Oncello

Helping you create higher quality documents faster with real-time
proof-reading and instant access to your firm’s knowledge—all within your existing workflow.

Oncello solves a familiar problem: Spending too much time proof-reading and looking for knowledge you already have.


We’ve lived that frustration. Finding and fixing what you need takes time, disrupts flow, and often leads to duplicated work.


Oncello bridges the gap between knowing and doing – so you spend less time searching and editing, and more time solving.

Critical insights are often scattered – across intranets, emails, precedents, and people’s heads.

“We’ve built entire teams around editing and document review—and yet, we’re still finding obvious mistakes that somehow survive five rounds of review.”

“It’s not the legal thinking that drains me. It’s spotting missing definitions, inconsistent capitalisations, and rogue commas after a 14-hour day.”

“There’s nothing like the joy of spending the morning fixing a definition that’s used five times but defined three different ways. It’s absurd.”

“Half my time goes into just finding the right wording I know we’ve used before. The other half is spent wondering why we don’t have a better system.”
