Shadow Save Bot solves a practical and frequent problem by enabling users to download media without watermarks across multiple platforms. However, its audience reach and traction are minimal, currently sitting at just 35 users. While the high retention rate (66%), transparent reporting, and scalable provider-based architecture demonstrate a solid technical foundation, the project is still in a prototype stage and competes in a highly saturated market.

Description
A Telegram bot for downloading TikTok, Instagram, and X content in the highest available quality, with watermarks stripped.
Audience Reach
People who want to save videos/images from TikTok, Instagram, and X without watermarks or platform restrictions(like X premium download gating, or tiktok no-download settings), content creators repurposing clips, social media managers archiving content, or just regular users who want to save something before it disappears or gets taken down.
Target Users
35 total users, 23 weekly active (66% weekly retention), 441 downloads processed to date. Usage spans all three supported platforms — TikTok leads at 274 downloads, then Instagram at 95, Twitter/X at 72, showing organic, cross-platform pull rather than reliance on one source. Growth has been organic so far (community showcase via HNG and a few twitter posts), not paid acquisition.
