Pastea

User reality comes from a HackerNews 'Show HN' launch thread (107 comments collected; top-voted subset shown). Pastea is an MVP that generates social-share thumbnails for blog posts from 4 templates, pulling free Pixabay images (commercial use allowed, no attribution required, per the maker). Reception is mixed-to-constructive. Positives: commenters praised the quick rendering, the prefilled homepage demo links ('TechRadar, AVC, Paul Graham, BBC, Medium, Pulse') — one user said showing tests instead of an empty search box should 'significantly increase conversion' — and the underlying pain point (manually editing thumbnails in image editors is slow). Core criticism: image relevance relies on dumb keyword matching — for Paul Graham's 'The Bus Ticket Theory of Genius' it returned a raffle-ticket image ('basically just doing keyword matches... the images actually have nothing to do' with the article). One user tested two mattgreer.dev articles and 'would not have used any of what it generated'; failures clustered on pages whose hero images were SVG or small (444x444) PNGs. Several users asked for an API and build-step integration rather than ad-hoc per-post use ('once it has an API... I would prefer to receive no image than an unrelated, keyword-matched stock image'). One commenter objected to AI-style branding: 'I don't believe any AI was used for this... not every project requires AI.' The thread surfaced heavy competition: MugshotBot (meta-tag-based), Thumblink (page screenshots), open-source imgmaker (headless Chrome), plus ApiFlash and Statically screenshot APIs — one commenter already auto-generates og:image via Statically in their blog template. Scaling concerns (Puppeteer timeouts, retries) were raised by a founder of a similar product. Note: a minority of top-voted comments in this dataset belong to a separate HN thread about 'justread' (a readability/reader bookmarklet and Boilerpipe discussion) and are unrelated to Pastea.
