## DROP

DROP is a lightweight alternative to traditional large-file senders. It runs entirely in the browser: you choose files or a folder with the plus button, review the list, and start the upload while the progress indicator tracks the actual bytes sent. Once the transfer completes you register or sign in — via Google or an email code — to unlock your share link, and the recipient needs no account at all.

The service is designed for handing over photos, finished videos and documents. Folder uploads preserve relative paths, so recipients can either grab individual files or hit "Download all" for a single ZIP that keeps the folder structure; empty folders are not retained. Supported previews include common images, PDF, browser-playable video and audio, and text, while Office and OpenDocument previews depend on an available conversion service and are capped at 64 MiB for the original file.

The limits are clearly published rather than hidden behind a paywall: one transfer can hold up to 10 GB across 1 to 1,000 files, anonymous uploads stay available for 24 hours from creation, and signing in can extend an owned upload to 72 hours from the original creation time. Once a transfer expires the link stops working and background cleanup removes the originals, previews and unfinished upload parts. Files are stored on Cloudflare R2.

**Pricing & Plans:** Free to use — the site publishes no paid tier, no subscription and no per-transfer fee for the documented 10 GB / 1,000 file limits.

- **Large transfers up to 10 GB:** Send up to 10 GB in a single transfer, with support for 1 to 1,000 files per upload.
- **Folder uploads without zipping:** Choose a folder directly in a browser that supports folder selection; relative paths are preserved so recipients get the structure back as a ZIP.
- **No account needed for recipients:** Upload first, then sign in with Google or an email code to unlock the link — anyone with the link can download without registering.
- **In-browser previews:** Recipients can preview common images, PDF, playable video and audio, and text before downloading, with Office/OpenDocument previews when the conversion service is available.
- **Transparent expiry rules:** Anonymous transfers expire 24 hours after creation; a verified sign-in can extend an owned upload to 72 hours from its original creation time.

**Strengths:** Free with a genuinely large 10 GB ceiling and no account required to upload; Folder uploads keep their structure, so recipients do not have to reassemble anything; Recipients never need to register, which removes friction for one-off transfers; Published, explicit limits and expiry behaviour instead of vague fine print

**Limitations:** Retention is short — 24 hours anonymous and 72 hours signed in — so it is not long-term storage; Anyone holding a valid link can download before expiry, so links must be shared carefully; Office and OpenDocument previews depend on a conversion service and are limited to 64 MiB originals

## SciSpace

SciSpace began as a typesetting and paper-formatting service called Typeset and has since grown into a broad AI research platform. Its core promise is that a researcher can move from finding a paper to understanding it to citing and writing about it without leaving one workspace. The platform indexes scholarly content from sources such as Google Scholar, PubMed and arXiv, and layers AI agents on top for reading, extracting data and synthesis.

The signature capability is conversational reading: you upload or open a PDF, then ask questions, highlight confusing sentences for plain-language explanation, or request structured summaries of methods, results and limitations. Around that sit task-specific tools — Literature Review, AI Writer, Paraphraser, Citation Generator, AI Detector, AI Humanizer, Extract Data and a Plagiarism Checker — plus a Chrome extension that adds the same assistant on top of publisher pages and a mobile app for reading on the go.

Access follows a freemium model: exploring and limited usage are free, while paid Premium, Advanced, Max and Enterprise plans raise model quality, credit limits and parallel agent capacity. The company is registered as PubGenius Inc. in Milpitas, California, and markets the product to individual researchers as well as universities and enterprises with SSO and admin controls.

**Pricing & Plans:** Freemium. A free tier with limited usage sits alongside paid Premium (~$12/month billed annually), Advanced (~$70/month) and Max (~$160/month) plans; monthly billing is higher. Enterprise pricing is custom. All plans advertise a 24-hour money-back guarantee, and annual billing carries a discount.

- **Chat with PDF:** Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
- **Literature Review and paper search:** Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
- **Writing, paraphrasing and citations:** An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
- **Extract Data and AI Detector:** Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
- **Chrome extension and mobile app:** Use the same assistant on top of publisher sites and PDF pages via the browser extension, or read and query papers from the mobile app.

**Strengths:** Combines paper discovery, reading, writing and citation tools in one place instead of five separate subscriptions; Conversational explanations of difficult passages are genuinely useful for non-native English readers and cross-disciplinary work; Covers widely used scholarly sources such as Google Scholar, PubMed and arXiv; Free tier plus a Chrome extension make it easy to evaluate before paying

**Limitations:** Credit-based limits can be confusing, and heavy users report hitting caps on the cheaper plans; Model access varies by tier, so the cheapest paid plan does not get the strongest reasoning models; AI-generated reviews and paraphrases still need careful human checking for accuracy and citation integrity
