Legal software that shows its sources, not its guesses

Law firms run on documents, deadlines, and trust. We build AI and platforms that answer from your own files with citations, and we keep them running in production.

In short

Reactll builds software for law firms and legal teams: AI question-and-answer over your own documents and contracts that always cites its sources, secure client and matter portals, and intake automation. Answers respect who is asking and say plainly when the files do not contain them. Reactll engineers these systems and keeps them running in production — not just in a demo.

For legal, AI Systems leads — specifically retrieval over your own documents where every answer shows its sources, respects who is asking, and says plainly when the files do not contain the answer. Product Engineering and Modernize & Operate back it up when the tool you need does not exist yet or an ageing practice-management system is holding the firm back. We build these systems and keep running them in production — not a demo, not a pilot that quietly dies.

What you get

1

Answers you can check

Every response links back to the exact document and passage it came from, so your team verifies in seconds instead of taking the software's word for it.

2

Nothing invented

When the answer is not in your files, the system says so instead of guessing. Access follows who is asking, so confidential matters stay confidential.

3

Built and kept running

We do not hand over a prototype and leave. We engineer the system, ship it, and operate it in production so it still works next quarter.

Questions, answered straight

Yes. We build retrieval over your own documents so your team can ask plain-language questions and get answers drawn from your files. Each answer cites the source passage so it can be verified quickly.
Every answer shows the exact documents and passages it is based on, and the system is built to say plainly when the information is not in your files rather than guessing. Verification stays with your lawyers, where it belongs.
Yes. We build intake and triage workflows that collect information, route it, and assemble documents, with a human reviewing before anything is finalised. It reduces manual handling without removing professional judgment.
We design for confidentiality, with access that respects who is asking so matters are only visible to the right people. Hosting and data-residency choices are agreed with your firm and built to fit your requirements.
No. These are tools that help your team find, check, and organise information faster. They do not practise law or provide legal advice — professional judgment and client responsibility remain entirely with your lawyers.
We do. Reactll has run software in production since 2018, so we do not just build and disappear — we operate, monitor, and improve the system so it keeps working as your firm and its documents grow.
