FOR CONTEXT
Most platforms now ship some built-in AI. It is worth being precise about where that stops, because it is the gap every control on this page is built to fill.
| Built-in AI | Rana AI Mentor | |
|---|---|---|
| What it does | Four generic one-shot actions: summarise, explain, generate text, generate image. | Thirteen purpose-built controls, including coaching, roleplay, graded practice and voice. |
| Where it lives | Inside the editor toolbar. The reader never sees it — only the author does. | Embedded in the page itself, so the end user interacts with it directly. |
| Conversation | One shot. No memory, no follow-up, no back-and-forth. | Multi-turn where it matters, with threaded context across turns. |
| Grounding | Works on whatever text you selected, and nothing else. | Reads the page, a pasted document, a URL, or your own database. |
| Choice of model | Whatever the vendor wired in. Usually one model, not disclosed. | Routed per request to the cheapest model that clears the quality bar for that task. |
| Cost visibility | None. Consumption is invisible until the invoice. | Model, tokens in and out, and the cost of each call, shown on demand. |
| Spend control | Usually a flat per-seat licence, with no per-user or per-team limits. | Budget caps by company, department and individual, enforced before the call is made. |
| Quality assurance | None. A poor answer costs the same as a good one. | Every answer graded; a failing answer is retried on a stronger model and not billed. |
The two are not mutually exclusive — they run side by side happily, and seeing them next to each other is usually the fastest way to feel the difference.
