Gemini Live, Gemini Spark / Canvas & Custom Gems

The Gemini app is no longer just a text box. With Gemini Live, staff point their phone camera at faulty equipment, a job site, or a whiteboard while talking hands-free. Back at the desk, Gemini Spark / Canvas and Custom Gems turn one-off prompts into interactive calculators, mini-apps, and standardised company specialists.

Core capabilities

Gemini Live (Voice + Camera & Screen Sharing)

Hold a natural, interruptible spoken conversation with Gemini while showing it your live phone camera feed. Walk a renovation site pointing at damaged cladding while dictating dimensions; Gemini organises the scope of works by room.

Gemini Spark / Canvas (Interactive Co-Creation & Mini-Apps)

A side-by-side workspace where Gemini writes, edits, and runs live interactive calculators, quoting tools, dashboards, and long-form documents in real time — without hiring a software developer.

Custom Gems (Repeatable Role Specialists)

Save custom instructions, tone rules, and Google Drive reference files into a named “Gem” (e.g. a Variation Quote Gem or NZ Employment Clause Gem) so every staff member follows the same standard.

Deep Research Agent

Autonomously plans a multi-step research strategy across dozens of authoritative sources and compiles a fully cited market, supplier, or regulatory report in minutes.

Real-world New Zealand business examples

Trades & Field Services

22-staff plumbing & gasfitting firm (Waikato)

Bottleneck: Estimators spent 2 hours every night typing up messy voice memos and site photos into variation quotes.

Workflow: Estimators use Gemini Live camera mode on site while speaking out loud, then run the transcript through a Custom “Variation Quote Gem” grounded in their master rate card.

Outcome: Cut evening quote admin from 10 hours/week to 90 minutes; quotes go out the same afternoon.

Professional Services

14-staff commercial property advisory (Christchurch)

Bottleneck: Building custom lease-vs-buy and fitout ROI calculators for client pitches tied up senior analysts for days.

Workflow: Advisors use Gemini Spark / Canvas to generate interactive HTML yield calculators during client prep, paired with a Custom Gem trained on past memorandums.

Outcome: Interactive pitch assets built in 15 minutes instead of 2 days.

Wholesale & Operations

45-staff agricultural parts importer (Palmerston North)

Bottleneck: Identifying worn parts from farmer photos and translating overseas service bulletins slowed down the parts counter.

Workflow: Counter staff use Gemini Live camera share and a Custom “Parts Spec Gem” grounded in Drive catalogues to cross-reference OEM numbers and draft replies.

Outcome: 40% faster parts identification across junior counter staff.

When it is the wrong tool: Custom Gems inside the standard Gemini interface require a human to start the chat. They cannot run unattended at 2:00 AM or write directly into external databases — use Google Workspace Flows or a custom Antigravity / Gemini API agent for unattended background jobs.
