Tools

Turn on the exact help the answer needs.

The tools button keeps live search, image generation, official economic data, voice mode, and canvas one tap from the prompt box. Turn on the capability the task needs, keep files nearby, and stay in the same chat while the work changes shape.

Add File sits beside the tools, so sources and attachments stay close to the prompt.

Explicit surface

What you turn on stays visible and easy to trust.

just4o.chat does not bury tool access behind a vague agent mode. The point is simple: reach the right capability when you need it, see what is active, and keep the conversation, files, and output in one working flow.

VisibleActive tools stay shown beside the composer, so you can tell what this chat can do at a glance.

SelectiveTurn on only the capability the task needs instead of getting dumped into a one-size-fits-all mode.

In flowSearch, images, data, voice, canvas, and files stay in the same working surface instead of scattering you across tabs.

HonestIf a model cannot use a tool, just4o.chat leaves it unavailable instead of pretending the capability is there.

Web Search

Pull the live web when the answer needs the present tense.

Web Search is for questions that need current facts, fresh links, and sourced answers. In supported model paths, just4o.chat can browse the live web and bring that reporting back into the same thread.

Useful for news, releases, pricing checks, live references, and anything where the answer can go stale.

Search can also switch on when the prompt clearly asks for research or the latest information.

Availability and daily allowances depend on your plan, and unsupported models keep the tool off instead of bluffing.

Read web search docs

Best forCurrent events, research, live references, and questions where dates matter.

What you getFresh sources and answers grounded in live pages instead of static memory alone.

Model supportAvailable on supported closed-source model paths.

Plan accessDaily search allowances scale by tier.

Generate Image

Let the answer return generated images, not just text.

Generate Image lets a chat answer come back as a visual, not only copy. Describe what you want, stay in the same conversation, and let your saved image preferences carry the style.

Good for concept work, scene directions, product mockups, and quick visual variations.

Image settings live in Account, so the defaults travel with you instead of being renegotiated every time.

Generation only runs when the account has the right tier access or available image credits.

Best forConcepts, illustrations, mockups, and visual variations inside chat.

ExperienceThe image request stays part of the same thread instead of kicking you into a different product.

SettingsSaved image preferences apply automatically.

AccessRequires a paid tier or available image credits.

Economic Data

Call official U.S. data with charts and raw tables.

Economic Data is for labor, inflation, energy, and related U.S. series from official public sources. It helps turn a vague macro question into something you can actually read, compare, and use.

Built around U.S. Bureau of Labor Statistics and Energy Information Administration data.

Useful for inflation checks, labor snapshots, energy comparisons, and quick macro context.

Returns readable trends plus the numbers behind them, so the answer is more useful than a hand-wavy summary.

Official U.S. sources

Readable trends when you need the shape. Real numbers when you need the proof.

Why it helpsBetter for analysis than asking a model to vaguely remember macro data.

Voice Mode

Keep talking without leaving the thread.

Voice Mode keeps speech and playback inside chat. Use the mic in the composer, let replies read aloud when they finish, and keep your chosen chat model at the center of the conversation.

Tap the mic for speech-to-text, or turn on Voice Mode for a more continuous hands-free loop.

Voice model, playback voice, silence timing, and related controls live in Account settings.

It works as part of chat, not as a separate voice app with a hidden model swap.

Canvas

Open an editor beside the thread instead of bouncing to another app.

Canvas launches straight from the tools menu into the collaborative editor. Open a blank draft, keep it attached to the conversation, and work beside chat instead of juggling windows.

Useful when the answer wants to become a real draft, brief, outline, or working file.

On desktop it can live beside chat; on mobile the app switches between chat and canvas tabs.

Once open, it becomes a working file surface with review controls and save behavior built in.

Save pathKeep the file attached to the same conversation or project.

Keep the tool surface honest and the workflow fast.

Open chat, turn on the capability the task actually needs, and keep search, images, data, voice, canvas, and files inside one working surface.
