Where we win.

Where they win.

Moving from Sapling.
Sapling users who came for the detection feature and stayed for the bundle often find AI Checker more accurate for the detection workload alone. If you primarily use Sapling for grammar and writing assistance, keep Sapling and add AI Checker as a focused detection layer.
AI Checker or Sapling — which fits you?
Sapling is a writing assistant — its core product helps teams polish prose with grammar checking, autocomplete, and tone suggestions. AI detection was added as an adjacent feature, not the foundation. This shows in product depth: Sapling's detection is good for surface-level checks but lacks the model identification, sentence-level analytical features, and API access that purpose-built detection products provide. AI Checker is detection-first — it's all we do, and we do it deeply. For teams that need writing assistance plus detection in one tool, Sapling makes sense. For teams that need detection done with full analytical depth (sentence-level highlights, model fingerprinting, perplexity exposure), AI Checker is the focused alternative. Many of our users run both: Sapling for editing, AI Checker for the final detection check before publication.
