## 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

## Unearthed

Unearthed is a reading memory tool. It focuses on the problem that highlights are easy to save and hard to find again: you remember an idea but not the book it came from. By collecting Kindle and KOReader highlights into one library, it lets you search a few words and jump back to the passage, with notes kept alongside it in your existing note-taking app.

The project deliberately offers multiple editions so you can match it to where you read and where your notes live. Unearthed Local is a one-time-purchase desktop app for Windows, macOS and Linux that stores your library on your own computer, exports Markdown to an Obsidian vault and connects to Craft, and also saves articles and RSS feeds. Unearthed Online is a $5/month browser edition that is open source under GPL-3.0 and connects to Obsidian and Notion while sending daily reflections to Supernotes. Unearthed Mobile is a paid phone app for reading articles and capturing passages on the go.

Beyond books, Unearthed supports your own sources so that quotes, ideas and facts that did not come from a book still live in the same system, and daily reflections bring saved passages back for another look. It is positioned as a Readwise alternative with a strong open source and self-hosting story, though AI summaries and book chat are limited to the Online subscription and the Capacities integration is still pending.

**Pricing & Plans:** Free/open source core with paid editions. Unearthed Online costs $5 per month. Unearthed Local for Windows, macOS and Linux is a one-time purchase, and Unearthed Mobile is a separate one-time purchase app, with no Obsidian plugin required for Local exports.

- **Kindle and KOReader sync:** Import Kindle and KOReader highlights into a single searchable library, so you can find a passage without reopening every book.
- **Notes app integrations:** Send books, highlights and daily reflections to Obsidian, Craft, Notion and Supernotes, with Capacities support in the works.
- **Custom sources for your own ideas:** Create your own sources for quotes, ideas and facts so short-form inspiration sits beside your book highlights.
- **Articles and RSS feeds:** Save web articles and follow RSS feeds in Unearthed Local and Mobile so new posts appear next to your reading highlights.
- **Open source and self-hostable:** Unearthed Online is GPL-3.0 open source, with the browser extension, Obsidian plugin and KOReader plugin published on GitHub.

**Strengths:** Consolidates Kindle and KOReader highlights into one searchable library; Connects to Obsidian, Craft, Notion and Supernotes; Open source (GPL-3.0) with self-hosting options; Local edition keeps your library on your own computer

**Limitations:** AI summaries and book chat are only on the Online subscription, and Capacities support is not yet available; Local and Mobile editions are separate paid apps, not one purchase for everything; Core focus is Kindle and KOReader, so other e-readers get less coverage; Online edition depends on a monthly subscription for continued web access
