Roo Code
Roo Code's visible releases are CLI point versions aimed at driving the agent from a script.
A side-by-side editorial comparison of Khoj and Character.AI — release velocity, themes, recent moves, and the top alternatives to consider.
Khoj gave its assistant long-term memory, then started winding down its own cloud.
The 2.0 beta line is doing two things at once. In February it gave Khoj long-term memories, moving the assistant from per-conversation context to knowledge that persists across sessions. Six weeks later it began deprecating Khoj cloud — a banner warning hosted users, and the subscribe option removed from the web app's settings page. The same release upgraded the web app to Next.js 15 and fixed the research agent stopping earlier than it should.
Character.ai keeps building outward from chat into worlds, video, and creator tooling
Character.ai is expanding well beyond one-on-one chat into a full creation-and-entertainment platform. In quick succession it has shipped Lorebook (structured world knowledge for Characters), studio-produced vertical microdramas ((c.ai) series), a creator feature bundle, and deeper memory. The company is treating user-generated Characters as the seed of a broader interactive-media catalog.

Khoj is consolidating around the self-hosted product and the model layer beneath it, and stepping back from running the hosted service. Model support has been broadening steadily — Gemini Pro 3, Minimax M2, Nano Banana image editing, configurable fallback models with admin-set priority — while Stability AI image generation was dropped. The client work follows the same logic: Obsidian batch sync, file query filter autocomplete, reference copying, all aimed at people running their own instance against their own files.
With subscriptions already disabled and a deprecation banner live, the next step for the hosted service is a shutdown date. The entries stop in late March 2026, so whether 2.0 has left beta since is not visible here.

The company is treating user-generated Characters as the seed of a broader interactive-media catalog.
Two prongs are clear: deepen the creation surface (Lorebook, memory, creator tools) so Characters become richer and stickier, and add first-party content formats (series, playable books, Imagine visuals) to drive engagement beyond text. This is a bid to become an entertainment platform, not just a chatbot, with creators as the supply side.
Expect Lorebook to graduate from beta toward all users and to connect with memory as a grounding layer, plus more studio-led video building on (c.ai) series.
