F.A.Q.
What is Flyder Harness?
Harness is a visual builder for AI workflows. You connect AI steps, conditions, loops, API calls and emails on a canvas, then run the workflow right away, in the background or on a schedule.
Do I need to know how to code to use Harness?
No. You build workflows by dragging steps onto a canvas and connecting them. Developers can go further with the API and by connecting their own tools.
What can I automate with Harness?
Anything that follows repeatable steps: summarizing documents, classifying images, researching a topic on the web, drafting and sending emails, or producing a regular report and emailing it to your team.
Which AI models does Harness support?
You can choose models from OpenAI, Anthropic and Groq, and pick a different model for each task depending on the speed, cost and quality it needs.
Can Harness search my own documents with AI?
Yes, in two ways. RAG search turns PDFs, Word files, Markdown or text into a knowledge collection your AI tasks can search for the most relevant passages. PageIndex maps long documents by their sections and pages so the AI can read through them like a person would. Workflows can add new documents as they run.
What is the difference between RAG and PageIndex?
RAG is best for searching a large collection of documents quickly for the passages that match a question. PageIndex is best for long, structured documents such as manuals, contracts and reports, where the AI needs to follow the table of contents and read the right pages to get the answer right. It only states what those pages say, and one task can search several documents.
How do I run a workflow?
Run it and wait for the result, send it to a background queue, or schedule it. Queued work has its own page so you can see what is running.
Can workflows run on a schedule?
Yes. Schedule a workflow for a specific date and time, or set it to repeat automatically so reports and routine jobs run without anyone starting them.
Can a workflow make decisions or repeat steps?
Yes. Branching steps send a workflow down different paths based on the result, and loop steps repeat work for every item in a list or until a result meets your standard. Loops have built-in limits so they always finish.
Can Harness work with email?
Yes. AI tasks can search, label and send Gmail messages, and a Send Email step can deliver a workflow’s result to anyone you choose.
Can Harness search the web?
Yes. An AI task can use live web search to pull in current information before it answers.
Can Harness connect to my other systems?
Yes. An API step can call any web service, and the MCP Gateway links Harness to tools and data on your own machines through the Model Context Protocol.
Can Harness work with files and images?
Yes. A workflow can start from a file instead of text, including images the AI can read and classify, and a task can carry fixed reference files it always compares against.
How do I see what a workflow did?
Every run records which steps ran, in what order, how long each took and what went in and out of it, so you can find exactly where a result went wrong.
Can I build a chatbot with Harness?
Yes. An AI task can sit behind a chat that remembers the conversation, and every chat people have with it is saved in the task’s history.
Does Harness have an API?
Yes. With a personal API key you can list and run workflows, manage knowledge collections and chat with your tasks from your own apps.
Is my data private in Harness?
Your workflows, tasks, documents and API keys belong to your own account and are not shared with other users.
How is Harness different from Flyder Engage?
Engage is a chat assistant for your website visitors. Harness is for automating your own team’s work behind the scenes. Many teams use both.
How much does Harness cost?
Harness is currently free to use. You can sign up and start building workflows without talking to anyone or entering payment details.
How do I get started with Harness?
Sign up free from the Harness page and start building your first workflow right away. If you would like help designing a workflow for your business, the Flyder team is happy to talk it through.
