Paritok vs Prompt Bridge: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Paritok and Prompt Bridge — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
P
Paritok
Paritok
Non-destructive compression gateway that drops between coding agents and LLMs to cut input tokens by up to 85% without changing the agent.
Key features
- Drop-In Gateway: One environment variable (ANTHROPIC_BASE_URL) reroutes your agent through Paritok — no agent, prompt, or tool changes.
- Tool Schema Compression: 46-schema tool blocks (~29K tokens) drop to ~8K per turn by keeping relevant tools and stubbing the rest, frozen per conversation for cache stability.
- Code-Native 4B Model: A 4B compression model trained on 45K real agent trajectories keeps identifiers, paths, and errors while shrinking file reads and outputs to ~26% of original.
- read_original Recall: Every compressed segment is tagged; the agent asks read_original(ref) and gets the exact bytes locally without spending an extra turn.
- Stale History Summarization: Turns beyond a configurable recent window get summarized once when your context budget fills, so recent turns stay pristine and overflows drop to zero.
- Multi-Agent Compatibility: Works today with Claude Code, Cursor, Codex, OpenHands, and any OpenAI-compatible upstream — Anthropic and OpenAI both supported.
- Compounding Savings: Saved share grows across a session — 25% at 1 turn, 54% at 10 turns, 63% at 20 turns — against a 96,500-token baseline.
- Open Weights and Benchmark: SWE-bench Lite floor of 86.5% quality retained at 25.7% compression rate, with weights and training pipeline published.
Best for
- MCP-Heavy Workflows: Cut input bills for agents that ship 70+ MCP tool schemas on every turn.
- Long Coding Sessions: Run 3× longer coding-agent sessions before context saturation forces a hard compact.
- Bill Reduction: Estimate 54% off input tokens on a 5-developer team at 20-turn Claude Sonnet sessions (~$6,550/year).
- Self-Hosted Privacy: Route agent traffic through your own hardware with no data leaving your network — 8GB GPU is enough.
- Enterprise Cost Governance: Add compression at the gateway layer so all coding agents on the team benefit without engineering per-agent.
- Cursor/Codex/Claude Code Fleet: Standardize compression across a mixed toolchain of coding agents behind one gateway.
Prompt Bridge
Prompt Bridge
Free Chrome extension that captures your AI chat context and injects it into any other AI platform in one click.
Key features
- One-Click Capture: Save the full conversation from ChatGPT, Claude, Gemini, Grok, Copilot or DeepSeek with a single button.
- Smart Compression: An AI summarizer condenses long chats into tight context blocks, cutting token cost when re-injecting.
- Instant Bridge Inject: Paste your saved context into any other AI's input box in one click, without manual copy-paste.
- Auto Platform Detection: Recognizes the active AI site on tab switch and adjusts capture/inject actions without setup.
- Local-Only Storage: Conversations are kept on your device — no servers, no cloud sync, no telemetry.
- Multi-Browser Support: Ships as a Chrome Web Store extension and works on Chrome, Edge and Brave.
- Zero Sign-Up: Installs and runs without an account or configuration.
Best for
- Cross-Platform Research: Continue a long ChatGPT thread inside Claude or Gemini without losing the accumulated context.
- Model Comparison: Feed the same conversation into different LLMs to compare answers on identical setups.
- Token Cost Reduction: Compress a long chat before re-injecting so you don't pay to replay the full history.
- Privacy-Conscious Workflows: Move sensitive discussions between AIs while keeping the transcript exclusively on-device.
- Team Handoffs: Share a compressed context block with a teammate so they can pick up an AI conversation from a fresh session.
- Multi-Model Coding Loops: Draft with one model, refine with another, and let context travel along instead of re-typing.
