AI-drafted. Human-reviewed. Guaranteed accurate.
Our proprietary process produces cover letter drafts grounded entirely in your case documents or other document sources — not generated from inference. Every draft is a time-saving foundation, not a finished product. You bring the legal arguments. We handle the rest.
Free to start. No credit card required.
No fabrication — guaranteed
Our proprietary extraction process grounds factual claims in your uploaded case documents. Where external sources are referenced — such as published standards, regulatory guidance, or third-party data — they are cited within the draft. Nothing is fabricated or presented without a traceable source. In the rare event that a material unsourced or inaccurate claim appears, we refund the full cost of the draft.
10–30 hours saved per petition
Attorneys using ImmiBlocks drafts report saving 10 to 30 hours per petition — time reallocated to legal strategy, not document assembly.
For law firms only
Our drafting service is available exclusively to immigration attorneys, law firms, or companies that work with attorneys. This protects the quality of work and ensures every draft is reviewed by a qualified professional before submission.
We addressed the problems other AI tools create.
WHY IS OUR PLATFORM BETTER THAN DIY AI?
Many firms are already experimenting with AI for cover letter drafting — and running into the same issue.
When a paralegal spends nearly half her time identifying inconsistencies (hallucinations) produced by a general-purpose AI platform, the time savings disappear before they reach the attorney. The problem isn't AI itself. It's that general-purpose tools weren't built for the precision immigration cover letters require.
ImmiBlocks was.
Our proprietary extraction process grounds every claim in your uploaded documents — eliminating the inconsistencies at the source, not after the fact.
A proprietary process built on strict extraction and layered checks.
HOW IT WORKS
1
Document upload
Your team uploads case files directly to the ImmiBlocks platform. The platform can read various file types, but does best with PDF files.
2
High-level or case-specific views
Our AI uses strict extraction protocols to pull factual information directly from the uploaded documents. Nothing is inferred or generated from outside the file. Legal arguments are intentionally omitted — that's your team's job.
3
AI self-check and error flagging
The AI reviews its own output, checking for internal inconsistencies and flagging any areas of uncertainty. Flags are passed forward — they don't disappear between steps.
4
Human review
An experienced writer reviews the draft — checking for accuracy, consistency, and structure. Our writers have backgrounds in legal writing, paralegal work, and immigration documentation, and are trained specifically for this process.
5
Delivery
The draft is delivered as an editable Word document, ready for paralegal refinement and attorney review. It is not a finished product — it is an accurate, well-structured foundation that saves your team significant time.
Once your case files are uploaded to ImmiBlocks, our process takes over. Here's how a draft moves from documents to your inbox.
Not a perfect letter — a reliable foundation.
ACCURACY
100%
refund if a material factual error appears
Error-free or it's free guarantee: Our proprietary extraction process grounds factual claims in your uploaded case documents. Where external sources are referenced — such as published standards, regulatory guidance, or third-party data — they are cited within the draft. Nothing is fabricated or presented without a traceable source. In the rare event that a material unsourced or inaccurate claim appears, we refund the full cost of the draft.
We don't promise a zero percent error rate.
We promise a process rigorous enough that errors are rare — and a guarantee that backs it up. Every cover letter must be reviewed by a writer before submission. That's not a disclaimer; it's the intended workflow.
Choose the draft that fits your workflow.
