## Idea

One Hour, One Tile
A group-chat bot prompts each member to share one photo every hour, then automatically turns the day into a nighttime grid video of everyone’s perspective.

## Product concept

When friends are traveling, attending a wedding, or simply spending a day together, a group-chat bot collects one newly taken photo from each person every hour. That evening, it arranges everyone’s photos from the same hour into an animated grid; absent participants remain as empty slots, and late photos can fill in the story. The finished video preserves the different moments each person saw while eliminating the usual search through chat, cropping, and sequencing afterward.

## Why now (backed by facts)

On its TikTok trends page updated July 13, 2026, New Engen lists “Hour-By-Hour Friend Group Grid” as a format gaining traction: group-chat members send photos every hour, which are then combined by hour into a multi-perspective daily-record video. Within this observation window, it brings together what had been scattered across group chats, synchronized photo-taking, multiple perspectives, and an evening replay into a product-ready moment.

## Direction (model inference, not independently verified)

Target user: Organizers of trips, weddings, or short getaways, along with friend groups willing to participate lightly during the day. They open it before the event to set the rules, at each hourly prompt, and again that evening to quickly see what everyone else was seeing.

Minimal entry point: Start with a group-chat entry point that requires no new app. After someone creates a trip or wedding event, the bot prompts members to send one photo on each agreed hour and generates a downloadable hourly grid video when the event ends. The first version only needs invitations, timestamped photo filing, empty slots for absences, late submissions, and final-video export.

The strongest case against: Hourly prompts can quickly shift from a fun shared ritual to a persistent interruption. If people miss several in a row, empty slots may feel like failure rather than a storytelling device. A group-chat bot must also handle platform permissions, photo privacy, and time zones. And Setlog and HOur have already validated similar hourly, multi-person recording formats, so automatic grid assembly alone may not be enough to make users switch.

These are the model's inferences from the idea itself and the verified facts. Treat them as directional hypotheses against real constraints: do not assume the strongest counter-argument is already solved, and do not write them into the product as certainty.

## Punching above weight (model inference)

Build shareable finished-video examples around travel groups, wedding parties, and graduation trips, framing “what everyone was seeing at the same hour” as a short-video template. Give organizers a pre-event invitation link they can forward directly to the group, so one host brings in the whole group.

## Competitors & gaps (model inference)

- Setlog: Setlog already lets multiple people record hourly and automatically combines the clips into a split-screen video, but it is more like a standalone real-time video diary. One Hour, One Tile could live inside existing group chats and use photos, empty slots, and late submissions for one-off occasions such as trips and weddings.
- HOur: Take Picture Every Hour: HOur supports private groups, synchronized photo prompts, late-submission labels, and time-based collages, making its feature set very close to this product. The opening is lower-friction joining and a share-ready animated grid video generated directly from the event.
- Vlogit: Vlogit has friends take turns documenting a full day, emphasizing private groups and everyday memories. This product instead gathers everyone’s perspective at the same moment, rather than following one person’s story each day.

## How it makes money (model inference)

Create one event for free, then charge a one-time export fee per event. Paid upgrades unlock HD grid videos, watermark-free exports, and longer storage.

## Deliverables

- Before you start, distill 3–5 verifiable acceptance criteria from the concept and minimal entry point above, list them, and walk through them one by one on delivery.
- Ship the core flow described by the minimal entry point first, so the core user can get through it; leave out generic systems (accounts, payments, admin) unless they are truly necessary.
- Do not show unverified market numbers in the UI or API.
- Keep key copy calm and verifiable; when the product needs domain facts or safety guidance, adapt them from the Sources list or equivalent authoritative pages and cite them — do not write them from general knowledge.
- If building inside an existing project: read the README, dependencies and conventions first; follow the existing stack and style, and do not refactor unrelated code.
- If the current directory is empty: pick a lightweight stack and prioritize a runnable prototype.
- When done, explain what changed, how to run it, and how to verify it.
- Ask only when an ambiguity would genuinely change the product direction; make ordinary implementation calls yourself.
