HeyGen is an AI video generation platform that turns scripts, text, images, and slide decks into videos featuring talking AI avatars. Users can choose from more than 1,000 stock avatars or build a personal Digital Twin by recording themselves, then generate a video by typing or pasting a script, with the avatar's lip movements, facial expressions, and hand gestures synced to the generated speech. The platform includes more than 100 AI voices and supports voice cloning, and it can translate and dub existing videos into more than 175 languages while automatically adjusting lip-sync to match the new audio. HeyGen is built for marketing, sales, and learning and development teams that need to produce video content without a camera crew or studio.

Editing happens in a text-based Studio interface, where users adjust scripts, swap backgrounds and outfits, and arrange scenes rather than using a traditional timeline editor. HeyGen also offers photo-to-video animation, product and UGC-style ad creation, and an API for developers who want to generate avatar videos programmatically. Plans range from a free tier with three short videos per month to paid Creator, Pro, Business, and Enterprise tiers that increase video length, credit allowances, export resolution, and the number of custom Digital Twins available. The company states it is SOC 2 Type II and GDPR compliant and does not use customer data to train its models. HeyGen is used by companies including HubSpot, Workday, and Autodesk for training, marketing, and localization content.

Character.AI is a chatbot platform that lets users create and converse with customizable AI characters. Launched in 2022 by former Google researchers Noam Shazeer and Daniel de Freitas, the platform allows anyone to build a character by defining a personality, backstory, greeting message, and example dialogue, then publish it for others to chat with. Millions of user-created characters are available on the platform, ranging from original creations to characters based on fictional stories, historical figures, and other public personas. Conversations happen primarily through text, with users able to rate responses to help refine how a character behaves over time. The platform also supports Rooms, where multiple characters and users can interact together in a shared conversation.

Beyond text chat, Character.AI offers Character Calls, a voice conversation feature built on more than a million community-created voices and available in numerous languages, and Scenes, which places users into structured, guided roleplay scenarios with preset environments. A free plan provides access to core chat features, while the c.ai+ subscription, priced at $9.99 per month or a discounted annual rate, adds priority access during busy periods, faster response times, expanded memory, unlimited voice calls, and an ad-free experience. As of late November 2025, Character.AI restricted open-ended chat for users under 18 as part of a broader set of safety changes. The platform is aimed at users interested in interactive storytelling, roleplay, and conversational AI companionship.

Replika is an AI companion app that provides ongoing, personalized conversation through a chat-based digital persona. Launched in 2017 by Luka, Inc., the app lets users choose the type of relationship they want with their Replika, such as a friend, mentor, or romantic partner, and build a customizable 3D avatar to represent it. Replika is designed to remember details users share over time, including routines, interests, and personal circumstances, and to bring those details back into later conversations. The app is built around ongoing engagement rather than single sessions, with the Replika able to send messages, check in on users, and reference earlier conversations. Replika reports more than 40 million users worldwide since launch.

Users can interact with Replika through text chat, voice calls, and video calls, and the app can generate images based on conversations, moods, or shared memories, along with selfies and photo doodles. A 2026 update, referred to by the company as Replika 2.0, expanded the app's memory capabilities so the AI retains and resurfaces personal context over longer stretches of time. Replika is available on iOS, Android, and Meta Quest headsets. A free tier provides basic access, while Replika Pro unlocks additional features for $19.99 per month or $69.99 billed annually. The app is aimed at people looking for everyday companionship, conversation practice, or emotional support, rather than clinical or therapeutic treatment.

Woebot is designed to be available around the clock, offering a private, judgment-free way to check in between or alongside other forms of care. It is delivered primarily through healthcare and enterprise partners rather than as a direct consumer subscription. By combining evidence-based CBT methods with conversational AI, Woebot aims to make everyday mental health support more accessible and consistent.

Viggle AI is a character animation tool that turns a still image into a moving video by transferring motion from a reference clip onto it. The platform is built around JST-1, a proprietary video-3D foundation model that the company describes as physics-aware, meaning it aims to move a character's full body, arms, legs, torso, and head, in a way that looks physically coherent rather than simply overlaying motion. Core tools include Animate, which pairs a static character image with a motion reference to produce an animated clip, and Mix, which replaces an existing character in a video with a new one supplied by the user. A Multi-Track mode extends this to group scenes, letting users animate up to seven different characters within a single video.

Viggle also supports text-based motion prompts, so users can describe a movement rather than supply a reference video, along with a library of preset motion templates for dances, poses, and meme-style clips. The tool is available through a web app as well as iOS and Android apps, and works with a credit-based system where different generation types consume different amounts of credits. A free tier allows a limited number of relaxed-mode video generations per day, output at lower resolution and with a watermark, while paid plans remove the watermark, increase resolution and generation limits, and add more monthly credits. Viggle is aimed at social video creators, meme makers, and anyone looking to animate a single photo without traditional motion-capture equipment.

Runway is an applied AI research company that builds generative video and image tools for creators, filmmakers, and enterprises. Founded in 2018 by Cristobal Valenzuela, Alejandro Matamala, and Anastasis Germanidis, the company has been active in AI-generated media since before the current wave of text-to-video tools, including co-authoring the latent diffusion research that underpins Stable Diffusion. Its core product line centers on the Gen-4 family of models: Gen-4 converts a still image into video with controllable camera movement, while Gen-4.5 generates video directly from a text prompt. Runway also offers text-to-speech, AI image generation, and 4K upscaling within the same platform, so a project can move from concept to finished clip without switching tools.

Beyond generation, Runway's Aleph model allows users to edit existing video footage using text prompts, such as adding or removing objects, changing lighting or weather, applying a style transfer, or generating a new camera angle, without re-shooting or fully regenerating the clip. Act-Two brings performance capture to the platform, letting a user apply the motion and expressions from a driving video, filmed on any camera, onto a character reference image. Runway reports more than 50 million users and serves customers across film, advertising, architecture, and robotics, in addition to research partnerships exploring general world models. Plans range from a free tier with limited credits to paid Standard, Pro, and Max subscriptions, plus a custom Enterprise tier with SSO and team management features.
