Stetbot: Sentence-Level Essay Grading and Feedback

Stetbot is an AI-powered tool designed to help students and educators grade essays, code, and lab reports against custom rubrics before submission. It functions similarly to a Teaching Assistant, analyzing text sentence by sentence to identify gaps, errors, and strengths. This tool ensures that every claim is annotated and every missing point is named, giving users a clear picture of their performance.

Benefits

Stetbot offers several key advantages for anyone needing to evaluate written work. It provides sentence-level annotation, meaning every single sentence receives a specific score. Users can hover over underlines to see exactly what is strong, weak, or missing, rather than receiving only a summary at the end. The tool supports custom rubrics, allowing users to paste any existing rubric or build one using a structured editor. It accepts text from various formats, including direct pasting or file drops. Users can also toggle between encouraging, neutral, and strict feedback tones to suit their needs. Additionally, the tool provides a live preview of the graded essay with detailed notes on every sentence. For educators, the Pro version allows for bulk grading of an entire class by pasting, dropping files, or importing a CSV.

Use Cases

Stetbot is useful for students who want to improve their writing before submitting assignments. It can be used to grade essays, code, or lab reports against specific criteria. Educators can use it to quickly grade large volumes of student work in a single session. The tool is also helpful for anyone who needs to track their progress over time, as every grading session is saved to the user's account. This feature allows users to revisit past drafts and see how their scores improve. It works well for argumentative essays, technical reports, or any document that requires detailed feedback on structure, evidence, and mechanics.

Pricing

Stetbot offers a simple pricing model with two plans. The Free Plan costs $0 forever and requires no credit card. It includes 8 gradings per week. The Pro Plan costs $5 per month and includes everything needed with no limits. Users can start for free and upgrade when they need more capacity. No credit card is required to begin using the free tier.

Vibes

Users appreciate the detailed feedback provided by Stetbot. The sentence-level scoring helps people understand exactly where they stand on specific criteria like thesis, evidence, structure, voice, and mechanics. The ability to choose between encouraging, neutral, and strict tones makes the tool adaptable for different situations. The live preview feature is praised for making the grading process transparent and easy to follow. Many users find the bulk grading feature for educators to be a time-saver when managing large classes.
