Blobu

The interesting thing about Blobu is the framing, not the artefact. Its stated premise — that summarising a book in isolation loses the connections between books, and that blending several summaries into one mashup would surface those connections — is a real gap in the market. Tools like Blinkist and Shortform optimise for depth on one title; the synthesis step across titles is largely left to the reader. What exists right now, though, is one paragraph. The homepage says the platform is being rebuilt "from the ground up" and will be back "in a few months—smarter, sharper, and ready to absorb whatever knowledge you throw at it." That phrasing suggests an ambition broader than book summaries, but the page doesn't say what the rebuilt product will actually do, what corpus it draws on, or how the mashups would be generated or attributed. There are no sample outputs to judge quality on — which matters enormously for a synthesis product, because the hard part isn't producing a paragraph, it's producing one that correctly represents what each author actually argued and honestly flags where the comparison is thin. Practical guidance: if you have a reading list and a deadline, use a working tool and treat Blobu as a bookmark. The email address on the page is the only channel you have to ask when the relaunch lands. When it does, evaluate it the way you'd evaluate any summariser — check whether the mashups cite passages you can verify, whether they distinguish agreement from forced similarity, and whether the underlying summaries are accurate on a book you already know well. Until there are examples to inspect, there's no basis for a stronger recommendation than that.
