If you haven’t come across Tracy yet check it out, it might be useful for you.
Tracy will convert your monochrome sketches, drawings or hand lettering to SVG. You can either drag and drop an image or you can connect the website to your phone via a QR code. Sounds cool, but I haven’t tried that part.
Edit: Please note that you’ll get a clipping path error when uploading to the GFUI. Ignore the error and we’ll see what happens next time the GFUI gets updated.
