evidence / 100
+ The broadest feature set in one place: Deep Research, code-executing data analysis on uploaded spreadsheets, voice mode and a huge library of custom GPTs.
− Free and Plus tiers hit message caps on the best models at busy times, and answers can be confidently wrong without citations unless you ask it to search.
+ Lets you choose the model per task and run bulk prompts over whole ranges with cost estimates up front.
− Requires understanding model pricing, and large jobs can hit rate limits or time out.
+ Ask a question in plain English and get the chart, the statistical test and the code that produced it.
− Free messages are limited and it can silently misread column meanings in messy spreadsheets.
All 5, side by side

|---|---|---|---|---|
| ChatGPT | 74 | Free tier | Plus $20/mo, Pro $200/mo | web, mac, windows, ios, android, api |
| GPT for Work | 8 | Free tier | Pay-as-you-go by model usage | web |
| Julius AI | 8 | Free tier | no limits published | web |
 Numerous.ai | 8 | Free tier | no limits published | web |
 Rows | 8 | Free tier | no limits published | web |
A free tier counts, and so does an open-source licence you can self-host — both are in the table, so a tool that is only free for a trial is not here.
