2. Click Sign In.
3. After a successful sign-in, you will enter Workspace.

3.3 Account-level isolation

Each teacher account has its own workspace. The following assets are isolated per account:

• Decks
• Baseline outputs
• Interactive Prep outputs
• Reference Materials
• Sessions

4. Workspace Overview

After signing in, you will land in Lectura Workspace, the main console for teachers and content creators.

4.1 Main Workspace entries

5. Uploading a Presentation

5.1 Supported formats

• PPTX
• PDF

5.2 Upload workflow

1. Go to the upload section in Workspace.
2. Select a local PPTX or PDF file.
3. Optionally fill in Name for this talk or course.
4. After upload, the deck appears in your presentation list.

5.3 Naming recommendation

• Use a course name, report title, or project title as the display name.
• If you have multiple versions, add a date or version tag.

6. Generate Baseline

Baseline is the first complete speaking draft generated for a deck. It serves as the foundation for Interactive Prep.

6.1 Why Baseline matters

• It creates an initial script for every slide.
• It provides a starting point for rehearsal, revision, and question handling.
• It gives the full deck a consistent first-pass structure.

6.2 When to use it

In most production workflows, you should generate the Baseline first and then move into Interactive Prep.

6.3 Basic steps

1. Select an uploaded deck in Workspace.
2. Click Generate Baseline.
3. Wait while the system generates baseline drafts for the full presentation.
4. When complete, move to Interactive Prep.

7. Interactive Prep

Interactive Prep is the main preparation stage in Lectura. It allows you to refine slide scripts until they are ready for formal delivery.

7.1 How to access it

• Open it directly from Workspace.
• Or click Interactive Prep for a specific deck in the deck list.

7.2 Main elements on the page

• Deck selection
• Lecture draft set selection
• Current slide preview
• Saved draft and audio assets
• Interactive Prep session controls

7.3 Main controls

7.4 Recommended workflow

1. Generate the Baseline.
2. Open Interactive Prep and review the deck slide by slide.
3. Refine key slides with AI revisions or human lecture capture.
4. Use Accept as Standard for final versions.
5. Make sure you end up with a complete lecture draft set for session creation.

7.5 Translation

Once a revised asset is ready, you can translate it into another language to create a translated lecture draft set.

• Translation is available only for revised assets.
• The translation applies to the full lecture draft set, not just one slide.
• The translated set can then appear in Create Lecture Session.

7.6 Discussion option

You can decide whether the session should automatically enter a final discussion stage after the last slide.

8. Reference Materials

Reference Materials improve answer quality by giving the system additional grounded context.

8.1 Supported material inputs

• Pasted text
• PDF (text-readable)
• DOCX
• TXT / Markdown

8.2 Not recommended

• Image-only PDFs: if text cannot be extracted, they cannot support grounded Q&A.
• Very large files: keeping materials around 10 pages or fewer is generally recommended.

8.3 Scope options

8.4 Current answer priority

1. Current slide content
2. Uploaded reference materials
3. The rest of the deck
4. Cautious LLM inference
5. I don’t know

9. Create Lecture Session

The Teacher page is the operational page used by the presenter or instructor to control a session.

10.1 AI-led teacher page

• Mainly used to start, stop, and observe the session.
• AI handles the question-answering flow.
• The session resumes automatically after AI-led Q&A.

12. AI-led vs Teacher-led

13. Manage Sessions

The Manage Sessions page lets you review and clean up your own sessions.

13.1 Available actions

• View all sessions
• Open Teacher Page
• Open Audience Page
• Copy Link
• Select all / Delete selected

13.2 Deletion note

Deleting a session is permanent and removes its associated session records.

14. My Account

Each user can open My Account from the Workspace header.

14.1 What is shown

• Current account email
• Account status (Active / Frozen)
• Deck count
• Session count
• Disk usage
• Tracked LLM tokens
• New decks and sessions in the last 7 days
• Last activity time
• Account creation time

14.2 Change password

1. Open My Account.
2. Enter a new password in the Password section.
3. Click Update Password.

14.3 Storage warning

If the account uses more than 1 GB of storage, the page displays a warning indicating that older files may need to be removed to keep the workspace stable.

15. Admin Page

The Admin page is available only to the administrator account.

15.1 What an administrator can do

• View all registered accounts
• See each account’s deck count, session count, disk usage, and LLM usage
• Search and sort accounts
• Update another user’s password
• Freeze or reactivate accounts
• Delete accounts

15.2 Deleting an account

Before deleting an account, the system shows how many decks and sessions owned by that account will be removed.

16. Resource Usage and Model Usage

16.1 What is tracked

• Deck count
• Session count
• Disk usage
• LLM token usage

16.2 Token usage scope

The platform aims to track usage across:

• Baseline generation
• Interactive Prep text generation
• Translation
• Text Q&A
• Realtime Q&A
• Realtime lecture delivery
• TTS / ASR related model calls

16.3 Why some numbers are estimates

Some audio APIs do not always return full token usage information, so part of the usage shown in the admin and account pages may be estimated rather than directly reported by the provider.

17. Recommended Workflows

17.1 Standard teacher workflow

1. Upload Presentation
2. Generate Baseline
3. Interactive Prep
4. Reference Materials
5. Create Lecture Session
6. Share the Audience Link

17.2 Conference or technical presentation workflow

1. Upload the final deck
2. Generate the Baseline
3. Use Interactive Prep to refine the delivery script
4. Upload supporting notes or documents to Reference Materials
5. Translate the final lecture draft set if needed
6. Create an AI-led or Teacher-led session

18. Common Issues and Troubleshooting

18.1 Registration says email verification is not configured

This means SMTP email sending has not been configured yet and must be set up by the administrator.

18.2 A PDF cannot be used for Q&A

If the PDF is image-based or unreadable, the system will warn that it cannot be used for grounded Q&A.

18.3 Baseline generated, but preview audio later failed

Preview audio rendering is best-effort. If the baseline drafts have already been created, a small preview audio failure does not necessarily block the main workflow.

18.4 No audio on the teacher or audience page

• Check whether the browser blocked autoplay audio.
• Check microphone and audio permissions.
• Confirm that the session is currently in a state that allows Q&A or discussion.

18.5 Why can’t I create a session directly from Baseline?

The platform requires at least one complete Interactive Prep lecture draft set to help ensure session delivery quality.

19. Storage and Cleanup Recommendations

Over time, the following data can grow significantly:

• Uploaded decks
• Generated audio assets
• Interactive Prep revisions
• Reference Materials
• Sessions and related Q&A records

Recommended cleanup habits:

• Delete sessions you no longer need
• Delete unused decks
• Monitor per-account disk usage regularly

20. Closing Note

The value of Lectura is not only in generating a script. Its real value is in turning one slide deck into a reusable, presentable, answerable, and scalable presentation system.
