## PERSYS

PERSYS is dedicated hardware rather than an app or a cloud subscription. It is positioned as a complement to your laptop and phone, not a replacement: a box that sits at home and acts like your own personal cloud, holding files and running AI inference locally.

Because inference happens on the device, conversations with the assistant are not sent to external servers, and the system stays usable without an internet connection. The software stack is open source for transparency, and the device ships with AI-native applications built for the hardware: Private Chat, Deep Search, Smart Notes, Document Library, Private Gallery and Media Player.

The specification is deliberately simple. Two storage tiers are offered, 1 TB and 2 TB, with 8 GB or 16 GB of memory respectively, dual WiFi and 27 W power draw in a matte white enclosure with a stand included. PERSYS is sold directly by AdulisAI, Inc. with support documentation, a GitHub presence and community links.

**Pricing & Plans:** Hardware purchase, no subscription mentioned. The 1 TB model is listed at $300 and the 2 TB model at $330, with the stand included. Prices are as shown on the vendor site and may change.

- **On-device AI inference:** Models run locally, so chats and prompts are processed on the device rather than in a remote data centre.
- **Works without internet:** Chat, search, notes and the document library remain accessible with no connection, making the device useful offline.
- **Large local storage:** Choose 1 TB or 2 TB of solid-state storage for photos, videos and documents, all kept inside the device.
- **AI-native apps:** Private Chat, Deep Search, Smart Notes, Document Library, Private Gallery and Media Player are built for the hardware from the ground up.
- **Open source software:** The stack is published openly so users and researchers can verify what the device actually does with their data.

**Strengths:** Conversations and files never leave your hardware; Fully usable offline, including AI chat and search; Open source software aids transparency and trust; Straightforward pricing with no subscription required

**Limitations:** On-device models are typically less capable than the largest cloud models; You buy dedicated hardware upfront, a bigger commitment than an app; Documentation pages were not reachable at the time of the check

## Vellum

Vellum is a personal AI assistant rather than a chat box. The core idea is ownership: your assistant runs locally on your own machine by default, or in a dedicated cloud container if you prefer Vellum Cloud, and it is yours to shape. You configure how it talks, what it can touch and which models it uses, choosing between OpenAI, Anthropic, Gemini or open-weight models via Ollama. The codebase is open-source, so the privacy claims can be inspected rather than merely trusted.

What separates it from a general-purpose chatbot is memory and autonomy. Vellum's custom memory system tracks you, your people, your preferences and your ongoing work across conversations, so context does not evaporate when a session ends. With built-in skills for Google Workspace, Slack, Notion and your filesystem, plus community and custom plugins, the assistant can send emails, manage calendars, browse the web, generate slides, write code, run deep research, monitor sites and repeat background tasks on a schedule. Because it acts rather than only answers, Vellum ships a fine-grained permission system: actions with real consequences require approval until you mark them trusted.

Availability is broad by design. It is native on Mac and reachable through iOS, Android, a web app, voice, email, Telegram, Slack and the terminal, with the same memory, tasks and schedules on every surface. Vellum is free to download and run locally; cloud subscriptions start at $30/month (Mighty), $100/month (Super) and $200/month (Ultra) with dedicated compute, storage and bundled credits. Note that the company has announced the Personal Assistant Platform is shutting down by December 13, 2026, so verify current availability and export options before committing.

**Pricing & Plans:** Free to download and run locally. Vellum Cloud subscriptions start at $30/month (Mighty), $100/month (Super) and $200/month (Ultra), each with dedicated compute, storage and bundled credits. Credits are consumed by actions. The site also notes the Personal Assistant Platform is shutting down by December 13, 2026, with instructions to download your assistant.

- **Long-term personal memory:** A custom-built memory system that retains you, your people, preferences and work across every conversation, rather than resetting each session.
- **Skills and tool integrations:** Connect Google Workspace, Slack, Notion, your filesystem and community plugins so the assistant can send emails, manage calendars, browse, create slides and run research.
- **Fine-grained permissions:** Set permissions so sensitive actions like emailing new contacts or modifying key files require approval until you mark them trusted.
- **Model choice:** Switch between OpenAI, Anthropic, Gemini or open-weight models via Ollama at any time, keeping you free of a single vendor lock-in.
- **Local-first privacy:** Your assistant runs locally by default with open-source code you can inspect; Vellum Cloud offers an isolated container provisioned just for you.
- **Available everywhere:** Native on Mac and available on iOS, Android, web, voice, email, Telegram, Slack and terminal, all sharing the same identity, memory and schedules.

**Strengths:** Runs locally by default with open-source code you can audit; Genuine long-term memory that persists across every conversation; Model-agnostic: OpenAI, Anthropic, Gemini or local open weights via Ollama; Takes real actions across email, calendar, files and connected tools

**Limitations:** The homepage banner states the Personal Assistant Platform is shutting down by December 13, 2026; Proprietary cloud tiers at $30–$200 per month, and credit-based actions can add cost; High-stakes actions require approval prompts until you mark them trusted, adding friction early on; Mac-first native experience, so non-Apple users depend on web and chat surfaces
