Everything you need to know about Textiva
Q.Does Textiva upload or store my text on any server?
Never. Textiva is engineered with a strict client-side first architecture. All tokenization, case conversion, diffing, extraction, and regex evaluations run entirely in your local browser memory. No text or documents are ever transmitted to our servers or third parties.
Q.Are these tools powered by generative AI or chatbots?
No. Textiva is a deterministic text utility platform. Every calculation, statistic, comparison, and formatting transformation runs on pure mathematical, linguistic, and algorithmic rules. You receive predictable, reproducible outputs without hallucinations.
Q.Can I process large documents and long texts?
Yes. Our engines are optimized for high-throughput string operations, supporting documents from small snippets to several megabytes. For heavy computations like Myers LCS side-by-side diffing, our algorithms feature memory guards and debounced execution.
Q.Is Textiva completely free to use?
Yes. All 290+ tools are 100% free with no account creation, no paywalls, no usage credits, and no telemetry of your confidential writing.
Q.How does Google Analytics work on Textiva?
Our Google Analytics 4 integration tracks only general page visits and anonymous tool access counts. Tool inputs, outputs, extracted credentials, URLs, and sensitive strings are strictly quarantined and never included in analytics payloads.
