Google’s Gemini Spark and Perplexity Computer reveal divergent AI assistant futures

As Google’s Gemini Spark and Perplexity Computer carve separate paths, they exemplify contrasting visions of AI assistants: integrated productivity tools versus flexible digital workers, marking a pivotal shift in AI deployment and usability.

Google’s Gemini Spark and Perplexity Computer point to the same shift in AI: assistants that do the work, not just answer the question. But the two products are taking different routes. Gemini Spark is built to work natively inside Google’s own services, while Perplexity Computer is designed as a broader digital worker that can move across a wider range of apps and models. The difference matters because it shapes both usefulness and reliability.

According to Google’s product support pages and coverage from TechCrunch, Gemini Spark is intended to handle multi-step tasks across connected services such as Gmail, Docs and other Google Workspace tools, with access to personal context, websites and location when authorised. Google says it can be used for tasks such as summarising inboxes, drafting replies and producing research with cited sources. It is also restricted to users aged 18 and over with a personal Google account. TechCrunch reported that Spark was first launched for Google AI Ultra subscribers and is expected to gain additional connections over time.

That tight integration is also Spark’s main weakness. Android Authority argues that the tool is at its most useful when the user already lives inside Google’s ecosystem, because it can draw on first-party context without the overhead of external connectors. The downside is that it is far less flexible once work moves beyond Google’s own apps, and it cannot draw on rival models in the way Perplexity can. That makes Spark feel convenient and approachable, but also more constrained.

Perplexity Computer, by contrast, is built around orchestration. Perplexity’s own help pages say the company uses a mix of models from providers including OpenAI and Anthropic, and its Computer product is aimed at long-running workflows, browser automation and app connections across tools such as Gmail, Slack, Notion and Calendar. Tom’s Guide recently reported that Perplexity has also introduced a local-first Portable Computer mode, which begins tasks on-device and only asks before using cloud models. That approach adds privacy and control, although it currently depends on demanding hardware and Linux support.

Android Authority’s comparison suggests that this makes Perplexity the more mature tool for demanding, business-like work, while Spark is easier to use and cheaper to access. Spark’s broad appeal comes from its simplicity and lower price, with Google making it available beyond its highest subscription tier. Perplexity Computer remains the more expansive option, but at a far steeper cost. In practice, the choice is becoming clear: Spark is the friendlier assistant for people already inside Google’s world, while Perplexity is shaping up as the stronger platform for users who want a more general-purpose AI worker.
