AI-generated social videos from scripts and clips
Spira Maxima is an AI social-video production tool that turns scripts, topics, product photos, presenter inputs or existing recordings into finished vertical videos. It is designed for TikTok, Reels and Shorts workflows where the goal is to create a complete post rather than generate isolated video clips.
The system combines presentation, motion graphics, B-roll, typography, captions and music in one generation. Users can start with a script, ask Spira to draft one from a topic, add their own photo and voice, or upload a recording for the system to build around. The result includes a 9:16 MP4 plus a caption and hashtags, reducing the amount of manual assembly needed before publishing.
Key features
Presenter and visual composition
The output can combine a matched or user-provided presenter with supporting B-roll, motion graphics, typography and styled captions.
Optional face and voice customization
Add a clear photo to create an AI avatar, or supply a voice sample so the generated presenter can use a voice associated with you.
Integrated audio
Music is composed into the finished post, with the generation interface also exposing sound-effects and voice controls.
Social-oriented styling
The model is described as post-trained on social trend and performance data, using those signals to shape the visual treatment for social feeds.
Ready-to-post output
The workflow produces vertical 9:16 MP4 videos and provides a caption and hashtags to post with them. The interface shows 1080p as an output option.
Use cases
Product promotion
Turn product photos and a short product script into a promotional post with music, captions and motion, giving a product team a repeatable launch or collection workflow.
Service marketing and explainers
Convert expertise, tips or service explanations into short educational posts with a presenter, supporting B-roll and feed-oriented captions.
Founder-led content
Create founder pitches, announcements and behind-the-scenes messages using a personal photo, voice sample or an uploaded recording when maintaining a recognizable delivery matters.
Creator publishing
Give creators a way to publish more frequently by starting from their own script or clip while Spira handles the supporting visuals, typography and audio.
High-volume social production
Help marketing teams produce recurring vertical posts from a shared set of scripts and product assets without manually assembling every element of each video.
Pros and Cons
Pros
- Generates a composed social post with motion graphics, B-roll, captions and music rather than returning only raw footage.
- Accepts several starting points, including scripts, topics, product photos, personal presenter inputs and existing recordings.
- Supports optional customization with a user photo and voice sample, while also allowing a matched presenter when no presenter is supplied.
- Provides vertical MP4 output with accompanying caption and hashtags for a social posting workflow.
- Can produce videos up to 90 seconds on the documented Growth tier, which is longer than the shorter clip limits described for some scene-generation workflows.
Cons
- The documented workflow is optimized for vertical social video, so it may not fit projects that require other aspect ratios or conventional long-form editing.
- Plan limits vary by tier, including maximum video duration and script length; advanced editing and additional integrations are not documented on the Maxima page.
- The product-specific evidence does not establish a full list of publishing destinations or collaborative team controls.
FAQ
What can I use as input?
You can begin with a spoken script, a script plus your photo, a script plus product photos, or a recording you already have. The interface also supports asking Spira to draft a script from a topic, and you can optionally add a voice sample or upload a speaker clip.
Can I use my own face and voice?
Yes. Add one clear photo to create an AI avatar and provide a voice sample if you want the result to sound like you. Alternatively, start with a recording; your footage and delivery remain while Spira adds motion graphics, B-roll, captions and music around them.
What does the generated video include?
Spira Maxima returns a finished vertical 9:16 MP4 with a caption and hashtags to accompany the post. The product page describes outputs containing a presenter, motion graphics, B-roll, typography, styled captions and music.
How long can the videos be?
The documented maximum depends on the plan: Free supports up to 20 seconds and a 400-character script, Creator supports up to 60 seconds and 1,200 characters, and Growth supports up to 90 seconds and 1,800 characters.
Who is Spira Maxima designed for?
Spira Maxima is intended for brands, service businesses, founders, marketing teams and creators who want to produce social posts without editing every detail. The broader Spira pricing page also lists social generation and publishing features, but the Maxima page does not document a complete product-specific publishing integration list.
