Writitude (formerly Textok) vs Gnbly

Writitude (formerly Textok) is a brand voice and writing guidelines platform built by copywriters in Riga, Latvia. It turns tone and style rules into automated checks that run in real time as writers draft copy, whether the text comes from a freelancer, an in-house marketer, or an external AI tool.

The product centers on configurable writing guides with 100+ parameters covering formality, emotionality, rhythm, inclusivity, capitalization, and emoji usage. You can build guides with a wizard, generate them from sample texts via Guide Builder, or match existing copy to predefined tones with Matcher. Custom glossaries enforce required terms, forbidden words, and exact spelling for brand-specific vocabulary.

Writitude targets lean marketing teams, agencies managing multiple client voices, and growing brands that need consistent communication across channels. The platform shares guides with writers, flags off-brand passages instantly, and claims to cut revision cycles by 60% compared to manual editing rounds.

Gnbly is an automation studio that builds AI-native software for go-to-market, content, and operations teams. The company ships three products on a shared AI fabric: NatterGPT for voice agents, Vidsue for long-form video production, and WorkerFleet for operational automation. Each tool runs on the same models, memory layer, and security stack.

Compared with buying separate point solutions, Gnbly bundles focused products that share infrastructure. You trade a single-vendor suite for deeper cross-product memory, but each product still has its own site and pricing rather than one unified dashboard.

Gnbly targets operators at growth-stage companies who want voice, video, and workflow automation without building custom agent infrastructure. NatterGPT handles outbound and inbound calls with copilot mode, Vidsue turns scripts into publish-ready videos, and the studio reports 12M+ agent actions monthly across 40+ countries.
