AI for developers, without shipping your code to a shared workspace

For developers, the highest-value uses are explaining unfamiliar code, reviewing a diff you already wrote, and reasoning through a bug from real logs — with the ability to switch models mid-thread when one gets stuck.

Different models fail differently on code. ChatOTL lets you change model in the middle of a conversation, so a stuck thread gets a second opinion instead of a restart.

Everything is scoped to your account, and you can run against your own OpenAI-compatible endpoint if your codebase can't leave your infrastructure.

The loop that pays off

  • Explain: attach an unfamiliar file and ask what it does and what it assumes.
  • Review: paste your own diff and ask for failure modes, not praise.
  • Debug: paste the stack trace plus the relevant function and ask for hypotheses ranked by likelihood.
  • Branch: fork the reply when two fixes look plausible, then compare both threads.

Model switching, per task

Switch between models from OpenAI, Anthropic and Google — or your own OpenAI-compatible endpoint — in the middle of a conversation. Replies stream token by token with stop and regenerate on every turn, so a bad direction costs seconds.

Wire it into your agent clients

An OAuth-protected MCP server at /mcp lets clients such as Claude, Cursor or ChatGPT list, read, search and create your conversations as you. Row-level security still applies to every call.

Attachments that suit code

Attach up to 5 files per message (15 MB each). Source code, plain text, Markdown, CSV and JSON are extracted and passed inline, so the model sees the file rather than a summary of it.

Where it fits

Onboarding a codebase

Attach the entry point and ask for the control flow and hidden assumptions.

Pre-PR review

Paste the diff and ask for edge cases and failure modes before a human looks.

Log triage

Paste the trace and the suspect function, ask for ranked hypotheses.

Example prompts

  • Here's the diff. List the ways this breaks under concurrent writes.
  • Explain what this module assumes about its callers, then list what would break if those assumptions fail.
  • Given this stack trace and this function, rank the three most likely causes and how I'd disprove each.

Limitations

  • No web browsing, so it can't check a library's current docs or a breaking change for you — paste them in.
  • It doesn't act on external systems: no repo access, no running commands, no autonomous agents.
  • Generated code needs review and tests like any other; the model can be confidently wrong.

Frequently asked questions

Can I use my own API keys?

Yes. Provider keys are stored per account and never shared between users, and you can point ChatOTL at your own OpenAI-compatible endpoint instead.

Can it read my repository?

Not directly. It has no repo or filesystem access — you attach the specific files you want it to see, up to 5 per message at 15 MB each.

Does it work with Claude Desktop or Cursor?

Yes, through the OAuth-protected MCP server at /mcp. Connected clients can list, read, search and create your conversations as you, under the same row-level security.

Why switch models mid-conversation?

Because models fail differently. When one loops on a bug, switching keeps the accumulated context and gets a genuinely different attempt at it.
