How it works | PingBack

The mechanics

PingBack reads every sticky note on your Miro board and sends each one individually to Claude, Anthropic's AI model. Claude returns a single question per sticky. PingBack places it immediately beside the original as a cyan sticky note, marked with 🏓, at a fixed offset so it never covers your content.

It doesn't summarise. It doesn't rephrase. It doesn't add suggestions or alternatives. It places one question, then stops.

Three ways to use it

Open PingBack from the Miro toolbar. No configuration. It starts watching your board immediately.

Reactive mode (always on)

Write a new sticky and PingBack places a provocative question beside it within 3 seconds, no clicks needed.

Selection mode

Select stickies already on the board and click PingBack X stickies to question only those.

One-click clear

Click Clear PingBacks to remove every generated question note from the board in one action.

Visit pingback.work and connect your Miro account via OAuth. No tokens or API keys required.

Full board in one run

Paste your board URL and click PingBack this board. Up to 200 stickies, one question each, shown instantly.

Frame filter

Pick a specific Miro frame and PingBack reads only stickies from that frame. Great for focused retrospectives.

Live translation

Switch the language selector before or after running to translate all questions into 8 languages without rerunning.

Run again

Regenerate all questions on the same board with one click. No page reload, same session.

Visit pingback.work and click Connect with Mural. Authorise via Mural OAuth. No API keys or tokens needed.

Full mural in one run

Paste your mural URL and click PingBack this mural. PingBack reads every sticky on the canvas and shows questions instantly.

Live translation

Translate all questions at any point during or after the run using the language selector.

Run again

Click Run again to regenerate questions on the same mural without leaving the page.

After generating questions, click Open N questions to enter full-screen presentation mode. Works on any device.

Host controls

Click any card to mark it "Discussing now". That card scrolls into view on every participant's phone within seconds.

QR code for participants

Scan and join without a login, download, or Miro account. Participants see the same live question list on their phones.

Live audience reactions

Each card carries a reaction bar so the room responds silently. Counts tally live across all phones and the host screen.

Sessions valid 2 hours

Extend from inside the view if you need more time, or end it early so a leaked link can't be reused.

Why it's different

Most AI tools summarise, reframe, or suggest. PingBack does none of that. The entire prompt is built around one principle: before questioning the idea, question the premise behind it.

Claude is instructed to operate in what we call Provocative Mode: a set of strict rules that force the question to go deeper than the surface of the sticky.

Provocative Mode

If the sticky describes a solution: ask about the problem it assumes.

If it describes a problem: ask who defined it and why they're right.

If it describes a process: ask what it would take for that process to fail silently.

Always look for what the team treats as settled but hasn't examined. Name the tension the sticky is avoiding, then ask about it directly.

What the question looks like

Not a checklist item. Not a reflection prompt. Not "have you considered…". One sentence, present tense when possible, addressed to the team rather than the sticky. The kind of question the room has been carefully avoiding.

Examples

"Who decided this is the right problem to solve, and when were they last challenged on that?"

"If this process worked exactly as designed, what assumption about your users would turn out to be wrong?"

"What would the team that built the competing solution say is wrong with your framing here?"

The live audience loop

The presentation view is more than a slideshow. Each card carries an emoji bar (👍 💛 🔥 👀 🤔) so the room can react silently while the host speaks. Reaction counts update live on every phone and on the host screen.

When the host clicks Next question from reactions, PingBack reads the dominant emoji on the focused card, picks an agentic move, and asks Claude for a follow-up that builds on the parent question. The follow-up is appended as a new card with a visible trace: which question it came from, which move was used, which emoji dominated, and the exact reaction tally at that moment. Nothing about the agent is hidden.

Challenge the easy agreement

Make the cost of "yes" visible.

Surface the buried assumption

Name the premise that's tripping them up.

Double down on the heat

Press harder on the same nerve.

Name what nobody is saying

Call out the elephant in the room.

Pull on the human stake

Ask about the people, not the abstraction.

LLM-as-judge, side by side

Click the score badge on a follow-up card and PingBack scores both the parent question and the follow-up against the same rubric (Provocation, Premise, Brevity), in parallel. The result is shown side by side so you can verify whether the agent actually made the question sharper, not just longer. See how the score is calculated →

Designed to never freeze on stage

If Anthropic times out or rate-limits mid-session, PingBack returns a curated fallback question from a built-in bank within milliseconds and labels the card honestly so you know what happened. The session keeps moving. Every shared link is rate-limited per IP and load-tested to handle 120+ concurrent phones polling at the same time, with sub-10ms p95 latency.

What PingBack does not do

It doesn't validate. It doesn't encourage. It doesn't offer answers, alternatives, or summaries. It doesn't carry context between boards, sessions, or runs. The only memory it keeps is inside one live presentation, where each follow-up question knows which earlier question it built on. As soon as the session ends, that context is gone. Sticky text is sent to Claude only to generate the question, never logged or used to train anything.

When it's most useful

Early in a sprint, when assumptions are still unexamined. Mid-retrospective, when the conversation is staying comfortable. During problem framing, before anyone has agreed on what's actually being solved. In any session where the team is moving fast and hasn't stopped to question the ground they're standing on.

PingBack is not a facilitation tool. It doesn't run the session. It interrupts it. Briefly, precisely, at the right moment.

Built for facilitators

Workshop facilitators, agile coaches, design sprint leads, and consultants run sessions where the hard part is not collecting ideas. It is challenging them. PingBack does that part for you, on every sticky, in seconds, so you stay focused on the room.

Multilingual rooms

International teams switch the question language in one click. PingBack translates every question into English, Portuguese, Spanish, French, German, Italian, Japanese, or Chinese without losing the provocative edge. The same session can switch languages live, so a Spanish-speaking participant reads in Spanish while the host facilitates in English.

Phones in the room

Open the presentation view and PingBack shows a QR code in the corner. Participants scan it, the questions load on their phone, and they follow along without an account, a download, or a Miro license. Useful when the team is hybrid, when only the host has Miro, or when you want everyone reading on their own screen instead of squinting at a projector.

Keep the room in sync

Click any question card on your screen and that card scrolls into focus on every participant's phone within seconds. A clear "Discussing now" badge tells everyone where the conversation is. No need to call out question numbers or wait for people to find their place. The host leads, the room follows.

Scope to a frame

Boards get crowded. If your session lives inside a specific Miro frame, pick it from the frame selector and PingBack only reads stickies from that frame. Run a single retrospective ritual on a board that holds twelve other workshops without polluting the rest.

Two hours to run the session

Each shared session stays live for two hours. Need more time? Extend it from inside the presentation view in one click. Done early? End the session immediately so a leaked link cannot be reused.
