ガイドとFAQ

不要です。ルーム ID で作成・参加するだけで協業できます。短い会議を軽く保つ設計です。ルーム ID は信頼できる相手にだけ共有してください。

デスクトップクライアントは不要です。最新ブラウザで参加できます。音声・カメラ・画面共有は初回にブラウザの許可が必要です。

最大 8 人。朝会、1on1、ペアレビュー、小さなワークショップ向けです。全社会や配信には大型会議ツールを使ってください。

最新の Chrome / Edge / Firefox / Safari。画面共有はデスクトップの Chrome / Edge が安定。IDE 内蔵プレビューでは画面キャプチャできないことがあるため、システムブラウザで開いてください。

すべての用途の代替ではありません。wbstorm は軽い一時的ハドル（短い同期、アーキスケッチ、共同描画）向け。大規模会議やウェビナー、管理機能が厚い用途はエンタープライズ製品が向きます。

ルームは一時的です。終了後、ボード画像は約 15 分間ダウンロード可能なことがあります。長期保管庫としては使わず、重要な内容は退出前に書き出してください。

はい。ルームでボードだけ使うか、ホームの個人フリー描画（端末のみ）を使えます。音声とカメラは必要なときだけ。

はい。登録や支払なしでルームを作成して協業できます。人数上限などは小規模会議を軽く保つためのものです。

On the home page, optionally enter a custom room ID (1–20 characters: letters, numbers, hyphen, underscore) or leave it blank to auto-generate one. Click create to enter the room as the admin session.

Copy the room ID from the address bar or the in-room UI and send it to participants. They open wbstorm, paste the ID under join, and enter — no account required.

If a room is closed or frozen, joining may still open the page for snapshot download while the file remains available.

Solo mode (/solo) is a personal whiteboard without a multi-user room; it is not indexed and is meant for private sketching.

When the browser asks for microphone permission, allow it for the wbstorm site. Denied permissions are the most common reason voice never starts.

Use headphones when possible to reduce echo. If you hear yourself looping, mute other tabs that might also capture audio.

Voice is optional. Many brainstorms only need the board. Unmute when a round needs argument.

If the call feels heavy, leave voice and stay on the canvas. A shared picture is enough for most product, design, and marketing rooms.

wbstorm has no screen share. The picture lives on the shared board. If the canvas looks empty, check that the top bar says connected.

Confirm everyone typed the same room ID. A one-character typo opens a different, empty room.

Refresh once. If the room was already closed, you can only download the leftover PNG — you cannot keep drawing.

IDE preview panes often cannot keep a live socket. Copy the link and open it in system Chrome, Edge, or Safari.

The board updates in near real time for all sessions in the room. Use shapes and text for structure; freehand for quick marks.

Agree on a rough layout (left = dump, right = decision) so people do not draw on top of each other chaotically.

The whiteboard complements voice: say the point, then pin it as a box or arrow so late joiners can catch up visually.

When the admin closes the room, download the PNG snapshot if you still need the diagram — the room itself is removed promptly.

Active rooms expire after a configured TTL (on the order of hours). Plan important discussions inside that window, or create a new room if you need another session later.

When an admin closes the room, live collaboration ends and capacity is freed immediately. The product is intentionally ephemeral — not a permanent archive.

Optionally, a PNG snapshot of the whiteboard is retained for a short period (minutes) so participants can download it. After that, it is gone.

Do not rely on wbstorm as long-term storage. Export anything you must keep before the snapshot TTL ends.

Each room supports up to eight people. The cap is on purpose: a brainstorm needs one picture everyone can still see, not a webinar.

If the room is full, open a second room and split the group, or wait for a seat. Do not treat wbstorm as an all-hands tool.

There is no screen share. Camera is optional. Bandwidth stays with the canvas and optional voice.

Large all-hands belong in a broadcast tool. Break into wbstorm rooms when you need a small group around one sheet.

Open the same site in a current mobile browser and join with the room ID. Grant microphone permission if you want to talk.

Keep the phone unlocked and the tab visible; backgrounding can pause WebRTC on some devices.

There is no screen share. Phones are best for listening and light marks; complex journeys belong on a laptop.

If the layout feels cramped, rotate to landscape or switch to a laptop for board-heavy sessions.

You do not create a wbstorm user profile to brainstorm. Access is gated by knowing the room ID (and admin capabilities for the creator session).

Share room IDs through channels you already trust (team chat, calendar notes). Avoid posting active IDs on public social media.

Room state is short-lived. When a room ends, live collaboration stops; snapshots exist only briefly if enabled.

Ephemeral design reduces leftover archives, but you are still responsible for what you draw or say in the room.

The session that created the room holds admin privileges. Use the close control when the meeting is done instead of leaving the tab open until TTL.

Closing removes the live room right away so others can create rooms under the global capacity limit.

If you need the board, confirm snapshot download is available and grab the PNG before the short retention window ends.

Participants who reconnect after close will not resume a live board — only snapshot download may remain for a while.

wbstorm uses WebRTC for media. Strict corporate firewalls or some VPNs block peer connectivity. Switching to a phone hotspot is a quick test.

Update to a current Chrome, Edge, Firefox, or Safari. Embedded in-app browsers sometimes break getUserMedia or WebRTC.

If voice connects but video does not, re-check camera permissions and the room’s camera cap.

Still stuck? Close other heavy tabs, recreate the room, and have everyone rejoin with a fresh ID to clear a bad session mesh.
