Notes2Pic's answer:
Notes2Pic's answer:
Notes2Pic offers the ability to paste the content directly inot a textarea in-studio rather than waiting to make a tweet first and pasting the link afterwards. This allows users to create tweets/Substack Notes and Instgram content at the same time without waiting for the short-form content to drop first.
Notes2Pic's answer:
The ability to convert long-form content and essays to threads instantly, and generate Instagram carousels from it at the same time.
Notes2Pic's answer:
I, Jeruel Richard — founder and CEO, was looking for a cheaper alternative to Pika whilst repurposing my Substack Notes to Instagram. Using Gemini to create the images got exhausting and painfully slow really quick, so i decided to build a tool that creates me the images with pasted content, in seconds.
