## Chatbox

Chatbox is a multi-model AI client rather than a model of its own. Instead of locking you into a single provider, it connects to the APIs you already pay for — GPT, Claude, Gemini, Grok, DeepSeek and a long list of others — and gives them a single, consistent workspace. Because you supply the keys, your conversations run against your own accounts and quotas, and Chatbox states plainly that it does not sell or share your data. The app ships for Windows, macOS (Apple Silicon and Intel), Linux, iOS and Android, and there is also a browser version, so the same conversations and settings follow you between devices.

The everyday workflow is chat-plus-files. You can drop in PDFs, Word documents, spreadsheets, images and code snippets and ask questions about them, then quietly build a local knowledge base so the app remembers and retrieves your own documents over time. A live web search mode pulls current information for questions where the model's training cutoff is not enough, and the rendering layer handles Markdown, Mermaid diagrams and LaTeX formulas properly, which matters for technical and academic work.

More recently the product has been pushing beyond plain chat with Work Mode, an agentic layer where an assistant can work with your files, search the web, write and preview code and run tools with less babysitting. There is AI image generation for turning prompts into visuals, plus code generation with live preview for quick prototyping. A free tier covers standard use, and paid plans raise limits or add hosted features aimed at heavier users; the desktop app itself can still be used with your own API keys.

**Pricing & Plans:** Freemium: a free tier covers everyday chatting, with paid subscription plans that lift usage limits and add hosted AI capabilities. Bringing your own model API keys keeps costs tied to your provider.

- **Multi-model support with your own keys:** Switch between GPT, Claude, Gemini, Grok, DeepSeek and many other providers in one client by plugging in your own API credentials.
- **File, image and document Q&A:** Upload PDFs, Office documents, images and code, then ask the app to summarise, explain or extract what you need.
- **Local knowledge base:** Store documents locally so Chatbox can recall and answer from your own materials while your data stays on your machine.
- **Live web search and rich rendering:** Pull current results from the web and display answers with Markdown, Mermaid diagrams, LaTeX formulas and code previews.
- **Work Mode agents and image generation:** Let an agent handle multi-step tasks with your files and tools, and generate images directly from prompts.

**Strengths:** Supports many leading models in a single interface, so you are not locked into one provider; Available on Windows, macOS, Linux, iOS, Android and the web; Local knowledge base and clear privacy positioning keep your documents on your device; Handles files, images, web search, code preview, LaTeX and Mermaid out of the box

**Limitations:** Best experience with your own API keys, which means managing separate provider accounts and billing; Model availability and quality depend entirely on which providers you connect; The breadth of modes and settings can be overwhelming for someone who just wants a simple chat window

## Grammarly

Grammarly is the world's most widely deployed AI writing and communication platform, trusted by more than 40 million daily users and 50,000 organizations including Atlassian, Databricks, and Zoom. Operating as a persistent overlay across over 500,000 web applications, desktop programs (Windows and macOS), Microsoft Office, Google Docs, and iOS/Android keyboards, Grammarly analyzes text in real time to eliminate grammatical errors, streamline wordy phrasing, and calibrate tone to match the writer's intent. Following its corporate evolution under the Superhuman Platform umbrella alongside Superhuman Mail and Coda, Grammarly has expanded from a personal proofreader into an enterprise-grade proactive AI communication suite.

In 2026, Grammarly goes well beyond red-underline spellchecking with a suite of specialized AI Agents and document integrity tools. Writers can invoke purpose-built agents—including AI Grader, Citation Finder, Reader Reactions, and Paraphraser—alongside generative AI drafting directly inline where they work. To address academic and professional transparency in the generative AI era, Grammarly offers built-in Plagiarism Detection, an AI Detector, and Grammarly Authorship, which tracks how a document was constructed by automatically categorizing text as human-typed, pasted from external sources, or generated/modified with AI. For teams, Grammarly enforces organizational consistency through custom Style Guides, Brand Tones, reusable Snippets, and Knowledge Share.

Grammarly simplified its subscription structure by consolidating its legacy individual 'Premium' and team 'Business' offerings into a single unified tier: Grammarly Pro. The Free plan ($0/month) covers essential spelling, punctuation, basic tone visibility, and 100 generative AI prompts per month. Grammarly Pro is priced at $12/member/month when billed annually ($144/year) or $30/member/month when billed monthly ($60 quarterly), unlocking unlimited personalized fluency suggestions, full-sentence rewrites, tone adjustment, citation formatting, plagiarism and AI detection, 1 team style guide, and 2,000 generative AI prompts per member each month. Large organizations opt for Grammarly Enterprise (available with Superhuman Go) for unlimited AI prompts, SAML SSO, SCIM provisioning, Data Loss Prevention (DLP), and Bring Your Own Key (BYOK) encryption.

**Pricing & Plans:** Free plan ($0/month) includes core grammar and spelling checks, tone detection, and 100 generative AI prompts/month; Grammarly Pro costs $12/member/month billed annually ($144/year, or $30/month billed monthly) with full-sentence rewrites, plagiarism/AI detection, team style guides, and 2,000 AI prompts/month, while Enterprise offers custom pricing with unlimited AI prompts and BYOK security.

- **Ubiquitous Inline Rewriting & Tone Calibration:** Works natively inside Chrome, Safari, Firefox, Edge, Windows, Mac, Google Docs, MS Office, and mobile keyboards to flag grammar mistakes, rewrite tangled sentences, and shift tone toward confident, empathetic, or executive registers.
- **Specialized AI Agents (AI Grader, Citation Finder & Reader Reactions):** Deploys contextual AI agents that predict how a target audience will react to a draft, locate credible supporting citations, grade essays against rubric criteria, and generate drafts using up to 2,000 monthly prompts on Pro.
- **Grammarly Authorship, AI Detector & Plagiarism Checker:** Scans text against billions of web pages and academic databases for accidental plagiarism, detects AI-generated passages, and logs transparent document provenance via Authorship reports in Google Docs and Word.
- **Team Style Guides, Brand Tones & Knowledge Share:** Enables teams on Pro and Enterprise plans to codify company terminology, ban deprecated jargon, enforce inclusive language, insert shared Snippets, and surface internal company definitions inline.
- **Enterprise Security, DLP & Superhuman Platform Governance:** Protects organizational data with SOC 2 Type 2 attestation, SAML SSO, SCIM lifecycle management, Confidential Mode, Data Loss Prevention controls, Audit Logs API, and customer-managed BYOK encryption.

**Strengths:** Frictionless cross-platform integration works inside virtually every browser, desktop app, email client, and mobile OS without copy-pasting into a separate chatbot.; Consolidating Premium and Business into Grammarly Pro ($12/member/month annual) gives individuals and small teams access to style guides, analytics, and plagiarism/AI detection in one plan.; Grammarly Authorship provides a constructive, transparent audit trail for students and writers to demonstrate human writing integrity alongside responsible AI editing.; Mature enterprise security posture featuring BYOK encryption, Data Loss Prevention, and granular application/domain blocklists.

**Limitations:** Month-to-month billing on Grammarly Pro is steep at $30/member/month compared to the $12/member/month annual commitment ($144 billed upfront).; Core writing intelligence and style rules remain primarily optimized for English dialects (US, UK, Canadian, Australian, Indian) rather than native multilingual grammar checking.; Aggressive inline underlines and pop-up agent cards can feel visually intrusive in dense technical documents or code-heavy web editors unless muted per domain.
