Instead of paying for yet another model, you sign in with your existing ChatGPT, Claude, Grok, or Cursor plan (or plug in an API key), and Turnstone gives those plans persistent agents that hold onto context and memory. Because it is model agnostic, you can start a conversation on one provider and continue it on another, and the agent keeps its role and everything it has learned. The core idea is a coordinated team of agents led by a Chief of Staff. You brief that first agent on what you are working on, and it spins up specialists for each part of the job: outreach, launch writing, signup tracking, engineering, and more. Agents pass tasks to one another, each runs in its own browser tab, and scheduled jobs like a weekday morning brief run automatically and report back in your chat. Turnstone is free forever on your Mac, and what it learns stays with you in a folder you can open. An optional Turnstone Cloud add-on keeps agents working while your Mac is closed so you can message them from your phone. The app is backed by Y Combinator and is positioned as a model-agnostic alternative for people moving away from single-provider bot platforms. **Pricing & Plans:** Free forever on Mac, including persistent agents, your Chief of Staff, and app connectors — no card required. Turnstone Cloud, which keeps agents running while your Mac is closed, is $49/month after a free first month for the first 1,000 users. You supply the AI via your own ChatGPT, Claude, Grok, or Cursor subscription, API keys, or a local Ollama model. - **Bring your own AI subscription:** Sign in with ChatGPT, Claude, Grok, or Cursor, or use your own API key, and run local models through Ollama. Switch models mid-conversation without losing context. - **Agents that pass work along:** One Chief of Staff agent coordinates specialist agents — outreach, launch writer, signups, engineer — and hands work between them, returning results to your chat. - **Remembers how you work:** Persistent agents remember how you like work done and how you write in each app, from Gmail to WhatsApp, and draft replies in your voice. Nothing sends until you approve. - **Private browser per agent:** Each agent works in its own tab of the Turnstone Browser, opening sites, reading pages, and filling forms while you watch. Scheduled jobs run automatically and report back. - **Local-first data on your Mac:** Agents, chats, and memory live in a folder on your Mac, and connected data is only used to build your own memory. No model is trained on it. **Strengths:** Runs on AI subscriptions you already pay for, so no separate model costs; Model agnostic: switch providers mid-conversation without losing context; Local-first memory stored in a human-readable folder on your Mac; Free forever desktop tier with no card required **Limitations:** Mac only — Windows and Linux are not supported; The Cloud tier that runs agents while your Mac is closed costs $49/month after the first free month; Requires you to already have an AI subscription, API key, or local model setup; Browser and app connectors may not suit teams wanting fully cloud-managed workflows [Profile (Markdown)](https://openaitools.app/tool/crow.md) ## 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 [Profile (Markdown)](https://openaitools.app/tool/deepseek.md) ## Frequently Asked Questions ### How do Turnstone and DeepSeek compare in monthly traffic?
