## 1Stroke

1Stroke takes a narrow, practical view of AI writing: instead of opening a separate chatbot and pasting text back and forth, it puts the assistant where your words already live. Its tagline sums up the pitch — "the fastest way to craft meaningful replies anywhere on the web" — and its two core actions are Reply with AI and Rephrase with AI. Because it adapts to your own words and tone, the output is intended to sound like you rather than like a generic AI voice.

Support for "all websites" is the key differentiator. Many reply assistants are tied to a single inbox or social network; 1Stroke aims to work on whatever page you happen to be on, which covers email, social comments, review responses, and support threads in one extension. Setup is quick: install the extension, sign in through the app subdomain, and the assistant appears alongside the text fields you already use.

Pricing is deliberately simple and posted publicly on the site. The Free tier includes Reply with AI and Rephrase with AI across all supported websites but with limited power. Premium is listed at $7.50 per month billed monthly and adds customization, full power, and customer support. A Teams plan carries a custom annual price with membership and permission management, personalized customization help, training, and 7/7 support. The company also promotes a seven-day trial framed as "try now, pay later", so you can evaluate draft quality in your own workflow before subscribing.

**Pricing & Plans:** Free tier with limited power (reply and rephrase on all supported sites); Premium at $7.50/month billed monthly with customization, full power, and support; custom Teams plan billed annually with admin controls and 7/7 support. A 7-day free trial is advertised.

- **Reply with AI on any website:** Select any message, comment, or email on a web page and let 1Stroke generate a ready-to-send reply that fits the surrounding conversation.
- **Rephrase and refine with AI:** Rewrite a draft to change wording, shorten it, or shift the tone without leaving the page you are working in.
- **Context-aware, tone-matching drafts:** 1Stroke reads the surrounding context so suggestions match the message thread instead of producing generic templates.
- **Free tier plus Premium upgrade:** The free tier covers reply and rephrase on all supported sites with usage limits, while Premium unlocks full power and customization.
- **Teams and admin controls:** Team admins can manage membership, permissions, and onboarding, with 7/7 customer support on the annual plan.

**Strengths:** Works on any website from the page itself, avoiding copy-paste into a separate chatbot; Two focused jobs — reply and rephrase — that cover most day-to-day writing needs; Free tier is genuinely usable for light reply and rephrase work; Clear, publicly listed pricing with a low-cost $7.50/month Premium tier

**Limitations:** Premium tier is a recurring subscription and the free tier caps usage ("limited power"); Draft quality still needs a quick human review before sending in sensitive contexts; Requires installing a browser extension, so it does not cover mobile app or desktop-app chats; Customization options are simpler than some dedicated brand-voice writing suites

## 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
