Trust by default
Most assistants treat your data like fuel. ZHAR treats it like a private conversation. Your conversations are encrypted with AES-256 on your device — we literally cannot read them.
Built in Berlin. Privacy first.
ZHAR is a personal AI that remembers your conversations for years, builds new skills from your requests, and stores everything encrypted on your device — never on our servers. Currently in private beta.
Built for people who want useful intelligence without surveillance.
Most assistants treat your data like fuel. ZHAR treats it like a private conversation. Your conversations are encrypted with AES-256 on your device — we literally cannot read them.
ZHAR remembers preferences, projects, and patterns so you do not repeat yourself every week. One thread, years of context, all stored locally.
Ask for what you need in plain language. ZHAR can turn repeated workflows into reusable capabilities — built from how you actually work, not a plugin catalogue.
| Feature | ZHAR | ChatGPT | Claude | Siri |
|---|---|---|---|---|
| Where data is stored | Your device (AES-256 encrypted) | OpenAI cloud servers | Anthropic cloud servers | Mostly on-device; some cloud |
| Long-term memory | Months & years, on-device | Yes — cloud-stored, manually managed | Within Projects only, cloud-stored | Limited context from your apps |
| Builds new skills from conversation | Yes — from chat, automatically | No (Custom GPTs need manual setup) | No (Agent Skills need manual SKILL.md files) | No (Shortcuts only, manual) |
| Data used for training | Never | Yes, unless you opt out | Yes, unless you opt out | Yes, opt-out available |
| Open source (core) | Yes (planned) | No | No | No |
Real screenshots from the private beta. No staging, no stock photos.
One conversation thread. Clear context over time. No engagement optimization loops.
No dashboards. No setup maze. Just describe what you are trying to do and where you are stuck.
It remembers preferences, projects, and decisions so your next conversation starts from understanding, not from zero.
Repeated tasks can become reusable capabilities. The assistant gets better because your work gets better.
Client notes, privileged details, personal context — you need an assistant that can reference six months of conversations without sending a single word to someone else's server.
Lawyers, doctors, advisors, founders — if your work involves other people's trust, this is built for you.
| Typical assistants | ZHAR | |
|---|---|---|
| Memory | Forgets context between chats. | Remembers threads and projects over time. |
| Privacy | Cloud logs, opaque retention. | Encrypted on your device. No ad model. |
| Workflow | One-off prompts and answers. | Builds reusable evolves from what you already do. |

Get early accessZHAR's most unique feature: it turns your repeated workflows into reusable skills.
"Every week I prepare the same kind of client briefing — pull context from old conversations, check for conflicts, draft the summary. It takes an hour each time."
Not a single request — a recurring workflow that's costing you real time every week.
A reusable skill that pulls from your full conversation history, applies your formatting preferences, and knows which details matter to you.
One sentence. ZHAR drafts a structured brief — with context from six months of conversations, on your device, in seconds.
This is not a plugin marketplace. Evolves are born from how you actually use ZHAR — the requests you repeat, the patterns you don't even notice. No templates, no configuration screens, no code.
And because every evolve runs locally, the skill you build today stays yours — encrypted, portable, and invisible to everyone except you.
AI should reduce cognitive load, not increase dependency. It should protect boundaries and respect attention.
ZHAR is built for that standard: a personal assistant that stays useful, remembers what matters, and keeps data under user control.
"ZHAR lights your path. It does not own it."

Target: Q3–Q4 2026
Open-source modules, community contributions, and transparent implementation patterns for privacy-first AI systems.
2027
Product updates, new evolves, and curated industry news as they are released.
ZHAR is built by Oleg Butov, a founder and engineer in Berlin. After a decade of shipping tools for teams buried in notifications and fragmented workflows, he built ZHAR to answer a simple question: what if your assistant actually remembered you — without that becoming a privacy problem?
