## OthersideAI (HyperWrite)

OthersideAI is the company behind HyperWrite, an AI writing assistant that has become one of the better-known productivity tools for writing on the web. Visiting the old othersideai.com address now redirects to hyperwriteai.com, which is the product's current home — so the listing refers to the same assistant under its newer brand.

The product is built around a Chrome extension that injects AI assistance into whatever you are already writing. TypeAhead completes your sentences as you type, the Email Responder expands a short intent into a full Gmail reply, and AutoWrite generates paragraphs on demand. Beyond the extension there is a web app with a document editor, a chat interface and a library of hundreds of pre-built AI tools — rewriting, simplifying, speech writing, content generation — plus the ability to create custom tools for recurring workflows.

For research-heavy writing, Scholar AI searches millions of scholarly articles and papers to ground answers in real sources, and paid tiers add citations with real-time information. Pricing is tiered: a Premium plan around $20 per month with a monthly AI message allowance and three custom personas, and an Ultra plan around $45 per month with unlimited AI messages and ten personas. Annual billing lowers the effective monthly rate.

**Pricing & Plans:** Freemium with tiered monthly subscriptions. Premium (roughly $19.99/month, or about $16/month billed annually at $192/year) includes 250 AI messages per month, citations with real-time info, three custom personas, unlimited TypeAhead and the full tool library. Ultra (roughly $44.99/month) adds unlimited AI messages, ten personas and first access to experimental features.

- **TypeAhead autocomplete everywhere:** Personalised, context-aware sentence completions as you type inside Gmail, Google Docs and other sites through the Chrome extension.
- **Email responder:** Turn a few words of intent into a full, appropriately toned reply directly inside Gmail.
- **Hundreds of AI tools and templates:** Pre-built tools for rewriting, explaining, speech writing, content creation and more, alongside custom tools built for your own workflows.
- **Scholar AI research mode:** Searches scholarly articles and papers in real time so output is backed by accurate, current and citable sources.
- **Document editor and chat:** A collaborative AI writing space plus chat for brainstorming, rewriting and problem solving.

**Strengths:** Works inside the tools you already use rather than forcing a new app; Large library of pre-built tools plus custom tool creation; Scholar AI grounds research-heavy writing in real, citable sources; Free tier available so you can test the core experience before paying

**Limitations:** The best capability — unlimited messages, personas, citations — sits behind paid tiers; Free and entry tiers cap AI messages per month; Coverage is strongest in the browser, with limited reach into desktop apps such as the Microsoft Office suite

## 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
