Dify guides

Step-by-step guides, appendices and a two-hour workshop on building AI agents in Dify for education. Made by LeX Consultancy B.V. All examples play at Example College (fictional); screens captured on Dify cloud, 20 September 2026.

The screenshots show the English Dify interface and the English build of each app. Guides whose screenshots still come from the Dutch build say so on their first page; those are being replaced one by one.

Every guide has a green "Your choice" box per step (what you replace with your own material, style or prompt) and a closing chapter "Make it yours" with adjustments, assignments and a checklist.

What each app is for

Every guide builds one app. This is what they are meant for and when you choose which.

App What it does For whom Kind Choose this if
Text at level (01) Rewrites a text for a chosen audience or reading level Teachers, communications Workflow You want to learn what a workflow is: fixed steps, one input, one output
School guide assistant (02) Answers questions from parents and students out of the school guide, with sources Reception, form tutors, parents Agent with knowledge base You have a document that keeps getting the same questions
Parent letter assistant (03) Writes a parent letter in the school's style, based on the style guide Teams, heads of year Agent with knowledge base Letters must have one tone and one layout, written by different people
School news (03 and 07) Turns one message into three versions: website, parent app and social; in 07 with a checker and a gatekeeper that rejects what breaks the rules Communications officers Workflow You want to see how an app checks itself before something goes out
Test week planner (04) Makes a study plan for the test week with a student and delivers Excel and a calendar file Form tutors, students (after an impact assessment) Agent Console You want to see what an agent can do that a workflow cannot: decide how, and make files
Transcription tool (05) Turns a recording of a meeting into minutes with decisions and action points Departments, teams Workflow with tool You want a file as input and a tool (speech to text) in a workflow
Materials check (06) Assesses learning material for accessibility (UDL), makes versions for teacher and student and searches for open educational resources Teachers, support coordinators Agent Console with custom tool You want to make your own tool out of a website with an API
Study coach biology (08) Helps a student with explanations, hints and planning on ecology; passes personal questions to the teacher Teachers, students (after an impact assessment) Chatflow You want a conversation with routes, memory and a human in the loop

The order is also a learning path: 01 and 02 in the first hour of the workshop, 03 and 07 when you want to help a team, 05 and 08 when you want to serve a subject, 04 and 06 when you want to know what the Agent Console adds.

Example apps

The apps are live to try out:

Installing the apps in your own Dify

Every Studio app is also in its guide's folder as a file: <name>.dify.yml. That is Dify's DSL export. This is how you put it in your own workspace (online or self-hosted):

  1. Download the .dify.yml file from the folder.
  2. In Dify go to Studio, click Create and choose Import DSL file.
  3. Drag the file into the window and click Create.
  4. At every LLM step pick your own model (the export refers to gpt-5-mini via OpenAI) and under Knowledge attach your own knowledge base; that does not travel with the file. Create it first with the sample document from the same folder (guide 02, steps 1 to 5).
  5. Publish.

The files contain no keys. The Agent Console apps of 04 and 06 have no export (yet); you build those with the guide.

File Guide
01-workflow/text-at-level.dify.yml 01
02-agent-knowledge-base/school-guide-assistant.dify.yml 02 (including the Reception mode from 03)
03-school-communication/parent-letter-assistant.dify.yml 03
03-school-communication/school-news.dify.yml 03 and 07 (version 2, with Checker and Gatekeeper)
05-transcription-tool/transcription-tool.dify.yml 05
08-chatflow-study-coach/study-coach-biology.dify.yml 08

Building or editing yourself

Every folder has the same structure:

guide-*.md            source (edit this)
screenshots/          screenshots, numbered in order
build.py              makes .html, .pdf and .docx from the .md:  python3 build.py

python3 _tools/build_all.py builds everything at once; python3 00-presentation/build.py builds the slides and the PDF of the presentation. python3 _tools/make_samples.py regenerates the fictional sample documents. Needed: python3 with markdown, google-chrome and libreoffice. The PDFs are in git next to the sources; HTML and Word you make yourself with build.py.

Formatting in the sources: numbered list = actions, table "What you type" = field values, code block = type literally (label "Type in"), orange box = pitfall, green box = "Your choice" (a blockquote that starts with Your choice). Layout and logo are in _tools/build_guide.py; replace the logo with that of your own school or organisation.
