In their own words
LegalOn
LegalOn is a web and extension platform for everyday in-house legal work, covering contract intake, review, drafting, and matter information. Its AI flags contract risks, creates redlines, and applies positions from playbooks. LegalOn Assistant answers legal questions, summarizes agreements, drafts fallback language, and surfaces insights across contracts and matters. More than 135 attorney-built playbooks cover common commercial contracts, and custom playbooks are supported. Vault extracts obligations, dates, counterparties, and risk terms from contract portfolios for search. Matter Management centralizes intake and triage, tracks owners and deadlines, and shows workload visibility. Connections include Microsoft Word, email, Slack, and Microsoft Teams. LegalOn lists SOC 2 Type II, ISO/IEC 27001:2022, and ISO/IEC 27017:2015 certifications, encryption in transit and at rest, and no use of customer data to train third-party foundational models. Pricing is on request, with a 14-day trial and no free plan.
TaxCalc
TaxCalc is a UK accounting software platform for tax compliance, client management, and practice operations. Its products prepare personal, partnership, trust, and company tax returns, as well as statutory accounts. For Self Assessment, SimpleStep guides users through relevant sections, with an option to switch to HMRC-style forms. Calculations update in real time, and Check & Finish reviews a return before submission. Tax products submit directly to HMRC, while Accounts Production files statutory accounts to Companies House. Accounts Production can import year-end trial balances from Xero, QuickBooks, or FreeAgent and export journals and adjustments; integrations differ between products. TaxCalc supports self-employment and investment income, but does not include state filing. It runs on Linux, macOS, and Windows, with mobile access limited to the web. Pricing is paid, from £42, with a free trial and no free plan. TaxCalc says each licence includes unlimited weekday phone and email support from UK-based, accountancy-trained specialists.
