Products & Services
GPL-3.0 open-source AI trend and public-opinion radar that aggregates trending topics and RSS, filters and analyzes content, translates it, and delivers reports through multiple notification channels.
Local-first Windows and macOS workspace for region and scrolling screenshots, offline OCR, image annotation, batch PDF recognition, organizing captured material, and LAN sharing.
Android 10+ companion for SanFrame that pairs with a computer on the same LAN to share text, images and files.
Planned interactive toolkit for traditional culture, personal exploration and AI-assisted learning; the public product destination was still being prepared.
Market Position
sansan positions TrendRadar as a self-hostable, AI-enhanced alternative to conventional RSS readers and alert tools: it combines multi-platform trending aggregation, RSS, precise filtering, AI analysis/translation and multi-channel delivery in one pipeline. Its differentiators are open-source GPL distribution, local/cloud-choice deployment and MCP-based conversational analysis. SanFrame similarly emphasizes local-first capture and LAN sharing rather than a cloud-only workspace.

Founders

Founding Story
The official site presents sansan as a personal project and software practice rather than a conventional company. The work is driven by tools the creator actually needs: TrendRadar addresses information overload and trend monitoring, while SanFrame is shaped around capturing, organizing and sharing content; the stated philosophy is to build something useful and keep it interesting.
Business Model
Revenue Model
The open-source TrendRadar is distributed under GPL-3.0. sansan is preparing a separate commercial desktop edition and has described sponsorship-based access as a planned model, but the public site says edition, entitlement and amount details remain provisional.
