Open this AI tool now
https://liner.com/Liner, developed by Seoul-based Liner, combines web search, academic literature analysis, and document drafting into a single platform. For students and researchers who need cited answers and want access to multiple frontier models without juggling separate subscriptions, it is a convenient workspace. However, casual searchers will find the ad-filled free tier frustrating, and privacy-conscious users should note its data limitations.
Research and Drafting in One Window
Liner organizes its workspace into three products under one subscription: Liner for search, Liner Scholar for academic research, and Liner Write for drafting. Rather than relying on a single engine, it aggregates over 350 AI models, including 306 LLMs and 55 image generation models from OpenAI, Google, Anthropic, DeepSeek, and Meta. Users can tap into models like GPT-6.1 Terra, Gemini 4 Argon, and Claude Haiku 5.5 within the same interface.
Tired of juggling ten tabs? ToolSuite bundles the AI workflow tools power users rely on — in one place.
Try ToolSuite NowFor scholarly work, Liner lets you open every citation with one click and map topics with mind maps, while Liner Scholar offers literature reviews in minutes and specialized agents like a Hypothesis Generator and Citation Recommender. While general users often prefer Perplexity for web discovery, and academics turn to dedicated tools like Consensus or Elicit for deep paper extraction, Liner focuses on uniting search, academic discovery, and writing in one window.
Pricing, Ads, and Restrictive Catches
Liner bills in US Dollars, offering monthly plans or annual subscriptions discounted by 17%.
| Plan | Price | What You Get |
|---|---|---|
| Free | $0 | Search with ads, deep research access, 1 file upload per day (up to 25MB), limited credits. |
| Pro | $17.99/mo ($14.99/mo annually) | Ad-free, 350+ models, Liner Scholar and Write, 20 file uploads per day (up to 100MB). |
| Max | $35.99/mo ($29.99/mo annually) | Ad-free, 350+ models, full suite, unlimited file uploads per day (up to 200MB per file). |
| Team | $26.99/mo per seat | 2-20 members, Max features, centralized billing, admin controls, data excluded from AI training. |
| Enterprise | Custom | All Team features, dedicated manager, onboarding, audit logs, and volume discounts. |
The free tier carries noticeable drawbacks: answers display ads, and free credits run out quickly after a few tasks. File uploads on the free tier are capped at one 25MB file daily. Furthermore, Liner says it does not offer refunds; only residents of the EU, UK and Turkey get a 14-day refund window. Subscriptions renew automatically unless cancelled at least 24 hours prior to billing, and purchased credit packs expire after 6 months.
Data Privacy and Training Realities
Users retain copyright over their content, but grant Liner a license to store and use it for service operations and improvement. Liner also states that staff may review user content internally. Crucially, the pricing page promises exclusion from AI training only on the Team tier, so assume individual plans carry no such promise. Accounts are restricted to a single user with credential sharing banned.
The Arabic-Language Research Test
Liner states nothing regarding Arabic language processing, right-to-left (RTL) formatting, or Middle Eastern regional pricing. Before paying, Arabic-speaking researchers should run this 5-minute test:
- Prompting: Ask a research question written in Arabic, for example on renewable energy in Gulf economies, and check whether the answer stays in Arabic and on topic.
- Citations: Verify whether Liner Scholar finds genuine peer-reviewed Arabic studies or only English sources.
- Layout: Check if responses display cleanly right-to-left without broken punctuation, reverse brackets, or corrupted mixed-language text.
Who Should Buy Liner and Who Should Skip It
Liner is worth the price for students and researchers who want an all-in-one hub combining search, literature reviews, drafting, and access to over 350 models under a single subscription. However, skip it if you need guaranteed privacy on individual plans, rely on a truly capable free tier, or require verified native Arabic research capabilities.
