FIVE MODES
Choose your depth.
Auto picks for you. Pick yourself for the depth you want — from a quick lookup to an in-depth investigation with chain-of-verification. Plus tier unlocks Reasoner; Tahqiq tier unlocks Deep and Tahqiq modes (and Plus users get one Tahqiq trial per week).
Quick
Short, direct answers with citations. No thinking trace. Best for quick fiqh lookups and verse references.
Example: "What is the time for Maghrib prayer?"
Reasoner
Balanced depth with visible thinking. Investigation trace, evidence map, chain-of-verification preview.
Example: "How do the four madhabs differ on wiping over socks?"
Deep
Extended investigation across multiple rounds. Full thinking trace; private mode (no cross-user signals).
Example: "Trace this hadith's authenticity through every collection that records it."
Tahqiq تحقيق
In-depth investigation with Chain-of-Verification on every citation. The deepest mode Theo has. Private by design.
Example: "Authenticate this isnad and explain any defects in the chain."
Plus users: one Tahqiq trial per week, free.

02

SEE IT IN ACTION
One hadith. Six investigation steps.
Click through what Theo actually does on a single question — "Actions are judged by intentions." Find the hadith across collections, walk the chain of narrators, weigh each narrator's reliability, check for hidden defects, and read the verdict. Every screen here is the same data Theo cites at chat.theogrid.ai.
Step 1 — The Hadith
إنما الأعمال بالنيات
Actions are judged by intentions, and every person shall have what they intended.

SIX GUARANTEES
What makes Theo different in practice.
01
Cited vs Considered
Every answer separates evidence Theo actually used in reasoning from evidence Theo looked at and set aside. Both are inspectable; nothing is hidden by omission.
02
Recall drawer
Any cited hadith opens to its full chain of narrators, grading rationale, and source-collection page reference — mid-conversation, without losing your place.
03
Insufficient-evidence frame
When the corpus does not contain enough to answer, Theo says so plainly and explains what additional sources would be needed — never fabricates to fill the gap.
04
Tahqiq is private
Your deep-investigation sessions never feed any model training, ours or third-party. Tahqiq™ mode runs in a session-private context that is not retained for training, fine-tuning, or evaluation.
05
Anonymous-first
Start asking without an account. The full free tier (15 questions a day) requires no sign-in, no email, no phone. An account is optional and unlocks memory, history, and longer sessions.
06
EBO, never fatwa
Theo produces Evidence-Based Opinions (EBOs) — structured analyses with evidence presented openly, reasoning visible, confidence calibrated, every source cited. Never a ruling. The scholar decides.
NINE WAYS THEO REMEMBERS
Personalized scholarship, on your terms.
Madhab preference
Hanafi · Maliki · Shafiʿi · Hanbali, or all schools side by side. Your answers lead with your school’s view and note where the others differ.
Knowledge level
Beginner · intermediate · advanced · scholar. Theo pitches its explanations, terminology and Arabic at your level.
Topical interests
Qurʾān and tafsir · hadith · fiqh · aqeedah · Islamic history · Arabic · spirituality · contemporary issues. Your starter questions follow what you care about.
Custom instructions
Tell Theo about yourself and how you like your answers — “I am new to Islam,” “keep it scholarly, with Qurʾān references.” Applied to every answer.
My Journey
See the subjects you have explored, set learning goals, and pick up where you left off.
Response length
Concise · balanced · detailed. Choose how much depth Theo gives you by default.

THE DIFFERENCE
They trained a model to chat. 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 hadith on the classical scale: Sahih, Hasan, Da'if
- Traces narrator chains and identifies weaknesses
EBO, never fatwa Theo produces Evidence-Based Opinions (EBOs) — structured analyses with evidence presented openly, reasoning visible, confidence calibrated, every source cited. Never a ruling. The scholar decides.
BUILT FOR HOW YOU PRACTICE
Theo speaks Muslim, not just Islam.
Generic AI products 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.
Five locale interfaces, native typography
English, Arabic, Urdu, Indonesian, Malay. Native script in each, right-to-left where the language demands it, calligraphic respect throughout. The way Muslims actually use the web.
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.
