As answered by people managing ciferi and Diffyn.
ciferi's answer
Free browser-based audit calculators (materiality, sampling, going concern) that produce working-paper-ready output, paired with paid template packs built to specific ISA paragraph requirements. No login, no account, no trial period on the free tools.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
ciferi's answer
Enterprise platforms like CaseWare and TeamMate serve firms with five-figure budgets. Generic template marketplaces sell documents written by content marketers, not auditors. Ciferi's templates cite specific ISA paragraphs at the cell level, include pre-built cross-references between working papers, and follow the structure an AFM or FRC reviewer would expect to see in an audit file.
Diffyn's answer:
Diffyn is the platform that specializes on both change management and multi-model analysis.
ciferi's answer
Built on modern web infrastructure. The calculators run entirely in the browser with no data stored on our servers.
Diffyn's answer:
React, Next.js, POSTGRESQL
ciferi's answer
Audit managers and partners at non-Big 4 European firms. Mid-tier and SRA-member firms in the EU, UK practices regulated by the FRC, and German WPK-registered firms.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
ciferi's answer
Built by a practicing auditor who got tired of rebuilding the same working papers from scratch on every engagement. The free calculators came first because every auditor needs a materiality number and a sample size, and the existing options were either locked behind enterprise logins or built by people who've never touched an audit file. The template packs followed from the same problem at a larger scale.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
