What files work with Flow AI?

Quick Snapshot (TL;DR)

The 6 most important rules:
  1. PDFs only, plus text from Page Builder in courses.
  2. Maximum 50 MB per PDF
  3. Text must be copyable. No scanned or image-only PDFs
  4. Processing time is instant for small files and up to about 15 minutes for large PDFs
  5. Structure matters. Use clear headings, FAQ format, and focused topics
  6. Split large documents. Topic-based PDFs perform far better than one large file

About Flow AI

Edbound AI (formerly Knorish) AI agents help you support your audience by automatically answering questions about your programs, courses, etc, while guiding users toward the right next steps. This FAQ explains how to prepare and upload content so Edbound AI’s AI agents can deliver accurate, reliable answers.

Supported Content Types

Edbound AI’s AI agents currently learn primarily from two types of content:
  1. PDF documents uploaded inside a course curriculum
  2. Text-based content created using the Page Builder inside courses
If the text cannot be selected or copied, the AI agent cannot read it.
Info
Important note: Videos are not parsed yet. Images inside PDFs may appear visually, but the AI may not understand them. Downloadable PDFs added only as attachments are not used for AI training

What types of content work best?

Recommended document types include:
  1. Course FAQs and troubleshooting guides
  2. Refund, cancellation, and policy documents
  3. Program overviews and curriculum explanations
  4. Student onboarding handbooks
  5. Pricing and payment information
  6. Technical support guides
  7. Product or feature documentation
  8. Internal SOPs and company policies

PDFs vs Page Builder content

  1. Use Page Builder content for shorter or frequently updated information, such as FAQs or instructions
  2. Upload PDFs for longer or pre-existing documents, such as handbooks or policy guides
Both formats are equally valid when structured well.

How to Structure Content for Accurate Answers

Well-structured content leads to more precise answers, fewer generic responses, and better handling of edge cases. Best practices:
  1. Use descriptive titles and headings that match real user questions
  2. Maintain a clear hierarchy (H1, H2, H3)
  3. Prefer FAQ-style sections where possible
  4. Keep each document focused on one main topic or audience
  5. Avoid mixing pricing, policies, onboarding, and marketing content in one file
  6. If a human can quickly scan the document and find an answer, the AI agent usually can too.

Handling Large or Complex Documents

If a document is very long or covers multiple topics, splitting it improves AI accuracy. Recommended ways to split content:
  1. By topic (for example, Payments, Course Access, Certifications)
  2. By audience (Students, Instructors, Admins)
  3. By update frequency (frequently changing content separate from stable content)
Rule of thumb: If a user asks about refunds, they should not have to search through curriculum or marketing information.

How to Upload Content for AI Training

Uploading PDFs


  1. Go to Dashboard > Courses
  2. Select an existing course or create a new one
  3. Add the PDF inside the course curriculum
  4. Upload the file
Processing happens automatically. Small files are processed quickly, while larger files may take up to about 15 minutes.

Training the AI without exposing content

If PDFs are added only to train the AI agent, place them inside an unpublished course.

Using Page Builder content

All text added through the Page Builder inside courses is automatically available to Edbound AI’s AI agents.

Troubleshooting and Common Questions

  1. My PDF is larger than 50 MB. What should I do?
    1. Split the document by topic, remove unnecessary pages, or compress it carefully while ensuring the text remains selectable.
  2. My PDF is mostly images or scanned pages.
    1. Recreate the content as text, convert it into an editable text-based PDF, or rewrite the most important questions and answers into a clean FAQ-style document.
  3. Can I upload Word docs, Google Docs, or web pages?
    1. Not directly. Export or save them as clean, text-based PDFs, or paste the content into Page Builder pages.
  4. How often should I update my content?
    1. Update frequently changing content such as pricing or promotions more often. Stable policies and evergreen FAQs can be updated less frequently.
  5. How can I test if my content will work?
    1. Open the PDF and try highlighting and copying the text. If it is readable and structured, it will usually work well. Additionally, you can also upload your PDF, wait for it to be ingested by the AI and then ask a question pertaining to the PDF. Check for the accuracy and completeness of the answer.
