## 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

## RewriteBar

RewriteBar solves a very practical problem for Mac users: most writing assistants live in their own editor or browser tab, while real writing happens everywhere — Slack threads, email clients, Google Docs, Notion, Word, WhatsApp and code editors. RewriteBar instead sits at the system level. It grabs your current selection, sends it to a language model with the action you picked, and pastes the result straight back over the original text, so you never leave the app you are working in.

Out of the box it ships with a library of ready-made actions: grammar and spelling fixes that understand full-sentence context, rewriting for clarity, simplification, tone adjustment, humanizing AI-sounding text, summarising to bullet points, fixing broken JSON, converting to title case, turning formal German or French into the informal register, and translation across 500+ languages. On top of those presets you can build your own commands, insert variables, and chain several actions into one workflow — expand, emoji-fy, translate and summarise in a single pass. A side-by-side diff view lets you check exactly what changed before you accept it.

Flexibility is the other selling point. You can bring your own API key from OpenAI, Anthropic, Google, Groq, Mistral, DeepSeek, OpenRouter and dozens more; subscribe to the RewriteBar Gateway to get access to 70 models without managing keys; or run everything through a local model with Ollama, LM Studio or Apple Intelligence for maximum privacy. The app is only around 25 MB, is natively built for macOS, integrates with PopClip, and never stores your text on RewriteBar's servers.

**Pricing & Plans:** Freemium with a free trial, then one-time licences. Try it free with 35,000 credits and no credit card; Standard is $29 one-time (1 device, 35,000 credits, BYOK and local models); Pro is $59 one-time (3 devices, 1 year of RewriteBar Gateway with 3 million monthly credits). Extra devices cost $19 one-time, and the RewriteBar Gateway can be bought separately for $40 per year. Refunds available within 14 days.

- **Works in any application:** RewriteBar captures the selected text system-wide and pastes the improved version back, so it functions in Chrome, Google Docs, Word, Slack, Notion, VS Code, email clients and more.
- **Preset and custom AI actions:** Use built-in commands such as fix grammar, simplify, humanize, summarise, title case, fix JSON, create ASCII art or translate, or author your own commands with variables and prompt libraries.
- **Chain actions into workflows:** Combine several actions to transform text step by step — for example expand, add emojis, translate and rewrite a title in one flow.
- **Cloud or fully local models:** Bring your own API key from major providers, use the RewriteBar Gateway, or keep everything on-device with Ollama, LM Studio, oMLX or Apple Intelligence.
- **Diff view and shortcut-driven flow:** Compare original and rewritten text line by line or word by word, and trigger everything from keyboard shortcuts or PopClip integration.

**Strengths:** Genuinely app-agnostic thanks to system-level text capture; One-time licence options with no mandatory subscription; Strong privacy story with local model support and no server-side text storage; Very small footprint (~25 MB) with native macOS performance

**Limitations:** macOS only, with no Windows or Linux version; Some actions require configuring your own API key, which adds setup work and separate provider costs; Advanced workflows and the 70-model gateway are gated behind the Pro or Gateway plans
