Zapier defined the category. It connects 9,000+ apps, has millions of users, and lets anyone build a "Zap" in minutes with a point-and-click editor. If all you need is "when X happens in App A, do Y in App B," Zapier handles it with near-zero learning curve.
The gap shows up when the work between those apps requires judgment. Summarizing a support ticket before routing it. Enriching a lead with web research before deciding which rep gets it. Writing a personalized follow-up email based on meeting notes. Those tasks need an LLM at the core of the workflow, not bolted on as one step in a chain. And when your team needs to know what each run actually costs, or deploy the whole thing on your own infrastructure, Zapier doesn't have an answer.

When to use Zapier
Zapier is hard to beat for simple, high-volume app-to-app automation. Its 9,000+ catalog means you'll rarely hit a gap, and the editor is approachable enough for anyone. If your workflows are mostly "move this data there" without AI reasoning, and you don't need cost visibility or self-hosting, Zapier is the safe default.
When to use General Input
General Input is for teams where the automation itself needs to think, not just shuttle data.
- AI at the core, not the edge. Your workflows require reasoning: reading documents, making decisions, generating content. General Input treats the LLM as the engine, not a plugin.
- Three workflow types in one platform. Connect apps, write deterministic scripts, or deploy autonomous agents. All three share the same dashboard, permissions, and monitoring. Zapier separates Zaps and Agents into different products with different billing.
- Model agnostic. Zapier limits you to the models they surface. General Input runs on OpenAI, Anthropic, open-source, or your own fine-tuned models. Switch providers without rebuilding.
- Security and compliance. Credentials are encrypted and never exposed to the AI model context. Deploy on-prem for regulated industries, air-gapped environments, or data sovereignty requirements. Zapier is cloud-only.
- Cost transparency. Zapier bills per "task" but the effective cost per run depends on your plan tier and how many steps you use. General Input shows the exact dollar cost of every execution, broken down by step.
Better together
Use Zapier for the long tail of simple app-to-app triggers it handles well, and General Input for the AI-native workflows that need reasoning, cost control, and enterprise security.
