Generate, refine & manage
media through one endpoint

Composable media generation for AI agents — with a cloud library to manage what they create, an editing engine to refine it, and analysis tools to close the quality loop.

Agents build through MCP. Humans review in the web workspace. Teams collaborate with shared projects. x402 users authenticate with just a wallet.

Iterative Agentic Design

Agents that critique their own work

analyze_media with Gemini vision QA lets agents evaluate their output against an intent checklist, then decide whether to re-generate, edit in post, or approve.

1
Generate
Agent creates image, video, or audio from a prompt
2
Analyze
analyze_media evaluates quality, checks intent, scores output
3
Decide
Agent compares result against spec — pass or iterate?
4
Refine
Re-generate with adjusted prompt, or edit_video to fix in post
5
Store
Approved asset saved to library with lineage and tags
analyze_media(resource_id, analysis_type="vision_qa", intent_checklist={"no_pillarboxing": true})
Spec-driven QA: each checklist item becomes an explicit pass/fail check

Collaborative by Design

Three ways in. One shared workspace.

Agents connect via MCP. Humans work in the web UI with the Crew chatbot. x402 users authenticate with a crypto wallet — no account needed. All three share the same projects, assets, and permissions.

Editing Engine

Post-production in the pipeline

Agents don't just generate — they edit, composite, and deliver finished media. Humans can step in via the web UI to fine-tune anything the agent produced.

Cloud Resource Management

A persistent library agents can build on

Other platforms return a URL that expires. Soundside gives agents — and the humans who work with them — a persistent cloud library with projects, collections, brand kits, and full derivation history.

📁
Projects & Collections
Organize assets into projects with nested collections. Filter by type — images, video, audio, text, documents. Every resource gets a persistent cloud URL.
🎨
Brand Kits
Define colors, fonts, logos once. Every artifact — decks, docs, diagrams — inherits brand identity. Consistent output without repeating style instructions.
🧬
Lineage Tracking
Every resource knows its parents. Trace a final video back through its narration, music, key frames, and original character references. Full provenance chain.
🔎
Search, Tags & Metadata
Full-text search across names, tags, prompts, and provider metadata. Tag resources during generation. Filter across projects.
