Zetik is a mobile app only, and no web version is shown on its official site, so laptop users have nothing to read on. It publishes no pricing at all, which makes cost comparison impossible before installing. The App Store link goes through a redirect service, so iOS availability was not directly confirmed, and an account is required with users under 13 not permitted.
Perplexity is an answer engine with cited sources and a free tier; the listed starting plan is Education Pro for verified students and faculty at $10 per month. Gemini Notebook (formerly NotebookLM) answers questions from your own sources, with a free tier and no price stated. Google Gemini is a multimodal assistant, free with higher limits via Google AI Plus at $4.99 per month. ChatGPT is a general assistant with a free tier and Plus at $20 per month. None of these is described as folding duplicate coverage into one briefing like Zetik.
"Better suited" below is based on documented features and pricing from our verified profiles, not on a head-to-head test. Prices are USD as published by each vendor.
Taken from the documented limitations in our Zetik profile.
| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| Zetik (this page) | Not published | No | Mobile | The site publishes no pricing, no web version is shown (mobile app only), and the privacy and docs pages are unavailable. |
| Perplexity | $10/mo (Education Pro (consumer, verified students/faculty)) | Yes | Web, API | The consumer pricing page is blocked to automated checks, so the Pro price could not be confirmed here, and free-tier Pro Search and Research access are described only as 'very limited' / 'limited'. |
| Gemini Notebook (formerly NotebookLM) | Not published | Yes | Web, Mobile | Free tier has standard usage limits and 50 sources per notebook; higher limits need a Google AI Plus, Pro or Ultra plan, which Google says are only available in specific regions. |
| Google Gemini | $4.99/mo (Google AI Plus) | Yes | Web, Desktop, Mobile | Usage is governed by compute-based limits that refresh every 5 hours up to a weekly cap, and free-tier chats with Keep Activity on are used to train Google models with human review. |
| ChatGPT | $20/mo (Plus (consumer)) | Yes | Web, Desktop, Mobile, API | Almost every tool (uploads, images, voice, deep research, Codex) has plan-dependent usage caps that OpenAI states can change over time, and the API is billed separately from every ChatGPT subscription. |
