Practice your deen. With receipts.
It's before fajr. A question won't let you sleep. By the time you've made wudu, you have the matn, the chain across the schools, the gradings, and the disagreement — with receipts you can show your imam.

THE FOUNDATION
We built the hadith science first. Then the AI.
95.9%
Independent sahih+hasan rate on Sahih al-Bukhari
Our computational grading pipeline independently produces sahih+hasan rates very close to classical compilers' selection criteria — without being trained on their conclusions. The 4.1% divergence has documented causes (PID disambiguation, anonymous-narrator penalties, mu'allaqat, deliberate weak chains for topical completeness).
Honest note: prior IPSC releases reported 97.3% — corrected to 95.9% in v3.8 after the cluster rebuild surfaced inflated supportingChain counts. v3.8 changelog.
Narrator reliability
12-Tier Grading System
Every narrator assessed across 12 tiers of scholarly reliability — from the most trustworthy to the fabricators.
T1–T3Thiqah · Highly reliable
T4–T5Saduq · Truthful
T6Maqbul · Acceptable
T7–T8Da'if · Weak
T9Matruk · Abandoned
T10–T11Muttaham · Accused
T12Kadhdhab · Fabricator
Hadith authentication
Five Conditions of Authenticity
Every narration evaluated against the classical five conditions that scholars have applied for over a millennium.
- Chain continuity اتّصال السند
- Narrator uprightness عدالة الرواة
- Narrator precision ضبط الرواة
- Absence of anomaly عدم الشذوذ
- Absence of hidden defect عدم العلّة
HONEST GRADING
Not everything is sahih. That's how you know it's real.

22%
22% not graded — rather than force a classification, the corpus openly marks these narrations as ungraded. This reflects scholarly honesty: acknowledging the limits of current verification rather than overstating certainty.

THE DIFFERENCE
They trained a chatbot. We built the hadith science.
Generic AI
- Fabricates hadith that don't exist
- No source citations
- Can't distinguish Sahih from Da'if
- Hallucinates scholar opinions
TheoAI
- Cites every hadith from verified collections
- Full source chain for every answer
- Grades every hadith: Sahih, Hasan, Da'if
- Traces narrator chains and identifies weaknesses

Gift a Subscription BUILT FOR HOW YOU PRACTICE
Theo speaks Muslim, not just Islam.
Generic chatbots translate Islam. Theo is built around how Muslims actually live the faith — the calendar you follow, the script of your language, the forms of honor you give. None of this is a setting we copied from another AI product; none of them have it.
Choose your Hijri authority
Umm al-Qura, academic, or local sighting. Theo respects the calendar you follow — not the one Silicon Valley defaults you to.
Dhul Hijjah tracker + Qurbani calculator
The 13-day Dhul Hijjah counter, day-specific prompt starters, the Qurbani estimator. Built in. Ramadan and post-Ramadan goal capture too.
Honorifics rendered per locale
ﷺ in Arabic. درود on Urdu. SAW in transliteration. Arabic-Indic numerals in Arabic. Auto, every time — no manual switching.
Spiritual vs playful celebrations
Reach a milestone? Confetti, or a quiet barakallahu feek. Your choice in settings. Dignity and joy are both Islamic — Theo lets you pick which one fits your house.
