## DeepSeek

DeepSeek (Hangzhou DeepSeek Artificial Intelligence Co., Ltd.) is a frontier AI research organization that disrupted the global LLM market by pairing open-weight transparency with breakthrough Mixture-of-Experts (MoE) and reinforcement-learning reasoning efficiency. Following the landmark releases of DeepSeek-V3 and the peer-reviewed DeepSeek-R1 reasoning model, DeepSeek introduced the DeepSeek-V4 generation in 2026—featuring a hybrid attention architecture and a native 1-million-token context window across DeepSeek-V4-Pro (1.6T total parameters, 49B active per token) and DeepSeek-V4.1-Flash (284B total parameters, 13B active per token).

Users can interact with DeepSeek in three ways: completely free through the consumer web portal (chat.deepseek.com) and mobile apps with one-click toggles for deep thinking and live web search; via DeepSeek's hosted, OpenAI-compatible developer API; or by self-hosting DeepSeek's open-weight checkpoints (including V3, R1, Prover-V2, and distilled Qwen/Llama variants) on private infrastructure. The models excel at competitive mathematics, algorithm design, repository-level software engineering, and structured data extraction, with automatic context caching on the API that slashes repeated prompt costs by over 95%.

In late 2026, DeepSeek remains the price-performance benchmark for developers and automation workflows. While the consumer chat interface remains free without a mandatory $20/month subscription tier, the developer API transitioned in late 2026 to two primary endpoints—`deepseek-flash` and `deepseek-v4-pro`—with time-of-day pricing. Off-peak API calls cost just $0.15 per million input tokens ($0.003 on cache hits) and $0.60 per million output tokens on Flash, and $0.66 input / $1.98 output on V4-Pro, making it a fraction of the cost of comparable Western frontier models.

**Pricing & Plans:** Free web and mobile chat app at chat.deepseek.com; pay-as-you-go OpenAI-compatible API with off-peak rates at $0.15/1M input ($0.003 cache hit) and $0.60/1M output for deepseek-flash (V4.1-Flash), and $0.66/1M input ($0.022 cache hit) and $1.98/1M output for deepseek-v4-pro (peak weekday UTC hours bill at 2x).

- **DeepSeek-V4 Hybrid Attention & 1M Context:** Leverages a sparse Mixture-of-Experts architecture (49B active parameters out of 1.6T on V4-Pro) to process up to 1 million tokens with minimal latency and memory overhead.
- **Transparent Chain-of-Thought Reasoning:** Pioneered by DeepSeek-R1 and integrated into V3.2 and V4 thinking modes, exposing step-by-step self-verification for complex math, logic, and code debugging.
- **Automatic Context Caching & Off-Peak API Pricing:** Drops input token costs to $0.003/1M on Flash and $0.022/1M on V4-Pro for cache hits, with 50% lower rates during off-peak UTC hours.
- **Free Consumer Web & Mobile Assistant:** Provides free access at chat.deepseek.com and on iOS/Android with document uploads, reasoning mode, and web search without paywalling core models.
- **Open-Weight Ecosystem & Self-Hosting Freedom:** Offers open weights for DeepSeek-V3, R1, Distill variants, and Prover models on Hugging Face and GitHub so enterprises can deploy within air-gapped environments.

**Strengths:** Completely free consumer web and mobile app with deep reasoning and web search included; Ultra-low API token rates ($0.15/$0.60 on Flash, $0.66/$1.98 on V4-Pro off-peak) with up to 98% savings on cached inputs; Drop-in OpenAI API compatibility makes switching or routing between models effortless; Strong open-weight lineage allows teams to self-host or fine-tune models without vendor lock-in

**Limitations:** Hosted API and web app store data on servers in China, prompting compliance restrictions for some Western enterprises and government agencies; Peak-hour API pricing (01:00–04:00 and 06:00–10:00 UTC on weekdays) doubles per-token costs compared to off-peak rates; Lacks native voice mode, video generation, and productivity suite integrations offered by ChatGPT and Google Gemini

## Linguix

Linguix is a writing assistant built around a browser extension and web editor. Once installed, it checks your writing on Gmail, Google Docs, OpenAI tools, Canva, and millions of other websites, flagging spelling and grammar mistakes as you type and offering AI-driven suggestions for punctuation, clarity, and style. It supports multilingual proofreading across English, French, German, Spanish, Portuguese, Italian, and Polish, detecting the language and adjusting suggestions automatically.

Beyond basic correction, Linguix includes an AI rewriter for shortening, expanding, or restating sentences, and a Content Score that rates text on factors like sentence length, vocabulary complexity, and passive-voice usage — useful for benchmarking drafts produced by tools such as ChatGPT. Intelligent shortcuts let you expand one-word commands like "//intro" into full templates, cutting down repetitive typing on email and social platforms.

On the business side, Linguix adds Style Guides to enforce consistent, professional, and inclusive company language, plus Team Management with performance stats, error counts, readability scores, and email reports for every member. The platform is offered by Textly Inc., serves a large user base across Chrome, Edge, and Figma, and publishes a separate AI Content Detector and AI Humanizer in its tool lineup.

**Pricing & Plans:** Freemium. A free tier covers core grammar and spelling checking with the browser extension, while individual and business plans unlock AI rewriting, style guides, team management, and API access. Specific prices are listed on Linguix's pricing page.

- **Multilingual grammar and spell check:** Detects and corrects writing issues in English, French, German, Spanish, Portuguese, Italian, and Polish across any site.
- **AI rewriter and Content Score:** Rewrite, shorten, or expand sentences and score text quality based on complexity, sentence length, and passive voice.
- **Style guides and shortcuts:** Enforce company terminology and expand short commands into reusable templates to speed up repetitive writing.
- **Team management and reporting:** Track error counts, readability, and writing activity per team member with periodic email reports.
- **Works where you type:** Browser extension and web editor cover Gmail, Google Docs, Canva, OpenAI, Figma, and millions of other sites.

**Strengths:** Works inside the apps you already use rather than a separate editor; Supports seven languages for multilingual teams; Business tier adds style guides and member-level analytics; Free plan is genuinely usable for everyday proofreading

**Limitations:** Best features such as rewriting and team tools sit behind paid plans; Suggestion quality can still require human judgment on nuanced copy; Team analytics may feel heavy-handed in some organizations
