ASEAN Perspective
Liner in Southeast Asia
ASEAN-region availability and pricing notes coming soon. Drop the editorial team a note via /contact/ if you can supply local context (Singapore/Malaysia/Indonesia/Thailand/Vietnam).
Liner is a polished, research-focused alternative to general chat tools, and its Scholar mode plus per-line citations make it genuinely useful for literature reviews and student work where source traceability matters. The browser, PDF and YouTube highlighting integrations are a nice differentiator.
It is a productivity layer over underlying frontier models rather than a model itself, and serious accuracy claims should be spot-checked against primary sources. There is no developer API, and the most useful features sit behind a paid plan, so the free tier is more of a trial than a daily driver.
