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 Sleeknote?
Sleeknote wires leads straight into CleverReach as its holiday push continues
Sleeknote has shipped eight items in a month ahead of Black Friday: Game Studio (beta) with nine mini games, single-use codes for Spin to Win and Scratch to Win, Seasonal Calendars with per-day analytics and easier setup, full-screen campaigns, and connectors that let Claude, ChatGPT, Cursor and Grok answer campaign questions. The newest is a native CleverReach integration that sends collected leads to CleverReach lists without CSV exports or middleware.

Hunter's prospecting stack now runs inside ChatGPT, Claude and Gemini, not only its own app.
◆ 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.

Sleeknote wires leads straight into CleverReach as its holiday push continues
◆ Current state
Sleeknote has shipped eight items in a month ahead of Black Friday: Game Studio (beta) with nine mini games, single-use codes for Spin to Win and Scratch to Win, Seasonal Calendars with per-day analytics and easier setup, full-screen campaigns, and connectors that let Claude, ChatGPT, Cursor and Grok answer campaign questions. The newest is a native CleverReach integration that sends collected leads to CleverReach lists without CSV exports or middleware.
◆ Where it's heading
The holiday work centers on gamified, time-boxed campaigns and measuring them, while the CleverReach connector extends the other end of the funnel: getting captured leads into email tools without glue. Integrations and analytics both point at proving campaign value to ecommerce marketers.
◆ Prediction
Expect more seasonal calendar and template tweaks through December, and possibly further native email-platform integrations in the same format as CleverReach.
