What is Hunter.io?
Hunter's prospecting stack now runs inside ChatGPT, Claude and Gemini, not only its own app.
Hunter spent the first half of 2026 owning the send: domains, inboxes, warm-up, sequences and recipient-based reporting. The latest batch puts that stack where the user already works. A ChatGPT app with 30+ tools is included on every plan, including Free; Claude, Gemini and Perplexity get native setups; and other clients connect through a hosted MCP server. Discover also flags new matches on saved searches and pre-selects them.
What is Single Grain?
Single Grain's feed shifts to sales-ops how-tos, still agency content rather than product.
The Single Grain feed remains agency blog content, not a changelog. The November 4 evening batch, four posts in under an hour, covers AI-native companies, measuring AI ROI, AI visibility reports as lead magnets and testing an AI Overview opt-out, after a November 3 batch on sales ops and AI agent monitoring.

◆ Current state
Hunter spent the first half of 2026 owning the send: domains, inboxes, warm-up, sequences and recipient-based reporting. The latest batch puts that stack where the user already works. A ChatGPT app with 30+ tools is included on every plan, including Free; Claude, Gemini and Perplexity get native setups; and other clients connect through a hosted MCP server. Discover also flags new matches on saved searches and pre-selects them.
◆ Where it's heading
The loop of find, send, protect and measure is still the product, but the front door is moving. A user can go from a plain-language request to a prepared sequence without opening Hunter, which leaves data and deliverability as the parts Hunter owns while the interface passes to the assistant. Saved-search alerts fit that shift, since Discover now brings work to the user instead of waiting for a query.
◆ Prediction
Expect the Prompts library and the MCP tool set to grow, along with more Discover signals delivered as ready-to-work lists. The entries do not show whether assistant usage will change credit pricing; existing limits and credits apply for now.

5.0MARKETING
Single Grain's feed shifts to sales-ops how-tos, still agency content rather than product.
◆ Current state
The Single Grain feed remains agency blog content, not a changelog. The November 4 evening batch, four posts in under an hour, covers AI-native companies, measuring AI ROI, AI visibility reports as lead magnets and testing an AI Overview opt-out, after a November 3 batch on sales ops and AI agent monitoring.
◆ Where it's heading
Posts keep arriving in same-day batches and lean on AI-assisted marketing and sales operations. There is still no product, so nothing in the feed changes what a user can do.
◆ Prediction
More batched how-to posts on AI-assisted marketing and sales are likely; the feed gives no sign of a product release.
