ChatGPT is a general-purpose assistant. It's powerful in the moment but starts from zero every session: you paste in your context, your metrics, and your prior updates every time. Briefer is an AI coworker built specifically for investor relations: it maintains persistent memory of your company, connects to your data sources, and handles approval and delivery end-to-end.

Common questions
- Can I just use ChatGPT for investor updates?
- You can, and many founders do. The friction is that ChatGPT starts from zero each session: you re-paste your metrics, prior update, and context every time. For founders sending monthly updates, that friction adds up fast. Briefer eliminates it by maintaining a persistent structured memory of your company.
- How is Briefer different from a ChatGPT custom GPT?
- A custom GPT can carry instructions but not live data, and it still needs you to paste in fresh numbers each session. Briefer connects directly to Stripe, HubSpot, your CRM, and your accounting system, so data flows in automatically. Briefer also handles the approval and delivery flow end-to-end, not just drafting.
- Is Briefer built on GPT?
- No. Briefer runs on Anthropic's Claude models, routed by task, with Cohere for search embeddings. What matters more than the model is the structured memory layer around it, which is what makes updates compound in quality.
- Is my data used to train ChatGPT or other models?
- No. Briefer's infrastructure contract with model providers explicitly excludes training use, and customer data is strictly tenant-isolated at the database privilege level.
