## Devana (Devana.ai)

Devana is a sovereign AI Operating System aimed at organisations that cannot hand their data or their AI decisions to third-party clouds. Rather than solving one isolated task, it acts as a control layer above models, agents, retrieval systems and document pipelines: teams design AI workflows through a visual, no-code interface, connect data sources, assign agents and actions, and set permissions and guardrails so every component runs under one governance model. The vendor positions this as a way to eliminate 'shadow AI' — unmanaged tools running outside IT oversight.

The platform is built around three named technologies. ODIN is a document intelligence engine that goes beyond OCR to perceive and structure complex documents natively for AI, spanning PDF, PPT, DOC, video and audio across more than twenty formats. RAG Score grades every response A/B/C with a confidence score and source cross-checking, while Devana Control performs five-layer monitoring across infrastructure, model, agent, RAG and behaviour so each LLM call is logged and each source cited. The same core engine deploys in three topologies: on-premises and multi-site clusters for banking, government and legal workloads; DIWY, a sealed, fully offline AI box suited to up to around twenty concurrent users; and a plug-and-play platform for SMBs.

Devana emphasises European data sovereignty and alignment with frameworks such as the EU AI Act, GDPR and DORA, and it follows a four-phase deployment methodology (Devana Protocol) from exploration to production. Because it is sold to enterprises and public institutions, pricing is quoted on request rather than published. The bundled browser extension lets users chat with Devana directly from any web page, and the wider product suite is reachable through a demo request.

**Pricing & Plans:** Enterprise, quoted on request. Devana does not publish a public price list; prospective customers book a strategic review or request a demo to receive deployment-based pricing.

- **Sovereign orchestration layer:** A no-code visual interface to design AI workflow pipelines, connect data sources and assign agents and actions without engineering dependency.
- **ODIN document intelligence:** Beyond-OCR extraction from PDF, PPT, DOC, video and audio across 20+ formats, with every extracted data point traceable to its origin.
- **Explainability and audit trails:** RAG Score grades responses with confidence scores and source cross-referencing, while Devana Control logs every LLM call and decision path.
- **Flexible deployment topologies:** Run on-premises or across multi-site clusters, in a sealed offline AI box, or as a plug-and-play platform for smaller teams.
- **Governance per agent:** Set tools, models, behaviour and access rights individually so every agent follows your rules and shadow AI is ruled out.

**Strengths:** Purpose-built for regulated industries with EU AI Act, GDPR and DORA alignment; Strong explainability tooling: audit trails, RAG scoring and per-decision source citation; Multiple deployment topologies, including a fully offline sealed box for air-gapped sites; No-code workflow building reduces reliance on engineering teams

**Limitations:** No public pricing; everything goes through a sales or demo process; Aimed at enterprises and institutions, so it is not a lightweight tool for individuals; The product has shifted direction over time, which can be confusing if you knew it as a research-writing assistant

## 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.
