The same research method on every plan. You choose which library it reads.

Pricing plan

One method. Choose which library it reads.

Every plan runs the same research engine — the free one included. What a plan decides is which library becomes unlimited, not how good the method is.

Included in every plan, free and paid

  • 19 research skills, and growing — takhrij, dirasat al-asanid, rijal, tabaqat ashab al-shuyukh, ʿilal, muqaranah, qawaʿid al-jamʿ wa qara'in al-tarjih, kashf al-wadʿ, mukhtalaf, mustalah and more.
  • The order is enforced, not suggested — thubut before naqd, naqd before dilalah. Eleven of those skills cannot run alone at all.
  • The answer is checked before you see it — a claim whose source is not in the gathered evidence does not pass, and a paragraph that asserts without one is sent back.
  • The work is proven, not asserted — every tool run is signed, so the assistant cannot claim research it did not do.
  • It tells you what it could not do — a part of the method the tier cannot reach is named in the answer, instead of quietly missing from it.
  • Citations open — book, volume and page, one click. Where a printing has no page numbers it says so rather than estimating one.
  • Findings accumulate — a study you finish comes back on the next question, in either app, and what another researcher independently confirms is offered to you.
