Poggers OyProject overview
Vainuri writes your secondhand listing for you: enter a product name and a few photos, and the in-app AI assistant produces a ready-to-post listing — platform-tailored titles and copy, a price estimate with negotiation tips, and feedback on the photos. Tri-lingual (fi/en/sv).
A sales listing from photos and product details
Vainuri is an AI-assisted tool for secondhand sellers. The user enters a product name and a few photos, and the in-app assistant “Myyvä” turns them into a ready-to-post listing: a platform-tailored title and description (Tori.fi style plus shorter variants for Vinted, Huuto and Facebook), a web-search-grounded price range and negotiation strategy, and concrete feedback on the photos. The UI is tri-lingual (Finnish/English/Swedish).
A serverless product shipped to production
Built as a serverless architecture on AWS with SST: a React and TypeScript front-end, back-end services on AWS Lambda and DynamoDB, authentication with Cognito, photos in S3 and payments via Stripe. Listing copy and image analysis are generated with Anthropic’s Claude model. A complete product from design to production.
