SlideSpeak is an online tool for turning documents into presentations. You upload a PDF, Word or PowerPoint file, or paste text, and it builds editable slides from it. What sets it apart is that it starts from an existing document, not an empty topic, so it suits someone who already has a report or article better than general-purpose deck makers. It also offers an API for developers.

What is SlideSpeak good for?#

  • Report to presentation: an employee with a twenty-page report turns it into a short deck for a meeting.
  • Paper or thesis slides: a student pastes the research text and gets a skeleton for the defense slides.
  • Document summaries: upload a long file and read the summary or key points.
  • Asking a document questions: ask about a file's content without reading all of it.
  • Using your own template: apply your organization's PowerPoint template so output fits the company identity.
  • Integrating into your software: a developer adds slide generation to a product through the API.

Strengths and weaknesses#

Strengths:

  • Starts from an existing document instead of from scratch.
  • Editable PowerPoint output.
  • Summaries and Q&A alongside slide creation.
  • An API for integration.

Weaknesses:

  • Right-to-left text and non-Latin layout is not reliable.
  • Automatic summaries may miss important points.
  • The free plan is limited.
  • Slide design is simple and not enough for marketing-grade decks.

Free version and pricing#

SlideSpeak is freemium: a free version for trying it with limits on presentations and file size, and a subscription for larger files and fuller features. Check the official site for current prices.

Language support#

The tool is built for the English-speaking market. It works with files in other languages, but summary quality and the look of right-to-left text drop in the slides. If you need a non-English deck, fix the output in PowerPoint.

We have no confirmed information on access from Iran, so it is listed as unknown.

Getting started in three steps#

  1. Upload your file or paste your text.
  2. Choose the number of slides, tone and language.
  3. Edit the result in the editor or PowerPoint and save it.
