Neocortex in depth

Read the full write-up

Neocortex is a character-authoring and integration platform for interactive software. It is strongest for developers who need to shape agent behavior as well as connect it to a game engine or service. Its broad toolkit is appealing, but credit and project caps—and restrictions on commercial use—make plan choice central.

Overview

A browser-based visual editor lets creators build personalities, conversation flows, and world dynamics. Its node-based editor adds rules for character features and interactions with other characters and environments, which is useful when behavior design matters as much as dialogue. The feature set includes action systems, spatial awareness, knowledge bases, emotional responses, and multilingual communication.

Neocortex targets smart NPCs, AI companions, virtual assistants, VR, voice-controlled games, education and training, and interactive storytelling. That breadth makes it more compelling for interactive experiences than for a project needing only voice generation. The Web API covers chat, streaming chat, session history, speech, streaming speech, transcription, quizzes, account and usage information, and character listing.

Key features

Visual and node-based authoring: Build characters, flows, and interaction rules in a web interface. This gives behavior designers a visual workflow, while the plan caps on characters and flows limit how much a project can contain.

Engine integrations and API: SDKs are available for Unity, Unreal Engine, and Godot, alongside a Web API usable from any engine or platform. The API’s range suits teams connecting agent behavior to a larger interactive system. Unity integration requires a Neocortex account, Unity 6 (6000.0) or later, and Git.

Speech and character capabilities: Speech, streaming speech, transcription, and custom voices sit alongside spatial awareness, emotional responses, and knowledge bases. This combination serves interactive characters; it is a less direct fit for conventional narration or standalone voiceover.

Privacy and deployment: Neocortex uses access controls and encryption, and encrypts transmission routes for particularly sensitive personal data. Its privacy policy describes rights to access, correct, delete, object to, restrict, and port data, and withdraw consent, subject to applicable law. Data may be processed or stored globally, with safeguards such as EU standard contractual clauses for certain transfers. Self-hosted and private infrastructure deployment are offered on Custom.

Pricing

Neocortex has a free plan and paid plans priced monthly, with annual billing amounts shown for the paid tiers. Free includes 2 characters, 2 conversation flows, 200 monthly credits, 1 API key, and 1 knowledge-base file upload. It is for personal use only and includes community support. The low cap makes it best for trying a small personal project, not commercial work.

Starter costs €9 a month, billed €108 yearly. It raises the allowance to 5 characters, 5 flows, 2,000 monthly credits, 3 API keys, and 5 knowledge-base uploads, with email support. Personal and academic use are permitted, but commercial use is not. It is a modest step up for small noncommercial projects, not a way to launch a paid product.

Pro costs €29 a month, billed €348 yearly. It includes 20 characters and flows, 10,000 monthly credits, multi-NPC group chat, 10 API keys, 20 knowledge-base uploads, and 5 custom voices. Commercial use is allowed and support is by email. This is the entry point for commercial projects, though its quotas still make usage planning important.

Team costs €99 a month, billed €1188 yearly. It adds 5 team seats, 100 characters and flows, 40,000 monthly credits, multi-NPC group chat, 50 API keys, 100 knowledge-base uploads, 20 custom voices, commercial use, and priority support. The higher caps and seats make it the clearer fit for a multi-person project with greater usage, but the price is a substantial jump from Pro.

Custom has custom pricing and offers unlimited characters and usage, custom software and app development, roadmap and SDK customization, enterprise data ownership and compliance, self-hosted and private infrastructure deployment, and dedicated partnership with priority support. It suits organizations with deployment or customization requirements beyond the standard tiers.

Platforms

Neocortex supports Android, iOS, Linux, macOS, Windows, web, API, and self-hosted use. The range gives teams several integration and deployment paths, while the Unity SDK’s stated requirement for Unity 6 (6000.0) or later rules out older Unity projects.

Who it's for

Choose Neocortex when a project needs configurable characters, interaction rules, and engine or API integration in one toolkit. Game developers, simulation teams, and creators of training or storytelling experiences can make use of its visual authoring and broad character features. It is not the right choice for commercial work on Free or Starter, or for a small project that only needs voice generation.

Pros and cons

Pro: Visual authoring, game-engine SDKs, and a broad Web API serve both behavior design and integration.

Pro: Pro and Team include commercial use, while Team adds 5 seats, higher quotas, and priority support.

Con: Free and Starter prohibit commercial use, so commercial creators must start at Pro.

Con: Monthly credits and limits on characters, flows, API keys, uploads, and custom voices constrain the standard tiers.

Con: Unity users need Unity 6 or later and Git, adding prerequisites for projects on older setups.

Alternatives

Game Voice Generators is a category directory for comparing tools in that area. For a broader creative platform, Adobe Firefly offers a free plan with limited daily generations and supports Android, API, iOS, and web. Altered Studio has a free tier with 3 min/month Voice Morphing, 10,000 AI Tokens, and local voice cloning under an attribution license with noncommercial use restrictions; it is a more voice-focused alternative.

Algebras AI Game Localization Agent is a more specific alternative for game localization, with a free tier and a Standard plan at $15 a month. AnnoMotion is another free-tier option, with credits and generators noted for its entry plan. For a focused text-to-speech API, Google Cloud Text-to-Speech offers free monthly character allowances for some voice plans.

Kokoro TTS is a free alternative with Apache-licensed open-weight model and self-hosted support. LOVO AI offers a free tier with 5 projects and paid plans with project or voice-hour allowances. Speechify offers a free plan with 10 voices and a 1.5x maximum speed, and a Premium plan at $29 a month.

Verdict

Neocortex is a strong choice for developers building interactive characters who want visual behavior authoring alongside engine SDKs and a broad API. Its main advantage is the combination of character systems and integration options; its main drawback is that commercial use starts at Pro, with quotas still governing scale. Choose it when those capabilities belong together in your project; look elsewhere for a dedicated voice tool or a commercial entry tier below Pro.

Verdict

Neocortex offers visual tools, game-engine SDKs, and a broad Web API for interactive agents and worlds. Check plan usage rights and quotas against the intended project before choosing a tier.
