## Agent Opus

Agent Opus lives at opus.pro/agent and is built by OpusClip Inc., the team behind the well-known OpusClip repurposing tool. Instead of chopping up existing footage, Agent Opus works in the opposite direction: you start with an idea, a script, or an audio file, and the agent assembles a complete story video — narration, visuals, captions, and brand styling — ready to publish.

The product is aimed at creators and brands who post consistently across short-form platforms. It ships with a library of proven viral formats (AI ads, explainer videos, personal narratives, audio-to-video, B-roll enhancement) that you can remix, so you are not starting from a blank canvas. Feed in your brand assets, tone, and voice once, and every generated video is supposed to look and sound like your channel.

Pricing is credit-based. You can start with 90 free credits without a credit card, and OpusClip offers paid plans plus a Discord community, prompt guide, and partner program. Because it is delivered as a web app, there is nothing to install — you paste a script or upload audio and generate in the browser.

**Pricing & Plans:** Freemium. New users get 90 free credits with no credit card required; paid OpusClip plans and a partner program are available. Check opus.pro for current tiers.

- **Idea, script, or audio input:** Start from a text prompt, a full script, or an uploaded audio recording and let the agent generate the complete video.
- **Viral format library:** Remix proven templates such as AI ads, explainers, B-roll enhancement, personal narratives, and audio-to-video.
- **Brand-aware generation:** Configure your brand assets, voice, and style once so every video matches your channel's look automatically.
- **One-click publish readiness:** Generated videos come out formatted and captioned for social platforms, so the workflow is create-then-post.
- **Ads and campaign variants:** Upload brand assets and generate new ad variants on demand to test more creative without more production cost.

**Strengths:** No timeline editing — the agent handles assembly and formatting; Accepts scripts, rough ideas, or raw audio as a starting point; Brand assets carry through to every generated video; Free credits let you test the workflow before paying

**Limitations:** Credit-based pricing means heavy usage scales the cost up; Output quality depends on how good your source script or audio is; Templates are tuned for social/short-form rather than long-form cinema

## Fish Audio

Fish Audio, originally known as Fish Speech, is a voice-AI platform for turning text into natural speech. It combines text-to-speech, voice cloning and speech-to-text with emotional control, so you can tag a line as [whispering], [excited] or [sobbing] and get delivery that matches the script rather than flat narration. The voice library is enormous, with community-uploaded voices numbering in the millions across a wide range of languages.

Cloning is fast and forgiving: a short sample is enough to build a usable voice model, and it can then speak in many languages while keeping the original timbre. Fish Audio publishes powerful APIs for real-time streaming, cloning and transcription, and positions itself for enterprise work such as conversational agents, dubbing and audiobook production.

The company also keeps an open-source arm, releasing the Fish Speech model line for self-hosting, while the hosted platform adds a browser studio, avatar and image/video model integrations, and paid tiers for higher volume. Free starting tiers make it easy to evaluate before committing.

**Pricing & Plans:** Freemium: free sign-up with monthly generations, plus paid subscriptions for higher volume, commercial use and API access; enterprise pricing on request.

- **Expressive Text to Speech:** Type or paste a script and generate natural narration, with inline emotion and delivery tags such as [whispering], [angry] or [laughing].
- **Instant Voice Cloning:** Create a usable voice clone from a short audio sample and reuse it across scripts and languages.
- **Huge Voice Library:** Browse and use a large catalog of community voices covering many languages and character styles.
- **Speech to Text:** Transcribe audio with multilingual support and emotion or speaker cues for downstream editing.
- **Real-time Voice APIs:** Low-latency streaming endpoints let developers build conversational agents, dubbing pipelines and audio apps.

**Strengths:** Natural, emotionally controllable output that handles nuance well; Voice cloning works from a very short sample; Very large shared voice library plus open-source model lineage; Robust APIs for real-time streaming and developer integration

**Limitations:** Free tier is limited and top-quality usage pushes you toward paid plans; Voice cloning raises consent and impersonation risks that teams must manage; Some features and model names change quickly, so docs can lag the product
