Makko AI is an end-to-end AI game studio for 2D games. Describe your concept and it generates characters, backgrounds, and animations that stay visually consistent through its 'Collections' system — set the art style once, every asset inherits it. Then use Code Studio to assemble those assets into a playable game, still without writing code. Launched April 20 on Product Hunt with a free tier.

Act-Three generates lifelike character animation — including nuanced facial expressions, lip sync, and upper-body motion — from a reference image and an audio or text prompt. It requires no rigging, no motion capture setup, and no 3D modeling expertise. Feed it a still image and audio, and it outputs a video of that character speaking and moving expressively.
Reviewer scorecard
“The Collections consistency system is the real innovation here — every other AI art tool gives you one-off images that don't look like they belong together. For game jam prototyping or solo indie dev, this compresses weeks of art work into hours. Genuinely useful.”
“The output style range is limited and professional studios won't touch it — the assets look obviously AI-generated. 'No coding required' games will also hit a complexity ceiling fast. It's a toy for prototyping, not a real game development pipeline.”
“Direct competitors are HeyGen and D-ID, both of which have been doing audio-driven avatar animation for two years — so the category isn't new. What Act-Three actually does differently is animate non-avatar characters: illustrated figures, stylized portraits, fictional characters from concept art, not just photorealistic headshots. That's the real differentiator and Runway should be saying it louder. The scenario where this breaks is any character with an unusual face structure — highly stylized art with asymmetric features, animals, or side-profile images all produce artifacts that break the illusion immediately. What kills this in 12 months: HeyGen ships stylized character support and undercuts on price, because Runway's model costs scale faster than their subscription tiers suggest. What would have to be true for me to be wrong: Runway has quietly built proprietary training data on non-photorealistic characters that HeyGen can't replicate cheaply.”
“The game development market is about to be flooded with content from people who previously had zero path to shipping. Tools like Makko collapse the skill floor so dramatically that the question shifts from 'can I make a game' to 'what game should I make.' That's a cultural shift.”
“The thesis Act-Three bets on: within three years, the cost of character animation drops below the cost of casting voice actors, which collapses the economic barrier for indie game cutscenes, educational simulations, and localized marketing. The dependency that has to hold is that generated motion stays legally distinct from the reference image subject — if a court rules that animating a real person's photo requires their consent for every output frame, this use case evaporates for commercial work. The second-order effect that matters: this doesn't just speed up animation, it shifts creative power to writers and concept artists who've never had access to motion tools. The scenario where this is infrastructure: a game studio uses Act-Three to generate all NPC dialogue animations in 48 hours instead of a 6-week mocap pipeline. Runway is early on the non-photorealistic animation trend line, and early is where the moat gets built.”
“As someone who's spent hours fighting style inconsistency in AI art, the Collections system is genuinely elegant. You describe your world once, and everything generated after that respects it. The pipeline from concept to playable prototype is smoother than anything I've tried before.”
“The output is genuinely uncanny in the right direction — mouth shapes follow phonemes rather than averaging them into a blur, and eye movement has micro-saccades that make the face feel inhabited rather than puppeted. The taste layer is baked in: Runway has made strong decisions about what 'natural' looks like and the defaults hold up. The editing surface is shallow though — you get one pass at timing and expression intensity, and if the audio-driven movement doesn't feel right, your recourse is re-prompting rather than keyframing. The fingerprint is there if you know what to look for (a certain smoothness in head movement transitions), but it's subtle enough that most audiences won't clock it. The craft decision that earns the ship: they prioritized believability in the upper face over perfect lip sync, which is the right call — humans read emotion from eyes first.”
“The buyer here is a content creator or small studio who pays out of the Runway subscription they already have — Act-Three is a feature, not a product, which means Runway captures the value through subscription retention rather than direct pricing. That's fine for Runway as a company, but it means Act-Three lives or dies by whether it drives Runway plan upgrades, and I'm skeptical it does at the current quality tier for professional buyers. The moat question is brutal: HeyGen has a head start in the enterprise avatar market, Kling and Hailuo are compressing the consumer market from below, and Act-Three is wedged in the middle with no obvious distribution advantage. What would need to change: Act-Three needs to either go upmarket into a dedicated API product with per-second pricing that studios can actually budget for, or become the clear quality leader with a public benchmark. Right now it's neither.”
