Tempreon is a personal memory layer for your AI tools, connected over MCP. Your knowledge, preferences, and decisions travel across Claude, ChatGPT, Cursor, and any MCP-capable client โ captured once, available everywhere. It learns how you actually work instead of just storing what you said.
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.
Tempreon
InnerZeroTempreon's answer
Tempreon is built for the person, not the app. Most memory products are developer APIs for adding memory to a single product; Tempreon is a memory layer you own that travels with you across every AI tool you use โ Claude, ChatGPT, Cursor, anything MCP-capable.
InnerZero'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.
Tempreon's answer
Most alternatives in this space are memory infrastructure for developers building their own AI apps. If you're the person using several AI tools every day, that's not your problem โ your problem is re-explaining yourself to each of them and losing everything when you switch.
The choice is really about who the memory is for. Ours is for 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.
Tempreon's answer
Individuals who live in AI tools all day: operators, consultants, founders, sales professionals, and knowledge workers who use more than one assistant and are tired of being a stranger to each of them.
If you've ever pasted the same context into Claude and ChatGPT in the same week โ you're the audience.
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.
Tempreon's answer
Tempreon started with a simple observation: AI models keep changing, but the thing that makes them useful to you โ your context, your preferences, your judgment โ gets rebuilt from scratch inside every tool, and lost every time you move.
We built the layer that fixes that: person-owned memory served over the open Model Context Protocol, so it works across assistants instead of belonging to one. Along the way we open-sourced the pieces that are useful to everyone regardless of whether they use Tempreon โ like memhaul, our MIT-licensed CLI for turning ChatGPT and Claude data exports into files you own.
The through-line is custody: the model is temporary, your memory shouldn't be.
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.
Tempreon's answer
The protocol choice is the product decision: build on the open standard, and your memory works everywhere the standard does.
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.
