Common questions about workflows

What does a workflow do?

A workflow is a chain of automated steps that run on their own. The outcome depends on what you build — for example a daily email summary, auto-sorted files, or AI-generated reports.

How do I create a workflow?

Go to Home, click "+ New" on the top right. Choose Workflow to start with a template, or start from scratch. Then use "Build with AI" chat to describe what you want in plain English.

What are the steps in a workflow?

Each workflow is a chain of nodes: triggers, AI agents, tool actions, and code blocks. You connect them in sequence to automate tasks end to end.

Can it connect to my tools?

Yes. Needle supports >40 connectors including Gmail, Slack, Google Drive, Notion, and many more. In the video above you can see Gmail being connected mid-build.

What does "Build with AI" do?

It's an AI agent inside the workflow builder. Describe what you want and it generates the nodes, connects your tools, tests the workflow, and self-fixes errors — all automatically.

How do I observe workflow runs?

Every workflow has a Runs tab that logs each execution. You can see exactly which node failed, inspect its inputs and outputs, and fix the issue. Version history lets you roll back anytime. In each node you can observe Input and Output, which can point to specific issues as well.

Common questions about collections

PDF, DOCX, TXT, CSV, JSON, HTML, Markdown, XLSX, PPTX, PNG, and JPG. Pro plans also support image and table extraction from PDFs.

Which data sources can I connect?

Gmail, Google Drive, Slack, Notion, GitHub, Confluence, Jira, Outlook, OneDrive, SharePoint, Dropbox, Airtable, Zendesk, HubSpot, and more. Connected sources auto-sync so your data stays current.

How does the AI search work?

Needle splits your documents into chunks, generates vector embeddings, and stores them in a database. When you ask a question, it performs a semantic search to find the most relevant chunks and uses an AI model to generate a grounded answer with source references.

Is there a file upload limit?

Free plans have a file upload limit. Pro plans scale to thousands of documents per collection.

Can I embed the chat on my website?

Yes. Every collection can be shared via a public link or embedded as a chat widget on any website with a simple code snippet. You can also use collections inside workflows for automated RAG pipelines.

How do I manage access?

Collections support role-based permissions at the workspace, project, and collection level. You can invite teammates as owners, editors, or viewers, and revoke access at any time.
