LearnDash Course Assignments Automator

I want participants in my LearnDash course to fill in assignments while taking the e-learning. Their answers should be automatically collected and, at the end of the course, combined into a personalized Word document (a business plan) without requiring any manual action from the participant (such as downloading or copying).

Specifications:
Input via LearnDash

Participants complete assignments across different lessons. input happens via Gravity Forms (or a similar solution that, for example, connects forms per lesson to the logged-in user). I’m not sure if this is the best approach—if you think there’s a better solution, I’m open to alternatives.

Storage of answers:

Answers must be stored per user.
The structure needs to be logical for combining into a business plan.

Automatic document generation:

After completing all assignments (or upon finishing the course), a Word document should automatically be generated. The document must include the answers, nicely formatted in chapters (such as “Target Audience,” “Marketing,” “Finances”).
No manual action should be required from the participant.

Automatic delivery:

The Word document should automatically be:

Emailed to the participant, or
Made available via a download link, or
Stored in the user’s profile/dashboard.

Use of tools:

I’m using WordPress + LearnDash.
Preferably making use of:
Gravity Forms
E2Pdf (for document generation)
Uncanny Automator (for triggers upon course completion)

Alternatives are complelety fine as long as it all works fully automatically.

Desired outcome:
A participant completes the course → fills in assignments → at the end of the course they receive, without any manual steps, a fully completed Word document (business plan) based on their provided answers.
