How Engineers Use AI for Lightning Talks

How are engineers using AI when preparing lightning talks?

• AI is useful for ideation and structuring

• But the core story must come from the speaker

• For lightning talks, AI works best as an editor, not an author

• In English-speaking communities, AI is often used for efficiency

• In Japanese communities, AI is often used to clarify and verbalize rough ideas

• Topic brainstorming

• Outline generation

• Title ideas

• Slide copy

• Diagram ideas

• Speaker notes

• Rehearsal questions

• Translation and English polishing

• Using ChatGPT or Claude to create outlines

• Generating speaker notes and talk flow

• Combining AI with Marp, Reveal.js, or Google Slides

• Turning blog posts or README files into talks

• Treating the result as “AI-assisted, human-edited”

• Turning Qiita or Zenn articles into LT slides

• Asking AI for better titles and openings

• Reordering ideas into a more understandable flow

• Shortening slide text

• Creating English titles or abstracts

Paste an article or README.

Ask AI to:

• Compress it into a 5-minute talk

• Add missing context for the audience

• Break it into one message per slide

Paste rough personal notes.

Ask AI to:

• Find the core message

• Suggest title candidates

• Remove unnecessary details

• Create a stronger closing line

Use AI before rehearsal.

Ask AI to:

• Generate likely questions

• Find points beginners may not understand

• Detect risky or misleading wording

• Check whether the talk fits within 5 minutes

• Personal failure stories

• Real engineering context

• The messy reasons behind decisions

• Team-specific atmosphere

• Timing, pauses, and humor

• The story becomes exaggerated

• The argument becomes too safe

• The slides feel generic

• Personal experience disappears

• The speaker ends up reading someone else’s words

The speaker owns:

• Experience

• Question

• Failure

• Friction

• Conclusion

AI helps with:

• Structure

• Compression

• Rewording

• Flow

• Rehearsal

An AI tool for lightning talks should not simply generate slides.

It should help the speaker:

• Clarify their intent

• Avoid over-polished AI writing

• Create lightweight Markdown slides

• Work locally when needed

• Preserve the speaker’s own voice

AI-assisted lightning talks are not about letting AI do the talking.

They are about using AI to organize messy thoughts.

The main character is still the speaker’s own experience.
