Slack
Truffle is an AI teammate that answers plain-English questions about your codebase, in Slack. Connect your repos, docs and APIs once, then anyone (support, PM, sales, success — not just engineers) can @-mention Truffle and ask how something works. It answers in plain English and cites its sources, so you can trust it. No commands, no setup, nothing to learn. Free for one user with your own AI key, or $49/mo for the whole team. Stop routing every "how does this work?" question through engineers.

Messaging
Build one customer-facing AI agent and launch it across SMS, iMessage, WhatsApp, Slack, Telegram, and email. Give it your knowledge, memory, voice, tools, and boundaries so it can answer questions, use business systems, complete work, and hand off when human judgment is needed. Keiki runs the shared infrastructure behind every channel and gives you one place to inspect conversations, approve sensitive actions, and improve the agent over time.

Most AI support tools ask you to rip out your helpdesk first. Ify works on top of Freshdesk, Zendesk, Salesforce, or HubSpot and gets to work across email, chat, WhatsApp, Slack, and more. The part that usually stalls an AI support rollout is "our docs aren't good enough." Ify solves that by building its own knowledge base: it scrapes your site and docs, generates SOPs from release notes and past ticket resolutions. Built for support teams who want something live now.
