Hey this is Tan, I'm the creator of NotesBot. I created this tool because I needed it for my own meetings. After using myself and getting great summarization reviews from my peers, I decided to release it to the public. After release, we realized people were also using it for Dungeons and Dragons, I then added a DnD mode. This tool is non-invasive, very easy to set up, and perfect for meetings. I hope you enjoy using it!

Hi folks - I'm Charles, the founder of Wizardly. As a sales guy I originally built this app to create training videos for sales reps 10X faster. Many friends started using Wizardly to create all sorts of tutorials for tools I'd never heard of. Excited to get feedback and hear how I can make this app the best how-to video generator on the market.

Mention your product or service in social media comments using our accounts.OpenListening4 has truly impressed me! What sets it apart from other social listening tools is its semantic matching technology, rather than traditional keyword-based matching. This difference is game-changing! While conventional tools only find content containing specific keywords and often miss relevant discussions using different terminology, Listening4 actually understands the meaning and context behind language. Even when prospects describe the same need using completely different words, it accurately identifies them. Through this platform, I've discovered numerous high-quality leads that traditional keyword searches would never have found. This semantic understanding capability has elevated my sales efficiency to a whole new level. Highly recommended!
