OpenAI 2026 hackathon

Tang

Tang lets you bring one or more sessions (or entire histories from the same tool) from Codex, OpenCode or Grok Build (at launch) directly into your active session. Keep the blade, switch the handle.

Executive Summary

What the company appears to be

Tang, as described by its author, is a workflow tool that allows users to connect sessions from multiple AI coding tools (Codex, Grok Build, OpenCode) into a single active session. It enables switching between different AI agents while preserving work history and offering visual tracking of connections.

What changed

The project began during a hackathon as an experiment in interoperability across AI coding platforms. The author describes it as a "skill and workflow" that starts with Codex but can pull together sessions from other tools. It was built in a short timeframe, with the author noting challenges around session storage differences between tools.

Single most important open question

Is there any evidence of user adoption or traction beyond the hackathon context? The description provides no data on usage, customers, revenue, or product-market fit beyond self-reported claims.

What The Product Actually Is

The description states:

  • Tang is a "skill and a workflow" that begins with Codex.
  • It allows users to bring sessions from other tools like Grok Build or OpenCode into an active session.
  • It supports connecting multiple sessions into one, or transferring between different AI coding environments.
  • It prints a "graphic multiverse loom style path of your connections."

Inference This implies a tool for managing and linking AI-generated work across platforms, potentially to avoid losing progress when switching tools.

Not evidenced No details on how the product functions technically beyond the author’s workflow process. No screenshots, UI elements, or functional demonstrations are provided.

Positioning & Claim Evolution

The description states:

  • The inspiration came from a failed session in Codex, where work was lost and difficult to recover.
  • The core idea is to avoid "valuable work trapped inside the handle that created it."
  • It positions itself as a way to keep the "blade" (the AI tool) while switching the "handle" (the platform).

Inference This suggests a positioning around interoperability and continuity of work across AI coding tools, with an emphasis on avoiding data loss or fragmentation.

Not evidenced No claims about market demand, competitive differentiation, or long-term vision beyond the hackathon prototype. The author does not describe any prior product iteration or user feedback.

Target Customer & ICP

The description states:

  • Tang is built for developers or users working with AI coding tools like Codex, Grok Build, and OpenCode.
  • It supports workflows involving multiple tools and agents.

Inference It appears aimed at developers who use more than one AI coding tool and want to maintain continuity of their work.

Not evidenced No explicit customer personas, user segments, or buyer profiles are described. No evidence of target market size, usage patterns, or feedback from actual users.

Business Model & Pricing Evidence

The description states:

  • The author intends to release Tang "always free like skills should be."
  • It is not described as a paid product or service at this stage.

Inference The project appears to be in an early prototype phase, with no commercial model yet defined.

Not evidenced No pricing strategy, monetization plans, or revenue streams are mentioned. No indication of whether the tool will ever be monetized.

Technical & Delivery Signals

The description states:

  • Built using Codex, Grok, OpenCode, and Sol.
  • Planning was done with Sol Ultra to create specs.
  • Code review was done in OpenCode.
  • Sessions were broken into "Beads" and looped through epics.
  • Challenges included differences in harness storage modes between tools.

Inference The tool is built on a stack of AI coding platforms, with a structured development process involving planning, testing, and iteration.

Not evidenced No technical architecture details, scalability assumptions, or delivery timelines beyond the hackathon context are provided. No mention of APIs, integrations, or backend systems.

Back to contents

Traction & Maturity Signals

The description states:

  • It works, as demonstrated by the author’s ability to continue sessions across tools.
  • It prints a visual "multiverse loom style path" of connections.
  • The author is proud of its functionality and compatibility with multiple tools.

Inference The tool has basic functionality and was completed within a hackathon timeframe.

Not evidenced No evidence of user adoption, retention, or usage metrics. No data on customer feedback, product iterations, or market response beyond the author’s own account.

Back to contents

Competitive Context

The description states:

  • It works with Codex, Grok Build, OpenCode, and Sol.
  • The author mentions Cursor as a potential future target for V2.

Inference It operates in the space of AI coding tools and session management, potentially competing with or complementing platforms like Cursor, Codex, and others.

Not evidenced No competitive analysis, market positioning, or awareness of existing solutions is provided. No indication of how Tang compares to other tools in this space.

Key Risks & Red Flags

  • No traction or revenue evidence: The project is described as a hackathon prototype with no data on adoption or monetization.
  • Unverified claims: All statements are self-reported and unverified, including the tool’s functionality and future plans.
  • Limited scope: The tool only supports a few tools at launch (Codex, Grok, OpenCode), with Cursor mentioned as a future target.
  • No commercial model: No indication of how Tang will be monetized or scaled beyond its initial release.

Diligence Questions To Ask The Founders

  1. What is the actual user feedback you’ve received from developers using Tang?
  2. How does Tang handle data privacy and security across different AI tools?
  3. Are there any technical limitations in connecting sessions between tools that could impact scalability?
  4. What are your plans for monetization or commercial viability beyond the initial release?
  5. Have you tested Tang with real-world workflows, or is it still experimental?
