“I want a powerful, free assistant to reason and write, with no subscription”

The curious, students and tinkerers comfortable with a simple interface mainly in English and Chinese — and not for sensitive documents.

Recommended agent: DeepSeek

💰 $0 for the chat (chat.deepseek.com and apps). No consumer paid plan; only the developer API is billed, per token. Level: Intermediate 🌍 China Free chat with Instant and Expert modes and a very long context (1M tokens announced for the V4 generation); free-plan limits not published. The models are open (downloadable weights): also usable locally, for example via our Ollama profile

A free and surprisingly powerful assistant (chat.deepseek.com and apps) to reason, write and explain step by step: Expert mode shows its reasoning and the announced context reaches 1M tokens. Its models are open and downloadable — but the online service is hosted in China, which imposes a strict guardrail on what you paste into it.

How it works

Trigger: You ask a question or paste a text to work on — reasons in Expert mode, summarizes, translates, restructures and explains step by step, and you get a detailed explanation, a summary or a draft, without paying for a subscription.

Step-by-step setup

Open chat.deepseek.com or the DeepSeek app and create a free account.
Use Expert mode for complex questions and read the reasoning.
Paste long texts to summarize or restructure — never sensitive documents.
To work without sending data, install an open model locally via our Ollama profile.

⚠️ Guardrails: DeepSeek's official privacy policy states that data is collected, processed and stored in the People's Republic of China, and can be used to improve the models: put no personal, professional or confidential document there. For sensitive material, prefer local execution.

Its particular angle

Like every general-purpose assistant, it can chat, write, summarize, translate and help with code. What sets it apart: it's free and very strong at reasoning — with a serious guardrail: your data is hosted in China.
