Changelog

Labeled Descript's $24 Creator rate as annual billing for one person and showed the $35 monthly alternative. Identified the Make preset as an editable credits budget instead of a verified subscription quote. Added official pricing links and usage guidance. Preset totals are unchanged; this was a targeted review, not a complete subscription audit.

Replaced legacy Cursor Pro in the developer stack and tool finder with the current $30 monthly Premium plan. Explained separate third-party model charges and legacy subscriber plans. The developer template now totals $80 monthly before extra usage and tax. This was a targeted Cursor review; broader subscription verification remains incomplete.

Added Google's October 13 Gemini 4 Argon release to the model comparison and token estimator. Included introductory API prices through November 30, December 1 standard rates, thinking-token billing and the unified input/output context window. Other model verification dates retain their actual review scope.

Added Mistral Large 4 to the model comparison and token estimator with its public-preview status, 1M context window, promotional API rates and regular-price guidance. Kept Large 3 as a separate model. Labeled the stack calculator's $10 Notion Plus price as annual billing for one member. Provider-wide pricing and subscription reviews remain incomplete where source details could not be verified.

Added Claude Haiku 5.5 with its higher full-request rate above 100,000 input tokens. Updated Sonnet 5.5 cache-read guidance and replaced the deprecated Gemini 3.5 Flash token-counter option with Gemini 3.6 Flash at its current promotional rate. Provider sources were checked; the broader comparison review remains due for an inaccessible DeepSeek source and Mistral catalogue follow-up.

Stopped the music converter's initial setup from clearing a file selected while the page finishes loading. Changing conversion modes and carrying scores between tools still reset the appropriate state.

Connected the FPS, GPU tier, and resolution labels to their dropdowns so screen-reader users can identify each setting. Graphics recommendations are unchanged.

Removed universal percentage equivalents and the unsupported US GPA conversion. Added a worked GWA example, course-inclusion guidance, and UP Diliman sources. Clarified that an estimated GWA does not establish honors eligibility.

Added support for pasted rupee amounts with Indian or international comma grouping. Invalid and out-of-range amounts now show a clear error instead of blank wording or stale copy controls. Clarified input and cheque guidance.

Clarified that Gemini 2.5 Pro API access is limited to prior active users and linked Google's guidance for new projects. Rechecked provider pricing for the weekly AI comparison and cost-tool reviews; tracked prices remain unchanged.
