CorpusIQ vs n8n
n8n is an open-source workflow automation platform, self-hostable and extensible through 400+ community nodes. CorpusIQ is a managed AI reasoning layer that exposes 22+ business tools to ChatGPT, Claude, and Perplexity through the Model Context Protocol. One is for building custom automation; the other is for answering cross-source business questions in plain English. CorpusIQ starts at $29.95 per month. n8n has a free self-hosted community edition and a paid cloud tier.
Feature comparison
| Feature | CorpusIQ | n8n |
|---|---|---|
| Purpose | Answer cross-source business questions in ChatGPT, Claude, or Perplexity using live data from connected tools. | Build and run workflow automations that trigger nodes on schedules, webhooks, or events. |
| Primary users | Business owners and operators who want cited answers without engineering effort. | Developers and technical ops teams building custom automation, often self-hosted. |
| Model Context Protocol native | Yes. Every connector exposes MCP tools to ChatGPT, Claude, and Perplexity. | n8n has community MCP nodes but is not MCP-native. The core model is workflow-node execution. |
| Hosting model | Managed cloud on Microsoft Azure. No self-host option. | Self-hostable on your own infrastructure, or available as n8n Cloud. |
| Connector count | 22+ live connectors focused on SMB business tools. | 400+ community-maintained nodes, strong custom HTTP and code-execution primitives. |
| Cross-source intelligence | Built-in: one prompt hits every connector in parallel and returns a single cited answer. | Possible via a workflow that fans out to multiple nodes and merges results, but the user designs it. |
| OAuth scope model | Read-only scopes only. CorpusIQ cannot write back or modify data in any connector. | Full read and write, because workflows commonly create records, send messages, or trigger downstream actions. |
| Code requirements | Zero code. Setup is OAuth and a prompt. | Visual nodes for most integrations, but non-trivial workflows often involve JavaScript expressions. |
| Data retention | Zero data stored. Queries are ephemeral. | Execution history and payloads are persisted for retry and debugging. |
| Pricing entry point | $29.95 per month for Solo, all connectors included, 30-day free trial. | Self-hosted community edition is free. n8n Cloud starts at $20 per month. |
| SMB fit | High. Owners and small operators who want live cross-source reasoning with zero ops. | Medium. Requires technical comfort; strong fit when you need fully custom automation or self-hosting. |
When to pick n8n
n8n is the right answer when you need open-source workflow automation you can host yourself, or when the job requires custom code, HTTP integrations beyond a curated connector set, or write-back to downstream systems. The community-node marketplace is deep and the product is well-documented.
n8n is also the right answer when compliance or cost pressure requires the automation engine to run on your own infrastructure. The community edition is free, and the architecture scales horizontally.
When to pick CorpusIQ
CorpusIQ is the right answer when the job is cross-source reasoning, not automation. Ask ChatGPT to compare Shopify revenue to Google Ads spend and QuickBooks expenses. Summarize the last 30 days of Gmail threads about a specific customer. Reconcile HubSpot deals against paid invoices, in a single prompt, with source citations on every fact.
CorpusIQ is also the right answer when the use case calls for a strictly read-only posture on OAuth scopes and zero data retention. CASA Tier 2 certified by DEKRA, hosted on Microsoft Azure, no self-host burden.
Using both together
n8n and CorpusIQ do not conflict. A common pattern is n8n for the ETL and webhook plumbing and CorpusIQ for the analytics interface on top. n8n moves data where it needs to go; CorpusIQ explains what the data means through ChatGPT. Separate OAuth grants, separate concerns, no overlap.
Frequently asked questions
No. CorpusIQ is a managed service hosted on Microsoft Azure. The product is priced for small and mid-size businesses ($29.95 per month on Solo) and does not require self-hosting. n8n remains the right choice when open-source licensing or self-hosting is a hard requirement.
Partially. You can build an n8n workflow that queries multiple APIs and merges the results, but you design it yourself and maintain the nodes. CorpusIQ is MCP-native, so ChatGPT, Claude, and Perplexity query every connected tool in parallel automatically in response to a plain-English question. No workflow to build, no nodes to maintain.
Not today. CorpusIQ is a curated set of connectors with read-only scopes and MCP tool wrapping. If you need to hit an arbitrary HTTP endpoint or run custom JavaScript inside a workflow, n8n is the right tool. You can combine the two: n8n handles custom automation, CorpusIQ handles cross-source reasoning.
Both models are defensible. CorpusIQ's answer is a small attack surface: read-only scopes, zero data retention, CASA Tier 2 certified by DEKRA, hosted on Microsoft Azure. Self-hosted n8n gives you full infrastructure control, which is attractive if your compliance requires data to stay on your own network. n8n Cloud falls in between.
Yes. The two products share no OAuth grants and do not compete for the same job. A common pattern: n8n handles scheduled syncs and write-heavy automation; CorpusIQ handles the interactive analytics layer on top through ChatGPT or Claude.
