## ailight

ailight is a desktop AI command bar for macOS and Windows built around a single idea: stop copying text into chatbots and bring AI to the work you are already doing. You highlight text or take a screenshot inside whatever app is open — an email client, spreadsheet, browser, note app, terminal or IDE — and ailight applies an AI action to that selection in place.

The product ships with a set of practical slash commands that map to everyday chores. /formal rewrites a draft professionally, /fix corrects grammar, /list converts prose into bullets, /simple and ?summary condense dense material, and ?translate moves it into your native language. For analytical work, /insights interprets a screenshot of a chart or dashboard, /csv pulls structured data out of an image, /explain decodes a cryptic error message and /to-json structures messy data.

The real differentiator is custom actions. You define how a given kind of text or image input should be transformed, save the action, and reuse it with one click, gradually building a personal library of AI-powered tools. The paid ailight ultimate tier adds backup and sync of those actions across all your Windows and macOS computers, so your setup follows you between machines. The base experience is usable for free, with a trial path to the subscription.

**Pricing & Plans:** ailight uses a freemium model. The core highlight-and-transform experience and built-in commands are available for free, with a paid ailight ultimate tier that adds backup and cross-device sync of custom actions across your Windows and macOS machines. A trial lets you evaluate the paid tier.

- **Transform anything on screen:** Highlight text or capture a screenshot anywhere on your desktop and run an AI action on it without switching apps or copying into a chatbot.
- **Custom actions:** Build your own AI actions for the transformations you repeat, then save and trigger them with a click to grow a personal library of tools.
- **Slash commands for common tasks:** Ready-made slash commands such as /formal, /fix, /list, /insights, /csv, /explain, /to-json and /simple cover common writing, data and coding tasks.
- **Text and image understanding:** Point ailight at a dashboard, chart or error screenshot and get explanations, insights or extracted data without manual entry.
- **Backup and sync across devices:** Create an action once and sync it across your Windows and macOS machines with ailight ultimate.

**Strengths:** Works inside every desktop app without context switching; Custom actions let you encode your own repeatable workflows; Handles both text selections and screenshots; Both macOS and Windows supported

**Limitations:** Limited to macOS and Windows — no Linux or mobile app; Free tier does not include action backup and cross-device sync; Requires an internet-connected LLM, so offline use is not possible; Very lightweight homepage means fewer published details about model choices and data handling

## 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
