Your data never leaves your machine in either version: the website parses files in your browser; the desktop app uses its own local server. The desktop app additionally reads binary formats and runs local AI, which a browser cannot do safely.

We found two different versions of your Data Flow workspace. This happens when you work offline and later connect, or use the tool on multiple devices simultaneously.
This is the workspace synchronized from your user profile online.
This is the most recent local backup saved on this machine's disk.
Selecting one version will overwrite the other.

You don't need a five-figure enterprise license or a sprawling cloud infrastructure to master your data. Datok is the all-in-one data processing, cataloging, and visualization platform built for solo professionals, small business owners, students, and agile corporate workers who want enterprise-grade power without the bloated price tag.
For just a fraction of the cost of legacy software, Datok replaces your fragmented data stack. It combines the intuitive, no-code heavy lifting of the industry's best data prep software, the deep metadata tracking of top-tier data catalogs, and the rich visual storytelling of premium business intelligence dashboards into a single, seamless environment.
Datok is accessed easily through your web browser, but 100% of the data processing happens locally on your machine. This unique architecture provides three massive advantages:
Your sensitive datasets never leave your computer. No cloud uploads, no external servers, no compliance headaches. You maintain total control over your information.
Because Datok leverages your local CPU and memory, there are no hidden cloud compute fees or bandwidth limits. The performance scales entirely with your hardware—the better your rig, the faster your flow.
Got a capable machine? Datok allows you to seamlessly plug in local Large Language Models to enrich, analyze, and query your data. Get private, generative AI insights against your private datasets without ever paying a cent in API fees to big tech.
Enjoy full access to all local Datok features — ETL workflows, worksheets, dashboards, and local AI.
Includes all Datok features plus the active **OmNexis lookup tool** for 1,000 API requests per month (resets 1st of month). Only info for existing name+country records is returned; missing entries are indexed over time.
Whether you are a student crunching complex research data, a sole proprietor mapping sales trends, or a corporate analyst building workflows locally to bypass IT red tape, Datok gives you the tools to let your data flow.

Create a one-line message (e.g. a known issue or maintenance notice). When you turn it on, every logged-in user sees it at the top of Datok (web & desktop) on their next login or refresh. Once on, the text is locked; turn it off and it moves to the history below. Only one warning can be active at a time.
Monthly subscription movement and trial-conversion history. The current month is live; past months are fixed.
Reference list of standard procedures for Datok developers and maintainers.
Every update to the Datok codebase must include an increment of the internal DATOK_VERSION variable in app.js by exactly 0.001. Additionally, update the DATOK_VERSION_DATETIME string.
All backend changes must be deployed to the VPS via SCP (e.g. scp start.py ...). Afterwards, the python server must be forcefully restarted using kill (locating the exact PID) and nohup python start.py > server_debug.log 2>&1 & from inside the venv/bin/activate context, because killall python3 will silently fail to match the virtual environment process name.
Hardcoding explicit user profile overrides (e.g., forcing a specific user to a particular country on login) is strictly prohibited. Testing overrides must be reverted before deployment to avoid data overwrite bugs in production.
Always ensure that the local copy of the codebase (C:\AG\dejta) remains perfectly in sync with the live server. Test changes locally before blindly pushing them to the VPS.
When the user works offline, workspace settings are saved to localStorage with a datetime stamp. When the connection to datok.eu is re-established, the system compares the local timestamp with the server's timestamp. If there is a gap of 5 minutes or more, a warning prompt appears asking the user whether to keep the newer Local offline settings or the Server settings, preventing accidental overwrites.
Data Operations Workspace
All datasets and databases are processed and stored locally on your machine. We do not send your files or data to any external cloud, guaranteeing complete security and privacy. Since all calculations and ingestions run locally, your machine's hardware (RAM, CPU, and disk speed) directly affects processing times and capabilities.
Need clarification on a tool? Simply right-click any tool icon in the Prep palette (or click the help icons) to open its dedicated quick-reference guide immediately. You can also head over to the Info tab at the top to access the searchable user manuals at any time.
Datok's AI-enabled tools (like AI Text) run entirely offline and locally when Ollama is installed on your machine and at least one LLM model (such as llama3.2) is downloaded. This protects your enterprise data streams from external exposure.
We are sorry to see you go! If you cancel, your account will remain fully active with access to Datok until the end of your currently paid period (N/A).
Only one main Datok workspace window can be active at a time to prevent data corruption and database lock conflicts. You can launch report viewers, temporary analysis tabs, and help windows separately.
