artists.
If you want to reduce voice-over costs without compromising on quality, you’ve come to the right place.
2) Runway: Text in, video out
Text-to-video sounds like something straight out of a sci-fi film. Runway has turned it into a practical tool. You describe what you want to see in the video in a text prompt — and the AI creates it.
Spoiler: Pixel-perfect production videos still require manual finishing touches. However, for concept visualisations, storyboards and creative exploration, Runway’s approach is already practical — and the transition from Gen-2 to Gen-3 shows just how quickly the sector is advancing.
Ideal for: content creators, marketers and anyone who wants to visualise ideas quickly without a production budget.
3) Synthesia: Avatars in 120 languages
Synthesia replaces cameras, actors and sound studios with AI-generated avatars. Upload a script, choose an avatar, export a video — it sounds simple because it actually is.
TechCrunch reports that Synthesia now has more than 60,000 business customers — including half of the Fortune 100 companies. This shows just how seriously the market is taking this technology.
Particularly effective: training videos, internal onboarding and explanatory content. For teams that produce this sort of content regularly, the value for money pays off quickly.
4) Boomy: Music at the touch of a button
Music production isn’t a core focus for most content teams. Boomy offers a practical solution: choose a genre, adjust the parameters, and the AI generates the song.
This isn’t a replacement for musicians — that would be unfair to both parties. But it’s a solid solution for background music in videos, presentations or podcasts. No GEMA debates, no licence fees. Anyone who’s ever worked out how much licensed music costs over the course of a year will appreciate this.
Ideal for: anyone who regularly needs background music for their content — fast, practical and budget-friendly.
5) D-ID: Avatars that react
D-ID goes a step further than mere video generation. The AI avatars are interactive — they respond to input and questions, making them ideal for dialogue-based training formats and virtual assistants.
Multilingual support makes D-ID relevant for international teams too. Anyone looking to combine marketing automation with personalised avatar formats will find a practical starting point here.
Ideally suited for: interactive e-learning formats, customer communication and Q&A-style presentations.
So, what next?
AI hasn’t replaced content production — but it has significantly lowered the barriers to entry. Voice-overs without a studio, videos without a camera, music without formal training. This isn’t just hype anymore. It’s a toolkit.
Anyone who also wants to keep an eye on visibility in AI-powered search systems should look into Generative AI Optimisation (GAIO) — this topic is becoming increasingly relevant for content teams.

FAQs on AI tools for content production
What are AI content tools and how are they used?
AI content tools are software platforms that automate tasks such as speech synthesis, video generation, avatar creation and music production. They are used to speed up content production and reduce costs — without having to rely on external service providers.
Can I try ElevenLabs for free?
Yes. ElevenLabs offers a free basic version with limited features. Paid plans are required for professional use with higher character limits and more voice options.
Who would benefit from Synthesia?
Synthesia is particularly worthwhile for teams that regularly produce training videos, onboarding content or explainer videos. For one-off projects, it’s worth taking a closer look at the value for money.
Just how good are AI-generated videos from Runway really?
The quality is already impressive for concept visualisations and creative exploration. For highly consistent production videos, post-production is still required. Runway is recommended as a tool for generating ideas and accelerating the creative process — not as a complete replacement for traditional video production.
Are AI-generated voices and avatars legally safe to use?
This depends on the platform and intended use. Each platform has its own licence terms, which must be checked before commercial use. Particular care is required when using voice cloning functions for real people.
