## Dechecker

Dechecker centers on a paste-and-check workflow: you drop in up to roughly 1,000 words, or upload a document, and the detector returns an overall AI probability plus a sentence-level breakdown showing which passages triggered the model. Alongside the core check you can stack optional passes such as a plagiarism scan, a grammar pass and a fact-check, and the platform also exposes sibling tools for AI code detection, AI image detection, transcription, summarization and essay writing.

Its stated positioning is accuracy with few false positives, achieved by scoring sentence structure, phrasing rhythm and transitions rather than looking for fixed keyword lists. When something is flagged, the tool explains why that sentence reads as machine-generated and offers one-click rewriting so writers can smooth the pattern out instead of rewriting from scratch. Bulk document upload, downloadable reports and a saved history are provided for people checking more than one file.

Accessibility is the main selling point: the checker is free, needs no account for a basic run, and shows a "100 free credits" offer alongside paid options for heavier usage. Text is described as processed without being stored, which matters for students and professionals checking unpublished coursework or client material. The site is translated into several languages and claims more than a million users.

**Pricing & Plans:** Dechecker advertises a free tier with no registration required for basic AI checks, and the site surfaces a "claim your 100 credits" offer for signed-in users. Beyond that, plan details and paid tiers vary, so check the pricing page for current limits and per-word or per-credit bundles.

- **Sentence-level AI detection:** The checker returns an overall AI probability plus a per-sentence breakdown, so you can see exactly which lines read as machine-written instead of guessing from a single number.
- **Built-in humanizing rewrites:** Flagged sentences come with an explanation of what triggered the flag and one-click rewrite suggestions that reduce tell-tale AI patterns while keeping your meaning.
- **Add-on verification passes:** Optional plagiarism, grammar and fact-check modules can be layered onto the same text, turning a single submission into a broader originality and quality review.
- **Document upload and bulk scanning:** Paste text directly or upload files, and scan multiple documents in one pass when you are reviewing a stack of papers or drafts.
- **Report history and downloads:** Detection results are saved to a library and can be exported, which helps when you need a record of checks over time or proof of a review.
- **Extra detectors for code and images:** Separate tools detect AI-written code and AI-generated images, covering project types beyond plain essays and articles.

**Strengths:** Core AI check is free and requires no signup for a quick run; Sentence-level explanations make results actionable rather than just a score; Extra plagiarism, grammar and fact-check modules cover more ground in one place; Document upload, bulk scanning and saved reports suit multi-file workflows

**Limitations:** The free allowance is credit and word limited, so heavy use runs into paid tiers; AI detectors in general can still misfire on heavily edited or non-native human writing; Detection accuracy depends on language and text length, so very short passages are less reliable

## 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
