Appinio vs simtrial: at a glance
What is Appinio?
Appinio is layering AI across the research workflow, from survey draft to reusable insight.
Appinio is steadily wrapping its survey platform in AI: importing drafts from any document format, generating sentiment and multi-question insights on results, and turning past studies into a queryable knowledge base. The non-AI work is polish — dark mode, white-labeled sharing, flexible KPI displays, richer significance testing — aimed at making the tool presentable to stakeholders. The shape is a research tool trying to compress the distance between fielding a survey and acting on it.
What is simtrial?
A fixed-design trial simulator grew a pluggable test framework, then spent a year proving the numbers
simtrial simulates time-to-event clinical trials and applies the tests used to analyse them — logrank, weighted logrank, MaxCombo, RMST, milestone. The 0.4.0 release turned it from a fixed-sample simulator into a group sequential one and standardised every test behind a common output contract, and the releases since have been about making that machinery correct and fast enough to run at scale. Version 1.0.0 arrived in June 2025 with the API settled and three vignettes explaining both the one-call and build-it-yourself paths.

◆ Current state
Appinio is steadily wrapping its survey platform in AI: importing drafts from any document format, generating sentiment and multi-question insights on results, and turning past studies into a queryable knowledge base. The non-AI work is polish — dark mode, white-labeled sharing, flexible KPI displays, richer significance testing — aimed at making the tool presentable to stakeholders. The shape is a research tool trying to compress the distance between fielding a survey and acting on it.
◆ Where it's heading
Direction is toward AI handling the tedious ends of research: setup and synthesis. The questionnaire importer removes data entry at the front; sentiment analysis and the cross-survey knowledge base remove manual reading at the back. If the knowledge base graduates from beta, Appinio shifts from a per-study tool toward an institutional research memory.
◆ Prediction
Expect the beta knowledge base to reach general availability and connect to the AI insights engine, so users query across all historical surveys rather than analyzing one at a time.

◆ Current state
simtrial simulates time-to-event clinical trials and applies the tests used to analyse them — logrank, weighted logrank, MaxCombo, RMST, milestone. The 0.4.0 release turned it from a fixed-sample simulator into a group sequential one and standardised every test behind a common output contract, and the releases since have been about making that machinery correct and fast enough to run at scale. Version 1.0.0 arrived in June 2025 with the API settled and three vignettes explaining both the one-call and build-it-yourself paths.
◆ Where it's heading
Post-1.0 the work is almost entirely statistical correctness and speed, and it is concentrated in sim_gs_n(): one-sided efficacy bounds, stratified targeted-event cut dates, a helper that derives cuttings straight from the design object. Performance moves in one direction throughout — dplyr replaced by data.table, foreach combination replaced by manual assembly, parallelisation added to sim_fixed_n() — because simulation-based operating characteristics are only useful if you can afford enough replications.
◆ Prediction
The recent fixes cluster on stratified and group sequential paths, so the next release most likely continues there rather than adding a new test type. The cut_from_design() helper suggests tighter coupling to gsDesign2 design objects is the direction of travel.
