Show HN: Git for LLMs – A context management interface
twigg.aiHi HN, we’re Jamie and Matti, co-founders of Twigg.
During our master’s we continually found the same pain points cropping up when using LLMs. The linear nature of typical LLMs interfaces - like ChatGPT and Claude - made it really easy to get lost without any easy way to visualise or navigate your project.
Worst of all, none of them are well suited for long term projects. We found ourselves spending days using the same chat, only for it to eventually break. Transferring context from one chat to another is also cumbersome. We decided to build something more intuitive to the ways humans think.
We started with two simple ideas. Enabling chat branching for exploring tangents, and an interactive tree diagram to allow for easy visualisation and navigation of your project.
Twigg has developed into an interface for context management - like “Git for LLMs”. We believe the input to a model - or the context - is fundamental to its performance. To extract the maximum potential of an LLM, we believe the users need complete control over exactly what context is provided to the model, which you can do using simple features like cut, copy and delete to manipulate your tree.
Through Twigg, you can access a variety of LLMs from all the major providers, like ChatGPT, Gemini, Claude, and Grok. Aside from a standard tiered subscription model (free, plus, pro), we also offer a Bring Your Own Key (BYOK) service, where you can plug and play with your own API keys.
Our target audience are technical users who use LLMs for large projects on a regular basis. If this sounds like you, please try out Twigg, you can sign up for free at https://twigg.ai/. We would love to get your feedback!
Msty has a pretty good interface for this as well. It actually has a ton of qol updates compared to the big webchat interfaces.
I tried it, I have tried a very similar but still different use case. I wonder if you have thoughts around how much of this is our own context management vs context management for the LLM. Ideally, I don't want to do any work for the LLM; it should be able to figure out from chat what 'branch' of the tree I'm exploring, and then the artifact is purely for one's own use.
Hi, matti here.
Very interesting you bring this up. It was quite a big point of discussion whilst jamie and I were building.
One of the big issues we faced with LLMs is that their attention gets diluted when you have a long chat history. This means that for large amounts of context, they often can't pick out the details your prompt relates to. I'm sure you've noticed this once your chat gets very long.
Instead of trying to develop an automatic system to descide what context your prompt should use (I.e which branch you're on), we opted to make organising your tree a very deliberate action. This gives you a lot more control over what the model sees, and ultimately how good the responses. As a bonus, if a model if playing up, you can go in and change the context it has by moving a node or two about.
Really good point though, and thanks for asking about it. I'd love to hear if you have any thoughts on ways you could get around it automatically.
something im wondering is, suppose you add or remove a chunk of context - what do you do to evaluate whether thata better or not, when the final resulting code or test run might be half an hour or an hpur later?
is the expectation that you will be running many branches of of context at the same time?
Yea, this really needed to happen. Idk if this specific branching type of interface will stand the test of time, but I'm glad to see people finally braving beyond the basic chat interface (which I think many of us forget was only ever meant to be a demo...yet it remains default and dominant).
Hi, matti here.
Appreciate the feedback. We agree there's definitely more work to be done on exactly how trees are represented to the user.
When I was using twigg to build itself, I often just used the side panel branch off when I needed to instead of using the tree diagram. The tree then kind of built itself.
Would be interested to hear if you prefer having the tree up on screen, or if you prefer the 'branch to the side' approach.
Ha! This looks really nice, and I'm right there with you on the context development UX being clunky to navigate.
A couple of weeks ago I built something very very similar, only for Obsidian, using the Obsidian Canvas and OpenRouter as my baseline components. Works really nicely - handles image uploads, autolayout with dagre.js, system prompts, context export to flat files, etc. Think you've inspired me to actually publish the repo :)
That's great to hear! Best of luck with it, let me know how it goes.
I definitely think that there is a lot of work to do with context management UX. For us, we use react flow for our graph, and we manage the context and its tree structure ourselves so it's completely model agnostic. The same goes for our RAG system, so we can plug and play with any model! Is that similar for you?
Would love to see that--haven't found a great LLM interface for obsidian yet.
The agent boom has been so good to React Flow.
Really cool! I’d want something like this for Claude code or other terminal based tools. Basically when working on code sometimes I already interrupt and resume the same session in multiple terminals so I can explore different pathways at the same time without the parallel sessions polluting one another. Currently this is really clunky in Claude Code.
Anyway, great project! Cheers.
Thanks! I totally agree, we want to add CLI agent integration! I often use Gemini CLI (as it's free), and it's so frustrating not being able to easily explore different tangents.
Would you prefer a terminal Claude-Code style integration, or would browser based CLI integration work too?
Imo I’d prefer terminal for this as well. Ie; if I could keep context specific to a branch, or even within a branch switch contexts.
Thanks for the feedback. We will add in CLI integration soon!
Could you please explain what you mean by "within branch" context switches?
The way Twigg works is you can choose exactly what prompt/output pairs (we call them nodes) are sent to the model. You can move 'nodes' from one branch to another. For example, if you do a bug fix in one branch, you can add the corrected solution as context to another branch by moving the node, whilst ignoring the irrelevant context spent trying to fix the bug.
This way you can specify exactly what context is in each branch.
Best of luck to you two! This is definitely a problem worth solving
... though I honestly do wish that the current LLM interfaces I use would just implement something like this. Maybe they could acquire you guys :D
I am using a graph based format which is stored as text file. It is as simple as possible: each node is a line, prefixed with node id, and containing inline node references. I am providing a sample right here:
---
[1] *Mind Map Format Overview* - A graph-based documentation format stored as plain text files where each node is a single line. The format leverages LLM familiarity with citation-style references from academic papers, making it natural to generate and edit [3]. It serves as a superset structure that can represent trees, lists, or any graph topology [4], scaling from small projects (<50 nodes) to complex systems (500+ nodes) [5]. The methodology is fully detailed in PROJECT_MIND_MAPPING.md with bootstrapping tools available at https://gist.github.com/horiacristescu/7942db247fdfb31d7150b....
[2] *Node Syntax Structure* - Each node follows the format: `[N] *Node Title* - node text with [N] references inlined` [1]. Nodes are line-oriented, allowing line-by-line loading and editing by AI models [3]. The inline reference syntax `[N]` creates bidirectional navigation between concepts, with links embedded naturally within descriptive text rather than as separate metadata [1][4]. This structure is both machine-parseable and human-readable, supporting grep-based lookups for quick node retrieval [3].
[3] *Technical Advantages* - The format enables line-by-line overwriting of nodes without complex parsing [2], making incremental updates efficient for both humans and AI agents [1]. Grep operations allow instant node lookup by ID or keyword without loading the entire file [2]. The text-based storage ensures version control compatibility, diff-friendly editing, and zero tooling dependencies [4]. LLMs generate this format naturally because citation syntax `[N]` mirrors academic paper references they've seen extensively during training [1][5].
[4] *Graph Topology Benefits* - Unlike hierarchical trees or linear lists, the graph structure allows many-to-many relationships between concepts [1]. Any node can reference any other node, creating knowledge clusters around related topics [2][3]. The format accommodates cyclic references for concepts that mutually depend on each other, captures cross-cutting concerns that span multiple subsystems, and supports progressive refinement where nodes are added to densify understanding [5]. This flexibility makes it suitable as a universal knowledge representation format [1].
[5] *Scalability and Usage Patterns* - Small projects typically need fewer than 50 nodes to capture core architecture, data flow, and key implementations [1]. Complex topics or large codebases can scale to 500+ nodes by adding specialized deep-dive nodes for algorithms, optimizations, and subsystems [4]. The methodology includes a bootstrap prompt (linked gist) for generating initial mind maps from existing codebases automatically [1]. Scale is managed through overview nodes [1-5] that serve as navigation hubs, with detail nodes forming clusters around major concepts [3][4]. The format remains navigable at any scale due to inline linking and grep-based search [2][3].
This is an interesting idea. Have you considered allowing different models for different chat nodes? My current very primitive solution is to have AI studio on one side of my screen and ChatGPT on the other, and me in the middle playing them off each other.
Yes, you can switch models any time for different chat nodes. So you can have different LLM review each others work, as an example. We currently have support for all the major models from ChatGPT, Gemini, Claude and Grok. Hope this helps
we implemented a similar idea some time back and it has proven quite useful: https://blog.codesolvent.com/2025/01/applying-forkjoin-model...
In Solvent, the main utility is allowing forked-off use of the same session without context pollution.
For instance a coding assistant session can be used to generate a checklist as a fork and then followed by the core task of writing code. This allows the human user to see the related flows (checklist gen,requirements gen,coding...etc) in chronological order without context pollution.
Great to hear others are thinking along similar lines!
Context pollution is a serious problem - I love that you use that term as well.
Have you had good feedback for your fork-off implementation?
Feel to "borrow" the term "context pollution" :)
Yes it has proven quite a useful feature. Primarily for the reason stated above, allowing users to get a full log of what's going on in the same session that the core task is taking place.
We also use it extensively to facilitate back-and-forth conversation with the agents, for instance a lot of our human-in-loop capabilities rely on the forking functionality...the scope of its utility has been frankly surprising :)
