Briefy vs SciSummary

Briefy turns lengthy content into structured summaries and stores them in a knowledge base for later review. It can produce overviews, tables, mindmaps and timelines from websites, videos, email threads, podcasts and PDFs. Users can save, review, search, ask questions about and share briefs, and navigate back to the source material to check details. Briefy supports multiple languages and inline translations. Its Gmail feature is described as an email copilot for skimming threads and composing replies. The product is available as an extension, on iOS and macOS, and on the web. PDF summarization requires Premium or Ultra, with respective file-size caps of 20MB and 50MB; YouTube summaries currently require subtitles. The free plan lists 30 credits per month. Premium is listed at $89.88 a year, billed annually; Ultra is $167.88 a year, billed annually. The pricing page says new subscriptions and credit purchases are no longer available, and both paid plans are marked unavailable for new subscriptions.

SciSummary uses AI to help scientists, researchers, and students understand scientific papers through summaries, analysis, and extracted insights. Summaries are organized into abstract, methods, results, and conclusion sections. It can combine multiple papers into one summary and compare them, while folders and tags organize a research library. Figure chat interprets p-values, confidence intervals, and effect sizes. The service extracts abstracts, figures, and references and highlights key findings. Its web and API access includes a bulk API accepting PDFs, links, or full text, with hundreds of documents supported in one request. A REST API includes an official CLI and generated SDK clients from its OpenAPI specification. An MCP server connects with Claude Desktop and ChatGPT. SciSummary also summarizes webpages and accepts file uploads. Pricing is paid, starting at $4/mo (annual), with a 7-day trial and no standard free plan.
