Why AIToolsOnline

Built for the “no computer, just a browser” reality — without compromising on professionalism

Real agent capabilities

A professional agent loop built on the Vercel AI SDK: it understands tasks, plans, calls tools and executes multi-step workflows — far beyond a simple Q&A bot.

100% local data

Chats, settings and workspace files all live in your browser. No accounts, no servers — nobody else can touch your data.

Bring your own key

Use your own API key. The browser talks directly to DeepSeek / OpenAI / Anthropic with no middleman — pay only for what you use.

Professional document processing

Parse PDF, Word, Excel and CSV right in the browser: summarize long documents, extract key facts, compare files, generate reports.

Data processing & analysis

Ask the agent to query, filter and aggregate your spreadsheets, then save the results as new CSV / Markdown files.

Full-featured on mobile

A responsive, touch-optimized design gives phones and tablets the exact same complete agent experience as desktop.

FAQ

Is my data uploaded to a server?

No. This app has no backend: your chats, workspace files and API key all live in the browser's local storage (OPFS / IndexedDB). The only network requests go directly from your browser to the model provider you choose.

What do I need to get started?

Just a model API key (DeepSeek, OpenAI, Anthropic or any OpenAI-compatible service). No account, no installation.

Are features limited on phones?

No. Everything — document parsing, data processing, the file workspace — runs in the browser and is identical on phones, tablets and desktops.

Does my data follow me across devices?

Data is stored locally in each device's browser and is not synced. Clearing browser data erases everything, so download important files for backup.
