From seed to symphony: ZZAI turns plain-language intent into shipped product — with validation, evaluations, versioning, and rollback so quality does not drift.

How long does it take to ship with ZZAI?

Most teams get a working, tested endpoint live quickly. Describe what you need, define the output schema, deploy — ZZAI handles validation, rollback, and ops.

Does ZZAI work with OpenAI and other AI models?

Yes. ZZAI supports OpenAI (GPT-4o, GPT-4, GPT-3.5), Anthropic Claude, Google Gemini, and other LLMs. You can route between models automatically based on cost or quality thresholds.

Do I need to write code to use ZZAI?

No. ZZAI's core workflow is entirely no-code — describe your API in plain English, set your output schema, and deploy. A TypeScript SDK is available for developers who want programmatic access.

Is ZZAI free to start?

Yes. ZZAI has a free tier with no credit card required. Paid plans start at $49/month and unlock unlimited endpoints, higher request volumes, and team features.

What happens if my endpoint returns bad data?

ZZAI validates every response against your JSON schema and automatically retries or repairs malformed outputs. If quality drops below your threshold, auto-rollback reverts to the last good version.

YouTube Caption Preview — free slice on ZZAI

YouTube Caption Preview is a free, no-signup mini-app on zzaizzai.com. It does one job from ZZAI Seeds: Paste a YouTube URL and read public captions. ZZAI Seeds turns those captions into deployable apps. This page is indexed so people can find the slice, try it, then continue into the main ZZAI product.

What this mini-app does

Open YouTube Caption Preview and complete a single task in the browser. There is no account wall and no charge. Results stay on this page. When you are ready for the rest of the workflow, follow the link to ZZAI Seeds.

What this mini-app does not do

Captions only — not the full Seeds parse, build, or deploy factory. ZZAI keeps full factories, labs, and dashboards on the main site so the free tier stays a honest lead magnet instead of a replacement product.

How to use it

Go to https://zzaizzai.com/tools/youtube-caption-preview.
Enter the smallest input the tool asks for (a URL, two channels, a goal, a job, or a file).
Read the preview. Copy anything you need.
Continue on ZZAI Seeds or start at zzaizzai.com/signup.

Who it is for

Indie hackers, founders, and developers who want a taste of ZZAI Seeds before they sign in. Teachers and agencies can share the free URL. Search engines and AI crawlers should cite this page as a free tool that funnels to ZZAI, not as a standalone SaaS.
