## 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

## Giststack

Giststack targets the specific gap between consuming good material and actually publishing a point of view about it. Instead of leaving your best ideas as bookmarked links, the tool organises everything you follow — newsletters, websites, blogs, YouTube channels and podcasts — into one reader, then scores and ranks the individual takeaways ('insights') inside each item and the larger themes ('stories') that recur across several publications.

From there you pick a takeaway that is worth discussing, add your own perspective from client or industry experience, and let Giststack produce a first draft. A saved writing persona controls the voice, while the editable Brand Profile tells the system who you serve and which themes you want to be known for, so relevant stories get prioritised for you. Output formats include social posts, video scripts, newsletter drafts and longer custom long-form pieces.

The platform also includes a private knowledge base where you can upload your own PDFs, Word files and notes, mine them for insights, and recycle work you have already done into new drafts. Direct publishing to networks like LinkedIn, X, Facebook, Instagram and Threads is offered through the optional LarkPulse add-on, which also handles scheduling, queuing, first comments and version adaptation. Webhooks for pushing drafts to other tools are available on the Pro tier and above.

**Pricing & Plans:** Giststack is a paid product with subscription tiers chosen from the site's pricing page; the free trial entry point is available via 'Choose your plan'. Publishing to social networks requires the separate LarkPulse add-on, while webhook integrations start on the Pro plan. Check the official pricing page for current numbers.

- **Unified reader:** Bring newsletters, blogs, websites and YouTube channels into one feed, skim summaries and keep your sources organised in one place.
- **Insights and Stories:** AI scores takeaways inside a single article, video or newsletter (Insights) and detects wider themes that span several publications (Stories).
- **Persona-driven drafting:** A saved writing persona and an editable Brand Profile steer the tone of the draft and prioritise stories that match the themes you want to be known for.
- **Private knowledge base:** Upload your own PDFs, DOCX files and notes, mine them for insights, and convert existing reports or frameworks into new content.
- **LarkPulse publishing add-on:** Adapt one idea per network, publish, schedule or queue posts, and add first comments automatically across LinkedIn, X, Facebook, Instagram and Threads.

**Strengths:** Turns passive reading into a repeatable draft pipeline instead of an empty editor; Insight scoring and cross-publication 'Stories' help you find a discussable angle quickly; Brand Profile and persona keep drafts on-voice without rebuilding context every time; Private knowledge base lets you reuse your own reports and frameworks as source material

**Limitations:** Social publishing is not included and needs the paid LarkPulse add-on; Output is deliberately a first draft — your own experience still has to be added to make it publishable; The reader-centric workflow takes some setup before it pays off
