OpenGamma

A private AI presentation tool. Your browser encrypts your documents and swaps names, amounts and dates for placeholders before anything reaches the AI. The real values are filled back in on your machine, and you download a native .pptx with editable text and charts.

How it works

• You review first. You see the placeholder version before the AI does.
• Two privacy modes. Masked mode keeps the wording and hides the values. Blind mode shares only structure and trends.
• On-brand by default. Import a brand kit from your PowerPoint template and colours, fonts, logos and tone of voice are applied. Off-brand choices are blocked.
• Works where you work. Use it with Claude, ChatGPT, or any app that supports MCP connectors.

Built for

Board and investor updates, client pitches and quarterly business reviews, finance and FP&A reviews, and people and HR reviews.

Security

Documents are encrypted in the browser with AES-256-GCM. The servers store only ciphertext, and the vault key is protected by your passphrase and a downloadable recovery key.

Pricing

A free plan covers one brand kit and 3 decks a month. The Core plan is $4.99 a month or $49 a year. New accounts get 30 days of Core free, with no card required.
