## 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.

## Seedance 2.5 API

Seedance 2.5 API positions itself as a practical working site for engineers and product teams building video generation features. Rather than a simple landing page, it mixes a prompt-and-example gallery, step-by-step workflow guidance, an API quickstart with Python and JavaScript snippets, and a detailed pricing reference arranged by resolution and clip length. The latest generation, Seedance 2.5, is documented as a pending release — the site openly states that pricing and model access are not yet open and advises teams not to hard-code a model ID in production until routing is confirmed.

The currently usable baseline is Seedance 2.0, which the site routes through EvoLink and prices per generated video (for example $0.46 for a 480p 5-second clip up to $15.18 for a 4K 15-second clip). The workflow is deliberately simple: register and top up, send a RESTful generation request, then poll a task ID or receive a webhook when the video is ready. Commercial usage rights are included and no subscription is required.

The comparison tables contrast Seedance 2.5 against Seedance 2.0, Kling 3.0 and Veo 3.1 on resolution, duration, audio support and input modalities, giving teams a starting point for cost modelling before they commit engineering time. Because the site aggregates speculation and announced information about an unreleased model, its forward-looking specs should be treated as reference only, not a guarantee.

**Pricing & Plans:** Pay-as-you-go with no subscription required; Seedance 2.0 is billed per generated video (e.g. $0.46 for 480p/5s up to $15.18 for 4K/15s), while Seedance 2.5 pricing is listed as coming soon. Enterprise SLA and volume pricing are available on request.

- **RESTful video generation API:** Three-step flow — POST a prompt, poll the returned task ID, then download the finished video URL — with ready-to-copy Python and JavaScript snippets for text-to-video, image-to-video and reference-to-video.
- **Transparent cost reference:** Per-video and per-second pricing broken down by resolution and duration for Seedance 2.0, alongside public reference prices for Kling 3.0 and Veo 3.1 so teams can budget before building.
- **Seedance 2.5 vs 2.0 comparison:** A capability-by-capability breakdown covering resolution, clip length, reference assets, local editing, multilingual speech and physics simulation, with clear flags on what is announced versus confirmed.
- **Prompt and example gallery:** Real outputs generated through the API with the prompts that produced them, covering documentary, martial-arts restyle, VFX edit and fashion-film briefs.
- **Production onboarding guidance:** Documentation on API access status, model IDs, webhook callbacks and the evaluation criteria teams should test before making a new model their default route.

**Strengths:** Clear, per-video pricing math for Seedance 2.0 that makes production budgeting straightforward; Honest status reporting — the site explicitly labels Seedance 2.5 specs as announced/pending rather than confirmed; Ready-to-run Python and JavaScript API snippets lower integration time; Comparison tables put Seedance, Kling and Veo cost and capability side by side in one place

**Limitations:** Seedance 2.5 pricing and model access are not yet available, so the headline promise is still forward-looking; It is an independent third-party hub, not an official ByteDance product page, so specs should be verified against primary sources; Some competitor pricing on the comparison page is public reference data that can drift out of date
