Magic Circle is TechTack's own domain-AI product: a secure AI-agent workspace for law firms and professional-services teams. Agents read across a matter's documents, answer with citations to the exact clause, and turn scanned files into searchable, AI-ready data — all inside enterprise-grade security.
Legal and professional teams were promised a lot by general AI — and burned by the two things that matter most in their world: it makes things up, and it isn't safe with confidential files. A hallucinated clause or a leaked diligence file isn't a glitch; it's malpractice.
In legal work, an answer you can't trace to a source is worthless — and an answer that leaks the file is worse. Magic Circle is built around both problems.
So TechTack built Magic Circle: domain AI where every finding is cited to the exact sentence it came from, and the whole system runs inside enterprise-grade isolation — no training on your data, ever.
The challenge
A legal team's value is locked inside documents — service agreements, amendments, NDAs, regulatory filings, diligence files, often as scanned PDFs that aren't even searchable. General-purpose AI either can't see those files safely, or answers confidently without showing its work.
To be usable in real legal and professional work, the product had to clear three bars at once: answers had to be verifiable (cited to source, not asserted), it had to read everything (including scanned images and tables), and it had to be confidential by construction — safe enough for privileged client material.
What Magic Circle does
Agents that work across a matter the way a careful associate would — and show their working.
Agents across your matters
Ask a question and agents decompose it, cross-reference every instrument in the matter at once — surfacing conflicts and inconsistencies across agreements, amendments, and NDAs in a single pass.
Cited to the exact source
Every finding links to the precise page and clause it came from. Click any citation to jump to the source passage and verify before signing off or delivering to a client.
Structured deliverables
Ask for a timeline, a clause comparison, or a risk summary and get Gantt charts, tables, and reports generated straight from the matter documents — not just prose.
Scanned documents, unlocked
An OCR engine extracts structured data from any document type — text, tables, charts, even construction drawings — so scanned images become searchable and AI-ready.
From matters to answers
The workflow a firm follows, from connecting its files to delivering a finished work product.
- 1
Set up your firm workspace
Provision an isolated tenant for the firm, with SSO, roles, and 2FA — confidential by default before any document is touched.
- 2
Bring your matter files
Connect enterprise repositories — Google Drive, Dropbox, iManage, SharePoint, and the web — so matter files come in from where they already live.
- 3
Index legal documents
OCR and indexing turn every file, including scanned images and tables, into searchable, structured, AI-ready data.
- 4
Run legal agents
Agents decompose the question, cross-reference instruments, and search legal sources across the whole matter at once.
- 5
Review with citations
Every finding is traceable to the exact clause — so a lawyer verifies, not just trusts, before sign-off.
- 6
Deliver in your format
Export the result as the timeline, table, memo, or report the matter actually calls for.
