## Clevermail

Clevermail is a browser extension distributed through the Chrome Web Store that layers an AI writing layer on top of Gmail. Instead of starting every message from a blank compose window, you give the assistant a brief instruction and some context about your business or the recipient, and it returns a complete, professionally worded email draft you can review, tweak and send.

The extension is aimed at people who live in their inbox — sales teams, founders, freelancers, recruiters and support staff — and who lose time finding the right phrasing for routine messages. Because the drafts are generated from the context you supply, the aim is output that reads as if you wrote it rather than as generic template text. Multilingual support means you can produce a message in a language other than the one you think in, which is useful for international clients and partners.

Clevermail installs like any other Chrome extension and works inside the Gmail interface, so the typical workflow of reading a thread, replying and sending stays uninterrupted. The free tier covers light everyday use, with paid options for people who write a high volume of email. The extension is published by the team behind clevermail.co, has a small but positive user rating on the Chrome Web Store, and requires permissions to handle personally identifiable information and personal communications, which is expected for an email assistant — check the developer's privacy policy if data handling matters for your organisation.

**Pricing & Plans:** Freemium. A free tier covers everyday email drafting, with paid plans unlocking higher usage limits and advanced features. Check the Chrome Web Store listing or clevermail.co for current plan details and prices.

- **AI email drafting in Gmail:** Give a short instruction plus context about your business or recipient and receive a complete, professionally phrased email draft ready to review and send, without leaving the Gmail compose window.
- **Personalized, on-tone output:** Drafts are generated from the context and inputs you provide, so the result targets your actual situation and relationship rather than producing generic boilerplate copy.
- **Multilingual support:** Compose and generate messages in languages beyond your native one, which helps when corresponding with international clients, partners or colleagues.
- **Send directly from the extension:** Review the generated draft and send it from within the extension flow, keeping the read-reply-send loop inside Gmail instead of switching between apps.
- **Lightweight browser integration:** Installs as a standard Chrome extension with a small footprint, so it adds AI assistance to the Gmail interface you already use without a separate dashboard.

**Strengths:** Generates complete, professional Gmail drafts from a short prompt and context; Works inside Gmail, so there is no separate app or workflow to learn; Multilingual output is useful for international correspondence; Free tier lets you test it on everyday email before paying

**Limitations:** Requires access to personal communications and personal information, which some organisations will not permit; Only useful if you already work in Gmail on Chrome; Small user base and a single developer listing, so long-term support is less proven

## 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
