Platform

One workspace for research, review, and drafting

Four tools that share the same matter, the same sources, and the same permissions. Start with one and add the rest when your team is ready.

  • Research

    Research with citations

    Ask a question about a contract, a statute, or a whole data room. Every sentence in the answer links to the passage it came from.

    ResearchAvenmore Foods, supply review

    Can the buyer end the supply agreement if deliveries are late three months in a row?

    Yes, but only after notice and a chance to fix it.

    The buyer may terminate for repeated late delivery, which the agreement defines as three or more late deliveries in any rolling six-month period. It must first give written notice and allow the supplier 30 days to cure. Orders shipped before termination stay payable.

  • Review

    Document review at volume

    Run the same checklist across thousands of documents. Solon flags unusual clauses and missing terms, and puts the reason next to each flag.

  • Drafting

    Drafting in your style

    Get a first version of a memo, a clause, or a letter that follows your firm's templates, defined terms, and house style.

  • Precedent

    Knowledge vault

    Search your firm's own precedent by meaning, not file name. Find the clause you negotiated last year and the matter it came from.

How it works

From a pile of documents to an answer you can stand behind

Solon works on the files you already have. No new filing system, and no long training course.

  1. 01

    Bring in the matter

    Connect your document system or drop in a data room. Solon reads PDFs, scans, emails, and spreadsheets, and keeps the folder structure you already use.

    214 files indexed

  2. 02

    Ask in plain language

    Type the question the way you would ask a colleague. Narrow it to one document, a folder, or the whole matter.

    Answer ready, 2 sources

  3. 03

    Check every answer against its source

    Click any citation to open the exact passage, highlighted on its page. If a claim has no source, Solon says so instead of guessing.

    Citation matches the page

FAQ

Questions legal teams ask before they start

  • Every sentence in an answer links to the passage it relies on, so a lawyer can check it in one click. When the documents do not support a claim, Solon says it could not find a source rather than filling the gap. Answers are a starting point for a lawyer's review, not a replacement for it.
