Shortwave

Shortwave is an AI-powered email client built by former Google engineers that layers natural-language automation on top of email. Users can ask it to organize their inbox, draft messages in their own voice, search across past mail, and schedule meetings, all through plain-language prompts rather than manual filters. Beyond individual productivity, Shortwave includes team features such as shared threads, comments and assignments, plus integrations with Slack, Notion, Asana and HubSpot. It is used by teams at companies including Twilio, Spotify and GitHub, and runs on Mac, Windows, iOS and Android in addition to the web.

Grammarly

Grammarly is an AI writing assistant that checks grammar, spelling, punctuation, and style in real time across browsers, desktop apps, and mobile keyboards. It integrates directly into Gmail, Google Docs, Microsoft Word, Slack, and thousands of other websites via a browser extension. Beyond basic correctness, Grammarly analyzes tone and clarity, suggesting rewrites to make writing more concise, confident, or friendly depending on the context and audience selected by the user. GrammarlyGO adds generative AI features for drafting emails, replying to messages, and rewriting passages on demand, while Grammarly Business adds brand style guides and analytics for teams that need consistent written communication across an organization.

AISA

AISA is a conversational AI skills assessment platform that helps professionals measure, prove, and improve their AI fluency. Instead of answering multiple-choice questions, users have a real back-and-forth conversation with Aisa, an adaptive AI assessment agent that adjusts to the user's skill level and profession. The experience is designed to feel like a natural dialogue while capturing concrete evidence of AI capability across multiple dimensions. The platform scores users across five dimensions — Prompting & Communication, Critical Thinking, Technical Understanding, Workflow Integration, and Safety — broken into 11 specific criteria, each evaluated against a fixed, validated rubric refined over more than 1,500 sessions. After a 20-40 minute conversation, users receive a detailed report card showing their AI persona, dimension scores, and overall fluency level, with the report generated in about three minutes. AISA positions AI fluency as a higher stage than AI literacy: fluency means AI is deeply embedded in how you work. The platform also offers a free, verifiable AI Skills Certificate that can be added to LinkedIn with one click, making it useful for career development, workforce upskilling, and organizational benchmarking. Optional paid tools include a self-paced AI Fluency Map, an AI coach on WhatsApp, and human-supported coaching for those who want to improve their scores.

Vocal Image

Vocal Image is an AI-powered voice and communication coach that helps people speak with more confidence, clarity, and presence. Users record short voice exercises and receive instant feedback on pitch, clarity, pace, and confidence. The app then builds a personalized daily training plan with articulation drills, intonation practice, public speaking scenarios, and accent work. With more than four million users and 8.4 million voice tests taken, it is positioned as a practical daily gym for communication skills rather than a lecture-style course. Inside the app, the coaching experience is built around short, interactive exercises. The AI Roleplay module lets users practice high-stakes conversations such as job interviews, salary negotiations, and first dates with an AI character that talks back and scores the interaction. The Articulation Trainer turns tongue twisters into scored games with leaderboards, while the intonation visualizer uses pitch-curve matching to help users sound more expressive. Breathing exercises, video coaching shorts, and the community-driven Voice Arena round out the training experience. Vocal Image is designed for anyone who wants to improve their speaking voice, from professionals preparing for meetings and presentations to non-native English speakers working on accent clarity. The app also offers specialized programs for speech recovery after a stroke and voice masculinization or feminization, making it useful for rehabilitation and LGBTQ+ voice alignment goals. Available on iOS, Android, and the web, the service combines AI feedback, structured practice, and measurable progress through re-tests and side-by-side recordings.

Character.AI

Character.AI lets users converse with AI-driven characters that have distinct personalities, or build and publish their own characters for others to chat with. Conversations can be text or voice-based, and the platform supports group chats mixing multiple AI characters and human participants in the same thread.
