Features

Chat with top AI models plus an autonomous agent that edits files, runs commands and gets the job done

Chat with top AI models

Gemini, Claude, GPT, GLM and more: streaming replies, model thinking, Markdown, LaTeX, Mermaid, Ctrl+V screenshots, attachments and vision.

Autonomous agent

Give it a task — the agent plans the steps, reads files, makes edits, runs commands and finishes the job with a report.

Safe by default

Dangerous actions require a confirmation card in the chat; full access is a 24-hour trust session, and everything is journaled.

Your files stay intact

Edit guard: if a file would no longer parse after an agent edit, the change is rejected before it is written. Snapshots and revert_file undo any change.

Server work

SSH connections to your machines: run commands and transfer files right from the chat.

Memory and cloud

AI memory keeps facts across chats; profiles and settings sync between computers via your license key.

Plan mode and run control

An agreed plan first, actions next: the agent shows the steps and you adjust them before launch. Messages can be queued, runs stopped instantly with Stop, and follow-ups sent out of queue.

Long tasks, nothing lost

Automatic compression of long dialogs, auto-retry on network and provider errors, an edit journal and targeted revert. Models with up to 1M tokens of context are supported.

Chats and projects

Multiple parallel chats: each has its own working folder and AI profile. Drafts, history and file snapshots are saved automatically.

How it works

From task to done — the agent handles the busywork

Install & launch

Download the portable Windows build, unpack it anywhere and run the exe. No installation — all data stays next to the program.

Connect a model

Paste your provider API key — or use FDAgentAi from your subscription: no key needed, tokens included.

Describe the task

Ask in chat or brief the agent: "figure out this project", "fix the failing tests", "write a script". Attach files or screenshots.

Watch it work

Edits, commands, searches — all visible in a live feed. Risky steps are approved via a diff card, the agent's plan — with one click. Long tasks keep running in the background even if you close the chat.

Control & safety

The agent runs sandboxed inside your working folder: every edit and command needs your approval. File history and checkpoints let you undo any step.

Take the result

Finished files land in your working folder. Settings sync to the cloud via your license — everything at hand on a new PC.

Frequently asked questions

What is FDAgent?

A Windows desktop app: chat with AI models plus an autonomous agent that works with your files and commands right on your computer.

Does it need internet access?

Yes, for the language model. All file operations and commands run locally — your code is never sent anywhere. Web search is a separate toggle.

Which models are supported?

OpenAI, Anthropic, DeepSeek, Google Gemini and any OpenAI-compatible API — paste your key in settings. Keys are stored encrypted, locally. Or use FDAgentAi from your subscription.

What is Plan mode?

A mode where the agent first shows you its action plan and waits for your approval before executing it. Great for large tasks: you agree on the approach before any file is touched.

Is it safe for my files?

Yes. The agent works in a sandbox by default: edits happen in a copy, commands are isolated, and every change is revertible. Risky actions require your approval — with a before/after diff shown.

What is included in the subscription?

FDAgentAi tokens (work without your own key), all updates during the subscription, cloud settings sync, up to 3 devices per license. Trial period — no card required.

How is a license activated?

After payment a FDA-XXXX-XXXX-XXXX key appears in your account. Paste it into FDAgent settings — activation takes seconds.

Can I move it to another computer?

Yes, the app is portable — just copy the folder. Settings and profiles restore from the cloud backup tied to your license key.

Can I use it on multiple computers?

Yes, up to 3 devices per license. Devices can be unlinked from your account at any time.

Does FDAgent work without a subscription?

Yes. The Free plan is free of charge: bring your own AI key (Gemini, [OI], Anthropic, GLM, etc.) and work without FDAgentAi limits. FDAgentAi tokens come with Lite and PRO subscriptions and one-time packs.

What are FDAgentAi tokens?

Tokens are the amount of text processed by the built-in AI models. Subscriptions refresh the balance monthly; the remaining balance and usage history are visible in your account.

What are the system requirements?

Windows 10/11 (64-bit). The portable version needs no installation — just run the exe.
