## Cordial

Cordial is a French-language AI proofreading tool, delivered as a Chrome extension so it follows you across the web. As you type into websites, webmail, chat windows and content tools, its correction engine analyses each sentence and marks problems with clear, colour-coded underlines: red for spelling and blue for grammar, syntax and typography.

What sets Cordial apart from a simple spell checker is its focus on style. It flags not only misspellings but also agreement mistakes, incorrect tenses, redundant commas and unfortunate pleonasms, aiming to help you write more polished French rather than merely typo-free French. The publisher advertises a correction rate of around 90%.

The extension is published by the team behind cordial.fr and ties into a wider ecosystem. Cordial Analytics gives you a personal report of your most frequent errors, your average writing quality and your progress over time, while built-in dictionaries and over 200 pages of grammar guidance make the tool a learning aid as well as a proofreader. It integrates with everyday tools such as Gmail, Outlook, WordPress, Jira and Salesforce.

**Pricing & Plans:** The Cordial Chrome extension is free to add and use. Cordial is developed by the French company behind the cordial.fr proofreading software; pricing for the full Cordial product is available from the vendor.

- **AI correction engine:** The correction engine runs on an AI model that highlights spelling in red and grammar, syntax and typography in blue, using explicit underlining as you write.
- **Style and syntax checks:** Beyond typos, Cordial flags style problems such as agreement errors, wrong tenses, redundant commas and awkward pleonasms.
- **Cordial Analytics dashboard:** A personalized dashboard reveals your most frequent mistakes, average writing quality and progress over a period.
- **Works across your tools:** Cordial plugs into the tools you already use, including Gmail, Outlook, WordPress, Jira and Salesforce, so you can correct without switching apps.
- **Language resources built in:** Direct access to French dictionaries and more than 200 pages covering grammar categories, agreements and other rules.

**Strengths:** Focused, high-quality French correction rather than generic multilingual checking; Catches style and syntax issues, not just spelling; Analytics dashboard makes your recurring mistakes visible; Runs inside the apps you already use, including Gmail, Outlook, WordPress, Jira and Salesforce

**Limitations:** Limited to French, so it is not useful for English or other language writing; The most advanced features sit within the wider paid Cordial ecosystem; Browser extension only — no standalone desktop or mobile typing app

## 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
