Daiah (Chabad.AI)
The Chassidus library and AI study assistant from the Chabad publishers, public at chabad.ai since October 15, 2026. What it covers, what it costs, where it falls short, and how it compares with NotebookLM and ChatGPT.
On this page
Daiah is an AI study assistant that answers questions about Chassidus from a library of the Rebbeim's seforim and shows the source for each point. It lives at chabad.ai. The older address, daiah.org, now forwards there.
Most AI tools guess at a Likkutei Sichos reference from memory. Daiah searches texts the publishers supplied and lets you tap a citation to read the original words. That is why the group started using it for "where does the Rebbe say this?" questions in 2026.
Who runs it
Chabad.AI launched publicly on October 15, 2026 (4 Cheshvan 5787), timed to the fiftieth anniversary of the Rebbe's 4 Cheshvan 5737 farbrengen about technology and hafatzas hamaayanos. Launch coverage on COLlive and Anash.org describes it as a joint project of four publishers:
- Kehot Publication Society
- Vaad Hanachos B'Lahak
- Chabad.org
- Sichos In English (SIE), the managing operator
The site's Terms of Use name Sichos In English as the operator of "Chabad.AI, including the Daiah library and assistant."
What it costs
There is a free plan. As of October 21, 2026, the pricing page lists:
| Plan | Price | AI credits per month | Notes |
|---|---|---|---|
| Free | $0 | 125 | Full library access; free credits are also capped per 5-hour session |
| Personal | $12/month | 300 | |
| Family | $20/month | 600, shared | Up to 6 family members, each with a profile |
| Scholar | $50/month | 1,300 | Not slowed during peak usage; priority support |
Credits are for AI answers; each answer uses a few, depending on its length. When credits run out, new questions wait for the next reset. Every plan, including Free, lists full library access. Payments go through Stripe and paid plans can be canceled anytime. Prices and allowances can change, so check the pricing page before you recommend a plan to someone.
The library page asked for sign-in when ChabadLabs checked on October 21, 2026, so plan on making an account. The Terms set a minimum age of 13; under-18s use it through a family plan a parent manages.
What is in the library
The publishers describe the library as "a vast collection of seforim in their original Hebrew, alongside many English translations and adaptations." No full title list is public without signing in. Once signed in, the sidebar's Library page shows what is loaded. Beta testers in July 2026 reported new seforim arriving every few days.
On October 16, 2026, a member who went through the Library page posted the gaps he found. These are one member's notes from launch week, so check the Library page yourself:
- Only some volumes of the Alter Rebbe's and the Mitteler Rebbe's maamarim, five volumes of Or Hatorah, and partial sets for the Rebbe Maharash, the Rebbe Rashab and the Frierdiker Rebbe.
- Toras Menachem from Tishrei 5711 through 5729, plus 5751 volume one.
- Later years (5737 onward) only through Sichos In English adaptations, and no Sichos Kodesh.
- Igros Kodesh present. One heavy user said Daiah's Igros coverage is the main thing the shared Rebbe's Torah notebook in NotebookLM lacks.
What it does well
Reports from the group, July to October 2026:
- Exact citations. In a September 2026 head-to-head, one member found every Likkutei Sichos source Daiah gave was right down to the volume and section. The same question in NotebookLM returned footnotes pointing to the wrong sichos.
- Tap to source. Each citation opens the original words, so checking a claim takes seconds.
- Igros for life questions. A shliach facing a hard personal decision asked Daiah and got a set of relevant letters from the Rebbe, which he said gave him clarity.
- Sharing. You can share a conversation by link; the person who opens it gets a copy to continue.
- Speed for simple lookups. "Narrow guardrails, excellent for simple lookup," as one tester put it during the beta.
Where it falls short
Also from the group, with dates:
- Short answers on deep questions. On "Was Avraham upset at the Akeidah?" (September 2026), one member felt Daiah's short answer ("no doubts or negative feelings") flattened the sugya, while NotebookLM gave a fuller picture of anguish and joy together. Others in the same thread preferred Daiah.
- Named people and topics. The Rebbe often did not name the people or events he spoke about, so a search by name can miss the sicha. One member could not find a well-known sicha about illness that ChatGPT located at once.
- Ma'anos without the question. Answers to letters sometimes come without the question the Rebbe was answering, which changes how you read them.
- Rate limiting. Scrolling very fast through a sefer locked one member out for a while (October 18, 2026).
- No connector yet. Members asked for an app and an MCP connector so Daiah can be used inside Claude or ChatGPT. The launch coverage says "more to come in the weeks and months ahead" but announced neither.
- Hebrew and English toggle. One user's confusion turned out to be Chrome's auto-translate. Turn it off for chabad.ai.
The Terms say it plainly: "AI answers can be wrong... Always check the cited sources yourself." The Terms also say Daiah's answers are not a halachic ruling and not an official position of the publishers.
Copying is blocked
The reader does not let you copy text. Pasting shows a notice that the text is copyright-protected and that reuse needs written permission. The Terms allow reading, searching and studying, and sharing "individual answers and short excerpts with their source citations for personal, educational, and non-commercial purposes." They do not allow copying, downloading or scraping the library, republishing it, or using it to train or build another AI tool. The Terms also say Chabad.AI does not use your conversations to train AI models.
The copy block set off a long debate in the builders' group in September 2026. See Chassidus Copyright and Access for the positions on each side.
Daiah, NotebookLM or ChatGPT?
NotebookLM was renamed Gemini Notebook in July 2026; the group still mostly calls it NotebookLM. The table mixes checked facts (cost, copying) with the group's test results from September and October 2026.
| Daiah (chabad.ai) | NotebookLM with the Rebbe's Torah notebook | ChatGPT or Claude on their own | |
|---|---|---|---|
| Where the text comes from | Publisher-supplied text | PDFs a member uploaded | The model's memory and web search |
| Citations | Tap to the original words | Footnotes; members found some point to the wrong sicha | Often invented; verify every one |
| Igros Kodesh | Yes | Not in the shared notebook | Unreliable |
| Depth on a hard question | Can be brief | Often fuller | Fluent, not grounded |
| Copy text out | Blocked | Yes, from your own sources | Yes |
| Cost | Free plan; paid from $12/month | Free | Free tier or your plan |
The October 15 launch thread argued over whether a frontier model will always beat an in-house system like this. One side: "The frontier will always do better than an inhouse system with RAG." The other: most seforim are not available to any general AI, so a model that cannot read the text cannot cite it. A third view landed in between: Daiah likely has more of the text, ChatGPT is the faster and stronger model, and Daiah will have to keep up with model upgrades.
A practical split many members settled on: Daiah to find the source, the sefer to read it, and a general assistant to help shape a class around text you paste in yourself.
Using it well
- Ask for the source first, then the explanation: "Where does the Rebbe discuss X? List each place with volume and page."
- Tap every citation before you quote it. Read a few lines before and after.
- For a letter, look for the question being answered before you apply the answer.
- If a search by name fails, search by the idea or the parsha instead.
- If you rely on it for avodah questions, one builder's advice from October 2026 holds: an AI chavrusa does not replace your mashpia.
History
- March 2026: In the builders' group, members connected to SIE described an AI and text platform for Chabad seforim in development, to open first to a small group of testers.
- July 2026: A closed beta opened at daiah.org. Testers saw footnotes in a sidebar, a feedback button, and copy-paste disabled.
- September 2026: Heavy users called it "the best for Chassidus, by far" for finding sichos and maamarim, and the copy-block debate ran for several days.
- October 15, 2026: Public launch at chabad.ai with free and paid plans.
