SEC 02TWO MODES · ONE WORKSPACE

Two intelligent workspaces

Legal AI and Accountant AI share one case-centric shell. Each mode brings its own templates, labels and agent policies, so the experience stays consistent while the work stays specialised.

SEC 03SEQUENCE · 4 STEPS

How LexSalim works

A case moves through four stages. The AI helps at every stage, and a person signs off at the end of each one.

  1. Step 01CASE-NEW

    Create a case

    Open a legal matter or an accounting engagement. Pick a template, set the jurisdiction and invite only the people who should see it.

    TEMPLATES · PERMISSIONS · JURISDICTION

  2. Step 02DOC-IN

    Upload documents

    Add letters, contracts, statements, receipts and exhibits. Each file is stored in the case vault with its version history.

    ENCRYPTED VAULT · VERSIONS · PROVENANCE

  3. Step 03AI-RUN

    Request AI analysis

    Ask the Case Agent to summarise, extract, compare or research. It works only on the case you are in, and only when you ask.

    CASE-SCOPED · ON REQUEST · LOGGED

  4. Step 04REVIEW

    Review findings and next steps

    Read cited findings, check the timeline and accept, edit or reject proposed actions. Nothing is relied on without your review.

    CITED · PROPOSED · HUMAN-APPROVED

SEC 04PRODUCT PREVIEW · SYNTHETIC DATA

Your case workspace

A single place for each matter: overview, documents, timeline, tasks and a Case Agent that only sees this case. The screen below is an illustration built with demonstration data.

ACase overview
Status, next deadline and last activity at the top. What changed, what matters, what needs approval.
BDocument vault
Every file stays inside its case, encrypted at rest, with versions and processing state visible.
CChronological timeline
Events, documents, agent findings and deadlines in one ordered record.
DTasks and deadlines
Open work, due dates and items waiting for your approval.
ECase Agent
Ask questions about this case. Answers cite the documents they rely on and wait for your review.
SEC 05ONE AGENT PER CASE

Dedicated AI agents

Each case has its own AI assistant. It knows that matter and nothing else, works from the documents you give it, and hands its findings back to you for review.

  • CAP-01Core

    Document analysis

    Summaries, key terms, dates, parties and amounts drawn from the files in the case.

  • CAP-02Core

    Case-specific questions

    Ask about this matter in plain language. The agent answers from the case, not from the internet.

  • CAP-03Planned

    Research assistance

    Context from approved sources, clearly separated from your private documents.

  • CAP-04Core

    Draft preparation

    Letters, notes, schedules and summaries prepared as drafts for you to edit.

  • CAP-05Core

    Source-linked findings

    Each finding references the document, page or source it relies on.

  • CAP-06Core

    Human review

    Findings and drafts wait for your approval. Nothing leaves the case without you.

Operating boundaries
  1. AutonomousPlanned

    Research of approved public sources

    Planned: agents may monitor and read authorised public sources on a schedule, and report what changed.

  2. On requestCore

    Processing of your private case documents

    Your documents are analysed only when you ask, inside the case they belong to, with the action logged.

  3. NeverBy design

    Sending correspondence or deciding for you

    Agents do not send letters or emails, file anything, or make professional judgements. They prepare; people decide.

// Every agent action is attributed, time-stamped and visible in the case timeline.

Case Agents in detail
SEC 06PLANNED CAPABILITY

Legal research intelligence

A planned research engine that reads only authorised sources, verifies what it finds and builds a cited knowledge library your Case Agent can draw on.

PlannedReleased per jurisdictionLicensed sources only
  1. STG-1

    Sources

    Approved public sources only: legislation, case law and guidance with permitted terms of use.

  2. STG-2

    Research agents

    Read, index and summarise new material from those sources on a schedule.

  3. STG-3

    Verification

    Citations are checked against the original text. Unverifiable items are flagged, not published.

  4. STG-4

    Knowledge library

    A curated, versioned library per jurisdiction, with provenance for every entry.

  5. STG-5

    Case research

    Your Case Agent draws on the library when you ask, and cites it alongside your documents.

Available in the workspace design
  • ▸ Questions answered from your own case documents, with page references
  • ▸ Document summaries, extractions and comparisons
  • ▸ Timelines, tasks and drafts prepared for review
Planned, released after verification
  • ▸ Scheduled research across approved public legal sources
  • ▸ Verified, versioned knowledge library per jurisdiction
  • ▸ Library citations alongside your documents in Case Agent answers

SEC 08CONTROLS · AS DESIGNED

Security and control

Legal and financial matters are sensitive. These are the controls LexSalim is built around. They describe the platform's design, not an external certification.

  • SEC-01

    Encrypted document storage

    Documents are encrypted at rest and in transit. Keys are managed separately from the files they protect.

  • SEC-02

    Case-specific permissions

    Access is granted per case, not per organisation. Members see only the cases they are invited to.

  • SEC-03

    Audit trails

    Uploads, views, agent actions and approvals are recorded with who, what and when.

  • SEC-04

    Human approval

    Agent findings and drafts are proposals until a person approves them.

  • SEC-05

    Source references

    Findings carry references to the documents or sources they rely on, so they can be checked.

  • SEC-06

    Privacy-conscious processing

    Case content is processed for your case only. It is not used to train shared models.

// Hosting region, sub-processors and data-processing terms are published with the service documentation at launch. No regulatory approval or certification is claimed.
