Avatar SDK by Itseez3D turns a single selfie into a recognizable, fully rigged 3D avatar โ realistic or cartoon, head or full-body. Create avatars in the browser with the MetaPerson Creator, embed it via iframe + JS API, or integrate native SDKs for Unity, Unreal Engine, iOS, Android and Web โ plus a headless Cloud API for server-side generation at scale. Every avatar is fully rigged with facial blendshapes and a Mixamo-compatible skeleton, and exports to standard GLB/glTF and FBX (Unity, Unreal, Blender, three.js, Babylon.js). Customize face, body shape, haircuts, outfits and accessories. Deploy in the cloud or on-premise with Local Compute. Built by Itseez3D since 2014; used in games, VR/AR, virtual try-on and virtual identity.
ForthWrite is an AI email writing assistant for Gmail and Outlook that learns your writing style from your real sent mail. The more you use it, the more it sounds like you. Get smart drafts in seconds, auto-draft replies before you open your inbox, and maintain your personal voice at scale. Free to start, no credit card required. Works inside Gmail and Outlook on the web.
How it works
ForthWrite captures your tone, sentence rhythm, and sign-offs from your actual sent emails, then uses that profile to generate drafts that match how you write, not a generic AI voice. Every draft you edit or send improves the model over time.
Key features
Who uses it
Professionals who send high volumes of relationship-critical email: lawyers, financial advisors, recruiters, account executives, founders, and anyone who wants their inbox handled without sounding like a chatbot wrote it.
Pricing
Free tier includes 10 drafts per week with no credit card required. Paid plans start at $12/month and include unlimited drafts, custom persona prompts, and auto-draft.

Avatar SDK's answer
Avatar SDK is built by Itseez3D, founded in 2014 and headquartered in Santa Clara, California, by engineers with deep roots in computer vision and the OpenCV community. The company started with 3D face and body scanning and evolved into a platform that reconstructs recognizable, fully rigged 3D avatars from a single photo. Today it powers avatar creation across games, VR/AR, e-commerce/virtual try-on and virtual-identity products, offered as an embeddable creator (MetaPerson), SDKs, and a Cloud API.
ForthWrite's answer:
Built out of frustration with AI writing tools that produce text that sounds nothing like the person sending it, and as a way to handle large amounts of daily email. The core insight was that your sent mail is the best training data you already have, and no tool was using it.
Avatar SDK's answer
Computer vision and deep learning for photo-to-3D reconstruction; a 3D graphics pipeline that outputs rigged meshes with facial blendshapes and a Mixamo-compatible skeleton; standard 3D formats (GLB/glTF and FBX); and delivery through SDKs for Unity, Unreal Engine, iOS, Android and Web plus a Cloud REST API. On the web, avatars integrate with three.js and Babylon.js, and Local Compute enables on-premise/offline generation.

Avatar SDK's answer
Avatar SDK turns a single selfie into a fully rigged 3D avatar โ head or full-body, realistic or cartoon โ and delivers it three ways: an embeddable browser-based creator (MetaPerson), native SDKs for Unity, Unreal Engine, iOS, Android and Web, and a headless Cloud REST API for server-side generation. Every avatar has facial blendshapes and a Mixamo-compatible skeleton and exports to standard GLB/glTF and FBX, so it loads into Unity, Unreal, Blender, three.js and Babylon.js with no conversion. It runs in the cloud or fully on-premise/offline via Local Compute.
ForthWrite's answer:
ForthWrite learns your writing style from your actual sent mail, not a generic prompt. Every draft sounds like you wrote it because it was trained on how you actually write. It also auto-drafts replies before you open your inbox, so your email is partially handled before your day starts.
Avatar SDK's answer
Avatar SDK combines production-ready avatar quality with unusual flexibility in integration and deployment. Unlike cloud-only tools, it can run fully on-premise/offline via Local Compute, and it exports open GLB/glTF and FBX with no lock-in. It offers both an end-user creator you can embed and a headless Cloud API for automated pipelines, plus native SDKs for Unity, Unreal, iOS, Android and Web. It's built by Itseez3D, an independent company shipping avatar technology since 2014 โ and after Ready Player Me shut down in 2026, it became one of the main production-ready migration paths.
ForthWrite's answer:
Most AI email tools give you a blank box and a "write for me" button. ForthWrite builds a voice profile from your sent history and gets more accurate with every draft you edit or send. Unlike ChatGPT or Gemini, it works natively inside Gmail and Outlook with no copy-paste. Unlike Lavender, it writes the draft, not just scores it.
Avatar SDK's answer
Developers and enterprises adding avatars to their products โ game studios, VR/AR apps, e-commerce and virtual try-on, metaverse and virtual-identity platforms, and marketing teams. It serves indie and mid-size developers through the Pro plan and the embeddable MetaPerson creator, and larger companies through the Enterprise Cloud API and on-premise Local Compute. The common thread: teams that need recognizable, rigged 3D avatars from a photo without building the pipeline themselves.
ForthWrite's answer:
Professionals who send high volumes of relationship-critical email and cannot afford to sound generic: lawyers, financial advisors, recruiters, account executives, consultants, and founders managing their own inbox.
I built ForthWrite because I kept sending emails that sounded like they came from the same generic AI as everyone else. After launching it, I still use it for my own inbox every day, which is about the most honest endorsement I can give.
The Chrome extension lives inside Gmail and Outlook on the web. Open a thread, hit Alt+Shift+D, and a draft comes back in your voice, not a template. The free tier is real: 10 drafts per week, no API key, no credit card. Voice matching is included on free, because that is the point.
What keeps it useful compared to Gemini or a chat tab: it learns from what you actually send. Every edit you make before hitting send becomes a signal. Over time the drafts drift closer to how you really write, and the dashboard shows the improvement curve so you can see it happening.
The web compose surface lets you draft from forthwrite.ai without installing anything, useful for people who want to try before committing to the extension.
Standard adds recipient-aware and intent-aware drafting plus AI coaching. Pro adds auto-draft (replies waiting when you open Gmail), batch replies, and Prompt Lab for version-controlling your prompts. Teams adds a shared persona and seat-level analytics.
ForthWrite is not for everyone. If you just need quick replies and tone does not matter, Gemini is free and already in your inbox. ForthWrite is for people where tone does matter: client communication, relationship-driven threads, external correspondence where sounding off costs something real.
Disclosure: I am the founder and use it daily. Happy to answer questions in the comments.
