Based on your query, I would recommend a combination of Otter.ai and Tome.

Otter.ai can transcribe your verbal information into text. It's a powerful tool that can convert spoken words into written text, making it ideal for capturing lectures, meetings, or brainstorming sessions. It also offers real-time transcription, audio playback, and shareable content, which can be beneficial for revisiting and sharing your verbal information.

Once you have your transcriptions, you can use Tome to transform these into visually rich presentations. Tome uses AI to generate interactive narratives from short prompts, which could be your transcriptions from Otter.ai. It also offers seamless media integration, allowing you to enhance your presentations with images, videos, and more.

By using these two tools together, you can effectively create a presentation from information you shared verbally three weeks ago.
