3.9 out of 5
Scored by a Toolio reviewer after real useOur verdict
Text Assistant works on whatever you select in the browser: get an explanation, run a grammar and spelling check, or turn the text into a chart, all using OpenAI's models behind the scenes. It's a simple, single-purpose utility rather than a full writing suite, aimed at quick one-off requests. Nothing runs until you enter your own OpenAI API key in the settings, and with no ratings yet its reliability is untested.
✓What it does well

Grammar and spelling checksProofreads selected text for grammar and spelling issues.
Text-to-chart generationTurns selected text into a generated chart.
✕Where it falls short
Bring your own API keyIt only works after you enter your own OpenAI API key.
No ratings yetThere are no ratings on record, so reliability is unproven.
Minimal feature setIt offers a basic, fixed set of actions rather than open-ended chat.
