Feature-by-feature
Writingmate is a broad AI workspace: it offers 600+ chat models including GPT-5.5, Claude Opus 5, Gemini 3.6 Flash, Grok 4.3, and DeepSeek V4 Pro, plus image generation (Nano Banana Pro, FLUX.2 Pro) and video generation (Sora 2, Veo 3.1, Seedance 2.0). You can upload files of any size, use web search with citations (Sonar Pro), build custom agents, and compare models side-by-side. RPLY (now NOX) is laser-focused on messaging: it unifies iMessage, WhatsApp, Slack, Telegram, Signal, Instagram, X, LinkedIn, Discord, and Email into one inbox. Its AI drafts replies in your voice and tone, and you can define Signature Patterns for common responses. RPLY also offers end-to-end encryption, local on-device message indexing, and an Inner Circle closeness graph. Writingmate's latest news (July 2026) adds Gemini 3.6 Flash and a developer API; RPLY's news (Dec 2024) upgrades AI to Claude Sonnet 4.5 and adds conversation filters. Both have free tiers, but writingmate caps free usage and costs $20/mo for reasonable daily limits (50 messages/day). RPLY's Pro unlocks unlimited conversation memory and search.
Pricing compared
Writingmate uses a freemium model: the free tier lets you test core features, but serious use requires the Pro plan at $20/month, which gives 50 chat messages per day, image/video generation, and file uploads. For heavier users, an Ultimate plan likely offers unlimited messages (check site). RPLY also starts free with basic features, then Pro subscription unlocks unlimited conversation memory and search. Exact Pro price isn't stated here, but it's likely a monthly or yearly fee. The key trade-off: Writingmate replaces multiple AI subscriptions (ChatGPT, Claude, Gemini), saving money if you'd otherwise pay $20+ each. RPLY replaces time spent on messaging—12 hours/week per user—so its value is more about productivity ROI than direct subscription cost. Both are affordable for professionals; Writingmate's $20 is a flat all-access fee, while RPLY's value is harder to quantify in dollars.
