CrbonFree vs DokBot: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of CrbonFree and DokBot — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
CrbonFree
Crbon Labs Inc.
CrbonFree meters the energy and carbon of every AI token across providers, with published factors, uncertainty bands and audit-ready retirement receipts.
Key features
- Per-Token Carbon Metering: Counts every token by model and provider and converts it to energy, CO2e and water using versioned, published factors.
- Multi-Provider Coverage: Connects OpenAI, Anthropic, OpenRouter, AWS Bedrock, Google Vertex AI, Azure Foundry, Vercel and Cloudflare AI Gateways into one report.
- Many Ingestion Surfaces: Read-only provider keys, TypeScript and Python SDKs, an OAuth-secured remote MCP server, a CLI for local coding agents and a Chrome/Edge extension for ChatGPT, Gemini and Claude.
- Layered Methodology with Uncertainty: Reports model energy, data-centre overhead and embodied hardware/training carbon separately, each with a ±28.3% uncertainty band.
- Metadata-Only Privacy: Receives only model, token counts and timestamps — prompt and completion content never leaves your systems.
- Signed Retirement Receipts: Paid plans issue receipts listing credit serial numbers on the American Carbon Registry or BCarbon Registry, publicly verifiable.
- Monthly Audit Packs: Zip exports with a manifest hash plus badges and certificates to back published climate claims.
- Dashboard & REST API: One view of tokens, cost and carbon across projects with CSV/JSON export and twelve read endpoints with an OpenAPI spec.
Best for
- Scope 3 Reporting: Sustainability teams produce defensible AI emissions figures for disclosures instead of spend-based guesses.
- Engineering Carbon Visibility: Track the footprint of coding agents like Claude Code across a dev team via the CLI.
- Model Selection by Footprint: Compare energy and carbon per provider and model tier when choosing models for production workloads.
- Carbon Offsetting with Proof: Retire credits against measured AI usage and share verifiable receipts with auditors or customers.
- Board and Auditor Requests: Hand auditors monthly audit packs with verifiable hashes when asked for AI emissions data.
- Personal Chat Usage Tracking: Individuals estimate the footprint of their ChatGPT, Gemini and Claude sessions with the browser extension.
DokBot
DokBot
DokBot turns your PDFs and documents into an embeddable RAG support chatbot for your website in minutes, using your own API key or built-in credits.
Key features
- Multi-Format RAG Knowledge Bases: Native ingestion of PDF, DOCX, XLSX, MD and TXT files with automatic processing and chunking — no copy-pasting text.
- Bring Your Own API Key: Connect OpenAI, Anthropic, Google AI Studio, Groq, OpenRouter, CheaperInference or Ollama Cloud directly without a middleman.
- Managed AI Credits: Optionally buy monthly AI credits so DokBot runs the model on its own provider key and bots need no API key.
- Human Handoff: When the bot doesn't know an answer it collects the visitor's email and surfaces the full conversation in the Conversations inbox.
- Shadow DOM Embeddable Widget: Install with one script tag before </body>, fully isolated so it never breaks your site's CSS.
- Live Preview Testing: Iterate on prompts and verify answer accuracy in a live preview before going public.
- MCP Access: Pro plan exposes MCP so your own AI assistant can manage bots and knowledge bases.
Best for
- Website Customer Support: Answer common visitor questions 24/7 from product manuals and help docs.
- Documentation Assistant: Let users query long technical PDFs or guides conversationally instead of searching manually.
- Lead Capture from Unanswered Questions: Collect emails when the bot can't answer and follow up with full context.
- Low-Cost Support Automation: Small businesses run a support bot on free-tier or cheap model providers via BYOK.
- Multilingual SMB Support: Spanish-speaking businesses deploy a docs-grounded assistant on their site in minutes.
- Agency Client Bots: Build and manage multiple bots with separate knowledge bases for different client sites.
