## 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

## pdf.net

pdf.net positions itself as a single browser tab that replaces a stack of desktop PDF utilities. Upload a file — or pull one in from Google Drive — and you can edit text directly on the page, drop in images, sign, annotate, redact, watermark, protect with a password, merge, split, rotate, reorder or Bates-number the document without installing anything. A converter section spans roughly thirty pairings, moving between PDF and Word, Excel, PowerPoint, CSV, JPG, PNG, HEIC, EPUB, Markdown and plain text, including niche jobs like pulling bank statements into spreadsheets.

Alongside the classic utilities, the platform exposes a compact AI layer. Chat with PDF lets you ask natural-language questions about an uploaded document, the PDF Summarizer condenses long files into key points, Generate PDF turns a written description into a formatted document, and AI Form Filler reads an existing document to populate a form's fields. These AI options are the reason the product also appears in AI writing and summarizer directories, though the bulk of the value is still conventional PDF tooling.

It is an independent product rather than an official Adobe or Google offering, and the site states that data is encrypted with AES-256 at rest and TLS in transit on Google Cloud, with files retained in your account until you delete them. The interface is mobile-friendly and available in several languages.

**Pricing & Plans:** Freemium with a subscription for output. Uploading, editing, signing and rearranging a PDF can be done without an account, but downloading a finished file or running a conversion requires a pdf.net subscription. Exact plan prices are shown on the site's own pricing page.

- **Full PDF editing toolkit:** Edit text, fonts, sizes and colours directly in the document, insert images, add page numbers, watermarks and Bates numbering, rotate, extract or rearrange pages, and split or merge files.
- **Broad format conversion:** Convert between PDF and Word, Excel, PowerPoint, CSV, JPG, PNG, HEIC, EPUB, Markdown and text, including bank-statement-to-spreadsheet and PDF comparison workflows.
- **Signing, security and redaction:** Type, draw or upload a signature, request signatures by email, add password protection, black out sensitive content and make flat or scanned forms fillable.
- **AI document tools:** Chat with a PDF to ask questions about its contents, summarize a long document into key points, generate a formatted PDF from a description, or have AI populate a form automatically.
- **Privacy and cross-platform access:** Files are encrypted with AES-256 at rest and TLS in transit on Google Cloud, and the editor works the same on desktop, tablet and phone with Google Drive import.

**Strengths:** Very wide feature set covering editing, conversion, signing and security in one browser tab; Editing, signing and page management can be tried without creating an account; AI features such as chat, summarization and form filling sit alongside practical PDF utilities; Responsive interface with Google Drive import and support for unusual input formats like HEIC and Markdown

**Limitations:** Downloading or converting a file requires a paid subscription, so free use is limited to in-browser editing; Large files and longer conversions depend on server processing time; The AI toolset is smaller than the number of classic PDF utilities, so it is not a dedicated AI document assistant
