The free confusion
Why "Claude Opus 4.6 free" searches feel misleading
Third-party mirrors are risky
Model aggregator sites promise free access but hide unclear limits, data practices, and unofficial wrappers. Tabbit is the official browser product.
Developer tools are overkill
Kilo Code and API workflows are built for engineers. Tabbit brings Claude Opus 4.6 to everyday power users through a native browser interface.
