InnerZero is a free, private AI assistant that runs entirely on your own PC.
It uses open-source AI models on your hardware, so by default nothing leaves your machine. No cloud, no account, no telemetry, no tracking. Just you and your AI.
InnerZero works fully offline. If you choose to enable cloud models, only your current message and a short context window are sent. Your memory, full history, and files are never sent. You can also bring your own API keys for providers like DeepSeek, OpenAI, Anthropic, and Google, with zero markup, going straight from your device to the provider.
The desktop app is free, with no trial and no account required. Optional paid plans cover managed cloud access, and a business licence is available for commercial use.
Available for Windows, macOS, and Linux. Built in the UK by Summers Solutions Ltd.
Your AI. Your machine. Your data.
Bear InnerZeroInnerZero's answer:
InnerZero runs entirely on your own PC. It uses open-source AI models on your hardware, so by default nothing leaves your machine. No cloud, no account, no telemetry, no tracking. You get private text and voice chat, a personal memory that remembers across sessions, 30+ built-in tools, document Q&A, and offline knowledge packs, all working without an internet connection. Cloud models are available but strictly opt-in, and even then only the current message and a short context window are sent, never your memory, history, or files. It is the privacy-first alternative to cloud assistants, built so your AI works for you, on your machine, with your data staying with you.
InnerZero's answer:
Most assistants send your prompts, documents, and personal context to overseas servers. InnerZero keeps that on your computer by default. It is free to download with no account and no trial, works fully offline, and auto-detects your hardware on first launch to pick a model that fits your machine. If you want frontier models, you can bring your own API keys with zero markup, so requests go straight from your device to the provider. It is UK-built and transparent about exactly what is sent and when. You get the privacy of local AI with the option of cloud power only when you choose it.
InnerZero's answer:
People who want a capable AI assistant without giving up their privacy. That includes privacy-conscious individuals, developers who need their code to stay on disk, writers and researchers handling sensitive material, students who want a free offline study tool, and anyone working in low-connectivity or air-gapped settings such as travel or fieldwork. It also suits small businesses and freelancers who need local AI for client-facing work under a business licence.
InnerZero's answer:
InnerZero is an early-stage product with a growing community of individual users across Windows, macOS, and Linux, plus an active Discord community.
InnerZero's answer:
InnerZero is built by Summers Solutions Ltd, a UK company founded in 2025 by Louie Summers. The starting belief was simple: AI should be personal and private. Cloud assistants made people hand over their prompts, files, and context to large overseas companies just to get useful help. InnerZero was created to flip that, putting a genuinely capable assistant on the user's own machine, with their data staying with them by default. It is developed in the UK and shipped free to download on Windows, macOS, and Linux.
InnerZero's answer:
The desktop app is built in Python with a PyWebView interface. Local AI inference runs through Ollama by default, with LM Studio as an alternative backend, both serving open-source models on the user's own hardware. Speech recognition runs locally, and offline text-to-speech is handled by Kokoro. Optional cloud access connects to providers such as DeepSeek, OpenAI, Anthropic, Google, and others. The website runs on Next.js, hosted on Vercel, with Supabase for accounts and Stripe for payments.

Bear is what you get when someone builds a notes app that respects developers. It's clean, fast, supports full Markdown, and syncs across devices. Unlike Obsidian, it doesn't require you to set up a vault structure and plugin ecosystem before you can write a single note. - Source: dev.to / 5 months ago
I kept track of bugs and ideas in Bear which, if you're in the Apple ecosystem, I highly recommend. When I stumbled on a good idea for a component that might be fun to build (sup, flip card), I'd write it down. - Source: dev.to / 11 months ago
It's odd that this blogging system is using a name also in use by a writing tool: https://bear.app/. - Source: Hacker News / 11 months ago
I got this confused with the Bear note-taking app for a minute (https://bear.app/), since it's in a closely adjacent domain and even has similar value statements. Unfortunate naming collision. - Source: Hacker News / 11 months ago
