## dioptify

dioptify describes its work simply: software that survives everyday operations, and it keeps running the systems after delivery. The studio, led by managing director Kevin Peivareh, is based in the Hannover region and hosts on ISO 27001-certified servers in Nuremberg. Its commercial register entry lists the purpose as software and IT services applying artificial intelligence, and it is set up to work with both companies and public-sector clients, including through a dynamic procurement system.

Three kinds of work dominate. First, operational software for teams who work outdoors — the crewwerk app handles clock-in at the yard, routes in the vehicle, departure checks, photos per job site and hours for the office, and keeps working offline until the device reconnects. Second, AI agents: a telephone assistant that identifies itself as AI, answers follow-up questions and books appointments into the calendar, plus an order-intake agent that turns informal phone or email orders into delivery notes and asks when something is unclear. Third, taking over inherited systems, securing them and making them reproducibly deployable before anything is changed.

Alongside client work, dioptify runs its own products. The anonymizer blurs faces, license plates and personal data in photos and documents on your own hardware and removes metadata, available as a web tool and an iPhone app. deutschlandheiratet.de is a wedding portal with provider comparison, a planning assistant and a guest-photo app. The ai-app-cloner code agent is published as open source under the MIT license. The workflow is transparent: enquiry, clarification and written quote, an early link to the current build with staged approvals, then testing against test cases before live operation — and support afterwards.

**Pricing & Plans:** Pricing is quote-based rather than listed publicly. The site directs visitors to a services page for prices and details and to a contact form to request a project, with a reply promised within one working day. Because the studio also runs its own products — the anonymizer web tool and iPhone app, the wedding portal and the open-source ai-app-cloner agent — some pieces can be used before commissioning any paid work.

- **Field-service operations apps:** Clock-in, routes, photo proof per job site and hours for the office, in an app that keeps working without reception and syncs once the device is back online.
- **AI agents for orders and calls:** Voice and email agents that take orders, calls and enquiries and hand them to your systems in a usable form, are tested against test cases before going live, and ask instead of guessing when something is ambiguous.
- **Custom apps and integrations:** Web and iPhone/Android applications, interfaces to ERP systems over XML and EDIFACT, on-device image processing and compliant e-invoicing such as XRechnung per EN 16931.
- **Legacy system takeover:** Legacy applications inherited without handover or documentation are secured and made reproducibly deployable first, so changes happen afterwards without outage windows.
- **Web presence and content:** Websites, landing pages, SEO, design and short videos for Instagram, TikTok and LinkedIn, produced for the same clients that use the engineering side.

**Strengths:** Build-and-operate model: the same team that ships your software keeps running it; Offline-first field apps and tested AI agents designed for real operational conditions; On-device and Germany-hosted processing with ISO 27001-certified infrastructure; Clear process with staged approvals and test cases before anything goes live

**Limitations:** Not a self-serve product: everything starts with a project enquiry and a written quote, so there is no signup-and-go free tier; Operated mainly in German and focused on the Hannover region, which limits fit for international teams; Image, video and style-transfer processing from the old cloud suite is no longer the core offering; No public price list — budgeting requires contacting the team first

## 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.
