About Synterrix

Synterrix is a Google Sheets add-on that pushes AI work into the spreadsheet where a lot of operations, sales and e-commerce data already lives. Its distinguishing feature against the many GPT-for-Sheets clones is fine-tuning: you assemble training examples in a sheet, train a task-specific model on them, and then call that model from a cell — which gets you consistent, house-style output on a narrow repetitive task without engineering a long prompt for every edge case. Models can be improved with more examples over time and deployed outside Sheets as well. Around that sit the bulk primitives. Prompts execute at scale with built-in API load management, so thousands of rows run from one command rather than tripping rate limits. AI autocomplete uses few-shot prompting to infer a repetitive task from two or three filled-in examples, with a context field and headers for extra rules. Image URLs process in bulk for descriptions, categorisation or product copy. Google Search grounding injects live context into prompts for research and enrichment. And a scraper extracts text from URLs and Google Docs, targeting specific HTML elements by ID or class or pulling SEO metadata, across thousands of pages at once. Over sixty pre-built templates ship with it. Pricing is per user per month with a monthly character allowance, and — the important part for heavy users — unlimited usage when you supply your own API key.
