## 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.

## WriteMyPRD

WriteMyPRD solves a very specific, very common frustration: staring at a blank PRD template. Instead of starting from an empty document, you answer a short form — product name, feature name, a basic overview, a feature list, and any qualitative user feedback you have — and the bot returns a first draft of a Product Requirements Document. It is deliberately built as a starting point, not a finished artifact; the tool itself warns that less input is better, because the goal is to get you moving rather than to over-optimize the prompt.

The generator runs on ChatGPT and was created by the teams behind Olvy (an AI feedback-analysis product) and TheProductFolks, a product-management community. Beyond the web form, there is a Slack bot you can add to your workspace: it introduces itself as your PRD writing assistant, asks what your product does, and helps you kickstart the document inside Slack so the draft lands where your team already talks.

The site also curates external resources for writing better PRDs — step-by-step guides and template collections from Razorpay, Lenny's Newsletter, and Aha! — and links to ProductHooman, a podcast for product builders produced by Olvy. WriteMyPRD is a free, single-purpose utility rather than a full requirements-management platform: there is no database of documents, no stakeholder review workflow, and no version history. You generate a draft, copy it, and continue writing in your own tool.

**Pricing & Plans:** Free to use, with no credit card required. The site lists no paid tiers; WriteMyPRD is a free utility offered by the teams at Olvy and TheProductFolks, with an optional account login and a Slack bot.

- **Form-to-Draft PRD Generation:** Enter your product name, feature name, overview, feature list, and user feedback, then click Generate My PRD to receive a structured draft written by ChatGPT.
- **ChatGPT-Powered Writing:** The generator is built on ChatGPT, so the draft follows recognizable PRD structure and is phrased as editable product-manager prose rather than raw bullet fragments.
- **Slack Bot Assistant:** Add the WriteMyPRD bot to Slack and it will ask what your product does, then help you start the PRD right inside your team's workspace.
- **Sample Requirement Demo:** A 'Try with a sample requirement' button fills the form with an example so you can see the output quality before investing effort in your own input.
- **Curated PRD Resource Library:** Hand-picked guides and template collections from Razorpay, Lenny's Newsletter, and Aha! are linked to help you improve the draft once it is generated.

**Strengths:** Completely free with no signup wall before you can try it; Removes the blank-page barrier in seconds; Slack bot lets you draft inside the tool your team already uses; Companion resource links help you improve the draft rather than leaving you stranded

**Limitations:** Output is only a starting draft; it still needs substantial human editing; Single-purpose utility with no saved document library, review flow, or version history; Quality depends entirely on how clearly you describe the product in a short form
