Use tool ↗About Signal87 AI
Signal87 AI is a document-intelligence workspace for legal, policy and government-contract teams that need answers drawn only from their own files. You upload contracts, reports, PDFs, Word files and spreadsheets, ask questions in plain language, and each answer links back to the page and paragraph it came from; it can also compare documents side by side and compute figures from spreadsheets. It now sells self-serve plans priced by document count after a short free trial with no card, and still runs government pilots. The company was founded in 2025 in Boston, with Michael Benezra as chief executive.

Pros & cons of Signal87 AI
Signal87 leans hard on traceability: every answer is supposed to link back to a specific page and paragraph in your own documents, which matters for legal and government-contract work where an unsupported answer is a liability. It has moved from sales-only to flat self-serve plans at $20 and $50 a month, so a small team can now test it on a real document set; the vendor is still young, founded in 2025, with little independent track record.
Pros
- Every answer ties back to a page- and paragraph-level citation in the source document
- Handles mixed formats, including PDFs, Word, Excel and scanned files, in one vault
- Flat self-serve pricing, $20 for 100 documents or $50 unlimited, with no per-question metering
- Five-day free trial with no card required
Cons
- Founded in 2025, so there is little independent track record to check
- The 100-document cap on the cheaper plan is tight for a real contract archive
- No public API found for wiring it into other systems
Best for
- Government contractors and legal teams that need citation-backed answers across large document vaults
- Small teams wanting flat-priced document Q&A over contracts and reports without a sales call
- Anyone comparing clauses or figures across many agreements at once
Not for
- Casual users who only need to summarise the odd PDF now and then
- Buyers who need a long vendor track record or published security certifications before uploading files
Watch out: The trial is only five days; load a representative document set on day one or the window closes before you can judge citation quality.
